WINBOT W2 PRO OMNI
3 independent reviewsRead the findings →Ecovacs's window robot tethered to a portable battery station, so you don't need a socket by every window. It's good on large windows and glass doors, and stays put safely. You'll still wipe the corners and move it between panes.

Feedback
What reviewers found
Three home tests, all positive. TechRadar called it one of the most impressive devices its reviewer had used, getting year-old grime off in one run. PCMag found it worked as advertised on a dozen windows, with faint streaks only on close inspection. EFTM found it cleaned weathered, dog-marked glass doors well and never slipped. TechRadar and PCMag both found the corners need finishing by hand, and PCMag had to rinse the pad between most windows.

Cleaning result
Mixed resultsThe glass itself comes up clean: TechRadar got year-old grime off in one run, EFTM cleaned weathered doors well, and PCMag saw only faint streaks up close. But TechRadar and PCMag both had to wipe the corners by hand.
Safety
Reviewers rate it highlyIt never fell in any test. TechRadar says it never lost suction, PCMag left it on the glass for ten minutes after finishing and it held firm, and EFTM never saw it slip.
Surfaces it suits
Mixed resultsFrameless glass is fine: PCMag used it on mirrors and a glass shower, and TechRadar on mirrors too. They differ on small panes, which TechRadar found it handled better than a rival, while PCMag thought it not worth using below a few feet across.
Ease of use
Reviewers rate it highlyTechRadar barely needed the manual, and PCMag found it easy even for people who avoid apps, with about 10 seconds to start it on a pane. EFTM liked not needing a socket. On outdoor glass, PCMag rinsed the pad between most windows.
Noise
Mixed resultsIt's moderate rather than quiet. TechRadar called it relatively quiet but found the fan sometimes drowned out the spoken prompts, and PCMag measured about 61dB at six feet and could hear it from upstairs.
Value
Reviewers rate it highlyBoth judged the premium price justified. TechRadar says it offers a lot for the money, and PCMag notes few robots clean windows this well and it could save money if you pay for window cleaning.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Gets even filthy glass clean
TechRadar tested it on windows that hadn't been washed in over a year and got them spotless in one cleaning cycle, using only a little solution and a damp cloth. EFTM found it cleaned its weather-beaten, dog-smeared glass doors well in a single deep pass. PCMag was impressed that it left no significant marks, though it spotted faint streaks on close inspection, and said it did better than most people could in the same time.
Corners and pads still need you
Both TechRadar and PCMag found the corners are its weak spot. TechRadar explains why: a round sensor in each corner of the robot keeps the cloth from reaching right in. PCMag had to wipe dirt out of exterior corners with a rag. Pads get dirty fast outdoors, and PCMag rinsed and refitted the pad between most windows. Keep a spare pad and a cloth to hand.
The battery station is the point
Every tester liked not needing a socket. PCMag found the claimed 110 minutes accurate while moving between windows, and valued being able to run it plugged in when a socket was near, which the older W2 OMNI can't do. EFTM cleaned both sides of three large glass doors with over half the battery left. The station doubles as storage, though PCMag puts it at around 18 pounds, so carrying it about is real work.
It stayed put in every test
None of the three reviewers saw it fall. That's a good result from three homes, not a promise that it never will. Follow ECOVACS’ instructions for the safety tether, station placement and anchoring every time they apply, and make sure you can reach the robot safely to attach it and take it off. For upstairs outside panes, think about whether you can get to them from inside before you start.
Choose your glass carefully
PCMag warns against textured glass, static-cling stickers and panes with gaps between them, since anything uneven can break the seal. It also found it wasn't worth using on anything smaller than a few feet across. On the plus side, its frameless-edge sensing worked well: PCMag used it on mirrors and a glass shower without a fall, and TechRadar found it coped with panes too small for a full turn better than a rival HOBOT.
This page covers the W2 PRO OMNI, not the W2 OMNI or the newer W2S models. EFTM tested in Australia and PCMag in the US.
Our take
Should you buy the WINBOT W2 PRO OMNI?
Best for: Large panes or glass partitions needing regular upkeep. Skip it if: You do not want to rinse pads or finish corners by hand.
Consider it for large windows and glass doors that you can safely reach to attach and retrieve the robot. It reduces manual wiping, but you must move it between panes and set up the tether and station correctly. The W2S OMNI adds edge scrubbers, while the W3 OMNI adds pad washing at the station; compare those features with the current prices.
The W2 PRO OMNI is Ecovacs's battery-station window robot from late 2024, an update of the W2 OMNI. The robot is tethered to a box that holds a battery, stores everything and reels the cable in and out, so you don't need a socket by every window. The Pro adds a stronger spray, a zone-cleaning mode and the ability to keep working while the station is plugged in. The newer W2S models add spinning edge scrubbers.
TechRadar, EFTM and PCMag all reported effective glass cleaning, though PCMag could still see faint streaks up close. Corners needed manual wiping, and PCMag rinsed the pad between most outdoor windows. PCMag reported a station weight of about 18lb, or 8.2kg, so moving the equipment between windows is a consideration. Check ECOVACS’ surface restrictions before using it on textured glass or panes with gaps.
Before you buy
The questions people ask about this one
Does it work on frameless glass?
Yes. Ecovacs lists framed and frameless glass, per the specifications, and TechRadar explains that sensors in each corner spot the edge of a frameless pane. PCMag used it on a frameless glass shower and big mirrors, and it never ran off or fell.
What happens if the power cuts out?
Ecovacs says it stays attached for over 30 minutes after power loss, per the specifications. The combined cable doubles as a safety line, the heavy station is meant to act as an anchor, and there's a separate tether. TechRadar and EFTM had no falls in testing.
Does it leave streaks or miss the corners?
TechRadar reported a streak-free finish, while PCMag could see faint streaks up close. Both found the cloth missed the very corners, so expect to finish those by hand. How it turns out also depends on how dirty the glass is and how clean the pad is.
How long does one window take?
ECOVACS quotes about 1 minute 45 seconds per square metre in fast mode. On top of that you'll be moving the robot, rinsing the pad and wiping the corners. Deep-clean modes are slower, so the whole job can take a good deal longer than that fast-mode figure suggests.
Which cleaning fluid should I use?
Use the solution and dilution ECOVACS specifies for this model; a bottle comes in the box. The manual explains how to fill the tank and prepare the pad. If you want to use a different cleaner, check it's compatible first.
Alternatives
Other window-cleaning robots to compare.
WINBOT W2S OMNI
Why consider it: Three recent tests found it cleans everyday dirt well and gets closer to the edges than most.
The compromise: Corners still aren't perfect, and you move it between panes and wash the pad yourself.
C1 Station
Why consider it: Its portable station also means no socket hunting, and testers found it good on regularly cleaned glass.
The compromise: It's heavy, fairly loud and won't shift stubborn marks.
S7 Pro
Why consider it: TechRadar found it excellent on lightly dirty glass and accurate at spotting frameless edges.
The compromise: It runs from the mains only, and both of its reviewers saw streaks on dirtier glass.

Head to head
ECOVACS WINBOT W2S OMNI vs WINBOT W2 PRO OMNI
Our verdict: The W2S OMNI is the newer model and adds spinning edge scrubbers, which testers found get closer to the frame, though corners still aren't perfect. Both use a battery station and need the pad rinsing. The W2 PRO OMNI makes sense mainly if you find it noticeably cheaper.
