## Verdict

A solid corded cleaner for in-ground pools up to 50 ft that scrubs the floor, walls and waterline and never needs charging. PCWorld measured about 90% debris pickup in an hour and 95% or more on the longest cycle. The catch is value: at $1,449 it carries only a 1 year warranty, while Dolphin's Premier and Sigma carry 3 years.

## Pros

- Cleans floor, walls and waterline
- No battery, so it can run as often as you like
- Ultra fine filter kit included
- Wi-Fi app with weekly timer

## Cons

- Only a 1 year warranty at $1,449
- Six piece filter cleanup is tedious (PCWorld)
- App was slow and dropped connections in PCWorld's test
- No caddy in the base package

Yes. Maytronics lists floor, wall and waterline cleaning with waterline scrubbing.
