Best Robot Vacuum For Carpet: iRobot Roomba S9
Unfortunately, like most robot vacuums, many parts need to be cleaned or even replaced regularly, so recurring costs can add up over time. Still, if you’re looking for a feature-dense robot vacuum that can handle messes on carpeted floors, this is a good option, as it’s also one of the best vacuums for carpets that we’ve tested.
The iRobot Roomba S9 is the best robot vacuum cleaner for carpet that we’ve tested. This premium robot vacuum feels amazingly well-built, with high-grade plastic construction and dense wheels that enable it to roll smoothly on carpeted floors. Its vacuum head also automatically changes height depending on the surface it’s on, and there are three different suction power levels to choose from.
This vacuum delivers impressive performance on low-pile carpet and does a good job clearing various kinds of debris on high-pile carpet, though it might take an extra pass to clean larger debris like sand on this surface type. The vacuum’s vSLAM navigational system builds a virtual map of its coverage area, which you can access through its companion app to set up virtual boundary lines or schedule cleaning sessions for individual rooms. Its battery performance is also superb, as you can expect roughly anywhere between 50 to over 150 minutes of runtime on a single charge depending on your choice of settings and usage habits.
