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 winter 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.
To pinpoint which Roombas have smart mapping, pay close attention to how navigation is discussed in the title or in the list. If you don’t literally see the words “Smart Mapping” anywhere, that Roomba cannot map your home and clean specific rooms on command. No, “Smart Navigation” or anything about cleaning in “neat rows” does not count.
When is a new Roomba coming out?
Probably not at least until spring 2025, but that probably won’t even be the new flagship Roomba.
iRobot is on a different release schedule than most other big robot vacuum brands that typically debut their new flagship models for the year at the Consumer Electronics Show (CES) every January. Obviously, the Roomba family is spread out across a range of prices, and iRobot has quietly unveiled the more basic Roombas earlier than the big, new Roomba in the past. But if, in your eyes, a question about “the new Roomba” refers to the next Roomba that’ll be a big deal, that probably won’t be seen until August or September 2025. The past two flagship Roombas (the Combo j9+ and Combo 10 Max) both dropped in late summer (in 2023 and 2024, respectively), so the fanciest Roomba in this list now will probably be the fanciest Roomba for a while.
This doesn’t mean exciting things don’t happen to the Roombas already out. Roombas go on sale pretty frequently, even if it’s not the Black Friday, holiday, or Prime Day season. So it’s possible that at any point in time you’re reading this, the particular Roomba you’re eyeing is $100 or two off. I list the MSRP for each by default, but will mention the most common sale price that each Roomba drops to in “The Good” section.)
Not sure which Roomba would be the most worth it in your household? I’ve tested nearly every Roomba series released since 2019 in my own home, and have composed a running Roomba model comparison guide to all of the best iRobot options at any point in the year. 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 December 2024:
How we tested
As a senior shopping reporter, I have been testing popular robot vacuums for Mashable in the various apartments I’ve lived in since 2019. My hands-on analyses span from budget models under $200 that just cover the basics to $1,500 (or more) premium models that are the market’s most advanced in the way they clean, navigate my home, and take care of their own recurring maintenance.
So far in 2024, I’ve had hands-on experience with the Roborock Qrevo Master, Roborock S8 MaxV Ultra, Eufy X10 Pro Omni, Shark Matrix RV2300, Shark Detect Pro, Shark Matrix Plus 2-in-1, Roomba Combo j9+, Roomba Combo j5+, Narwal Freo X Ultra, Dyson 360 Vis Nav and Yeedi M12 Pro+. I am also currently working with the Roomba Combo 10 Max + AutoWash Dock and Shark PowerDetect 2-in-1 with neverTouch Pro Base.
My own personal three-bedroom apartment — not a lab — makes up the testing grounds for every robot vacuum, where a combination of hardwood floors, tile floors, and rugs of various piles are tackled. Over the course of at least four weeks, each robot vacuum is put through a series of standardized tests that flow into a scoring rubric that I’ve created to exemplify all factors of owning a robot vacuum and trusting it on a daily basis. That rubric is made up of four pillars:
-
Cleaning thoroughness: I’m pickier than average about what it takes for a floor to feel “clean,” and I’m trusting these robot vacuums in my own home — and pitting them against my trusty Dyson. To encapsulate the full spectrum of debris a robot vacuum might encounter, each robot vacuum and its suction power settings complete an obstacle course of standardized tests for multiple types of debris on both hard floors and rugs, an efficiency score being given to each. The robot vacuum and mop combos also complete three additional scrubbing tests on hardwood and tile. As for the actual “dirty” status of those floors being tackled, each robot vac is sent over both fresh messes (like crumbs, drinks, and sauces I spill purposefully) and more lived-in messes that build up over time (like dried or sticky splatters, shoe prints near the door, dust bunnies in corners, and matted-down cat hair on the rug).
-
Navigation: I consider a robot vacuum’s ability to maneuver to the right spot in the first place as a litmus test ahead of getting into any nitty gritty cleaning capabilities. In my testing, each vac’s navigational brainpower is analyzed by its smart mapping accuracy and ability to find specific rooms and zones for spot cleaning, as well as its ability to swerve safely around walls or between chair or table legs. Robot vacuums that can successfully detect phone chargers, pet waste, and laundry with small obstacle avoidance technology are given an extra star.
-
User-friendliness and politeness as a house guest: The ideal robot vacuum will be a relatively seamless addition to your household, and blend in nearly as easily as any other appliance used daily would. If a robot vacuum is loud, clunky, or generally a pain to use, you’re not going to want it in your house at all — so things like noise level, battery life, size, aesthetic design, and the intuitiveness of using the app can make or break the experience.
-
Maintenance: Some robot vacuums are more automated than others when it comes to how they take care of themselves past the actual cleaning. If someone is already considering the robot vacuum route because of the hands-off cleaning experience, they might want that convenience to extend to dustbin emptying or mopping pad cleaning, too, which would get them off the hook from maintenance for days or weeks at a time.
Finally, I can’t not consider the overall bang for your buck for each robot vacuum. Are its features on paper and actual cleaning competence worth the price tag, and how practical is that cost for the average household?
