We have floor-to-ceiling windows that collect pollen like crazy. ClearVista's suction never once fell off, even in the corners I could never reach safely, and it cleans about 90% as good as a human.

Sensors trace window edges first, then overlap interior passes so corners get scrubbed instead of skipped, unlike random zigzag robots.
A 150 kg-rated tether, 20-minute backup battery, and instant alert system guard against every failure mode, even mid-cycle power loss.

Steer, pause, or redirect from across the room while LED lights show battery, suction, and cycle progress in real time.
50 Newtons of downward force plus rotating pads lift caked-on grime and mineral marks that spray-and-wipe methods leave behind.

Your free gift: Microfiber Cloth SetFREEClearVista is a robotic window cleaner built for upper-floor and hard-to-reach glass, using sensors to trace each pane's edges first before plotting overlapping interior passes so corners get scrubbed instead of skipped the way random zigzag patterns do. Dual rotating microfiber pads apply 50 Newtons of force under 5600 Pa suction to lift caked-on grime, bird droppings, and hard water marks that a spray-and-wipe routine leaves behind.
Safety is layered rather than relying on suction alone: a 150 kg-rated tether anchors the unit to the glass, a 20-minute backup battery holds suction if main power drops mid-cycle, and onboard sensors halt the motor and lock the tether the instant they detect an obstruction. Setup needs no tools, just tying off the tether and pressing start, with the whole unit running at 40 to 60 decibels, quieter than normal conversation.
