The 2024 model that Tom's Guide raved about for streak-free floor-to-ceiling windows. How-To Geek and Reviewed liked the cleaning too, but found missed corners, lost suction on gapped panes, and too niche a use for the price.
Top complaints
- Lost suction on gapped panes
Reviewed found it lost suction, stopped and threw an error about ten feet up on floor-to-ceiling panes with gaps (it did not fall). How-To Geek says surfaces must be mostly square, without cracks or protruding sections, or suction can break.
Source: Reviewed, How-To Geek review - Debris left in corners and edges
How-To Geek found some debris left in corners and along edges that needed a quick wipe by hand. Reviewed, by contrast, saw full coverage to the frame.
Source: How-To Geek review, Reviewed - Pricey and niche; moving it is tedious
How-To Geek calls it pricey for potentially limited uses with a less compelling app. Reviewed calls it too niche for an overall recommendation and says reattaching it pane by pane is simple but tedious.

What owners love
- Streak-free results
Tom's Guide went from pollen-tinted to perfectly streak-free floor-to-ceiling windows in minutes. How-To Geek found no streaking on a mirror door, and Reviewed says it removed all hard-water stains (grease needed a second run).
- Minimal setup
Tom's Guide says you dampen the pad, add water, place it and turn it on; it confirms by voice when secured. Reviewed says it runs on three buttons.
Source: Tom's Guide, Reviewed - Firm grip, portable station
How-To Geek says suction never failed in its testing and praises the battery base station and 18-foot cord. Reviewed notes a motorized tether that reels back in.

What experts say
- Tom's Guide: Hands-on (2024-06-23, $599 list): streak-free results with less water than a squeegee, though you still move it between windows yourself.
- How-To Geek: 7/10 (2024-04-16, $599.99): impressive cleaning and suction, but can't handle some glass designs, is pricey for limited uses, and the app is less compelling.
- Reviewed: Too niche for an overall recommendation (2024-06-18); good for homes with several tall, hard-to-reach windows. About 63 dBA.
