FAQ

Skylight Cleaning Robots, Explained

What is a skylight cleaning robot?

A skylight cleaning robot is a compact, automated device that drives across glass skylights, roof windows and glass roofs to scrub and squeegee them dry. Most models attach with a powerful vacuum motor and a safety tether, so they can work on sloped and overhead glass without you climbing a ladder.

Are skylight cleaning robots safe on all types of glass?

Most robots work on standard tempered and laminated skylight glass, but you should always check the manufacturer's guidance for cracked or fragile panes, textured glass and special coatings. Every review on this site notes the glass types and roof pitches a model is rated for.

Do I still need to use a safety tether?

Yes. Even robots with strong vacuum suction should be used with the included safety tether when cleaning overhead or high glass, as a backup against sudden power loss or suction failure. Safety performance is one of the key factors in our rankings.
