WINBOT W2 PRO OMNI
Ecovacs' window robot with a battery station you carry from pane to pane. Three testers found it cleans even grimy glass well and never fell, but the corners still need a wipe and you'll rinse the pad often.
The short version
The W2 PRO OMNI is Ecovacs' 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 version adds a stronger spray, slightly quicker routes, a zone-cleaning mode and, most usefully, the ability to keep working while the station is plugged in. It has since been followed by the W2S models, which add spinning edge scrubbers.
The trade-off is that it's help, not a hands-off job. You still lift it onto each pane, and outdoor glass can need the pad rinsing after every window or two. Round sensors in its corners stop the cloth reaching right into the window corners. It needs flat, unbroken glass of at least 30 by 40cm, so small panes, textured glass and panels with gaps are out.
Our take: Buy it if you have big windows, glass doors or a glass balcony and you'd happily move a robot from pane to pane rather than climb a ladder. It's worth it mainly where you can find it cheaper than its newer siblings. If you want better edges, the WINBOT W2S OMNI adds spinning scrubbers. If rinsing pads is the chore you hate, the W3 OMNI's station washes them for you.

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.

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 testers had it fall. TechRadar says it never lost suction, and the heavy station plus a tether should anchor it if it does. PCMag left it on the glass for ten minutes after it finished and it stayed firmly attached. EFTM reminds you to clip on the safety tether for upstairs windows, in case the battery runs out mid-clean.
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.

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 edges?
Streaks are faint at worst: TechRadar got spotless glass and PCMag only saw faint streaks up close. Corners are the real gap. TechRadar found its corner sensors keep the cloth out of the very corners, and PCMag wiped exterior corners by hand.
How long does one window take?
PCMag timed about two minutes for a fast clean of a four-by-eight-foot pane, with deep cleaning taking about four times as long. Ecovacs quotes 1 minute 45 seconds per square metre in fast mode, per the specifications. Add time to rinse the pad.

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.
WINBOT W2S OMNI
Three recent tests found it cleans everyday dirt well and gets closer to the edges than most.
Corners still aren't perfect, and you move it between panes and wash the pad yourself.
C1 Station
Its portable station also means no socket hunting, and testers found it good on regularly cleaned glass.
It's heavy, fairly loud and won't shift stubborn marks.
S7 Pro
TechRadar found it excellent on lightly dirty glass and accurate at spotting frameless edges.
It runs from the mains only, and both of its reviewers saw streaks on dirtier glass.
