All robot window cleaners. Every measure below is plotted against the full class, so a difference can be read against how much the class itself varies.

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

One action, on command
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.
Ecovacs Winbot Mini
Lightweight and corded means a 3.5 m mains cable, not a battery, sets working reach; every pane needs an outlet within that radius, and the robot is placed and retrieved by hand.
Hobot 298
Mains power removes recharge cycles, and an embedded UPS holds the robot in place for 20 minutes through an outage, but the 4 meter cord ties the machine to a socket within a few paces of the 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.
Ecovacs Winbot Mini
- Large homes with frequent multi-story window coverage needs
- Manual repositioning between floors and buildings is labor-intensive. The robot is designed for one pane per cycle; multi-floor properties negate the efficiency gain.
- Windows you cannot reach to place and retrieve the robot
- The Mini is set on each pane by hand and taken off the same way, and it works within reach of a 3.5 m mains cable. Exterior faces above ground level, skylights and any pane a person cannot safely load it onto fall outside what this machine addresses.
- Exterior windows requiring consistent all-weather operation
- Suction performance degrades with moisture and dust buildup. Exterior exposure demands daily pad inspection and rinse cycles.
Hobot 298
- High-rise or multi-story installations requiring extended reach
- The power cord is 4 meters and the supplied safety rope is 4.5 meters, so both the socket and the rope's indoor anchor point have to sit close to the pane being worked. Windows further from an interior socket than that are outside what this model reaches.
- Homes without adjacent power outlets or outdoor outlets within cable run
- Extension cord use is discouraged by manufacturer for safety. Interior outlet management becomes critical; wet-environment electrical safety is owner's responsibility.
- Specialty or curved glass surfaces
- Square pad geometry and fixed nozzle positioning leave corners uncleaned. Tempered or heavily tinted windows challenge optical edge detection; manual repositioning is frequent.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Ecovacs Winbot Mini
- After every use: Rinse microfiber pad with distilled water to remove minerals and dust.
- Weekly: Check motor intake for clogs; clean suction port with soft brush.
- Monthly: Inspect safety tether for wear; wipe suction cups and magnets with damp cloth.
- Every 3-6 months: Replace microfiber pads (~$15-20 per pair).
Hobot 298
- Weekly: Rinse pad and inspect nozzle for mineral deposits; test suction by listening for motor speed consistency.
- Monthly: Clean intake ports and motor filter with soft brush; soak nozzle in distilled vinegar if spray pattern weakens.
- Every 3-4 months: Replace cleaning pads (~$20-25 per pair); inspect power cable for insulation damage.
- Annually: Replace motor intake filter (~$15); deep-clean nozzle assembly by soaking in 50/50 vinegar-water solution.
- As needed: Replace vacuum motor assembly if suction falls below specification (~$80, typical at 5-6 year mark with regular use).
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.
