The Ecovacs Winbot W3 Omni is a premium window robot designed to take the effort out of window maintenance.
New to Ecovacs’ Winbot range, the Winbot W3 Omni features a dock that washes the wiping pads between runs. I’ve been using it for a couple of weeks, and it’s turned out to be an impressive robot.
At $1299, it’s not exactly cheap and it’s very much a one-trick machine, but for big windows or frequent maintenance due to salt air or pollution, it’s a massive upgrade over a bottle of Windex.
Overall Rating: 4.5 / 5

Price: $1299 | For households with large panes, floor-to-ceiling glass, and tough outdoor conditions
Setup & First Impressions
The W3 Omni feels substantial from the moment you unpack it. Included in the package as reviewed was the robot, the washing station, the battery pack, cleaning solution, and two mop pads.
Assembly and setup took about ten minutes including a firmware update. Setting up and configuring the unit is fairly straightforward, using the robot itself and the Ecovacs Home companion app.
The robot features a 5.5-metre long cable that lets you clean wide windows and rows without moving the base station between panes.
Its build quality feels good, with nice materials, satisfying tactile buttons, and flush-fit panels.
Design & Aesthetics
The Omni station looks like a miniature washing machine. It features an inbuilt carry handle for transport, and a hanger to store the robot when it’s not in use.
It uses a motorised reel to wind in the robot’s power cable and a storage cabinet on the rear to tuck away the charging cable and safety cord.
The Winbot W3 Omni features separate clean water and dirty water tanks that it uses for rinsing the wiping pads before and after a window cleaning run.
Life With the Ecovacs Winbot W3 Omni
I’ve been testing the Winbot W3 Omni for a few weeks, and I’ve settled into using it whenever the glass starts looking a bit grimy. I’ve tested it on most of the glass around my apartment, including windows, sliding glass doors, bathroom mirrors, floor-length wardrobe mirrors, balcony glass, and shower glass.
During a run, it heads to the top of the glass pane, and works its way down in horizontal passes, spraying detergent in front of itself on each swipe. To finish, it scrubs along the edge of the glass with its corner feet.
Positives
The results were excellent. I thought I could do a good job of the glass by hand, but the robot surpassed my efforts with a single button press.
It delivers excellent coverage, following edges and corners precisely, leaving almost no gaps.
After a couple of runs, I trusted the robot enough to enjoy watching it on the glass rather than worrying about it falling off. It’s very secure once stuck on, and I felt I may damage the glass before I was able to pull it off.
Negatives
The most noticeable issue I ran into was the residue left behind at the end of a cleaning pass. The Winbot W3 Omni leaves behind a faint outline of where the pad is, and for a polished look you must manually wipe it with a microfibre cloth.
With some window designs, the Winbot W3 Omni thinks it’s stuck, and demands you manually drive it around the glass. However, after restarting the cycle on the same pane it does not get stuck the second time.
It can legitimately get stuck on panes with roller blinds, but this only happened once during my testing, and not consistently with every time I used the robot on that pane.
Shower glass with a bit of soap residue on it presented a problem on the first pass where the robot appeared to slide down the glass further than it meant to. Heavily soiled glass requires multiple passes with the Heavy Duty mode for this reason.
Performance & Reliability
The Winbot W3 Omni delivered consistent, clear results on every glass type I used it on. Its obstacle handling was impressive when it comes to avoiding handles on glass doors or sliding windows.
Soiled shower glass may take an extra run, but the robot eventually leaves these panes clear and streak free.
I got the best results from cleaning the wiping pad before and after each pane of glass. Because the package comes with two pads, you can rinse one pad while the robot is using the other to clean.
Before a clean, you can choose from different modes depending on your needs. Fast Clean is best for light, quick passes like touchups on relatively clean indoor glass. Deep Clean and Thorough Clean use a little more detergent to produce a thorough clean, and this is what I used most.
Heavy-Duty Clean is best for heavily soiled glass. Edge Clean and Spot Clean are best for targeting particular areas, while Zone Clean helps deal with larger single panes.
Practical Considerations
The robot’s long cable allows it to clean large windows up to 8 metres wide by 2.5 metres tall in a single run. Zone Clean may provide a workaround for larger panes.
The robot performs best on larger, square panes. Irregular shapes, curved glass, and uneven surfaces with cracks may cause insufficient air pressure and compromise the robot’s safety.
In terms of safety features, the Winbot W3 Omni has multiple layers of technology and safety to prevent it from falling.
It suctions onto the glass with strong force, and can stay stuck as long as the battery lasts. In the case of a power issue, it can stay on for around 30 minutes.
The station itself also grips the floor with its suction foot, and is heavy enough that I doubt it would be pulled over.
As a last resort, the safety cord is rated to 100 kilograms and can be wrapped around an anchor point for those times you want to be absolutely certain nothing will fall.
Noise levels during a cleaning run are about the same as a vacuum cleaner set to high suction. Because of the way it operates, you shouldn’t leave it entirely unattended anyway, but it’s loud enough to disturb others in the home temporarily.
Value & Alternatives
At its RRP of $1299, the Winbot W3 Omni is positioned on the premium end of the robot window cleaner market. The extra money buys you flexible window handling, robust safety credentials, and automatic pad washing.
If you’ve only got a few standard windows, a cheaper option like the W2 Omni or W1 Pro may do the trick, but for homes with a lot of glass, awkward heights, or tricky exterior panes, the W3 Omni earns its price tag.
Would I Buy It With My Own Money?
Yes, if I was regularly dealing with glass cleaning. This is a single-purpose robot that’s great at its job, and makes window maintenance a breeze. If you’re in a position where window cleaning is a tedious chore, the Winbot W3 Omni can be a big help.
