Thank you Colin. As Andy mentioned earlier, my review of our financial results and outlook will be done on a non-GAAP basis. So unless stated otherwise each mention of gross margin, operating expense, operating income and loss, operating profit margin, effective tax rate and net income and loss per share will mean the corresponding non-GAAP metric. All quarterly comparisons are against the fourth quarter of 2020 and all full year comparisons are against 2020 unless otherwise noted. iRobot's fourth quarter 2021 financial results were within the ranges we outlined on the Q3 call in October. Total Q4 revenue of $455 million declined 16%. In addition to semiconductor chip constraints that impacted second half 2021 production levels, we were unable to recognize more than $35 million in fourth quarter orders due to shipping delays. These delays resulted primarily from a combination of port congestion, labor shortages at warehouses, and a major snowstorm in the Pacific Northwest during the last week of the quarter. The delays caused many of these orders to miss key promotional windows, although some were fulfilled in the first quarter of 2022. Our commercial teams are working closely with retailers to sell that inventory over the coming quarters as they refine their 2022 promotional activities. Geographically strong 19% growth in Japan in the fourth quarter was offset by a 29% decrease in the US and a 2% decrease in EMEA. From a product mix perspective, Roomba represented 90% of our Q4 revenue mix with Braava making up the remainder. Our fourth quarter DTC sales declined slightly as strong growth in EMEA and Japan was offset by lower sales in the Americas as we lapped an exceptionally strong quarter a year ago. Our gross margin of 27.8% in Q4 declined 13 percentage points from the prior year and was below our target. The year-over-year decrease primarily reflected five percentage points associated with higher air and oceanic transportation, four percentage points associated with tariffs with the bulk of the remainder split between changes in pricing and promotion, higher component costs, unfavorable product mix, and suboptimal absorption of fixed operational costs. The lower-than-anticipated quarterly gross margin performance was largely due to higher-than-forecasted tariff expense arising from the combination of higher component costs and changes in geographic production as well as certain pricing and promotional activities. Fourth quarter 2021 operating expenses of $160 million declined by 15% and represented 35% of revenue. The decrease primarily reflected disciplined spending during the quarter across the board with the biggest drivers being adjustments to our working media and to a much lesser extend lower program spend on certain R&D projects in the fourth quarter of 2020. Our Q4 operating loss was $34 million. We had a tax benefit in the fourth quarter from adjustments to our full year tax rate driven by lower operating income combined with favorable FDII or in derived intangible income deduction. Our fourth quarter net loss per share was $1.05. From a full year perspective, 2021 revenue grew 9% to $1.565 billion. Geographically we generated 48% of our revenue in the US, which grew by 1%. International revenue grew by 18% highlighted by EMEA's 22% growth and Japan's 15% growth. 2021 gross margin of 35.3% declined nine percentage points from 2020. Two-thirds of the decline was split relatively evenly between tariffs and higher air and ocean transportation costs. The remainder was primarily attributable to product mix associated with shifts towards new products that have not yet achieved sufficient scale, higher component costs, increased warranty expense, and pricing and promotion. Full year operating expenses of $514 million grew by 6% due to the combination of higher personnel expenses associated with headcount, increased consulting to support certain R&D initiatives, and the investments associated with our DTC and marketing technology initiatives. Operating income in 2021 was $38 million and our operating margin was 2%. Our full year 2021 effective tax rate benefit was 0.4%. We reported 2021 EPS of $1.34. We ended 2021 with $235 million in cash and short-term investments a decline of $13 million from the end of Q3. The decrease primarily reflects our acquisition of Aeris, netted against our cash flow from operations in the fourth quarter. Fourth quarter DSOs were 32 days, an increase of one day from the same period one year ago. Our year-end inventory balance was $333 million or 92 days. In 2020, the year-end inventory was $182 million or 55 days. I'd like to spend a moment on this topic because the inventory balance is higher than historical norms. As I mentioned earlier, Q4 was particularly difficult due to both extended shipping time frames and supply constraints. Our year-end 2021 inventory balance and DII increase was primarily driven by a meaningful increase in in-transit inventory, which added 22 days to our DII. We also put our balance sheet to work as we carried higher inventory balances to maximize Q4 capacity utilization at our contract manufacturers and support end-of-life programs for certain products. Work is underway to optimize our inventory, although we expect inventory measured in dollars and days will stay elevated over the next couple of quarters. We believe improvement on this front in 2022 will be somewhat limited, due primarily to elongated shipping time frames. As a result we are targeting year-end 2022 DII levels in the low 70-day range. With that said, let's take a deeper dive into our 2022 outlook. As Colin noted, we anticipate 2022 revenue will grow in the range of 12% to 18% to $1.75 billion to $1.85 billion. We anticipate approximately 65% of our full year revenue coming in the second half, with an expected first half revenue decline of 3% to 8% and an anticipated second half growth of 26% to 34%. As we compare against a very unusual 2021, we expect 2022's first half, second half mix will resemble the way 2020 came together, when 67% of our revenue was generated in the second half. Overall, our 2022 revenue outlook assumes higher unit volume for robots, complemented by higher gross robot ASPs, along with $40-plus million from our newly acquired air purification products. We expect that between 70% and 75% of our air purifier revenue will come in the second half of the year following the completion of our rebranding work. As a reminder and we say this every year, we manage our business on a full year basis and encourage investors to focus on our annual targets. Since the timing of orders is challenging to forecast even under ideal conditions and large orders that shift from one quarter to the next can cause material fluctuations in our quarterly growth rates. Additionally, our revenue expectations contemplate yen and euro exchange rates roughly in line with current rates plus or minus 5%. We anticipate that our 2022 gross margin will improve modestly to between 36% and 37%. There are a lot of moving parts but at a high level, we expect that the combination of COGS productivity initiatives, decreased air freight and reductions in warranty expense will be partially offset by higher pricing and promotional activity and increased ocean transport costs. In terms of tariffs, we currently anticipate $42 million to $44 million in full year 2022 tariff costs. This is higher than our expectations in early December and it reflects our overarching focus on optimizing total landed costs across labor, materials, components and tariffs. As we finalized our 2022 commercial plans, product road maps and negotiations with our contract manufacturers in both China and Malaysia. We now expect that up to 75% of all Roomba robots produced for North America in 2022 will be made in Malaysia. As we expand the range of robots produced in Malaysia and increased overall volume in the second half of the year, we expect our tariff costs will decline as we exit 2022 and deliver meaningful savings in 2023. We are targeting 2022 operating costs in the range of $578 million to $621 million or approximately 33% to 34% of sales. The anticipated increase over 2021, primarily reflects higher personnel costs associated with planned new hires this year and returning incentive compensation to historical norms, increased working marketing and incremental spend on new R&D programs. While G&A and R&D are expected to trend near 2021 levels as a percentage of revenue, we anticipate sales and marketing will be slightly higher than 2021 as a percentage of revenue. This reflects working marketing returning to more historical levels to support our anticipated top line growth, the build-out of our MarTech stack and adding the talent necessary to operate it. Given our top line guidance and spending plans, we currently expect an operating profit margin of approximately 3%. In terms of other notable modeling assumptions for 2022, we anticipate other expense of around $2 million and an effective tax rate of approximately 3%. At these profitability levels relatively small dollar changes in pretax income along with the jurisdictional mix of those profits can cause meaningful changes in the effective tax rate. We anticipate a diluted share count of approximately 28 million shares. As a result, we expect our full year EPS to range from $1.50 to $2. One quick note on our GAAP EPS assumptions. We recently sold our stock in Matterport at the end of the lockup period. Due to the decline in the value of this investment since the end of 2021, we will recognize an approximately $17 million loss in our first quarter 2022, GAAP results as other income/loss. Overall, our strategic investment in Matterport delivered an outstanding return with a significant gain in our GAAP results over our initial investment. In terms of other 2022 financial guideposts, our business remains minimally capital intensive. Overall, we expect 2022 capital spending to be in the low to mid-$30 million range or approximately 2% of anticipated 2022 revenue. We anticipate that our cash flow from operations in 2022 will improve modestly from 2021 levels given our expected fundamental performance. In terms of some quick additional Q1 color, we currently anticipate Q1 revenue between $293 million and $313 million which would range from a 3% decline to 3% growth. We currently anticipate a Q1 margin in the low 30% range and tariff costs of approximately $8 million. We expect operating costs to range in the mid-40% range. As a result, we expect our operating loss will range from $37 million to $44 million. Our net loss per share for Q1 is anticipated to be between $1.35 and $1.60. In summary we managed through a very challenging second half of 2021 as component shortages hamstrung our ability to meet demand and made it difficult to absorb a range of higher-than-expected supply chain costs. Nevertheless, we delivered Q4 within our prior expectations and made important strategic progress during 2021 that we believe will help us further expand our business, drive profit improvement and fuel EPS growth in 2022 and beyond. That concludes my commentary. I'll now turn the call back to Colin for some additional color on the coming year.
