It would come as a surprise to more people than you think 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, though the Band-Aid level interchangeability really does exemplify just how iconic iRobot has become in the world of automated floor cleaners.
That can be attributed to the fact that iRobot 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 tracking the best Roombas isn't so chaotic when you consider that only a handful of those models are actually relevant at the time of your shopping.
How to tell the difference between the Roomba models
The arbitrary numbers and letters of the Roomba family tree are confusing at face value, but nothing that can't be told apart after learning a few super general classification themes.
When shopping for a Roomba, you'll really only be choosing from what I call iRobot's core lineup: the group of three to five Roomba series that are actively 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 692) or just words (like Roomba Vac or Essential).
As of fall 2024, the five main Roomba collections up for grabs are as follows, from most advanced to least advanced: Max, j series, s series (though nearly obsolete), i series, and Essential series.
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. Note that there are several Roombas that can be purchased with or without mopping capabilities or self-emptying docks. "Max" is a new layer of Roomba typology that was introduced with the drop of the Roomba Combo 10 Max — it refers to the ability of a mopping 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, and that means no smart mapping.
Do Roombas go on sale for Prime Day?
Yep, most Roombas will be on sale for Black Friday. And most Black Friday Roomba deals won't wait until actual Black Friday on Nov. 29 — we all know that Black Friday is more of a season nowadays than a day or even a week, and solid robot vacuum deals will be popping up throughout November. For instance, the mopping, smart mapping, and phone charger-avoiding Roomba Combo j5+ is already on sale for $399.99 — 45% off — during the first week of November. My fingers are also crossed to see the new Roomba Combo 10 Max beat its October Prime Day price and drop below $900.
Not sure which Roomba to eye on Black Friday? I've composed an exhaustive comparison guide to all of the best iRobot options below, including my experience with any of the models I've tested hands-on at home. Not every single Roomba model in existence will be listed in this guide, and not every "main" Roomba on iRobot's website will be recommended as one of the best. Rather, I've pulled Roombas from multiple price points that I think offer the best value in various categories that people care about, whether that's mopping, smart mapping, small obstacle detection, the cheapest possible path to all of those features, or budget alone. Each Roomba's battery life and automatic emptying capabilities will be noted, along with my reasoning for choosing the highlighted model over other Roombas with similar prices.
Here's your easy breakdown of all of the best Roomba vacuums as of fall 2024:
