Robot vacuums have been scooting around our living rooms and sucking up dust for years now. But robot mops have had a few kinks to work out—most notably, after a few deep cleans of your kitchen, you’ll have to tidy up the robot mop yourself. The Narwal T10 ($549) takes its hygiene into its own hands with a self-cleaning charging station, where it washes and dries its own mopping pads with a refillable water tank. By swapping out the pads, you can also use the Narwal as a vacuum, though you’ll have to map the space’s layout on the device’s companion app if you want to keep it off the carpet. —Patrick Lucas Austin
