Much like Roombas and other automated products, entry-level robotic window cleaners aimlessly wander around your window, cleaning as they go until they’re told to stop. Some varieties use a piece of magnetic metal on one side with an array of magnets on the other - but either way, the basic principle is the same. ![]() On the flip side, this connection type is more prone to failure, and that’s why vacuum cleaners typically use a tether or safety cord.Īs the name implies, magnetic models use two magnets to cling to windows - one on the underside of the unit and one on the top. These versions have a stellar convenience factor as you don’t need to access both sides of the window to attach the robot. In a vacuum model, the device’s motor generates suction that is used to hold the machine in place as it washes the glass. ![]() Make sure you have a long enough extension cord for your home or else you’ll run into the same issue as a cleaner with a dead battery.Ī robotic window washer needs a stable way to attach to its cleaning surface, and there are two main methods on the market today - vacuums and magnets. In some ways, that can be worse than a completely dirty window.Ĭorded models needn’t worry about battery life, but they’re less practical as they must be physically attached to an outlet. Otherwise, they’ll leave the job half-done, which can result in unsightly marks and streaks on your glass. These units generally cost more, and they need to hold a charge long enough to completely finish the job. There is a tradeoff to battery power, though. battery poweredīattery-powered electronics offer exceptional convenience, and window-washing robots are no different. A high-level benchmark speed is 4.7 inches per second (1 square meter per 2.4 minutes), but if pace is less important to you, lower speed ratings may save you some money. A substantial unit will obviously cover a 48-inch by 48-inch window in fewer passes than a smaller one, but keep in mind that movement speed can vary with motor and track types. Size and weight should be high on your priority list when shopping for robotic window cleaners, as different units are rated for windows of different sizes and thicknesses. It depends on the depth of the tile joints and the roughness of the tiles - too bumpy and the robot will not maintain suction well. ![]() Although they’re best suited for windows, vacuum robotic cleaners can clean bathroom tiles quite well.
