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.

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.

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

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 Z1 Pro

The robot addresses all three core pool surfaces (floor, walls, waterline) in one cycle, but an independent review found first-run cleaning fell well short of that goal and only reached roughly 90 percent effectiveness after a firmware update.

Auto-parking at the waterline reduces the retrieval task compared to a fully submerged robot, but the same review found the five-minute window before it sinks back adds a different kind of attention requirement: promptness rather than physical retrieval.

Hayward AquaVac 6 Series

The filterless SpinTech canister removes cartridge and bag consumables from ownership entirely. In exchange the cleaner is a self-contained appliance that has to be lifted in and out and emptied after each cycle, with no plumbing integration to fall back on.

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 Z1 Pro
Buyers wanting a mature, multi-generation product line
The Z1 Pro is Dreame's first robotic pool cleaner, with no prior generation's field record to draw on.
Owners who cannot check the app promptly after a cycle
An independent review documented the unit sinking back into the water roughly five minutes after parking at the waterline if it is not retrieved.
Saltwater pools above 5,000 ppm
The manufacturer's documented saltwater rating tops out at 5,000 ppm.
Hayward AquaVac 6 Series
Above-ground pools and inflatable structures
Oversized and designed for rigid in-ground geometry; cord management and wall navigation do not transfer.
Compact or oddly-shaped pools
Mapping assumes rectangular or standard curved geometry. Pools with complex depth changes or sharp ledges confuse navigation.
Owners avoiding corded equipment entirely
No battery-powered variant in this series; power cord of 50-60 feet is standard and non-negotiable.

What stays your job

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

Dreame Z1 Pro
  • Retrieval window: The robot climbs to the waterline when a cycle ends but sinks back after about five minutes if not lifted out, so a person needs to watch for the app notification rather than retrieve it at leisure.
  • Filter: The 180-micron filter needs periodic emptying and rinsing; no disposable filter cost was found in sources reviewed.
  • Remote/app setup: Mode selection happens in the app; live steering uses the included LiFi optical remote, which is not usable underwater alongside the app.
Hayward AquaVac 6 Series
  • After each cycle: Lift the cleaner out, open the debris canister by its red release knob and empty it, then rinse the canister with fresh water.
  • Weekly: Rinse the cleaner body with fresh water to clear pool chemistry, and check the brushes and rollers for embedded grit.
  • Monthly: Inspect the drive rollers and brush surfaces for wear and confirm wall contact is consistent.
  • Seasonally: Inspect the floating cable and the control unit’s supply cord for abrasion or cuts. The control unit runs from a GFCI-protected receptacle and should not be run through an extension cord. Store the cleaner and control unit indoors over winter if the pool is not used year round.
  • As needed: Untwist the floating cable, and replace brushes once worn.
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.
