If you don't have time to regularly sweep or vacuum, robot vacuums are an easy way to make sure your home stays clean without you needing to do all the work. Since they use various types of technology like lasers or cameras to navigate and maneuver around a room, they can generally avoid furniture and get beneath couches and tables with relative ease. Some even automatically empty their dirt compartments, which further reduces the work you need to do. Although they aren't as good at cleaning carpet as more traditional upright vacuums, many of them come with smart pathing technology to clean more efficiently. Many of them also come with companion apps or remote controls so you can set up scheduled cleaning times or place boundaries to keep it out of certain areas.

We've tested over 25 robot vacuums, and below are our recommendations for the best robot vacuums you can buy. These picks are selected not only based on their performance but also their feature set, design, and price. For more recommendations, take a look at our list of the best vacuums, the best vacuums for high-pile carpet, and the best vacuums for pet hair.


  1. Best Robot Vacuum For Bare Floors: Roborock S6

    The best robot vacuum for bare floors that we've tested is the Roborock S6. This very well-built model delivers an outstanding performance on bare surfaces like hardwood and linoleum, where it easily clears pet hair and most debris like sand and cereal. It even comes with a mop attachment meant for wiping up sticky messes and spills, although we don't test it currently.

    Its battery performance is fantastic, as even if you use the most powerful suction mode, it provides just under two hours of continuous cleaning time. When set to its least powerful 'Silent' mode, battery performance stretches to more than three hours. There are several useful automation features available through a companion app, like the ability to set virtual boundary markers and cleaning schedules for different rooms.

    Unfortunately, its performance on carpet is just okay since it struggles to clear debris like sand and baking soda, especially from high-pile carpets. It also has several parts that need to be removed and serviced regularly, and some that have to be replaced periodically. That said, if you're looking for a hands-off way to keep bare floors clean, it's a great option.

  2. Cheaper Alternative: Roborock E4

    Vacuum Type
    Robot
    Bagless
    Yes
    Cordless
    Yes
    Anti-Allergy Filter (HEPA)
    Yes

    If you're looking for a hands-off way to keep your floors clean but want something cheaper, you may prefer the Roborock E4. Its navigation system isn't as advanced as the Roborock S6, so it's not as good at maneuvering itself, but it's quite a bit less expensive and has a similarly remarkable performance on bare floors. It feels impressively well-built and has a slightly bigger dirt compartment. Depending on what power setting is used, the battery provides roughly two to three hours of continuous cleaning time, which is fantastic. While it doesn't have a smart-pathing feature like the S6, it cleans in an organized S-shaped pattern and produces a map of the area it covered that you can see in the companion app. Unfortunately, you can't set virtual boundaries for this vacuum or create cleaning schedules for individual rooms.

    Go for the S6 if you want the vacuum with the most advanced navigation features, but consider the E4 instead if performance is your priority and you'd rather spend less.

  3. Best Robot Vacuum For Carpet: iRobot Roomba S9

    Bare Floor
    7.6
    Low-Pile Carpet
    7.3
    High-Pile Carpet
    8.8
    Pets
    5.8

    Yes
    Cordless
    Yes
    Anti-Allergy Filter (HEPA)
    Yes

    The iRobot Roomba S9 is the best robot vacuum cleaner for carpet that we've tested. This very well-built model delivers great performance on low-pile carpet and does a good job of sucking up debris on high-pile carpet. Thanks to its smoothly-rolling wheels, it maneuvers effectively on shaggy surfaces without getting stuck, while its automatic surface-adjustment feature allows it to seamlessly adapt to different floor types.

    It's very well-built, with a high-grade plastic construction that feels quite premium. It uses an advanced navigation system to create a permanent virtual map of its cleaning area. This allows it to develop increasingly battery-efficient cleaning routes, which helps it achieve a continuous battery life of almost an hour, even when run continuously on its highest power setting. You can use its companion app to schedule cleaning times for individual rooms or set up virtual boundary markers for places you don't want it to clean.

    Unfortunately, it has quite a few parts that require regular maintenance or replacement, as its brushroll, side brush, and allergen-trapping HEPA filter need to be replaced regularly, which are recurring costs that can add up over time. It's also a little heavy and lacks a carrying handle, so carrying it to another area can be a bit of a hassle. Overall, however, it's a great choice if you're looking for a robot vacuum that can easily handle carpeted floors.

  4. Best Budget Robot Vacuum: Yeedi K650

    Cordless
    Yes
    Anti-Allergy Filter (HEPA)
    No

    The best robot vacuum in the budget category that we've tested is the Yeedi K650. This affordable model has an outstanding performance on bare floors, where it easily clears pet hair and debris. It can maneuver on carpets and does a good job of picking up debris like sand from that surface type.

    The battery performance is fantastic, as it provides roughly one to four hours of continuous cleaning time, depending on what power setting is used. This vacuum has a larger dirt compartment than most robot models we've tested, and its performance stays quite consistent as it fills up, so you can empty it a little less often. There are a few automation features available through the companion app, like the ability to create a cleaning schedule and have the vacuum return to its dock.

    Unfortunately, it struggles a bit to clear pet hair and fine debris, like baking soda, from carpets. Also, it cleans in a random pattern and sometimes misses a spot or bumps into obstacles. That said, it's fairly good at maneuvering itself overall, and if you're looking for a budget-friendly robot vacuum, it's a great choice.

Notable Mentions

  • Roborock S5: The Roborock S5 is very similar to the Roborock S6 since it has a mopping feature, but it doesn't come with disposable mopping cloths. The S6's performance on each surface type is also better. See our review
  • Neato Botvac D7: The Neato Botvac D7 is a premium robot vacuum that delivers fantastic performance on bare floors, but it doesn't clear quite as much debris on low or high-pile carpet as the iRobot Roomba S9. See our review
  • bObsweep Bob Pro: The bObsweep Bob Pro is a budget-friendly robot vacuum with good overall build quality and great cleaning performance on bare floors, but it struggles significantly with pet hair and doesn't do as well on carpets compared to the eufy RoboVac 11S. See our review
  • eufy RoboVac 11S: The eufy RoboVac 11S is a budget robot vacuum that has a better performance than the Yeedi K650 on low-pile carpets, but it's not as good on bare floors or high-pile carpets. The Yeedi also has a longer battery life and better automation features, but the eufy comes with a remote control, so it's a good alternative if you want to be able to use your robot vacuum without an internet connection.
