Seauto models compared
| Model | Position in the range | Certified cleaning depth |
|---|---|---|
| SAT20 | Entry-level and most affordable model | Not stated |
| SAT 20 Pro | Versatile model with a higher depth certification | 5 m |
| SAT 40 | Flagship model | 4 m |
| Crab | Model with a different design, updated for 2026 | 5 m |
All four models can clean the floor, walls and waterline. The SAT20 is the entry-level option, but check its permitted working depth against your pool before buying. The SAT 20 Pro has a higher depth certification and may be suitable for a deeper pool.
The SAT 40 is the flagship model, but its stated depth limit is one metre less than those of the SAT 20 Pro and Crab. A flagship designation does not necessarily mean a cleaner is intended for the deepest pools.
The Seauto Crab, updated for 2026, adds a different design to the range and is certified to five metres. That depth expands its potential use in deeper residential or commercial pools. Depth alone, however, is not enough to determine whether it is suitable for a particular pool.
What depth certification means
The depth rating indicates the maximum depth at which the cleaner is intended to operate. Compare it with the deepest part of your pool, not just the average depth. A robot rated to four metres is not a suitable choice if it needs to work deeper than that.
Also check compatibility with your pool's dimensions, shape and surface. Battery life, filtration, maintenance, price and availability may matter too, but specific details are not provided in this overview.
What the robot cleans and what the owner still needs to do
Floor cleaning helps collect settled debris, wall cleaning reduces deposits on surfaces, and waterline cleaning covers the area where dirt accumulates at the water's surface. A robot can therefore reduce manual work, but it does not replace all pool care.
Owners still need to maintain the cleaner and look after water quality and the pool's filtration system. Waterline cleaning alone does not guarantee that algae will not form or that the pool will never need additional manual cleaning.
