Named Executive Officers, Footnote [Text Block] | Amounts represent average total compensation reported in the Summary Compensation Table and average “compensation actually paid” to our named executive officers (excluding our PEO) for the relevant fiscal year, which includes the individuals indicated in the table below for each fiscal year:

Peer Group Issuers, Footnote [Text Block] | We used the 2022 peer group used for compensation benchmarking purposes to illustrate the value of initial fixed $100 investment. As of December 31, 2022, there were fifteen companies in our 2022 peer group used for compensation benchmarking purposes, which are: 3D Systems Corporation, Alarm.com Holdings, Inc., Azenta Inc., Coherent Corp., Dolby Laboratories, Inc., Faro Technologies, Inc., Garmin Ltd., GoPro, Inc., Logitech International S.A., NETGEAR, Inc., Novanta Inc., Roku, Inc., Sonos, Inc., Trimble Inc. and Universal Electronics Inc. For these purposes, we removed Poly (Plantronics, Inc.) from the 2022 peer group disclosed in the CD&A as they were acquired by Hewlett Packard on August 29, 2022. |  |

Adjustment To PEO Compensation, Footnote [Text Block] | SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine “compensation actually paid” as reported in the Pay Versus Performance Table. Compensation actually paid does not necessarily represent cash and/or equity value transferred to the applicable named executive officer without restriction, but rather is a value calculated in accordance with Item 402(v) of Regulation S-K.The following tables show the adjustments made to our PEO’s total compensation as reported in the Summary Compensation Table to calculate “compensation actually paid” for each fiscal year: PEO Summary Compensation Table Total to Compensation Actually Paid Reconciliation

Compensation Actually Paid vs. Total Shareholder Return [Text Block] | We use a mix of performance measures in our annual and long-term incentive programs to align executive pay with Company performance. Our named executive officers’ target total compensation is heavily weighted towards short and long-term performance with performance goals aligned with stockholders’ interest. We believe the Pay Versus Performance tables show the alignment between compensation actually paid to the named executive officers and the Company’s performance, consistent with our compensation philosophy as described in our CD&A on page 32. Specifically, a large portion of the named executive officers’ compensation for 2022 was earned based on relative TSR against the Index and as such the PEO and non-PEO named executive officers’ “compensation actually paid” each year was generally aligned with our relative TSR performance and increased when our relative TSR performance increased but declined when our relative TSR performance declined. Our revenue and operating income performance over the period also generally align with compensation actually paid. |  |
Compensation Actually Paid vs. Net Income [Text Block] | As shown in the Pay Versus Performance table, the Company’s net income has decreased while the PEO and other named executive officers’ compensation actually paid declined significantly in 2021 from 2020 with some recovery in 2022. This is due in large part to the significant emphasis the Company places on equity incentives, which are sensitive to changes in stock price. The Company does not use net income to determine compensation levels or incentive plan payouts. |  |

Total Shareholder Return Vs Peer Group [Text Block] | As outlined in our CD&A on page 35 we do not have any true consumer robotic peer companies that are publicly traded. The pandemic created some volatility within our peer group’s TSR and while our TSR performance was behind the peer group the end of 2020 and 2021, our TSR recovered at the end of 2022. This performance generally aligned well with compensation actually paid to our named executive officers.

Additional 402(v) Disclosure [Text Block] | When reconciling to GAAP operating income, non-GAAP operating income reflects adjustments for amortization of acquired tangible assets, stock-based compensation, tariff refunds, net merger, acquisition, and divestiture expense (income), IP litigation expense, and restructuring/other. To further show the alignment of pay and performance, we have shown our PEO’s realizable pay over the past three years to supplement the Pay Versus Performance table. This shows a similar story to compensation actually paid, where pay has fallen below target when we fall short of compensatory performance goals. |  |

Non-GAAP Measure Description [Text Block] | Relative TSR is defined as the percentage by which our TSR is greater than or less than the Russell 2000 Index. While we consider numerous financial and non-financial performance measures for the purpose of evaluating and determining executive compensation, we consider relative TSR against the Index (which is the primary measure used to determine for the number of PSUs earned for purposes of the 2022 PSU awards) to be the most important performance measure used by the Company to link compensation actually paid to the named executive officers for fiscal year 2022 to Company performance. |  |
