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

I
Manual

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.
Kärcher RCX 4
PIN-gated, account-locked operation is a real anti-theft measure, but it also means the mower cannot simply be handed to a new owner without the prior account holder’s approval.
The rain sensor protects the machine by returning it to dock, at the cost of an interrupted, not merely paused, mowing cycle.
Litheli Skope 800 AI-VISION
A published slope rating and coverage figure put the Skope 800 ahead of some CES-stage competitors on disclosure, but cutting width, cutting height, and drive layout are still unpublished.
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.
Kärcher RCX 4
- US buyers needing a confirmed USD price and local retail channel
- Pricing was found only in EUR at European retailers; no confirmed US MSRP or availability was located.
- Owners who mow on a fixed schedule regardless of weather
- The rain sensor automatically interrupts an in-progress cycle and returns the mower to dock rather than continuing through rain.
- Buyers wanting a documented blade-stop-on-lift timing spec
- Lift and anti-tilt sensors are documented, but no independent test of blade-stop timing was found.
Litheli Skope 800 AI-VISION
- Buyers needing a mower available for purchase now
- No price, release date, or retail availability has been announced.
- Buyers who require a documented blade-safety specification
- No blade-stop, lift, or tilt safety provision has been documented for this model.
- Buyers wanting independently verified object-recognition performance
- The claimed 200-plus object-type recognition has not been independently verified.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Kärcher RCX 4
- Blades: Floating cutting deck for terrain adaptation; blade replacement interval and cost are not published by the manufacturer.
- Boundary setup: No wire to bury; up to 10 zones and no-go areas are set in the app.
- Charging station: Dock-cleaning cadence is not documented.
- PIN/account: Every operation requires a PIN code, and reassigning the unit to a new owner requires the prior owner’s approval.
Litheli Skope 800 AI-VISION
- Blades: Not published.
- Boundary setup: Litheli states no boundary wire or RTK station is required; camera-based NEO-FSD mapping replaces both, per the manufacturer.
- Battery: Swappable Infinity Power Share (IPS) pack shared across Litheli’s cordless tool line, per the manufacturer.
- Charging station: Not documented.
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.
