Seauto Shark
Low cost cordless robot with 10,400 mAh battery
Researched by Riley Hart · updated Oct 30, 2026
Is the Seauto Shark worth it? An older cordless robot now sold off cheaply, with a big battery, strong waterline scrubbing and good fine dirt capture. It costs $399 as of Nov 4, 2026, and 2 independent reviewers tested it.
An older cordless robot now sold off cheaply, with a big battery, strong waterline scrubbing and good fine dirt capture. Both reviewers fought a buggy app, and PCWorld saw it miss parts of the floor. A sensible buy at the clearance price for a simple pool; skip it if you need dependable app control or long term model support.
Best for: budget buyers wanting long runtime. Skip if: you need a reliable app.

What independent reviewers found
- Picked up about 85% of organic debris and over 90% of artificial leaves in a 3+ hour floor only run, scrubbed the tile line well, and docked at the wall every time. The app was buggy and a firmware update never completed.
- PCWorld
- In a 20,000 gallon in-ground pool it ran more than 3 h in floor only mode, about 5 h total, recharged in 2 to 3 h, crossed raised drain covers and cleaned in a linear pattern. The app kept disconnecting.

Questions buyers ask
Is the Seauto Shark still sold?
Yes. Seauto's US store lists it at $399 with a note about limited leftover stock.
Can it use the fine filter while climbing walls?
PCWorld says the high filtration insert adds weight that hinders wall climbing, so it is meant for floor only mode.
How long does it take to charge?
Seauto's store says 4.5 hours. The spec sheet Pro Tool Reviews printed says 2 to 2.5 hours, and the reviewer saw 2 to 3 hours.
