It might come as a surprise that „roomba“ isn’t the universal term for a robot vacuum. It is, in fact, a capital „R“ that denotes Roomba as a proper noun rather than a generic trademark. Roombas are just robot vacuums made by iRobot, and looking for the best Roombas is a much more specific task than looking for the best robot vacuums in general. However, Roomba’s Band-Aid or Kleenex level fame really does prove just how iconic iRobot has become in the world of automated floor cleaners.
There’s a good reason for that: Not only was iRobot first to the robot vacuum party, but the company has consistently delivered some of the most reliable robot vacuum models for two decades. More than 20 Roombas have come out since the first one hit homes in 2002, but if you’re looking for the best Roomba today, there are only a handful of models you need to know in 2025.
iRobot randomly released a ton of new Roombas this spring
iRobot released four new Roomba series in March 2025, deviating from its (unofficial) summer release schedule. I think iRobot had two reasons to hurry: the spring release of the top robot vacuums from CES and the company’s rocky financial situation. As someone who tests robot vacuums for a living, I’ll be the first to tell you that Roombas were flopping in a sea of smarter, more fairly-priced robot vacs from the likes of Roborock and Shark.
The new Roomba 105, Roomba 205, Roomba Plus 405, and Roomba Plus 505 series are further broken down into eight total models, many with completely different physical designs that don’t scream „classic Roomba.“
iRobot is playing catch-up with its competition, and for the first time, you can buy Roombas that use LiDAR for smart mapping, Roombas with dual spinning mopping pads, and a Roomba that compacts its own dust rather than self-emptying. Despite such innovations, the new 2025 Roombas are surprisingly affordable, especially compared to debut prices of past Roombas.
With all of these new Roombas thickening the plot, the same old question remains: „Which Roomba is the best?“ I’ve tested nearly every Roomba released since 2019, and I’m regularly updating this guide as I test the 2025 models at home. After comparing suction, pet hair pickup, mopping, smart mapping, small obstacle detection, and price, I chose the Roombas that offer the best value for different types of households.
How to tell the difference between the Roomba models
The iRobot Roomba 105. The Roomba Combo i5+. The Roomba Combo j7+ (not to be confused with the Roomba j7). The arbitrary numbers and letters of the Roomba family tree are confusing at face value, but we can teach you.
When shopping for a Roomba, you’ll choose from what I call iRobot’s core lineup: the group of three to five Roomba series sold on iRobot’s website. Any Roomba whose title includes a letter and a number (like j9+ or i5) or the word Max is more advanced than a Roomba with just numbers in the title (like 105, 205, or 692) or just words (like Roomba Vac or Essential).
A plus sign (like j9+) denotes that the model comes with a self-emptying dock, and Roombas that mop will have „Combo“ in the title. „Max“ is a new Roomba term introduced with the Roomba Combo 10 Max — it refers to the ability of a hybrid Roomba to wash and dry its own mopping pad within the self-empty dock. On the other end of the spectrum, „Essential“ means „most basic“ in the Roomba family, meaning no smart mapping.
Other Roombas I’ve tested
I’ve tested several Roombas that are no longer main players in the Roomba guide for 2025. The Roomba Combo j9+ doesn’t wash or dry its mopping pad, and is simply too expensive to be worth buying over its siblings like the Roomba Combo 10 Max, Roomba Plus 505. or Roomba Max 705. Plus, the j9’s increasing obsoleteness has pretty much halted its ability to get a noteworthy discount nowadays.
I have also removed any 600 series Roombas from this guide for a similar reason: They just can’t compete with the newer cheap Roombas that have stronger suction and smart mapping. When I tested the Roomba 694, it pissed me off more than it impressed. The Roomba 694 and Roomba 692 are hard to find in stock, anyway, and it’s rarely for less than the Roomba 105 (my new top pick for the best cheap Roomba).
