Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Foreign Currency Translation The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany balances and transactions. iRobot has prepared the accompanying unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"). In the opinion of management, all adjustments necessary to the unaudited interim consolidated financial statements have been made to state fairly the Company's financial position. Interim results are not necessarily indicative of results for the full fiscal year or any future periods. The information included in this Form 10-Q should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in its Annual Report on Form 10-K for the fiscal year ended January 2, 2021, filed with the Securities and Exchange Commission on February 16, 2021. The Company operates and reports using a 52-53 week fiscal year ending on the Saturday closest to December 31. Accordingly, the Company’s fiscal quarters end on the Saturday that falls closest to the last day of the third month of each quarter. Recently Adopted Accounting Standards In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-12, "Income Taxes - Simplifying the Accounting for Income Taxes." The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles as well as clarifying and amending existing guidance to improve consistent application. The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis. The Company adopted the standard in the first quarter of 2021 and the adoption had no impact on the Company's consolidated financial statements. Recently Issued Accounting Standards From time to time, new accounting pronouncements are issued by FASB that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption. Use of Estimates The preparation of these financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses. These estimates and judgments include, but are not limited to, revenue recognition, including performance obligations, variable consideration and other obligations such as product returns and incentives; allowance for credit losses; product warranties; valuation of goodwill and acquired intangible assets; valuation of non-marketable equity investments; evaluating loss contingencies; accounting for stock-based compensation including performance-based assessments; and accounting for income taxes and related valuation allowances. The Company bases these estimates and judgments on historical experience, market participant fair value considerations, projected future cash flows and various other factors that the Company believes are reasonable under the circumstances. Actual results may differ from the Company’s estimates. As of April 3, 2021, the impact of the COVID-19 pandemic remains dynamic and the nature and extent of its full impact on the Company's financial and operational results will depend on several factors, including but not limited to, the duration and severity of the pandemic, advances in treatment and prevention, as well as the macroeconomic impact resulting from global responses to slow the spread of the pandemic. As a result, certain of our estimates and assumptions, including the allowance for credit losses and the valuation of non-marketable equity securities, including our impairment assessment, require increased judgment and carry a higher degree of variability and volatility, which could result in material changes to our estimates in future periods. Credit Losses The Company is exposed to credit losses primarily through sales of its products. The Company assesses each customer's ability to pay by conducting a credit review which includes consideration of established credit ratings or an internal assessment of the customer's creditworthiness based on an analysis of their financial information when a credit rating is not available. The Company monitors the credit exposure through active review of customer balances. The Company's expected loss methodology for accounts receivable is developed through consideration of factors including, but not limited to, historical collection experience, current customer credit ratings, current and future economic and market conditions and age of the receivable. Although the Company historically has not experienced significant credit losses as it relates to trade accounts receivable, the COVID-19 pandemic has caused uncertainty in some customer accounts. The Company recorded its estimate of credit losses, resulting in a decrease to the reserve and bad debt expense, of $2.1 million during the three months ended April 3, 2021. As of April 3, 2021 and January 2, 2021, the Company had an allowance for credit losses of $2.7 million and $4.8 million, respectively. Inventory Inventory is stated at the lower of cost or net realizable value with cost being determined using the first-in, first-out method. The Company writes down its inventory for estimated obsolescence or excess inventory based upon assumptions around market conditions and estimates of future demand. Adjustments to reduce inventory to net realizable value are recognized in cost of revenue and have not been significant for the periods presented. Inventory primarily consists of finished goods at April 3, 2021 and January 2, 2021. Strategic Investments The Company holds non-marketable equity securities as part of its strategic investments portfolio. The Company classifies the majority of these securities as equity securities without readily determinable fair values and measures these investments at cost, less any impairment, adjusted for observable price changes. These investments are valued using significant unobservable inputs or data in an inactive market and the valuation requires the Company's judgment due to the absence of market prices and inherent lack of liquidity. The estimated fair value is based on quantitative and qualitative factors including, but not limited to, subsequent financing activities by the investee and projected discounted cash flows. At April 3, 2021 and January 2, 2021, the Company's equity securities without readily determinable fair values totaled $17.5 million and $17.4 million, respectively, and are included in other assets on the consolidated balance sheets. On July 1, 2020, Teladoc Health, Inc. ("Teladoc") closed on its previously announced acquisition of InTouch Health, of which the Company held non-marketable equity securities. In exchange for its shares of InTouch Health, the Company received 0.2 million shares of Teladoc and recorded a gain of $38.6 million to other income, net during the second quarter of 2020. The Teladoc shares received were subject to time based contractual sales restrictions which expired in January 2021. These shares were accounted for as marketable equity securities and measured at fair value with unrealized gains and losses recognized in other income, net at the end of each reporting period. As a result, the Company entered into an economic hedge in July 2020 to reduce the Company's exposure to stock price fluctuations during the restricted period. During the three months ended April 3, 2021, the Company received net proceeds of $51.5 million related to the sale of Teladoc shares with gross proceeds of $60.1 million, net of settlement payment of $8.6 million for the related economic hedge. Net Income Per Share Basic income per share is calculated using the Company's weighted-average outstanding common shares. Diluted income per share is calculated using the Company's weighted-average outstanding common shares including the dilutive effect of stock awards as determined under the treasury stock method. The following table presents the calculation of both basic and diluted net income (loss) per share (in thousands, except per share amounts): Three Months Ended April 3, 2021 March 28, 2020 Net income (loss) $ 7,443 $ (18,135) Basic weighted-average common shares outstanding 28,257 28,297 Dilutive effect of employee stock awards 829 — Diluted weighted-average common shares outstanding 29,086 28,297 Net income (loss) per share - Basic $ 0.26 $ (0.64) Net income (loss) per share - Diluted $ 0.26 $ (0.64)

Revenue Recognition (Notes)

Revenue Recognition (Notes)	3 Months Ended

Revenue Recognition and Deferred Revenue [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue Recognition The Company primarily derives its revenue from the sale of consumer robots and accessories. The Company sells products directly to consumers through online stores and indirectly through resellers and distributors. Revenue is recognized upon transfer of control of promised products or services to customers, generally as title and risk of loss pass, in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is recognized only to the extent that it is probable that a significant reversal of revenue will not occur and when collection is considered probable. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue. Shipping and handling expenses are considered fulfillment activities and are expensed as incurred. The Company’s consumer robots are highly dependent on, and interrelated with, the embedded software and cannot function without the software. As such, the consumer robots are accounted for as a single performance obligation, and the revenue is recognized at a point in time when the control is transferred to distributors, resellers or directly to end customers through online stores. For certain consumer robots with Wi-Fi capability ("connected robots"), each sale represents an arrangement with multiple promises consisting of the robot, downloadable free app, cloud services and potential future unspecified software upgrades. The Company has determined that the app, cloud services and potential future unspecified software upgrades represent one promised service to the customer to enhance the functionality and interaction with the robot (referred to collectively as "Cloud Services"). For contracts that contain multiple performance obligations, the transaction price is allocated to each performance obligation based on a relative standalone selling price ("SSP"). The Company estimates SSP for items that are not sold separately, using market data if available or analysis of the cost of providing the products or services plus a reasonable margin. The transaction price allocated to the robots is recognized as revenue at a point in time when control is transferred and when collection is considered probable. The transaction price allocated to the Cloud Services is deferred and recognized on a straight-line basis over the estimated term of the Cloud Services. For contracts with a duration of greater than one year, the transaction price allocated to performance obligations that are unsatisfied as of April 3, 2021 and January 2, 2021 was $13.1 million and $11.5 million, respectively . The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. The Company’s products generally carry a one-year or two-year limited warranty that promises customers that delivered products are as specified. The Company does not consider these assurance-type warranties as a separate performance obligation and therefore, the Company accounts for such warranties under ASC 460, "Guarantees." During the fourth quarter of 2020, the Company began offering its customers the option to purchase an extended warranty for a fee. Amounts paid for the extended warranty plans are deferred and recognized as revenue on a straight-line basis over the service period. The Company provides limited rights of returns for direct-to-consumer sales generated through its online stores and certain resellers and distributors. The Company records an allowance for product returns based on specific terms and conditions included in the customer agreements or based on historical experience and the Company's expectation of future returns. In addition, the Company may provide other credits or incentives which are accounted for as variable consideration when estimating the amount of revenue to recognize. Where appropriate, these estimates take into consideration relevant factors such as the Company’s historical experience, current contractual requirements, specific known market events and forecasted inventory level in the channels. Overall, these reserves reflect the Company’s best estimates, and the actual amounts of consideration ultimately received may differ from the Company’s estimates. Returns and credits are estimated at the time of sale and updated at the end of each reporting period as additional information becomes available. As of April 3, 2021, the Company has reserves for product returns of $51.8 million and other credits and incentives of $78.3 million. As of January 2, 2021, the Company had reserves for product returns of $64.3 million and other credits and incentives of $142.2 million. Revenue recognized during the three months ended April 3, 2021 and March 28, 2020 related to performance obligations satisfied in a prior period was not material. Disaggregation of Revenue The following table provides information about disaggregated revenue by geographical region (in thousands): Three Months Ended April 3, 2021 March 28, 2020 United States $ 114,772 $ 81,967 EMEA 116,233 66,659 Japan 40,575 26,464 Other 31,681 17,445 Total revenue $ 303,261 $ 192,535 Contract Balances The following table provides information about receivables and contract liabilities from contracts with customers (in thousands): April 3, 2021 January 2, 2021 Accounts receivable, net $ 67,918 $ 170,526 Contract liabilities 14,986 17,700 The Company invoices customers based upon contractual billing schedules, and accounts receivable are recorded when the right to consideration becomes unconditional. Contract liabilities include deferred revenue associated with the Cloud Services and extended warranty plans as well as prepayments received from customers in advance of product shipments. The change in the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. During the three months ended April 3, 2021 and March 28, 2020, the Company recognize d $7.3 million an

Leases [Abstract]
Lessee, Operating Leases [Text Block]	Leases The Company's leasing arrangements primarily consist of operating leases for its facilities which include corporate, sales and marketing and research and development offices and equipment under various non-cancelable lease arrangements. For leases with terms greater than 12 months, the Company records the related right-of-use asset and lease obligation at the present value of lease payments over the term. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the lease term. The Company's leases typically include rental escalation clauses, renewal options and/or termination options that are factored into the determination of lease payments when appropriate. The Company does not separate lease and nonlease components of contracts and excludes all variable lease payments from the measurement of right-of-use assets and lease liabilities. The Company's variable lease payments generally include usage based nonlease components. The Company's lease agreements do not contain any residual value guarantees or restrictive covenants. The Company's existing leases do not provide a readily determinable implicit rate. Therefore, the Company estimates its incremental borrowing rate to discount the lease payments based on information available at December 30, 2018 (date of initial application) or the lease commencement date for new leases post adoption. At April 3, 2021, the Company's weighted average discount rate wa s 3.57% , while the weighted average remaining lease term was 8.14 ye ars. The components of lease expense were as follows (in thousands): Three Months Ended April 3, 2021 March 28, 2020 Operating lease cost $ 1,987 $ 2,355 Variable lease cost 895 1,122 Total lease cost $ 2,882 $ 3,477 Supplemental cash flow information related to leases was as follows (in thousands): Three Months Ended April 3, 2021 March 28, 2020 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 2,279 $ 2,021 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ — $ — Maturities of operating lease liabilities were as follows as of April 3, 2021 (in thousands): Remainder of 2021 $ 5,896 2022 8,590 2023 7,651 2024 6,595 2025 6,621 Thereafter 28,562 Total minimum lease payments $ 63,915 Less: imputed interest 8,955 Present value of future minimum lease payments $ 54,960 Less: current portion of operating lease liabilities (Note 6) 6,222 Long-term lease liabilities $ 48,738

These contracts typically have maturities o f three years or less. At April 3, 2021 and January 2, 2021, the Company had outstanding cash flow hedges with a total notional value of $397.8 million and $431.9 million, respectively. The Company also enters into economic hedges that are not designated as hedges from an accounting standpoint to reduce or eliminate the effects of foreign exchange rate changes typically related to short term trade receivables and payables. These contracts typically have maturities of twelve months or less. At April 3, 2021 and January 2, 2021, the Company had outstanding foreign currency economic hedges with a total notional value of $140.5 million a nd $192.2 million, respectively. As described in Note 2, during July 2020, the Company entered into a forward sale contract as an economic hedge to reduce the Company's exposure to stock price fluctuations on one of its marketable equity securities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings From time to time and in the ordinary course of business, the Company is subject to various claims, charges and litigation. The outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, which could materially affect our financial condition or results of operations. For the following litigation matters, a liability is not probable or the amount cannot be reasonably estimated and therefore accruals have not been made. On October 24, 2019, purported Company shareholder Miramar Firefighters’ Pension Fund filed a putative class action in the U.S. District Court for the Southern District of New York against the Company and certain of its directors and officers, captioned Miramar Firefighters’ Pension Fund v. iRobot Corporation, et al., No. 1:19-cv-09837. The case has been transferred to the U.S. District Court for the District of Massachusetts. A similar case captioned Campbell v. iRobot Corporation, et al., No. 1:19-cv-12483 was also filed in the U.S. District Court for the Southern District of New York and subsequently transferred to the U.S. District Court for the District of Massachusetts. On January 24, 2020, the Court consolidated the Miramar and Campbell cases (the consolidated cases together, the "Securities Class Action") and appointed a lead plaintiff and lead plaintiff's Counsel. On April 3, 2020, the plaintiff filed an amended complaint alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder based on allegedly false and misleading statements and omissions concerning the impact of competition and Section 301 tariffs on the Company’s financial performance, and the Company has filed a motion to dismiss the case. On March 15, 2021, the Court granted the Company’s motion to dismiss and therefore dismissed the Securities Class Action. On December 20, 2019, purported Company shareholders David Katz and Thomas Wightman, derivatively on behalf of iRobot Corporation, filed a complaint in the U.S. District Court for Southern District of New York against the Company and certain of its directors and officers, captioned David Katz and Thomas Wightman, on behalf of iRobot Corporation v. iRobot Corporation, et al., No. 1:19-cv-11692. The complaint alleges breaches of fiduciary duties, unjust enrichment, violations of Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 thereunder based on allegedly false and misleading statements and omissions concerning the Company's acquisitions of Sales on Demand Corporation and Robopolis SAS and the Company's subsequent financial performance. The complaint seeks, among other things, unspecified compensatory damages, including interest, in connection with the Company's allegedly inflated stock price, attorneys' fees and costs, and unspecified equitable/injunctive relief. This case has been transferred to the U.S. District Court for the District of Massachusetts. Similarly, additional derivative litigations -- namely: Robert Truman, on behalf of iRobot Corporation v. iRobot Corporation, et al., No. 1:20-cv-10034; Alexa Ruhfass, on behalf of iRobot Corporation v. iRobot Corporation, et al., No. 1:20-cv-10133; and William Tasco, derivatively on behalf of iRobot Corporation v. iRobot Corporation, et al., No. 1:20-cv-10253 - were filed in the U.S. District Court for the District of Massachusetts. All of these cases have been consolidated in a case captioned as In re iRobot Corporation Derivative litigation, No. 1:20-cv-10034. On May 4, 2021, the parties filed a joint stipulation with the U.S. District Court for the District of Massachusetts seeking dismissal of this case. Guarantees and Indemnification Obligations The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies and agrees to reimburse the indemnified party for losses incurred by the indemnified party, generally the Company’s customers, in connection with any patent, copyright, trade secret or other proprietary right infringement claim by any third party. The term of these indemnification agreements is generally perpetual any time after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of April 3, 2021 and January 2, 2021, respectively. Warranty The Company provides warranties on most products and has established a reserve for warranty obligations based on estimated warranty costs. The reserve is included as part of accrued expenses (Note 6) in the accompanying consolidated balance sheets. Activity related to the warranty accrual was as follows (in thousands): Three Months Ended April 3, 2021 March 28, 2020 Balance at beginning of period $ 24,392 $ 13,856 Provision 10,185 4,475 Warranty usage (10,673) (4,333) Balance at end of period $ 23,904 $ 13,998

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Foreign Currency Translation The accompanying consolidated financial statements include those of iRobot and its subsidiaries, after elimination of all intercompany balances and transactions. iRobot has prepared the accompanying unaudited consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"). In the opinion of management, all adjustments necessary to the unaudited interim consolidated financial statements have been made to state fairly the Company's financial position. Interim results are not necessarily indicative of results for the full fiscal year or any future periods. The information included in this Form 10-Q should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in its Annual Report on Form 10-K for the fiscal year ended January 2, 2021, filed with the Securities and Exchange Commission on February 16, 2021.
Recent Accounting Pronouncements	Recently Adopted Accounting Standards In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2019-12, "Income Taxes - Simplifying the Accounting for Income Taxes." The ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles as well as clarifying and amending existing guidance to improve consistent application. The amendments to this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. Depending on the amendment, adoption may be applied on the retrospective, modified retrospective or prospective basis. The Company adopted the standard in the first quarter of 2021 and the adoption had no impact on the Company's consolidated financial statements. Recently Issued Accounting Standards From time to time, new accounting pronouncements are issued by FASB that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.
Use of Estimates	Use of Estimates The preparation of these financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses. These estimates and judgments include, but are not limited to, revenue recognition, including performance obligations, variable consideration and other obligations such as product returns and incentives; allowance for credit losses; product warranties; valuation of goodwill and acquired intangible assets; valuation of non-marketable equity investments; evaluating loss contingencies; accounting for stock-based compensation including performance-based assessments; and accounting for income taxes and related valuation allowances. The Company bases these estimates and judgments on historical experience, market participant fair value considerations, projected future cash flows and various other factors that the Company believes are reasonable under the circumstances. Actual results may differ from the Company’s estimates. As of April 3, 2021, the impact of the COVID-19 pandemic remains dynamic and the nature and extent of its full impact on the Company's financial and operational results will depend on several factors, including but not limited to, the duration and severity of the pandemic, advances in treatment and prevention, as well as the macroeconomic impact resulting from global responses to slow the spread of the pandemic. As a result, certain of our estimates and assumptions, including the allowance for credit losses and the valuation of non-marketable equity securities, including our impairment assessment, require increased
Credit Losses	Credit Losses The Company is exposed to credit losses primarily through sales of its products. The Company assesses each customer's ability to pay by conducting a credit review which includes consideration of established credit ratings or an internal assessment of the customer's creditworthiness based on an analysis of their financial information when a credit rating is not available. The Company monitors the credit exposure through active review of customer balances. The Company's expected loss methodology for accounts receivable is developed through consideration of factors including, but not limited to, historical collection experience, current customer credit ratings, current and future economic and market conditions and age of the receivable. Although the Company historically has not experienced significant credit losses as it relates to trade accounts receivable, the COVID-19 pandemic has caused uncertainty in some customer accounts. The Company recorded its estimate of credit losses, resulting in a decrease to the reserve and bad debt expense, of $2.1 million during the three months ended April 3, 2021. As of April 3, 2021 and January 2, 2021, the Company had an allowance for credit losses of $2.7 million and $4.8 million, respectively.
Inventory, Policy	Inventory Inventory is stated at the lower of cost or net realizable value with cost being determined using the first-in, first-out method. The Company writes down its inventory for estimated obsolescence or excess inventory based upon assumptions around market conditions and estimates of future demand. Adjustments to reduce inventory to net realizable value are recognized in cost of revenue and have not been significant for the periods presented. Inventory primarily consists of finished goods at April 3, 2021 and January 2, 2021.
Investment, Policy [Policy Text Block]	Strategic Investments The Company holds non-marketable equity securities as part of its strategic investments portfolio. The Company classifies the majority of these securities as equity securities without readily determinable fair values and measures these investments at cost, less any impairment, adjusted for observable price changes. These investments are valued using significant unobservable inputs or data in an inactive market and the valuation requires the Company's judgment due to the absence of market prices and inherent lack of liquidity. The estimated fair value is based on quantitative and qualitative factors including, but not limited to, subsequent financing activities by the investee and projected discounted cash flows. At April 3, 2021 and January 2, 2021, the Company's equity securities without readily determinable fair values totaled $17.5 million and $17.4 million, respectively, and are included in other assets on the consolidated balance sheets. On July 1, 2020, Teladoc Health, Inc. ("Teladoc") closed on its previously announced acquisition of InTouch Health, of which the Company held non-marketable equity securities. In exchange for its shares of InTouch Health, the Company received 0.2 million shares of Teladoc and recorded a gain of $38.6 million to other income, net during the second quarter of 2020. The Teladoc shares received were subject to time based contractual sales restrictions which expired in January 2021. These shares were accounted for as marketable equity securities and measured at fair value with unrealized gains and losses recognized in other income, net at the end of each reporting period. As a result, the Company entered into an economic hedge in July 2020 to reduce the Company's exposure to stock price fluctuations during the restricted period. During the three months ended April 3, 2021, the Company received net proceeds of $51.5 million related to the sale of Teladoc shares with gross proceeds of $60.1 million, net of settlement payment of $8.6 million for the related economic hedge.
Net Income Per Share	Net Income Per Share Basic income per share is calculated using the Company's weighted-average outstanding common shares. Diluted income per share is calculated using the Company's weighted-average outstanding common shares including the dilutive effect of stock awards as determined under the treasury stock method.
