Leave the elbow grease to the Limodo Window Wizard Smart Window Cleaning Robot. This clever robot uses a powerful suction system to attach to your glass windows and doors. Armed with smart sensors, the Window Wizard works effortlessly to scrub away smudges and dirt. It can even determine its own path and detect edges to ensure efficiency with every clean. Using both an app and remote control, you can also dictate where you’d like the Window Wizard to clean. Under the sleek exterior, the Window Wizard works diligently on even the grimiest of surfaces. It gets its power from the cord or relies on its 30-minute backup battery if an outlet isn’t nearby. Impressively, the Window Wizard does all of this while producing low noise.
