Roborock Q5+ iLifeV3s Pro Robot Eufy RoboVae 11S iRobot Roomba S9+ Samsung Jet Bot Al+
Roborock Q5+
Roborock’s midrange model overcomes most of the limitations of robot vacuums. It’s easy to clean, maps rooms flawlessly, and goes far on a charge. It doesn’t sense when its bin is full but can follow voice commands.

iLifeV3s Pro Robot
A budget alternative, this machine “outperformed much more expensive vacuums.” You control it with a remote, not an app. But it’s thorough, avoids obstacles, and has no brushes that would require regular cleaning to remove fur and hair.

Eufy RoboVac 11S
This budget option is “surprisingly thorough.” It cleans more randomly because it doesn’t map your space and it doesn’t empty its own bin. But it’s quieter than its smart rivals and “a great value for light everyday maintenance.”

iRobot Roomba S9+
Roomba’s top-end model can’t match the cleaning power of a traditional vacuum, but it has few robotic rivals on that score. Another plus: The bin is automatically emptied into a disposable bag in the docking station.

Samsung Jet Bot AI+
Though this pricey vacuum delivers “below average” cleaning performance, it’s good-looking, gentle on furniture, and is “packed full of features.” It can even double as a patrolling security camera that will live-stream to your phone.
