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.

Generalized

Any task, any setting

Environmental

Handles new obstacles without help

III

Conditional

Finishes familiar jobs on its own

Assisted

Runs preset routines, needs rescue

Manual

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.

Dreame L40 Ultra Gen 2

Suction rose from 11,000Pa to 25,000Pa, roughly a 127 percent increase over Gen 1, but cleaning time per floor-area remains stable; the duty-cycle ceiling is unchanged.

The Dual Flex Arm is an edge-reach mechanism, swinging the mop pad and extending the side brush toward baseboards and corners; it does nothing for obstacle avoidance or entanglement, which are handled by the navigation sensors and the TriCut brush.

MOVA P70 Pro Ultra

The heated-mop dock adds convenience but commits owners to consumable cost. Pad replacements and hot-water mineral deposits drive estimated $120-160 annually beyond vacuum-only consumables.

The top suction setting carries an undocumented noise cost. MOVA publishes no decibel figure for the P70 Pro Ultra at any power level and no independent measurement exists, so the difference between running at 30000Pa and running quieter cannot be stated.

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.

Dreame L40 Ultra Gen 2

High-pile carpet or shag flooring: Mainstream vacuum suction loses effectiveness on pile heights above 25mm; owner reports document reduced cleaning on Berber-class carpet.
Homes with dense pet hair mats: Anti-tangle on this machine comes from the TriCut brush, not from the Dual Flex Arm, which is an edge-reach mechanism. Brush checks remain a weekly job if shedding exceeds light-to-moderate levels.
Multi-part dock setup constraints: The all-in-one dock needs floor space, an indoor outlet, and reachable clean and dirty water tanks. Auto-empty itself produces noise during its 2-3 minute cycle.

MOVA P70 Pro Ultra

Homes that need cleaning under low furniture: The robot stands 103.8 mm (4.09 in) tall, so it will not pass under sofas, beds or cabinet toe kicks with less than about 4.1 inches of clearance. Nothing in the app changes that; the areas it cannot enter stay uncleaned.
5GHz-only or unstable Wi-Fi networks: Setup and app control need a 2.4GHz network; there is no Bluetooth-only fallback. A dropped connection does not change how the robot cleans, since the map and path planning are onboard, but app control, the live map and app-triggered schedules are unavailable until it reconnects.
Apartments under 800 sqft with frequent manual rerouting needs: Self-mapping optimizes for open floor plans; obstacle avoidance requires clear pathways. Homes with dense furniture, small rooms, or frequent layout changes force frequent no-go-zone edits and interruptions.

What stays your job

The upkeep ownership hands back to you, whatever the autonomy level says.

Dreame L40 Ultra Gen 2

Weekly: Refill the dock’s clean water tank and empty the dirty tank; cadence tracks how much mopping is scheduled.
Weekly: TriCut brush hair removal in high-shedding homes; manual cleanout ~5 min.
Monthly: Filter inspection and tap-clean; wipe the dock washboard and the mop pad seats.
Roughly quarterly: Dust-bag swap. Dreame rates the dock for up to 100 days of hands-free operation before a change, and bags sell in multipacks at single-digit dollars each.
Every 3-6 months: Replace the DuoScrub mop pads once the fabric mats or stops releasing dirt.
Annually: Brush replacement if wear is visible.
As needed: Wipe the dock charging contacts and the robot’s sensor windows.

MOVA P70 Pro Ultra

Weekly: Empty the station’s dirty-water tank and refill the clean-water tank; wipe out the wash tray.
Monthly: Rinse or replace the filter cartridge (~$8-12).
Every 3-6 months: Inspect the side brush and replace it if the bristles have flattened (~$6-10 per pair); clear mineral deposits from the wash tray and water path with a descaler intended for appliance water circuits, not vinegar.
As needed: Replace the dust bag when it is full; MOVA publishes no fixed interval and stations of this type are generally rated in the 60 to 100 day range.
As needed: Replace mop pads once the pile has matted; clear fiber from the wheels and the main brush.

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.
