🏆 Best deal right now
Half price at $399.99, down from $799.99, and currently $70 cheaper than two models below it in the range.
Shop the Deals →iRobot’s current promotion is narrow but genuinely deep. Only two robots in the Roomba lineup are reduced, and one of them is half price. The rest of the range, right up to the $1,299.99 flagship, sits at full list.
That concentration creates an oddity worth knowing about, because the discounted Plus 405 Combo now costs less than two models positioned beneath it. Everything below is priced from iRobot’s own deals page, along with the standing perks that apply whether or not something is on sale. The company puts a firm end date on this promotion rather than letting it roll.
Active iRobot deals, August 2026
Half off, and the standout of the current sale by some distance. This is a combo robot, so it vacuums and mops, and the AutoWash dock cleans the mop pad for you rather than just emptying debris. At $399.99 it is the cheapest way into iRobot’s Plus tier and it undercuts two cheaper models in the range, which is covered in the card below.
Vacuum only, no mopping, with a dock that empties the bin for you. At $279.99 it is the cheapest robot iRobot currently sells and a sensible pick if you have hard floors you do not need mopped or carpet throughout.
iRobot’s Refer and Earn programme gives a friend 15% off a robot and pays you a credit when they purchase. If someone in your household or circle is also shopping, running both purchases through the referral is worth more than any code currently circulating.
Signing up to iRobot’s email list takes 10% off a first purchase. On a full price robot that is worth considerably more than it sounds, though it will not stack with the sale prices above.
Robot vacuums are consumable heavy, and brushes, filters and mop pads all need replacing. iRobot is running up to 20% off select accessories with a build your own bundle option, which is the right time to stock up if you already own a robot.
iRobot offers Affirm financing with rates starting at 0% APR subject to approval. The 105 Vac works out from around $24 a month and the Plus 405 Combo from around $34, which spreads a robot vacuum across a year without adding cost if you qualify for the 0% tier.
This is the quirk worth acting on. At its sale price the Plus 405 Combo is $399.99, while the Roomba 105 Combo and the Roomba 205 DustCompactor both sit at $469.99 undiscounted. So the higher tier robot with the mop washing AutoWash dock is currently $70 cheaper than two models beneath it. Unless you specifically want the DustCompactor, the 405 is the better buy at today’s prices.
iRobot puts an explicit end date on the current promotion rather than running an open ended sale, and the page states offers are valid while the current promotion runs. That is an ongoing promotion rather than a fixed-deadline event, so if the 405 at half price is what you want, it is worth not sitting on it.
Across the current Roomba lineup only two products carry a reduced price. The Max 705 Combo at $1,299.99, the Plus 505 Combo at $999.99, the Max 705 Vac at $899.99, the 205 DustCompactor at $469.99 and the 105 Combo at $469.99 are all at list. So the sale is narrow, and the value is concentrated entirely in the two models above.
The top of the vacuum only range at $899.99. Listed here for comparison rather than as a deal, since it is at full price. Worth seeing against the $279.99 105 Vac to judge whether the jump is worth it for your floors.
The step up from the discounted 405 within the same Plus tier, at $999.99 full price. Given the 405 is currently $399.99, the gap between them is $600 right now rather than the usual $200.
The flagship combo at $1,299.99 and not part of the current promotion. If budget is the deciding factor, the discounted 405 does the same two jobs of vacuuming and washing its own mop pad for less than a third of the price.

How to get the best iRobot price
1
Start from the deals page rather than the category pages, since only two robots are actually reduced.
2
Compare the sale price against the models below it, because right now the discounted 405 undercuts two cheaper robots.
3
Sign up to email first if you are buying at full price, for 10% off a first purchase.
4
Use the referral programme if anyone you know is also buying, since 15% off their robot plus your credit beats most codes.
5
Add accessories in the same order while the up to 20% accessory offer is running.
💡 Decide between vacuum only and a combo before comparing prices. A combo with an AutoWash dock washes its own mop pad, which is the feature that actually saves you work.
About iRobot
iRobot makes the Roomba, the robot vacuum that effectively created the category, along with combo models that vacuum and mop in a single pass. The current range splits into vacuum only robots and combos, paired with either an AutoEmpty dock that empties debris or an AutoWash dock that also cleans the mop pad.
Naming follows a tier system. The 105 and 205 sit at entry level, Plus models like the 405 and 505 sit in the middle, and Max models such as the 705 sit at the top. Higher numbers mean more capability, though as the current sale shows, they do not always mean a higher price.
iRobot vs the competition
A quick look at how iRobot compares with two other robot vacuum brands on the things that affect what you pay.
| iRobot ★ | Shark | Roborock |
|---|
| Entry price on sale | $279.99 | Comparable | Comparable |
| Self washing mop dock | Yes, AutoWash | Some models | Yes |
| Discount style | Dated promotions | Frequent sales | Frequent sales |
| Financing | Affirm from 0% APR | Varies | Varies |
💡 Our take: iRobot discounts less often than its rivals, so when a model goes half price it is worth taking seriously rather than waiting for a better one.
Best months to buy a Roomba
JanFebMarAprMayJunJul 🔥AugSepOctNov 🔥Dec 🔥
- July (🔥): Prime Day season, which is when the current dated promotion is running.
- November (🔥): Black Friday, historically the deepest discounting of the year on robot vacuums.
- December (🔥): the gifting run, when bundles and accessory offers are pushed hardest.
💡 Robot vacuums follow the electronics calendar rather than the seasons, so the summer and late autumn events are where the real reductions sit.
Stack your savings
🔥
Check the tier above before you buy
A discounted higher tier robot can undercut a cheaper one, which is exactly what the Plus 405 is doing at $399.99.
🤝
Use the referral if you can
15% off a friend’s robot plus a credit for you is worth more than any code currently circulating.
✓
Buy consumables in the same order
Brushes, filters and mop pads all wear out, and the accessory offer runs up to 20% off.
💡 The email signup discount applies to a first purchase and will not stack on top of the sale prices, so it is most useful on a full price model.
iRobot deal FAQ
Does iRobot have a promo code?›
iRobot discounts through dated promotions on its own deals page rather than public codes, and only a small number of codes are ever verified. The dependable savings are the 10% email signup offer for new customers and the referral programme worth 15% off a friend’s robot.
What is the best Roomba deal right now?›
The Roomba Plus 405 Combo with AutoWash dock at $399.99, down from $799.99. That is half off and a $400 saving, the deepest discount in the current lineup.
Why is the Plus 405 cheaper than the 105 and 205?›
Because it is the only model discounted that heavily. At $399.99 the Plus 405 Combo sits below the Roomba 105 Combo and the Roomba 205 DustCompactor, which are both $469.99 at full price. It is a temporary consequence of the promotion rather than the normal order of the range.
When do the current iRobot offers end?›
iRobot states the offers are valid while the current promotion runs. Unlike a rolling countdown banner, there is no specific published end date right now, so the prices on this page should be treated as time limited.
What is the difference between AutoEmpty and AutoWash?›
An AutoEmpty dock empties the robot’s debris bin for you. An AutoWash dock does that and also washes the mop pad, which matters on combo models because a dirty pad is the main reason mopping robots stop working well.
Does iRobot offer financing?›
Yes, through Affirm, with rates starting at 0% APR subject to approval. iRobot quotes roughly $24 a month on the 105 Vac and $34 a month on the Plus 405 Combo.
The Bottom Line
This is a small sale with one genuinely excellent price in it. The Roomba Plus 405 Combo at $399.99 is half off, saves $400, and comes with the AutoWash dock that washes the mop pad rather than merely emptying the bin. If you want a robot that vacuums and mops without much intervention, that is the one to buy.
The detail that makes it a clear decision is that at $399.99 it costs $70 less than both the Roomba 105 Combo and the 205 DustCompactor, which are still at $469.99. Buying up the range is cheaper than buying down it this week. iRobot has not published a fixed end date on these prices, so it is not a promotion to think about for long.
