All robot pool 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.

Generalized

Any task, any setting

Environmental

Handles new obstacles without help

III

Conditional

Finishes familiar jobs on its own

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.

None of these robots carries a scored assessment yet, so there is nothing to plot here. The classification and evidence below still apply.

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.

Not compared, because fewer than two of these robots carry a published figure: Price, Suction, Charge time, Noise, Weight, Height.

04 Ownership

What the numbers leave out.

The trade-off

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

Degrii Zima Pro

A 360-degree, 20-plus-sensor radar array and a 250W triple-motor pump are a more elaborate design than the Zima Lite’s, but the main unit’s dependence on a tethered floating battery pack is a real added component to manage that the Lite does not have.

A one-click ‘climb to waterline’ command reduces how far a person has to reach to retrieve the unit, but does not remove the retrieval task entirely.

Roborock RockAqua P1

A first pool robot from a vacuum maker: the camera and route-planning know-how is proven indoors, the underwater hardware is not.

Shallow-ledge cleaning is the headline claim, and nobody outside Roborock has shown it working on a real sun shelf yet.

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.

Degrii Zima Pro

Buyers who need a confirmed current price before deciding: Current MSRP was not confirmed in sources reviewed; Degrii's own pages showed unpriced or sold-out listings at points during this research.
Buyers who want a single self-contained body: The Zima Pro's main unit is tethered to a separate floating battery pack rather than carrying its own battery internally, unlike the Zima Lite.
Buyers who require independently verified cleaning performance before purchase: No independent, non-manufacturer test of the Zima Pro was located during this research; the most detailed third-party coverage found identified itself as sponsored content.

Roborock RockAqua P1

Anyone who needs a pool robot this season: It cannot be bought anywhere yet. The earliest reported launch is January 2027 in Australia and New Zealand, with no price and no US date.
Buyers who rely on an established repair network: This is Roborock's first pool robot. Its parts channel, warranty terms and service path for submerged hardware have not been published.
Very large pools needing a published size rating: Roborock has published a runtime of up to 3.5 hours but no maximum pool length or area, so fit for a large pool cannot be checked yet.
Pools with persistent algae on plaster walls: No brush type, scrub mechanism or wall-cleaning cycle detail has been published, so performance on stuck algae is undocumented.

What stays your job

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

Degrii Zima Pro

After every use: Send the one-click climb-to-waterline command, lift the robot and its floating battery pack out by hand, and empty the 6.5 L filter basket; rinse the mesh with a hose.
After every use: Recharge the floating battery pack between runs; a full charge covers up to 210 minutes in floor mode.
Weekly: Inspect the 11.5 ft tether cord between the robot and the battery float for cuts, kinks, or abrasion.
Monthly: Check the scrubbing brushes for wear and wrapped debris, and swap between the 180-micron and 100-micron baskets if the debris mix has changed.
Seasonally: Store the robot and the battery float indoors over the closed season and do not leave the lithium pack fully discharged in storage.
As needed: Replace the scrubbing brushes and filter cartridges as they wear (Degrii’s warranty treats both as one-year consumables), and restock the water purification packs sold as a dedicated accessory for this model. No replacement interval or part pricing was found in the material reviewed.

Roborock RockAqua P1

After every use: Retrieve the robot from the waterline and empty the 4-liter basket.
After every use: Rinse the two-stage 180 and 70 micron filters.
After every use: Recharge the battery before the next cycle.
As needed: Clear hair or debris from brushes and drive surfaces.
Seasonally: Clean, dry and store the robot out of direct sun at the end of the season.

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.
