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

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.

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.

04 Ownership

What the numbers leave out.

The trade-off

What each design gives up to be good at what it is good at.

HOBOT-S6 Pro

Manual launch and repositioning. The robot does not autonomously navigate between windows or edges; a user must place it, start it, and move it to the next pane, it is not a set-and-forget window cleaner.

Cord management. The 5 meter power cord caps the working radius from a socket, and its secured DC connector is built to stay joined rather than be extended. Placement has to account for that cord and, separately, for the safety rope, without either fouling the other.

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.

HOBOT-S6 Pro
Fully autonomous outdoor window cleaning
HOBOT-S6 Pro requires manual launch and manual repositioning between panes. It does not autonomously navigate or select windows to clean.
Homeowners with small tight window frames or muntins
Dual mops and head width are optimized for larger panes. Narrow muntins and divided-light windows may require manual cleaning or repositioning to avoid frame contact.
Users needing coverage far from a socket
The power cord is 5 meters, about 16 feet, on a secured DC connector designed not to pull apart in use. That is the working radius from a socket, and there is no cordless variant of this model.
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.

HOBOT-S6 Pro
  • After every use: Rinse dual mop pads; inspect suction gasket for mineral deposits or debris.
  • Weekly: Soak mop pads in vinegar solution if hard-water spotting is visible; clean edge sensors.
  • Monthly: Replace or deep-clean suction gasket; check cord for insulation damage or kinks.
  • Every 3–6 months: Replace mop pads (~$25–$35 per pair); verify safety rope for frays.
  • Annually: Inspect vacuum motor performance; if suction noticeably reduced, contact HOBOT support for service options.
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.
