The list of Roombas on sale at Amazon ahead of Prime Day 2025 looks much different than the list of Roombas on sale during Amazon’s Big Spring Sale in March. And that’s a very, very good thing.

This is because Amazon Prime Day 2025 is the first big sale event for most of the new Roombas that debuted in March (they were far too new to get any real discounts during Amazon’s spring sale). And these 2025 Roombas are unlike any Roombas we’ve seen before.

iRobot finally read the room and saw that other top robot vacuums from the likes of Shark and Roborock had better features for less money. The newest Roomba vacuums are the company’s most practically priced and feature packed in years. The most affordable base-tier model can finally clean specific rooms on command instead of just bump around. Multiple new premium Roombas switched to spinning mopping pads that wash and dry themselves — without costing $1,000.

The newfound cost efficiency renders old iRobot models like the Roomba i3 or Roomba Essential Y0140 worthless. Amazon is essentially ignoring their existence in the weeks preceding Prime Day, instead shaving between 30% and 54% off the new Roombas for the first time. I’m already tracking all of the worthwhile early Prime Day Roomba deals below, as well as tracking all of Amazon’s other early Prime Day robot vacuum deals.

Note: Any deal marked with a 🔥 has dropped to a record-low price at Amazon.

Why we like it

Up until the latest round of Roombas that hit the scene in spring 2025, I’d often actively advise against getting a Roomba as your budget-friendly robot vacuum. The older, entry-level Roombas, like the Roomba 694 and Essential series, 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.

The Roomba 104’s 7,000 Pa of suction power not only destroys the mediocre suction power of past cheap Roomba vacuums like the Roomba i5, but is actually quite a high number for the price range at all. During testing in my apartment, the 105 barely missed any kitty litter, random crumbs, or surface-level pieces of hair or fur balls. It swept along edges and corners much closer than the other basic Roombas. With this improved cleaning combined with a self-empty dock, this is the most well-rounded Roomba that has ever dropped below $250.
