Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Basis of Presentation – The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the Securities and Exchange Commission (“SEC”) requirements for interim reporting, which allows certain footnotes and other financial information normally required by accounting principles generally accepted in the United States of America to be condensed or omitted. In our opinion, the Condensed Consolidated Financial Statements contain all adjustments (consisting of only normal recurring adjustments) necessary for the fair presentation of our financial position and results of operations. These statements should be read in conjunction with the Consolidated Financial Statements and Notes included in our annual report on Form 10-K for the year ended December 31, 2016 . The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Equity Method Investment – Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in Other Assets on the Condensed Consolidated Balance Sheets. Under this method of accounting, our share of the net earnings or losses of the investee are presented as a component of Other Income (Expense) on the Condensed Consolidated Statements of Operations. The details regarding our equity method investment in i-team North America B.V., a joint venture that will operate as the distributor of the i-mop in North America, are further described in Note 3. New Accounting Pronouncements – In accordance with Accounting Standards Update ("ASU") No. 2016-09, C ompensation–Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , all excess tax benefits and tax deficiencies are recorded as a component of the provision for income taxes in the reporting period in which they occur. Additionally, we present excess tax benefits along with other income tax cash flows on the Condensed Consolidated Statements of Cash Flows as an operating activity rather than, as previously required, a financing activity. For further details regarding the implementation of this ASU and the impact on our financial statements, see Note 2. We documented the summary of significant accounting policies in the Notes to the Consolidated Financial Statements of our annual report on Form 10-K for the fiscal year ended December 31, 2016 . Other than the accounting policies noted above, there have been no material changes to our accounting policies since the filing of that report.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Newly Adopted Accounting Pronouncements	2. Newly Adopted Accounting Pronouncements On March 30, 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-09, C ompensation–Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which amends Accounting Standards Codification ("ASC") Topic 718, Compensation – Stock Compensation. ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the Condensed Consolidated Statements of Cash Flows. Under the new standard, all excess tax benefits and tax deficiencies are recorded as a component of the provision for income taxes in the reporting period in which they occur. Additionally, ASU 2016-09 requires that the Company present excess tax benefits along with other income tax cash flows on the Condensed Consolidated Statements of Cash Flows as an operating activity rather than, as previously required, a financing activity. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016. We have adopted ASU 2016-09 effective January 1, 2017 on a prospective basis where permitted by the new standard. As a result of this adoption: • We recognized discrete tax benefits of $402 in the income taxes line item of our Condensed Consolidated Statements of Operations for the three months ended March 31, 2017 related to excess tax benefits upon vesting or settlement in that period. • We elected to adopt the cash flow presentation of the excess tax benefits prospectively where the tax benefits are classified along with other income tax cash flows as operating cash flows in 2017. Our prior year's excess tax benefits are recognized as financing cash flows; however, other income tax cash flows are classified as operating cash flows. • We have elected to account for forfeitures as they occur, rather than electing to estimate the number of share-based awards expected to vest to determine the amount of compensation cost to be recognized in each period. The difference of such change is immaterial. • We excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of our diluted earnings per share for the three months ended March 31, 2017.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments and Joint Ventures Disclosure [Text Block]	3. Investment in Joint Venture On February 13, 2017, the Company, through a Dutch subsidiary, and i-team Global, a Future Cleaning Technologies, B.V. company headquartered in The Netherlands, announced the January 1, 2017 formation of i-team North America B.V., a joint venture that will operate as the distributor of the i-mop in North America. The joint venture will begin selling and servicing the i-mop in the second quarter of 2017. The Company owns a 50% ownership interest in the joint venture and will account for the joint venture using the equity method of accounting. In March 2017, the Company issued a $1,500 loan to the joint venture and, as a result, recorded a long-term note receivable in Other Assets on the Condensed Consolidated Balance Sheets.

Management Action

Restructuring and Related Activities [Abstract]
Management Actions	4. Management Action During the first quarter of 2017, we implemented a restructuring action to better align our global resources and expense structure with a lower growth global economic environment. The pre-tax charge of $8,018 , including other associated costs of $961 , consisted primarily of severance and was included within Selling and Administrative Expense in the Condensed Consolidated Statements of Operations. The charge impacted our Americas, Europe, Middle East and Africa ("EMEA") and Asia Pacific ("APAC") operating segments. We believe the anticipated savings will offset the pre-tax charge in approximately one year from the date of the action. We do not expect additional costs will be incurred related to this restructuring action. A reconciliation to the ending liability balance of severance and related costs as of March 31, 2017 is as follows: Severance and Related Costs Q1 2017 restructuring action $ 7,057 Cash payments (1,821 ) March 31, 2017 balance $ 5,236

Business Combinations [Abstract]
Acquisitions	5. Acquisitions On July 28, 2016 , pursuant to an asset purchase agreement and real estate purchase agreement with Crawford Laboratories, Inc. and affiliates thereof ("Sellers") , we acquired selected assets and liabilities of the Seller's commercial floor coatings business, including the Florock ® Polymer Flooring brand ("Florock"). Florock manufactures commercial floor coatings systems in Chicago, IL. The purchase price was $11,843 , including working capital and other adjustments, and is comprised of $10,965 paid at closing, with the remaining $878 paid in two installments. We paid the first installment of $575 on October 14, 2016. The remaining amount was paid during the three months ended March 31, 2017 . On September 1, 2016 , we acquired selected assets and liabilities of Dofesa Barrido Mecanizado ("Dofesa") which was our largest distributor in Mexico over many decades. The operations are based in Aguascalientes, Mexico, and their addition allows us to expand our sales and service network in an important market. The purchase price was $5,000 less assumed liabilities of $3,448 , subject to customary working capital adjustments. The net purchase price of $1,552 is comprised of $1,202 paid at closing, and a value added tax of $191 , with the remaining $350 subject to working capital adjustments. The working capital adjustment is not yet finalized, but we do not expect to pay additional cash beyond the cash already paid. The acquisitions have been accounted for as business combinations and the results of their operations have been included in the Condensed Consolidated Financial Statements since their respective dates of acquisition. The impact of the incremental revenue and earnings recorded as a result of the acquisitions are not material to our Condensed Consolidated Financial Statements. The purchase price allocations for the Florock acquisition are complete with the exception of the preliminary valuation of Plant and Equipment which is expected to be complete by the end of the second quarter of 2017. The purchase price allocations for the Dofesa acquisition are complete except for a preliminary valuation of Intangible Assets and finalization of the working capital adjustment. We expect our valuation will be complete in the second quarter of 2017. The preliminary components of the purchase price of the business combinations described above have been allocated as follows: Current Assets $ 5,928 Property, Plant and Equipment, net 4,359 Identified Intangible Assets 3,731 Goodwill 3,837 Other Assets 7 Total Assets Acquired 17,862 Current Liabilities 4,764 Other Liabilities 53 Total Liabilities Assumed 4,817 Net Assets Acquired $ 13,045

Disposal Group, Not Discontinued Operation, Disposal Disclosures [Abstract]
Divestiture	6. Divestiture On January 19, 2016 , we signed a Business Purchase Agreement (“BPA”) with Green Machines International GmbH and Green Machine Sweepers UK Limited ("the Buyers"), subsidiaries of M&F Management and Financing GmbH, which is also the parent company of the master distributor of our products in Central Eastern Europe, Middle East and Africa, TCS EMEA GmbH, for the sale of our Green Machines outdoor city cleaning line. The sale closed on January 31, 2016 . Including working capital adjustments, the aggregate consideration for the Green Machines business was $5,774 . For additional information regarding the sale of our Green Machines outdoor city cleaning line, the distributor agreement with the Buyers and the subsequent amendments to the distributor agreement and BPA, refer to Note 4 of our Consolidated Financial Statements as disclosed in our 2016 annual report on Form 10-K for the year ended December 31, 2016 . In the first three months of 2016 , as a result of this divestiture, we recorded a pre-tax loss of $62 in our (Loss) Profit from Operations in the Condensed Consolidated Statements of Operations. The impact of the recorded loss and the sale of Green Machines was not material to our earnings as Green Machines only accounted for approximately two percent of our total sales. We have identified Green Machines International GmbH as a variable interest entity (“VIE”) and have performed a qualitative assessment to determine if Tennant is the primary beneficiary of the VIE. We have determined that we are not the primary beneficiary of the VIE and consolidation of the VIE is not considered necessary.

Product Warranties Disclosures [Abstract]
Warranty	10. Warranty We record a liability for warranty claims at the time of sale. The amount of the liability is based on the trend in the historical ratio of claims to sales, the historical length of time between the sale and resulting warranty claim, new product introductions and other factors. Warranty terms on machines generally range from one to four years. However, the majority of our claims are paid out within the first six to nine months following a sale. The majority of the liability for estimated warranty claims represents amounts to be paid out in the near term for qualified warranty issues, with immaterial amounts reserved to be paid for older equipment warranty issues. The changes in warranty reserves for the three months ended March 31, 2017 and 2016 were as follows: Three Months Ended March 31 2017 2016 Beginning balance $ 10,960 $ 10,093 Additions charged to expense 2,072 2,488 Foreign currency fluctuations 50 60 Claims paid (2,800 ) (2,766 ) Ending balance $ 10,282 $ 9,875

Derivative Instruments and Hedging Activities Disclosure [Text Block]	11. Derivatives Hedge Accounting and Hedging Programs We recognize all derivative instruments as either assets or liabilities in our Condensed Consolidated Balance Sheets and measure them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. We evaluate hedge effectiveness on our hedges that are designated and qualify for hedge accounting at the inception of the hedge prospectively, as well as retrospectively, and record any ineffective portion of the hedging instruments in Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Operations. The time value of purchased contracts is recorded in Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Operations. Balance Sheet Hedging – Hedges of Foreign Currency Assets and Liabilities We hedge our net recognized foreign currency denominated assets and liabilities with foreign exchange forward contracts to reduce the risk that the value of these assets and liabilities will be adversely affected by changes in exchange rates. These contracts hedge assets and liabilities that are denominated in foreign currencies and are carried at fair value as either assets or liabilities on the Condensed Consolidated Balance Sheets with changes in the fair value recorded to Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Operations. These contracts do not subject us to material balance sheet risk due to exchange rate movements because gains and losses on these derivatives are intended to offset gains and losses on the assets and liabilities being hedged. At March 31, 2017 and December 31, 2016 , the notional amounts of foreign currency forward exchange contracts outstanding not designated as hedging instruments were $49,026 and $42,866 , respectively. During the first quarter of 2017, in connection with our acquisition of IPC Group, we entered into a foreign currency option contract not designated as a hedging instrument for a notional amount of €180,000 , or $193,500 . There were no outstanding foreign currency option contracts not designated as hedging instruments as of December 31, 2016 . Cash Flow Hedging – Hedges of Forecasted Foreign Currency Transactions In countries outside the U.S., we transact business in U.S. dollars and in various other currencies. We may use foreign exchange option contracts or forward contracts to hedge certain cash flow exposures resulting from changes in these foreign currency exchange rates. These foreign exchange contracts, carried at fair value, have maturities of up to one year . We enter into these foreign exchange contracts to hedge a portion of our forecasted foreign currency denominated revenue in the normal course of business, and accordingly, they are not speculative in nature. The notional amounts of outstanding foreign currency forward contracts designated as cash flow hedges were $2,925 and $2,127 as of March 31, 2017 and December 31, 2016 , respectively. The notional amounts of outstanding foreign currency option contracts designated as cash flow hedges were $8,220 and $8,522 as of March 31, 2017 and December 31, 2016 , respectively. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on hedged transactions. We record changes in the fair value of these cash flow hedges in Accumulated Other Comprehensive Loss in our Condensed Consolidated Balance Sheets, until the forecasted transaction occurs. When the forecasted transaction occurs, we reclassify the related gain or loss on the cash flow hedge to Net Sales in our Condensed Consolidated Statements of Operations. In the event the hedge becomes ineffective, the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, we reclassify the gain or loss on the related cash flow hedge from Accumulated Other Comprehensive Loss to Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Operations at that time. If we do not elect hedge accounting, or the contract does not qualify for hedge accounting treatment, the changes in fair value from period to period are recorded in Net Foreign Currency Transaction Losses in our Condensed Consolidated Statements of Operations. The fair value of derivative instruments on our Condensed Consolidated Balance Sheets as of March 31, 2017 and December 31, 2016 were as follows: March 31, 2017 December 31, 2016 Fair Value Asset Derivatives Fair Value Liability Derivatives Fair Value Asset Derivatives Fair Value Liability Derivatives Derivatives designated as hedging instruments: Foreign currency option contracts (1) $ 98 $ — $ 184 $ — Foreign currency forward contracts (1) — 9 — 13 Derivatives not designated as hedging instruments: Foreign currency option contracts (1) — 1,132 — — Foreign currency forward contracts (1) $ 5 $ 520 $ 12 $ 162 (1) Contracts that mature within the next 12 months are included in Other Current Assets and Other Current Liabilities for asset derivatives and liabilities derivatives, respectively, on our Condensed Consolidated Balance Sheets. As of March 31, 2017 , we anticipate reclassifying approximately $209 of losses from Accumulated Other Comprehensive Loss to net earnings during the next 12 months. The effect of foreign currency derivative instruments designated as cash flow hedges and of foreign currency derivative instruments not designated as hedges in our Condensed Consolidated Statements of Operations for the three months ended March 31, 2017 was as follows: Three Months Ended March 31, 2017 Foreign Currency Option Contracts Foreign Currency Forward Contracts Derivatives in cash flow hedging relationships: Net loss recognized in Other Comprehensive Income (Loss), net of tax (1) $ (90 ) $ (17 ) Net loss reclassified from Accumulated Other Comprehensive Loss into earnings, net of tax (2) (42 ) (19 ) Net (loss) gain recognized in earnings (3) (1 ) 2 Derivatives not designated as hedging instruments: Net loss recognized in earnings (4) $ (1,132 ) $ (1,368 ) The effect of foreign currency derivative instruments designated as cash flow hedges and of foreign currency derivative instruments not designated as hedges in our Condensed Consolidated Statements Operations for the three months ended March 31, 2016 was as follows: Three Months Ended March 31, 2016 Foreign Currency Option Contracts Foreign Currency Forward Contracts Derivatives in cash flow hedging relationships: Net loss recognized in Other Comprehensive Income (Loss), net of tax (1) $ (186 ) $ (36 ) Net gain reclassified from Accumulated Other Comprehensive Loss into earnings, net of tax (2) — 58 Net loss recognized in earnings (3) (6 ) — Derivatives not designated as hedging instruments: Net loss recognized in earnings (4) $ — $ (1,691 ) (1) Net change in the fair value of the effective portion classified in Other Comprehensive Income (Loss).

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	12. Fair Value Measurements Estimates of fair value for financial assets and financial liabilities are based on the framework established in the accounting guidance for fair value measurements. The framework defines fair value, provides guidance for measuring fair value and requires certain disclosures. The framework discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). The framework utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: • Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. • Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions. Our population of assets and liabilities subject to fair value measurements at March 31, 2017 is as follows: Fair Value Level 1 Level 2 Level 3 Assets: Foreign currency forward exchange contracts $ 5 $ — $ 5 $ — Foreign currency option contracts 98 — 98 — Total Assets $ 103 $ — $ 103 $ — Liabilities: Foreign currency forward exchange contracts $ 529 $ — $ 529 $ — Foreign currency option contracts $ 1,132 — 1,132 — Total Liabilities $ 1,661 $ — $ 1,661 $ — Our foreign currency forward and option exchange contracts are valued using observable Level 2 market expectations at the measurement date and standard valuation techniques to convert future amounts to a single present value amount. Further details regarding our foreign currency forward exchange and option contracts are discussed in Note 11. The carrying amounts reported in the Condensed Consolidated Balance Sheets for Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Other Current Assets, Accounts Payable and Other Current Liabilities approximate fair value due to their short-term nature. The fair value of our Long-Term Debt approximates cost based on the borrowing rates currently available to us for bank loans with similar terms and remaining maturities. From time to time, we measure certain assets at fair value on a non-recurring basis, including evaluation of long-lived assets, goodwill and other intangible assets for impairment using company-specific assumptions that would fall within Level 3 of the fair value hierarchy.

We are generally no longer subject to U.S. federal tax examinations for taxable years before 2013 and, with limited exceptions, state and foreign income tax examinations for taxable years before 2012 . We recognize potential accrued interest and penalties related to unrecognized tax benefits in Income Tax (Benefit) Expense. In addition to the liability of $2,635 for unrecognized tax benefits as of March 31, 2017 , there was approximately $518 for accrued interest and penalties. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of March 31, 2017 was $2,250 . To the extent interest and penalties are not assessed with respect to uncertain tax positions, amounts accrued will be revised and reflected as an adjustment of the Income Tax (Benefit) Expense. We are currently undergoing income tax examinations in various state and foreign jurisdictions covering 2012 to 2014 . Although the final outcome of these examinations cannot be currently determined, we believe that we have adequate reserves with respect to these examinations.

The 2017 Credit Agreement provides the Company and certain of our foreign subsidiaries access to a senior secured credit facility until April 4, 2022 , consisting of a multi-tranche term loan facility in an amount up to $400,000 and a revolving facility in an amount up to $200,000 with an option to expand the revolving facility by $150,000 , with the consent of the lenders willing to provide additional borrowings in the form of increases to their revolving facility commitment or funding of incremental term loans. Borrowings may be denominated in U.S. dollars or certain other currencies. The fee for committed funds under the revolving facility of the 2017 Credit Agreement ranges from an annual rate of 0.175% to 0.35% , depending on the Company’s leverage ratio. Borrowings denominated in U.S. dollars under the 2017 Credit Agreement bear interest at a rate per annum equal to (a) the greatest of (i) the prime rate, (ii) the federal funds rate plus 0.50% and (iii) the adjusted LIBOR rate for a one month period, but in any case, not less than 0% , plus, in any such case, 1.00% , plus an additional spread of 0.075% to 0.90% for revolving loans and 0.25% to 1.25% for term loans, depending on the Company’s leverage ratio, or (b) the LIBOR Rate, as adjusted for statutory reserve requirements for eurocurrency liabilities, but in any case, not less than 0% , plus an additional spread of 1.075% to 1.90% for revolving loans and 1.25% to 2.25% for term loans, depending on the Company’s leverage ratio.

Further, the 2017 Credit Agreement contains certain financial covenants. The full terms and conditions of the credit facility are set forth in the 2017 Credit Agreement. A copy of the 2017 Credit Agreement was filed as Exhibit 10.1 to the Company's Current Report on Form 8-K filed April 5, 2017 and is incorporated by reference herein. Upon entry into the 2017 Credit Agreement, the Company repaid all obligations under and terminated our prior Credit Agreement. IPC Acquisition On April 6, 2017 , we completed the acquisition of IP Cleaning S.p.A. and its subsidiaries ("IPC Group”) , pursuant to the terms of the Share Purchase Agreement with Ambienta SGR S.p.A. (acting as the management company of the closed-end funds named Ambienta I, Ambienta II and Ambienta II-bis), Federico De Angelis, Pietro Corsano Annibaldi, Antonio Perosa and Giulio Vernazza, which was entered into on February 22, 2017. The $353,000 ( €330,000 ) purchase price for the acquisition of the IPC Group was funded through the 2017 Credit Agreement. We were not able to include certain required disclosures in this Quarterly Report on Form 10-Q for the three months ended March 31, 2017 because the information necessary to complete the preliminary purchase price allocation related to the acquisition was not yet available. We intend to include such disclosures in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2017 and any subsequent filings as necessary. Issuance of 5.625% Senior Notes due 2025 On April 18, 2017 , we issued and sold $300,000 in aggregate principal amount of our 5.625% Senior Notes due 2025 (the “Notes”), pursuant to an Indenture, dated as of April 18, 2017, among the Company, the Guarantors (as defined therein), and Wells Fargo Bank, National Association, a national banking association, as trustee. The Notes are guaranteed by Tennant Coatings, Inc. and Tennant Sales and Service Company (collectively, the “Guarantors”), which are wholly owned subsidiaries of the Company. The Notes will mature on May 1, 2025 . Interest on the Notes will accrue at the rate of 5.625% per annum and will be payable semiannually in cash on each May 1 and November 1, commencing on November 1, 2017. We used the net proceeds from this offering to refinance a $300,000 term loan that was borrowed by it as part of the financing for the acquisition of the IPC Group and to pay related fees and expenses. The full terms and conditions of the Indenture are set forth in Exhibit 4.1 to the Company's Current Report on Form 8-K filed April 24, 2017 and is incorporated by reference herein.

Morgan Securities LLC (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the Company agreed (1) to use its commercially reasonable efforts to consummate an exchange offer to exchange the Notes for new registered notes (the “exchange notes”), with terms substantially identical in all material respects with the Notes (except that the exchange notes will not contain terms with respect to additional interest, registration rights or transfer restrictions) and (2) if required, to have a shelf registration statement declared effective with respect to resales of the Notes. If the Company fails to satisfy its obligations under the Registration Rights Agreement within 360 days , it will be required to pay additional interest to the holders of the Notes under certain circumstances. The Registration Rights Agreement is incorporated by reference to Exhibit 4.2 to the Company's Current Report on Form 8-K filed April 24, 2017.

In our opinion, the Condensed Consolidated Financial Statements contain all adjustments (consisting of only normal recurring adjustments) necessary for the fair presentation of our financial position and results of operations. These statements should be read in conjunction with the Consolidated Financial Statements and Notes included in our annual report on Form 10-K for the year ended December 31, 2016 . The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year.
Equity Method Investment	Equity Method Investment – Investments in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in Other Assets on the Condensed Consolidated Balance Sheets. Under this method of accounting, our share of the net earnings or losses of the investee are presented as a component of Other Income (Expense) on the Condensed Consolidated Statements of Operations. The details regarding our equity method investment in i-team North America B.V., a joint venture that will operate as the distributor of the i-mop in North America, are further described in Note 3.
