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 W2 Omni |
|---|---|---|
| Window style | ||
| Standard residential | GoodDesigned for standard horizontal-sliding and framed windows up to 86 inches; edge detection aligns with frame geometry. | GoodFlat, smooth glass with minimal framing works optimally. Edge detection excels on standard rectangular windows. |
| Large panes (8 ft+) | DependsLarger panes work but edge sensor coverage may miss frameless corners; manual repositioning may be needed. | DependsLarge single-pane windows may exceed dock suction radius or require mid-session repositioning on expansive home layouts. |
| Specialty / textured | PoorSpecialty glass (skylights, curved, skylights) and frameless designs exceed auto-pathing capability and edge-detection scope. | PoorFrosted, textured, tinted, curved, or decorative glass confuses optical sensors; edge detection fails and manual override required. |
| Frame style | ||
| Frameless / minimalthey differ | PoorEdge detection and auto-pathing depend on frame geometry; frameless windows have no reference edges for navigation. | GoodFrameless glass presents edge-detection advantages; optical sensors identify perimeter clearly without frame interference. |
| Standard mullions | GoodStandard aluminum or vinyl framed windows are the design target; edge sensor performance is predictable and reliable. | GoodStandard framed windows with aluminium or vinyl trim work well; dock-based edge mapping adapts to frame geometry. |
| Heavy bezels | DependsHeavy frames (steel, wood) are acceptable but may interfere with edge sensor readings near frame edges; test before full sessions. | DependsHeavy or ornate framing may interfere with edge-detection calibration or require manual sensor repositioning between cleaning cycles. |
| Building height | ||
| Single-story | GoodGround-floor and first-story windows suit rope-anchor setup; minimal rope length required and safe operator control. | GoodGround-floor windows align with dock placement in garage or utility room. Wall-mounting and suction-hose reach optimized for single-story deployment. |
| 2 – 3 stories | DependsSecond and third stories are feasible with extended rope and secure anchor points; operator must maintain visual contact and rope tension. | DependsTwo-story homes possible with dock on upper level, but long hose runs (>5m) may reduce suction pressure and increase runtime drain. |
| 4+ stories | PoorAbove three stories, rope management, anchor reliability, and operator control become impractical; professional equipment required. | PoorSafety rope limited to 5-meter length; high-rise and multi-story buildings exceed rope capacity and create unacceptable fall risk. |
| Power preference | ||
| Corded OK | GoodCorded tether design is the primary operation mode; 4800Pa suction is consistent throughout the session. | GoodDock operates on standard 120V or 240V outlet depending on region. Corded power enables continuous dock pad-washing without battery drain. |
| Cordless preferredthey differ | PoorHOBOT S7 Pro is tethered only; no cordless or battery-backup option exists. | DependsRobot is cordless but dock requires AC power for pad drying and water-pump operation. Dock must be wired; full cordless operation not possible. |
| No preference | GoodIf your setup accepts a tethered robot, the S7 Pro is a solid fit; rope anchor is the only constraint. | GoodDock-based architecture requires AC wall outlet, but robot operates cordless during cleaning sessions for up to 35 minutes per charge. |
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 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.
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 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.
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 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.
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.
