Clean where other robots can't.

90% of the bacteria in your pool is on the waterline. Don't get confused with robots that are "Wall Climbing". There is a big difference. Waterline cleaning means the actively scrubs and sticks to the waterline scrubbing away this problem area in the pool. It is a feature you don't want to miss.

Dolphin Wall Climbing

Wall Climbing

Provides floor and wall coverage

Wall climbing allows the robot to clean and climb the walls of your pool. However, don't get this confused with waterline cleaning. A robot without waterline cleaning will only clean the walls of your pool. It will miss the dirtest part of your pool, the waterline, where 90% of all algae and bacteria is in your pool.
