Roombas are more practically priced now than they have been in years. And that’s before discounts — during Prime Big Deal Days, many 2025 Roombas are already up to 44% off at Amazon for Prime Big Deal Days, making this a great year to invest.
October Prime Day (officially starting Tuesday, Oct. 7) is now the second Prime event we’ve experienced after iRobot’s epiphany in March 2025. For years before that, Roombas were simply way too expensive for their own good. The other top robot vacuums out there were offering the same features, like smart mapping and small obstacle avoidance, at much lower prices. But that all changed when iRobot released a fleet of new Roombas that kept those same core robot vacuum features at more realistic prices.

But we still love to see them get even cheaper during an Amazon sale event. You can squeeze so much more out of a few hundred bucks when Roomba shopping now than you could a few years ago. Back in the day, the sale price for a mopping Roomba that could self-wash its mopping pads was $999 — now, that kind of mopping Roomba is less than $500. There’s even a Roomba with smart mapping on sale for $149.99 that wasn’t present during Prime Day in July. The old cheap Roombas didn’t do much more than bump around aimlessly, and they barely ever dipped below $200. With this intel in mind, feel free to rule out any i Series or Essential Series Roombas — they’re not bangs for your buck like the others in this list.
I’m keeping track of the best Roomba deals at Amazon for Prime Big Deal Days below. But for comparison’s sake, skim over my guide on how to choose a robot vacuum, then take a peek at the other great Prime Big Deal Days robot vacuum deals that I’m eyeing.

Why we like it
I wasn’t sold on the idea of getting a Roomba as your budget-friendly robot vacuum until this year. The older entry-level Roombas, like the Roomba 694 and Essential series, completely skipped smart mapping — a feature that can make or break your robot vacuum experience. But now, several budget Roombas under $200 can remember a map of your home and clean specific rooms or zones on command. I’m highlighting the Roomba 104 Combo here, which is nearly identical to the Roomba Combo 105 that I tested at home.

The Roomba 104 sweeps with 7,000 Pa of suction power, which is actually a quite commendable number compared to the 5,500 Pa seen on many cheap Roborock models. Not only is this a robot vacuum and mop combo, but its smart mapping capabilities help it to recognize carpet and keep it dry when mopping.
Up until the latest round of Roombas that hit the scene in spring 2025, I’d often actively advise against getting a Roomba. They didn’t even have smart mapping, whereas the entry-level Shark robot vacuums did — often at a lower price point than the cheap Roombas. But after testing the new base-tier Roomba 105, I can finally give iRobot credit for actually putting effort into a cheap Roomba. The Roomba 104 Combo featured here is nearly identical to the 105, but also mops.
