Keep reading to learn about some of the key considerations when choosing a Roomba, and see our hands-on evaluation results later in this article. Most Roomba models are of a disk shape, measuring 338–353 millimetres (13.3–13.9 in) in diameter and 86–94 millimetres (3.4–3.7 in) high depending on the model. The S9 and S9+ robots are D-shaped rather than circular, with the flat part of the D at the front, and are narrower at 311 millimetres (12.2 in) wide. A large contact-sensing mechanical bumper is mounted on the front half of all models, with an omnidirectional infrared sensor at its top front center.
Their “everyday” prices are a bit high, but we’ve seen some pretty good deals on the version of the Shark that comes with a self-emptying dock. Since we know that laser-nav bots are all fairly similar to one another, this Shark model bissell crosswave cordless could be a good choice if you see it on sale. Wyze is known for selling good-enough and implausibly affordable smart-home gear such as security cameras, locks, and thermostats, in addition to the laser-nav Wyze Robot Vacuum.
Some models will even feature an automated higher suction setting for deep cleaning carpets. To pick up pet hair, you need a robot vacuum with strong suction power. Most companies in this space advertise power in pascals , the metric unit of pressure, though iRobot doesn’t always make this information easy to find. In general, the more power, the better, especially if you have carpet, but battery life and obstacle avoidance capabilities are also important factors. Some robot vacuums, including versions of our pick, the iRobot Roomba i3+ EVO, and our also-great pick, the Roborock Q5+, are self-emptying (or auto-emptying). They each come with a big charging dock that sucks debris out of the robot through a trapdoor in the dustbin and stores the debris in a disposable bag or a bagless bin .
Those who want their Roomba to cover more square footage may prefer a model with a longer battery life, or perhaps two robots to cover different zones or floors. When compared to the other robot vacuums, its performance was lackluster and did not earn an award in our guide. Through testing, we found that it didn’t do a great job getting stubborn flour “dust” out of crevices between floorboards , and it tended to not grab our “crumbs” of rice very well. As there are other models with more suction power on the market, consider skipping this base model for an upgraded option.
The Shark IQ Robot XL also stands out for its self-cleaning brushroll, which in our testing successfully prevented hair from getting wrapped around it, a common problem with many robot vacuums. Moreover, it delivered strong suction power, effectively cleaning dust, debris, and pet hair from hard flooring and carpet, and it never got stuck. It offers a number of useful smart features, including home mapping for targeted room cleaning and virtual no-go zones. The Eufy RoboVac 11S and other Eufy bots whose model names begin with a number instead of a letter stand out as some of the quietest robot vacuums we’ve tested. They’re also some of the shortest, so they can fit beneath more pieces of furniture. Like the Roomba 694, the Eufy 11S is semi-random in its navigation, so it’s best for cleaning just a few rooms at a time.
Bots rarely miss patches or waste time recleaning areas that they’ve already visited. If their batteries run low before they can finish cleaning an entire level of a home, they’re smart enough to drive back to their dock, recharge for a few hours, and then pick up where they left off. Based on our testing, the Eufy RoboVac X8 seemed to be a fine laser-nav robot vacuum, but it’s relatively expensive and doesn’t offer meaningful improvements over the company’s cheaper models. Its defining feature is supposed to be its strong suction, with two turbines pulling 2,000 pascals each (whereas most laser-nav bots have a single turbine and less than 2,500 pascals of suction total).
