A swimming pool is meant for switching off - not spending every weekend scrubbing it. That is exactly the point of the Seauto Crab Pro: a pool-cleaning robot that gets on with the job while you get on with enjoying the sunshine.
Seauto has been building pool robots since 2021, and the Crab Pro is one of its strongest models to date. For the final days of AliExpress Summer Sales, which end on Wednesday night, the price drops to €215 instead of €285 with the code SS6FR30 - a solid €70 saving.
AliExpress Summer Sales deal and purchase conditions
At this price point, the Crab Pro undercuts many headline cordless pool robots, which are often sold for twice as much. On the buying side, AliExpress advertises free, fast delivery, VAT already included, and the manufacturer’s two-year warranty, plus 15 days to return it for a refund if it does not meet expectations.
If you would rather spread the cost, PayPal’s interest-free payment in 4 lets you pay €53.75 today, with the remaining balance split across the following three months. It is a genuinely strong deal for anyone after a dependable, high-performing cordless robot to avoid the routine pool-cleaning chore.
Why choose the Seauto Crab Pro?
Where plenty of robots stop at the pool floor, the Crab Pro goes further. It cleans the walls too, climbing up them with ease, and it works right up to the waterline - the area where greasy residue tends to build up as the pool gets used. Two brushes (one at the front and one at the rear) scrub the surfaces while powerful suction lifts debris, and its basket captures everything from leaves to the finest grains of sand.
Smarter coverage with sensors and obstacle detection
To cover the whole pool without repeatedly passing over the same area, the Crab Pro uses sensors to map the space and identify obstacles. Rather than roaming randomly, it moves in consistent lanes, and users report that it reaches everywhere - even in a sloped rectangular pool - without getting stuck in a corner.
Cordless use, battery life, app and maintenance
The most convenient part is that there is no cable at all. You place it in the water, start a cleaning cycle, then retrieve it once it is done - with no plug or hose to unravel. The battery provides up to 2 h 30 of continuous cleaning, which is enough to handle a full pool in one go, and you should allow around 3 hours for a recharge.
Better still, the battery is removable and can be replaced at end of life, which helps extend how long you can keep using the robot. When a cycle finishes, it returns to the edge on its own and stops there, so all you need to do is lift it out without getting much more than your hands wet.
A mobile app rounds things off. It is used to choose the cleaning mode (walls only, floor only, or both), set the duration and speed, and keep an eye on battery level. Honestly, it is fairly basic and does not offer much beyond that - but the robot works perfectly well without you fiddling with settings. Maintenance is just as straightforward: the basket rinses out in seconds under the tap, and the impeller can be removed without any tools. A few users simply note that the basket can be slightly fiddly to refit, though it does not spoil the overall experience.
It is hard to turn down a robot this practical at this price. The Crab Pro removes the need for manual cleaning, climbs the walls, reaches the waterline, and works fully autonomously while you do something else. With a 4.9 out of 5 rating and thousands of sales, this Seauto cordless robot on AliExpress has already won over plenty of buyers - and with the Summer Sales ending soon, it is a good reason not to hang about.
