It runs for up to 240 minutes on a single charge and cleans the floor, walls and waterline. The 2026 model uses AI navigation, four brushless motors and a mobile app for control.
Battery, dimensions and operating range
The cleaner is intended for larger private and commercial pools, with a stated operating depth of 0.5 to 5 metres. Its 10,400 mAh battery provides up to four hours of runtime and takes approximately 4.5 hours to charge. Allow for this charging time when planning the next cleaning cycle.
The unit measures 469 × 396 × 250 mm and weighs 9 kg. Its weight is worth considering when putting it into the pool and taking it out.
Motors and water flow
The SAT 40 has four brushless motors with a combined power output of 320 W. Its stated movement speed is 18 metres per minute. It travels along the floor and walls and reaches the waterline; it does not clean by moving across the water surface.
The stated water flow rate is 120 GPM, or gallons per minute. The available information does not say whether these are US or imperial gallons, so the figure cannot be converted unambiguously to litres per minute. The flow rate relates to the amount of water the cleaner processes while collecting debris.
Navigation and controls
AI navigation is intended to optimise the route around the pool, reducing overlap and missed areas. The cleaner supports multiple cleaning modes, which can be selected in the mobile app via Bluetooth. The available information does not specify the names or settings of those modes.
Filtration and cleaning surfaces
The filtration system has a capacity of 3.7 litres, with stated filtration fineness values of 180 μm and 90 μm. These values relate to the capture of particles of different sizes, but the available information does not explain the filter configuration. The larger debris container is particularly useful when collecting debris in a large pool.
The robot cleans the floor, walls and waterline, removing debris from the pool’s main surfaces. Mechanical cleaning does not replace water treatment or checks of water parameters.
Water resistance and use
The cleaner has a stated IPX8 rating for immersion in water. IPX8 alone does not specify an unlimited immersion depth or duration, and the available information does not provide the specific test conditions. The SAT 40 has a separately stated operating depth range of 0.5 to 5 metres.
Besides pool size and depth, consider the charging time and the unit’s weight when choosing a cleaner. The available information does not specify compatible pool surface materials.
