🏆 Best deal right now
Down from $319.99, the deepest cut iRobot is running and the cheapest way into a Roomba that mops. Seven Roomba robots are reduced right now, from 13% to 47% off, and the offers expire on September 12.
Shop the Deals →iRobot’s September promotion is wider than the one it replaced. Seven Roomba robots carry a reduced price you can actually buy, from 13% off the Plus 575 Combo up to 47% off the 105 Combo, and the Electro Plus floor cleaner is cut too. Three models are sold out, including two that still display a discount, and the rest of the range sits at full list.
Seven Roomba robots are reduced, spanning the entry 105 range up to the Max 775 Combo, with discounts running from 13% to 47%. Everything below is priced from iRobot’s own deals page, along with the standing perks that apply whether or not something is on sale. One caution: iRobot still shows $200 off the Max 705 Vac, but that product is out of stock and can’t be added to a basket, so treat it as unavailable rather than as a deal.
Active iRobot deals, October 2026
iRobot runs a trade-in program against a new Roomba or Braava. Its own numbers disagree with each other: the rotating site banner says up to $150, while the trade-in page itself says up to $195. You ship the old robot with a prepaid label, iRobot verifies the model, and the credit lands against the original order. It’s separate from the sale pricing on this page, so check whether the two combine before you buy. A trade-in stacked on the $200 off the Max 775 Combo would be the largest total saving available here.
Roomba 105 Vac Robot with AutoEmpty Dock drops to $249.99 from $449.99, 44% off and a saving of $200. 1 variant was still in stock at this price when we checked.
The Roomba 105 Combo Robot drops to $169.99 from $319.99, 47% off and a saving of $150, which is the deepest cut iRobot has running and the cheapest way into a Roomba that also mops. Note the name carefully: the 105 Combo with the AutoEmpty Dock is a different product, and that one has gone back to $469.99 flat with no discount at all.
Roomba Plus 415 Combo Robot with AutoWash Dock drops to $499.99 from $599.99, 17% off and a saving of $100. 1 variant was still in stock at this price when we checked.
Roomba Plus 515 Combo Robot with AutoWash Dock drops to $599.99 from $699.99, 14% off and a saving of $100. 1 variant was still in stock at this price when we checked.
Roomba Plus 575 Combo Robot with AutoWash Dock drops to $699.99 from $799.99, 13% off and a saving of $100. 1 variant was still in stock at this price when we checked.
iRobot’s Refer and Earn program 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's worth considerably more than it sounds, though it won't stack with the sale prices above.
Robot vacuums are consumable heavy, and brushes, filters and mop pads all need replacing. iRobot has swapped its old select-items discount for a flat code: SAVE15 takes 15% off every accessory, printed on iRobot’s own accessories page. Less headline than the up-to-20% it replaced, but it applies to the whole catalog rather than a short list, which usually works out better. It expires with the rest of the September offers on September 12, 2026.
iRobot offers Affirm financing with rates starting at 0% APR subject to approval. At its sale price the 105 Vac works out from around $23 a month, which spreads a robot vacuum across a year without adding cost if you qualify for the 0% tier.
Worth knowing before you go looking for it. The Roomba Max 705 Vac still shows $249.99 down from $449.99 on its product page, the same $200 saving as the 105 Vac, but it’s out of stock and there’s no way to add it to a basket. The Plus 405 Combo and the Plus 505 Combo are both sold out too, at $799.99 each with no discount. The closest in-stock equivalent to the Max 705 Vac is the Max 715 Vac at $599.99, down from $699.99.
iRobot puts an explicit end date on this promotion rather than running an open-ended sale: its deals page reads offers valid until 09.12.26. Every price on this page was checked against that page and matches. That leaves a single day from this update, so if one of these is the robot you want, don’t sit on it. The August round of these prices expired on 08.22.26 and came back at slightly different numbers a few weeks later, which is the pattern to expect if you miss this one.
Seven Roomba robots carry a reduced price you can actually buy today, running from 13% off on the Plus 575 Combo up to 47% off on the 105 Combo, plus the Electro Plus hard floor cleaner at $329.99 from $399.99. Three models are marked down or listed but sold out: the Max 705 Vac, the Max 705 Combo and the Plus 405 Combo. The rest of the range sits at list, including the Plus 678 Combo at $899.99, the Max 875 Combo at $1,199.99, the Combo 10 Max at $1,399.99, the 205 DustCompactor at $469.99 and the 105 Combo with AutoEmpty Dock at $469.99.
The vacuum-only pick a step above the entry model, down to $599.99 from $699.99. It replaces the Max 705 Vac, which shows the same kind of discount but is out of stock. Worth seeing against the $249.99 105 Vac to judge whether the jump is worth it for your floors.
iRobot is calling this one a first: $200 off the Max 775 Combo, down to $799.99 from $999.99. It ties the 105 Vac for the biggest dollar saving on the site, and unlike the Plus 405 and Plus 505 Combos, which are both sold out at $799.99 with no discount, this one is in stock. The AutoWash dock washes the mop pad rather than just emptying debris.
The odd one out on this list, because it isn’t a robot. The Electro Plus is a corded 5-in-1 hard floor cleaner that washes and disinfects rather than roaming on its own, down to $329.99 from $399.99. Useful if your floors are mostly tile or hardwood and you want a deeper clean than a mopping robot manages, and it’s the only non-robot in iRobot’s September promotion.

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
Check stock before you get attached to a price. Three models on iRobot’s own site display prices you can’t act on.
3
Sign up to email first if you're buying at full price, for 10% off a first purchase.
4
Use the referral program 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 507 sit in the middle, and Max models such as the 707 sit at the top. Higher numbers mean more capability, and with seven models discounted at once the ordering by price can shuffle, so compare sale prices rather than tier numbers.
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's 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.

Check the tier above before you buy
A discounted higher tier robot can undercut a cheaper one, so compare sale prices across tiers rather than assuming the lower number is cheaper.
🤝
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 won't stack on top of the sale prices, so it's 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 program worth 15% off a friend’s robot.
What is the best Roomba deal right now?›
By percentage, the Roomba 105 Combo Robot at $169.99 from $319.99, which is 47% off. By dollars it’s a tie at $200: the 105 Vac with AutoEmpty Dock at $249.99 from $449.99, and the Max 775 Combo with AutoWash Dock at $799.99 from $999.99.
Which advertised iRobot deals can’t actually be bought?›
Three of them. The Roomba Max 705 Vac still shows $249.99 down from $449.99 but is out of stock, and the Plus 405 Combo and Plus 505 Combo both sit at $799.99 with no add-to-cart option. The nearest equivalents you can actually buy are the Max 715 Vac at $599.99 from $699.99 and the Max 775 Combo at $799.99 from $999.99.
When do the current iRobot offers end?›
iRobot publishes a date on its deals page: offers valid until 09.12.26. Every price here was checked against that page on September 11 and matches, so the window is down to about a day. When the August round expired on 08.22.26, the prices came back a few weeks later at slightly different numbers, which is the pattern to expect.
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 $23 a month on the discounted 105 Vac and around $25 on the 105 Combo.
The Bottom Line
Seven Roomba models are reduced, and which one to buy depends on whether you care about the percentage or the amount. The deepest cut is the 105 Combo Robot at $169.99 from $319.99, 47% off, but it has no dock. The largest saving is a tie at $200, between the 105 Vac with AutoEmpty Dock at $249.99 and the Max 775 Combo with AutoWash Dock at $799.99. For most homes the sweet spot is the Plus 415 Combo at $499.99 from $599.99, which vacuums, mops and washes its own pad.
The detail worth acting on is stock rather than price. Three models still display prices you can’t act on: the Max 705 Vac at $249.99 from $449.99, and the Plus 405 and Plus 505 Combos at $799.99, all listed as unavailable. Of the seven you can actually buy at a discount, the Plus 415 Combo at $499.99 is the best balance of price and capability. iRobot has published an end date of 09.12.26 on these prices, so this isn't a promotion to think about for long.
