The best budget robot vacuums
Today’s robot vacuums are becoming a bit like cars: with all the features, upgrades, and fancy trimmings available these days, it’s easy to forget that they can just be simple machines that get us from point A to point B. Yes, some bots blow hot air on their bums (mop pads) and deftly navigate dog poop, but there are plenty of basic budget robot vacuums that just do a decent job cleaning your floor autonomously — as long as you tidy up first.
While higher-priced, higher-powered robot vacuums clean better, budget bots do a perfectly good job, especially if you run them regularly. The biggest downside of cheaper models is they get stuck on cables, socks, shoelaces, and other paraphernalia you leave lying around. If you’re home and can untangle it, great, but if you’re not, then it will just sit there stuck until its battery dies, and you have to charge it up again before it will clean your floors.
Fancier models have obstacle recognition, and some even use AI to tell popcorn from poop and avoid the latter. If you want one of those, check out my Best Robot Vacuum buying guide. But if you think you can manage the task of picking up after yourself (and your puppy), a budget bot will save you a lot of money and still do a good job cleaning your floor.
Here’s a list of my favorite robot vacuums that don’t cost a fortune and will still get the job done.
You can pick up a brand new, two-year-old Roomba or Roborock with mapping and advanced navigation for half its original price. These gadgets should last for years, so it’s not like buying last season’s Prada slip-ons.
That said, sales are hard to keep track of, so some of the prices listed here may seem high for a budget bot. If you see one that fits your needs, keep an eye on The Verge’s deals page for when they go on an even better sale.
The cheaper the bot, the more important suction power is, as they tend to have fewer features that improve cleaning. Higher-end robots have things like better brushes, carpet boost mode, and dirt detection.
At a minimum, look for 2,500Pa (if the manufacturer lists suction power; some don’t). I also much prefer rubber roller brushes or a rubber/bristle hybrid over just bristle brushes. Rubber rollers get up more dirt and get tangled less than bristles.
Bear in mind that most budget mopping bots don’t really mop — it’s more just using a damp cloth to pick up the fine dust the robot’s vacuum left behind, which is useful but not essential. Mop attachments with water reservoirs also take up space on a robot and mean a smaller bin.
A big bin means you don’t need to empty it as often. Eight hundred milliliters is the largest I’ve seen, but anything over 450 ml is decent on a budget bot. With many bots now pulling double duty as mopping robots and the prevalence of auto-empty docks, it’s hard to find robots with big bins. But if you’re on a budget and don’t want to spend extra for the dock, a big bin will mean less hands-on time with your vacuum.
If you can swing it, I strongly recommend an auto-empty dock, and there are finally some cheaper versions out there. While it’s a nice-to-have rather than a must-have, delegating the chore of emptying the bin to the robot does mean your floors will be cleaner since a vacuum with a full bin won’t suck up dirt. Many standalone robots now have an auto-empty dock option you can add later if you want to wait and see, but buying them together is generally cheaper.
Few truly budget bots use the vSLAM (visual simultaneous localization and mapping) or lidar-powered navigation or mapping found on higher-end robots. Instead, the cheapest use the bump and roll technique, with more now adding a gyroscope function that at least makes them go in a straight line.
Choosing a newer Roomba or an older version of a high-end robot will get you this higher level of navigation, but I’ve also included a few bump-and-roll bots with basic mapping capability, which makes the experience better all around. Non-mapping bots may miss entire sections of your home and, when they start again after charging, may go over the area they last cleaned. However, mapping is less important if you want a bot for a single room or small apartment.
While most bots can recharge and resume (go back to their charging base and refuel before going back out again), a bot that can go for at least two hours on one charge will get the job done more quickly and be less annoying. I look for at least 120 minutes of runtime (180 is the best).
A lot of budget bots have barely usable apps; this is another reason why buying a lower-cost option from a company with higher-end models gets you a better experience, as the app is usually more polished.
A good basic app, though, should have the ability to set multiple schedules to send the robot out, an option for a do-not-disturb period (so it doesn’t start up again at 2AM because it finally recharged), and a way to link to voice assistants and smart home platforms like Amazon Alexa, Google Home, and Apple’s Siri.
Even at the budget end, you’ll be spending close to $200 on a robot vacuum, so repairability and the availability of replacement parts are a big bonus.
