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 | HOBOT S7 Pro | Ecovacs Winbot W3 Omni |
|---|---|---|
| Window style | ||
| Standard residential | GoodDesigned for standard horizontal-sliding and framed windows up to 86 inches; edge detection aligns with frame geometry. | GoodWIN-SLAM 5.0 edge detection optimized for standard framed glass panes. |
| Large panes (8 ft+) | DependsLarger panes work but edge sensor coverage may miss frameless corners; manual repositioning may be needed. | DependsEdge detection may struggle with frameless or oversized panes; test coverage on sample window. |
| Specialty / textured | PoorSpecialty glass (skylights, curved, skylights) and frameless designs exceed auto-pathing capability and edge-detection scope. | PoorHeavy tint, coatings, and specialty glass compromise edge-detection sensor reliability. |
| Frame style | ||
| Frameless / minimal | PoorEdge detection and auto-pathing depend on frame geometry; frameless windows have no reference edges for navigation. | PoorEdge detection requires framed boundary; frameless glass lacks reference structure for autonomous pathing. |
| Standard mullions | GoodStandard aluminum or vinyl framed windows are the design target; edge sensor performance is predictable and reliable. | GoodStandard aluminum or vinyl frames suit WIN-SLAM 5.0 calibration and tether management. |
| Heavy bezels | DependsHeavy frames (steel, wood) are acceptable but may interfere with edge sensor readings near frame edges; test before full sessions. | DependsOrnate or steel-frame windows may interfere with edge-detection sensor path; manual path tuning recommended. |
| Building height | ||
| Single-story | GoodGround-floor and first-story windows suit rope-anchor setup; minimal rope length required and safe operator control. | GoodTether range optimized for ground-floor and patio window coverage without ladders. |
| 2 – 3 storiesthey differ | DependsSecond and third stories are feasible with extended rope and secure anchor points; operator must maintain visual contact and rope tension. | GoodSecond-story windows accessible via tether from ground-level dock; roof anchor point or balcony ledge may extend reach. |
| 4+ stories | PoorAbove three stories, rope management, anchor reliability, and operator control become impractical; professional equipment required. | PoorTether length and safety constraints cap reach below third-story exterior windows; manual access required. |
| Power preference | ||
| Corded OK | GoodCorded tether design is the primary operation mode; 4800Pa suction is consistent throughout the session. | GoodRobot operates on dock-powered water and electrical supply; corded operation is the only mode available. |
| Cordless preferred | PoorHOBOT S7 Pro is tethered only; no cordless or battery-backup option exists. | PoorProduct is not cordless; auto-clean dock requires mains power and water supply connection. |
| No preference | GoodIf your setup accepts a tethered robot, the S7 Pro is a solid fit; rope anchor is the only constraint. | 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.
HOBOT S7 Pro
You gain consistent 4800Pa suction but forfeit mobility; the rope tether anchors the robot to one location per setup.
Auto-pathing saves manual repositioning on framed windows, but edge sensors require frequent cleaning to maintain navigation reliability.
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.
HOBOT S7 Pro
- Panes with no interior outlet or fixed object to tie to
- The unit runs on mains power through a 4 m cord extending to 8 m, and HOBOT's instruction is to tie the 4.5 m safety rope to a fixed object indoors. Where the room behind the glass offers neither, the setup HOBOT specifies cannot be built.
- Panes the operator cannot reach to place and retrieve the unit
- The S7 Pro is set on the glass by hand and taken off by hand. It does not travel between panes or openings, so every pane needs an operator present to anchor the rope, start the run and remove the unit afterward.
- Operators wanting cordless operation
- The S7 Pro runs from mains power and stays corded throughout a session. Its built-in UPS is backup power that holds adhesion for about 20 minutes if that power is interrupted, not a cordless operating mode.
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.
HOBOT S7 Pro
- After every use: Wipe water droplets from mop pads and sensors; store pads in dry state to prevent mold.
- Weekly: Check safety rope for knots, fraying, or kinks; unwind snags before next session.
- Every 3-6 months: Replace mop pads (~$30-40 per pair) if streaking or reduced scrubbing action is visible.
- Monthly: Clean suction motor intake filter and motor housing with dry brush to maintain 4800Pa suction.
- Annually: Inspect edge sensors for lens damage; replace rope if it shows signs of wear or reduced strength.
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.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
