Seauto

Dreame
Up to three
All robot pool cleaners. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Seauto SAT40 | Dreame Z1 Pro |
|---|---|---|
| Pool type | ||
| In-ground | GoodManufacturer designs it primarily for inground pools up to 3,200 sq ft and 13 ft deep, matching this setup directly. | GoodManufacturer rates coverage up to 2,160 sq ft with no documented pool-type restriction; matches typical in-ground layouts. |
| Above-groundthey differ | DependsManufacturer states above-ground use is possible but designs the SAT40 primarily for inground pools; verify fit before buying. | GoodManufacturer documents above-ground compatibility within the same 2,160 sq ft and 5,000 ppm salinity rating as in-ground pools. |
| Mixed setupthey differ | DependsManufacturer positions this as an inground-first design; above-ground compatibility is only described as possible, not primary. | GoodCoverage and salinity ratings apply identically across pool types, so a mixed setup fits the same documented envelope. |
| Pool size | ||
| Small (< 400 sqft) | GoodWell within the manufacturer's 3,200 sq ft coverage rating and 240-minute runtime for a single cordless cycle. | GoodManufacturer's 2,160 sq ft rating comfortably covers pools this size, even with the shorter 80-minute full-cycle runtime. |
| Medium (400 – 800)they differ | GoodStill comfortably inside the 3,200 sq ft rated area, with margin left in the 240-minute runtime for full coverage. | DependsStill under the 2,160 sq ft rated area, but the full floor-wall-waterline cycle runs only about 80 minutes. |
| Large (> 800) | DependsManufacturer caps rated coverage at 3,200 sq ft; confirm your pool's exact size before buying if it runs larger. | DependsManufacturer caps rated area at 2,160 sq ft; larger pools may exceed that, and full-cycle runtime is only 80 minutes. |
| Debris load | ||
| Fine (sand / silt) | GoodDual filtration includes a 10-micron ultra-fine cartridge specifically for capturing fine debris like sand and silt. | GoodThe single 180-micron filter is coarser than fine-filtration competitors; sand or silt may pass through uncaught. |
| Leaves / large debristhey differ | DependsThe 250-micron cartridge is designed for coarser debris, but no independent source confirms how it performs on leaves. | GoodA 180-micron filter mesh readily captures larger leaf debris, which sits well above that particle-size threshold. |
| Algae / heavy fouling | DependsNo published or independently verified data addresses how the SAT40 handles algae or heavy fouling specifically. | DependsIndependent review found inconsistent mapping and debris left near steps even post-firmware; heavy fouling adds coverage risk. |
| Coverage you want | ||
| Floor onlythey differ | GoodManufacturer states floor cleaning in every cycle via AI Sonar Navigation, the least demanding of the SAT40's claimed coverage modes. | DependsFloor-only mode gets a generous 210-minute runtime, but independent review still found early-run navigation stalls of about ten minutes. |
| Floor + walls | DependsManufacturer claims wall coverage in every cycle, but no independent source confirms how consistently walls are actually reached. | DependsAdding walls drops full-cycle runtime to about 80 minutes; independent review found mapping inconsistent between runs before firmware fixes. |
| Floor + walls + waterline | DependsFull floor, wall and waterline coverage is a manufacturer claim only; independent confirmation of cleaning completeness was not accessible. | DependsFull coverage reached roughly 90 percent post-firmware in independent testing, with debris still documented near steps on best runs. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
A number only means something next to the spread it sits in. Each track 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: Noise, Weight.
Written on each record, and the only thing here every robot on the site carries.
What each design gives up to be good at what it is good at.
The manufacturer claims coverage of all core pool surfaces (floor, walls, waterline) plus corners, but no independent source confirms how completely or consistently that coverage happens in practice.
A lower list price than some competitors in this batch comes with a thinner independently verifiable record: no confirmed warranty term and no accessible third-party reliability evidence.
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.
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
The upkeep ownership hands back to you, whatever the autonomy level says.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.

Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
