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 |
|---|---|
| Window style | |
| Standard residential | GoodDesigned for standard horizontal-sliding and framed windows up to 86 inches; edge detection aligns with frame geometry. |
| Large panes (8 ft+) | DependsLarger panes work but edge sensor coverage may miss frameless corners; manual repositioning may be needed. |
| Specialty / textured | PoorSpecialty glass (skylights, curved, skylights) and frameless designs exceed auto-pathing capability and edge-detection scope. |
| Frame style | |
| Frameless / minimal | PoorEdge detection and auto-pathing depend on frame geometry; frameless windows have no reference edges for navigation. |
| Standard mullions | GoodStandard aluminum or vinyl framed windows are the design target; edge sensor performance is predictable and reliable. |
| Heavy bezels | DependsHeavy frames (steel, wood) are acceptable but may interfere with edge sensor readings near frame edges; test before full sessions. |
| Building height | |
| Single-story | GoodGround-floor and first-story windows suit rope-anchor setup; minimal rope length required and safe operator control. |
| 2 – 3 stories | DependsSecond and third stories are feasible with extended rope and secure anchor points; operator must maintain visual contact and rope tension. |
| 4+ stories | PoorAbove three stories, rope management, anchor reliability, and operator control become impractical; professional equipment required. |
| Power preference | |
| Corded OK | GoodCorded tether design is the primary operation mode; 4800Pa suction is consistent throughout the session. |
| Cordless preferred | PoorHOBOT S7 Pro is tethered only; no cordless or battery-backup option exists. |
| No preference | GoodIf your setup accepts a tethered robot, the S7 Pro is a solid fit; rope anchor is the only constraint. |
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.

How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.
These robots share no measured specification with enough published figures to plot. That is a gap in the record, not a finding about the robots.
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.
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.
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.
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.
| Robot | Evidence status | Sources reviewed | Last assessed |

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.
