Window and other robots

A window robot climbs glass with suction and wipes it while you stay off the ladder. It is a maintenance tool: owners say it handles dust and rain spots well, needs pre-cleaned glass for grime, and still needs you to move it between windows. This hub also links our home humanoid and office robot guides.

Best window robot for most people

Ecovacs Winbot W2S Omni

$407.55 at ecovacs.com, seen Oct 29, 2026In stock on ecovacs.com. A bundle with extra accessories is $440.55.

Our pick. The W2S Omni climbs glass with suction, sprays from three nozzles and lowers a spinning edge scrubber near the frame, and Ecovacs says it gets within about 1 cm of the edge. Its station holds a battery for 110 minutes of cordless cleaning, winds the cable and anchors the safety rope (company claims). Owners say it does a very good job on dusty, rain-spotted glass but still leaves a little dirt in the corners.

Best under $200

HOBOT-298

$199 at hobot.us, seen Oct 29, 2026In stock on hobot.us; list price $249.

The budget pick. The HOBOT-298 is a square, corded window robot with an ultrasonic mist sprayer and a 40 ml tank, and HOBOT says it cleans about 40 square meters per tank (company claim). At $199 (list $249) it costs half as much as the Winbot. It has no cordless mode and no cable station, and owners say it is loud and works best on glass that is already fairly clean.

Best square-body alternative

HOBOT-2S

$299 at hobot.us, seen Oct 29, 2026In stock on hobot.us; list price $349.

The HOBOT-2S adds a second ultrasonic sprayer, edge sensors and app control to the 298 for $299 (list $349). HOBOT says the square body reaches further into corners than round pads (company claim). Owner reviews are rough, though: many Australian buyers report streaks, getting stuck under handles and poor support from a local distributor. Consider it only if you will pre-clean the glass and want the square shape.
