## Verdict

A cordless Dolphin that The Hook Up picked for pools with sand, silt or pollen, thanks to its fine filter, big bin and best in test waterline reach. The Pool Nerd found it cleans well but is not hands off, since every charge means fishing it out, and the retail warranty is just 1 year. At the current sale price it is a solid cordless pick; buy a corded Dolphin if you want true set and forget cleaning.

- Best waterline reach in The Hook Up test
- Cleans steps and shallow ledges

## Questions buyers ask

### How long does it run?

Maytronics offers 1.5, 2 or 2.5 h cycles. The Hook Up measured 2 h 38 min on one charge.

### Does it clean the waterline?

Yes. The Hook Up measured about 3 in of waterline reach, the best of the robots it tested.

### Can I check it in the app while it cleans?

No. Maytronics says the app works when the robot is above the waterline, and The Pool Nerd found it loses connection underwater.
