01 Classification
What each one does on its own.
The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.
V
Generalized
Any task, any setting
IV
Environmental
Handles new obstacles without help
III
Conditional
Finishes familiar jobs on its own
II
Assisted
Runs preset routines, needs rescue

02 Assessment
Where they actually differ.
The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

03 Measured against the class
How far apart is a long way?
A number only means something next to the spread it sits in. Each track below is the real range across every classified robot in the class, with the median marked.

04 Ownership
What the numbers leave out.
The trade-off
What each design gives up to be good at what it is good at.
Mamibot iGLASSBOT W120-T
Auto-path on uniform framed glass is reliable; suction on textured panes and the manual’s outright prohibition on frameless glass are the binding constraints, not cleaning quality.
Sub-$200 dual-pad scrubbing is accessible, but rope anchoring, hand-wetted pads and per-panel remounting keep the owner in the loop every session.
Tosima W5 Window Cleaning Robot
A documented Triple Safety System combining suction, edge detection, and a rope exists, but the rope itself carries no published load rating, so the system’s real fall-protection margin cannot be verified from public sources.
The unit runs on mains power with a battery reserved for power loss, trading true cordless freedom for a longer expected runtime per pane.
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.
Mamibot iGLASSBOT W120-T
- Frameless glass, and textured, frosted or curved surfaces
- Mamibot's manual prohibits use on frameless glass outright, which is the flat case owners most often assume is fine. Suction loss on textured and frosted surfaces is separately documented across owner reports.
- Users expecting fully autonomous multi-panel cleaning runs
- The unit is remounted and the rope re-anchored between separate panels. There is no dock, no multi-panel routing and no resume.
- Homes with upper-floor windows far from power outlets
- The unit is mains-powered and ships with an adapter and extension cable. Windows beyond that run are impractical, and the tether sets the working height as much as the glass does.
- Owners needing cordless battery-only operation
- The W120-T runs from mains power. The 600 mAh cell on board is a backup that holds the unit on the glass if power is cut, not a runtime battery, so use is restricted to windows near an outlet.
Tosima W5 Window Cleaning Robot
- Buyers needing a documented tether load rating for high-rise or high-stakes panes
- No source documents a load or weight rating for the safety rope; Unknown is the honest answer, not an assumption of safety.
- Buyers expecting cordless operation
- The robot runs on mains power during normal use; its internal battery is a power-failure backup only, not a primary cordless power source.
- Buyers who want independently verified coverage or corner-cleaning performance
- All capability claims trace to manufacturer or retailer text; no independent test data was found.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Mamibot iGLASSBOT W120-T
- Before every use: Confirm the backup battery is fully charged, and tie the safety rope to a secure indoor fixture.
- After every use: Rinse and wring the microfiber pads; allow to air-dry before storage.
- Weekly: Inspect the safety rope along its length for fraying, and check the fixture it is tied to.
- Monthly: Wipe the suction cup and intake filter with a damp cloth to maintain seal integrity. Do not spray or pour water onto the device.
- Every 30-50 sessions: Replace the microfiber cleaning pads (sold separately).
- As needed: Inspect the power cable and connector for wear near strain-relief points.
Tosima W5 Window Cleaning Robot
- Per-pane setup: Attach the safety rope to a sturdy anchor point before placing the robot on the glass, per the manufacturer’s own safety instructions.
- Water refill: Refill the onboard water reservoir for the auto-spray system; capacity is not documented.
- Cloth rotation: Attach and periodically swap the cleaning rags (8 shipped with the unit).
- Relocation: The robot must be manually moved and re-tethered for each additional pane; it does not persist coverage between panes.
05 Evidence
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.
