About this item

Suction Grip Stability Control

This robot window cleaner is equipped with a 3800Pa suction system that maintains stable contact on vertical glass surfaces. A built-in uninterruptible power supply (UPS) provides up to 25 minutes of backup runtime during power interruptions. For added retention, the unit includes a 16.4 ft support rope. The internal suction system uses variable frequency control to regulate airflow, helping maintain consistent surface adherence during operation.

Cleaning With Measured Output

The unit features three selectable cleaning modes: Auto, Deep, and Manual. An integrated spray system releases a fine mist for controlled moisture distribution across glass surfaces. Cleaning is performed using reusable microfiber pads, and the unit comes with 6 additional replacement pads for extended use. An AI path planning system guides the robot in a structured cleaning pattern, while edge detection sensors identify borders and adjust movement to maintain contact. A remote control interface allows users to switch modes and manually direct the unit as needed.

Quick Pad Care

The device attaches directly to glass surfaces via suction and is operated using a remote control with clearly defined buttons for navigation and mode selection. Microfiber pads are removable and washable, allowing for repeated use and replacement using the included extra pads. The compact body measures 3.5 x 5.6 x 11.5 in, making it suitable for standard window panels. Its flat profile supports simple storage when not in use. For finishing, a dry pad can be used with the spray function turned off to complete a final pass.

My last robot window cleaner kept sliding down the glass and leaving streaks everywhere. This one sticks on solid, the suction is genuinely strong, and it moves in proper lines without losing its grip halfway through. Night and day difference.

It cleans in neat overlapping passes rather than random zigzags, so you can actually see it making progress. The spray keeps the glass damp enough that the pad picks everything up properly. Windows look genuinely clear when it finishes, not just smeared.

Very pleased with this. Works exactly as I hoped and makes a chore I used to dread completely effortless.

Fantastic little machine. It handles the whole window on its own and the results are consistently good. I use it every couple of weeks and it keeps the glass looking spotless.

The auto spray is genuinely handy. I wasn't sure I'd bother with it but it means I don't have to pre-wet the glass myself, it just handles that part on its own. Combined with the suction holding it firmly in place, the whole thing is pretty much hands-off.

I was worried the suction wouldn't hold on my older single-glazed windows since they're not perfectly smooth, but it handles them without any issue. The edge detection kicks in well before it reaches the frame and it reverses cleanly. Really impressed.

honestly i just use this thing without thinking about it anymore. slap it on, press go, done. it sprays the glass itself and figures out where the edges are so it doesn't go flying off. works exactly as it should.

the 3800pa suction is no joke. i've pressed on it while it's running just to test and it does not budge. climbs up the full height of my windows without any wobble. gives you a lot of confidence leaving it to run unsupervised.

What I noticed first is how well the edge detection works. It slows and turns before it reaches the frame every time, no bumping into the edges or getting stuck in corners. Feels like it actually knows what it's doing rather than just randomly bouncing around.

BRILLIANT!!

Really pleased with this. My windows haven't looked this clean in ages and I barely had to do anything.

Does what it says. Happy with it.

told my friend to get one of these after I got mine. she was worried it would just fall off the window and smash, but she's had it for a while now and says it's been totally fine. stays on even on her big patio doors.
