All robot window cleaners. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Ecovacs Winbot W2 Omni | Ecovacs Winbot W3 Omni |
|---|---|---|
| Window style | ||
| Standard residential | GoodFlat, smooth glass with minimal framing works optimally. Edge detection excels on standard rectangular windows. | GoodWIN-SLAM 5.0 edge detection optimized for standard framed glass panes. |
| Large panes (8 ft+) | DependsLarge single-pane windows may exceed dock suction radius or require mid-session repositioning on expansive home layouts. | DependsEdge detection may struggle with frameless or oversized panes; test coverage on sample window. |
| Specialty / textured | PoorFrosted, textured, tinted, curved, or decorative glass confuses optical sensors; edge detection fails and manual override required. | PoorHeavy tint, coatings, and specialty glass compromise edge-detection sensor reliability. |
| Frame style | ||
| Frameless / minimalthey differ | GoodFrameless glass presents edge-detection advantages; optical sensors identify perimeter clearly without frame interference. | PoorEdge detection requires framed boundary; frameless glass lacks reference structure for autonomous pathing. |
| Standard mullions | GoodStandard framed windows with aluminium or vinyl trim work well; dock-based edge mapping adapts to frame geometry. | GoodStandard aluminum or vinyl frames suit WIN-SLAM 5.0 calibration and tether management. |
| Heavy bezels | DependsHeavy or ornate framing may interfere with edge-detection calibration or require manual sensor repositioning between cleaning cycles. | DependsOrnate or steel-frame windows may interfere with edge-detection sensor path; manual path tuning recommended. |
| Building height | ||
| Single-story | GoodGround-floor windows align with dock placement in garage or utility room. Wall-mounting and suction-hose reach optimized for single-story deployment. | GoodTether range optimized for ground-floor and patio window coverage without ladders. |
| 2 – 3 storiesthey differ | DependsTwo-story homes possible with dock on upper level, but long hose runs (>5m) may reduce suction pressure and increase runtime drain. | GoodSecond-story windows accessible via tether from ground-level dock; roof anchor point or balcony ledge may extend reach. |
| 4+ stories | PoorSafety rope limited to 5-meter length; high-rise and multi-story buildings exceed rope capacity and create unacceptable fall risk. | PoorTether length and safety constraints cap reach below third-story exterior windows; manual access required. |
| Power preference | ||
| Corded OK | GoodDock operates on standard 120V or 240V outlet depending on region. Corded power enables continuous dock pad-washing without battery drain. | GoodRobot operates on dock-powered water and electrical supply; corded operation is the only mode available. |
| Cordless preferredthey differ | DependsRobot is cordless but dock requires AC power for pad drying and water-pump operation. Dock must be wired; full cordless operation not possible. | PoorProduct is not cordless; auto-clean dock requires mains power and water supply connection. |
| No preference | GoodDock-based architecture requires AC wall outlet, but robot operates cordless during cleaning sessions for up to 35 minutes per charge. | GoodRobot is corded and dock-dependent; consider this when evaluating power and water placement options. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
What the score is built from.
Nine inputs across three pillars, each weighted as shown and each scored so more is better. A robot can lead on one and trail on another, which is the point of showing them apart.

What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Ecovacs Winbot W2 Omni
The portable station needs no installation and travels to the work, and it is also the anchor the fall-protection system loads, so where it is set down matters as much as where the robot goes.
Optocoupler edge sensing with a 0.2 second response gives fast, systematic coverage on flat glass, and it assumes a flat plane; curved and heavily textured surfaces sit outside it.
Washable pads at $29.99 for two keep running costs low, and they are washed and dried by hand between sessions.
Ecovacs Winbot W3 Omni
The composite safety cable and 1 m backup rope tie the robot to a station that travels with it; every window means moving the station rather than reaching out from a fixed point.
Vortex Wash cleans the pad contact-free in about a minute, with wastewater going to a sealed tray; the 80 ml tank and the station’s 10 kg still move window to window with the work.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Ecovacs Winbot W2 Omni
- Panes the owner cannot reach to mount the robot on
- The robot is lifted onto the glass by hand and taken off the same way. An exterior face that cannot be reached from an open window or a balcony is out of scope regardless of what the machine does once it is on the pane.
- Curved glass and heavily textured surfaces
- Ecovacs makes no claim for either, and both work against a suction seal and edge sensing that assume a flat plane. Floor-to-ceiling, small, frameless and tilting windows are inside the stated scope.
- Households with few windows or infrequent cleaning
- The purchase is the cost, not the upkeep: the mopping pads are washable and Ecovacs sells them at $29.99 for two, shared across the W2 series. A small pane count is where the machine has least to do.
- Smart-home-first setups with voice-control requirements
- Control is the station panel or the app. No HomeKit, Alexa or Google Home integration is documented for this model.
- Owners needing fully hands-off operation
- The robot is placed on each pane by hand and taken off by hand, and the station is carried to wherever the work is. Between panes, a person is doing the moving.
Ecovacs Winbot W3 Omni
- High-rise apartments with exterior-only upper-floor windows
- The station sits indoors at the window being cleaned, with the robot inside the reach of its 1 m rope. Panes that can only be worked from the outside leave nowhere to put it. Ecovacs specifies no roof fixture, wall mount, or owner-selected anchor point for this machine.
- Homes with exclusively frameless or specialty glass
- Frameless glass and certain coatings complicate edge detection. Heavy aluminum or ornate frames may interfere with automatic pathing calibration.
- Owners expecting a whole house cleaned without returning to the machine
- The station holds 80 ml of water and prompts when it runs dry, and it moves to whichever window is being cleaned rather than serving the house from one position. Multi-window sessions mean repeated refills and repositioning by the owner.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Ecovacs Winbot W2 Omni
- After every use: Take the pads off, wash them by hand and let them dry fully before storing them.
- Weekly: Wipe the suction inlet and the edge sensor windows, and run the compound cable through your hand to check for abrasion.
- Monthly: Inspect the safety rope inside the compound cable and its attachment points, and clear dust and grit from the station’s cable take-up.
- Seasonally: Replace the mopping pads when the fabric no longer holds water evenly. Ecovacs sells washable pads for the W2 series at $29.99 for two; no change interval is published.
- As needed: Wipe the station body and storage compartment dry, and reseat the robot in the compartment so the cable coils cleanly.
Ecovacs Winbot W3 Omni
- Weekly: Inspect the composite safety rope and power cable for twists, kinks, or debris; 2-3 minutes.
- Monthly: Clean dock inlet filter and suction port; descale if hard water present (~5-10 minutes).
- Every 3-6 months: Replace cleaning pads (~$20-30 per pair, roughly $60-100 in consumables annually).
- Every 3-6 months: Check the 1 m rope at the station base for wear. It is fixed to the station rather than owner-rigged, so there is nothing to retension; a frayed rope or a damaged cable is a service item, not a field repair.
- Before each session: Fill the station’s 80 ml water tank and empty the wastewater tray.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
