If you have floor-to-ceiling windows, large glass sliders, or high-rise panes that feel impossible (and terrifying) to reach, you might want to invest in a robot window cleaner. (I also had no idea this was a thing!)

As of Aug. 14, you can get the Ecovacs Winbot W3 Omni Robot Window Cleaner for $594 at Amazon, down from $699.99. That's a 15% discount, or $105.99 in savings. This is also the lowest price we've tracked for this model.

This thing works exactly how you'd expect: It uses powerful suction and smart navigation to stick directly to vertical glass and wipe away dust, fingerprints, and smudges. Thanks to its TruEdge technology and WIN-SLAM 5.0 navigation, it scrubs deep into corners at 200 RPM and maps out an efficient cleaning path. Its wide-angle triple-nozzle spray system loosens stuck-on dirt before the wet pad wipes it clean, while 12 levels of anti-fall and suction protection keep it locked onto the window.

What really sets the W3 Omni apart, though, is its self-cleaning base station. Instead of forcing you to pull off gross pads mid-job, the station automatically rinses the wiping pads in just one minute so you can keep cleaning hands-free.
