Key Features Comparison

Features

Waterline / Tileline Cleaning

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 robot 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.

T25No
W20No

Dolphin Sigma 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 dirtiest part of your pool, the waterline, where 90% of all algae and bacteria is in your pool.

T25Yes
W20No

Anti-Tangle Swivel Cable

Anti-Tangle Swivel

No more tangled cords

With an Anti-tangle Swivel, the robot can fully explore and clean your pool without ever getting stuck. The innovative design allows the robot to move freely 360 degrees around your pool, without ever knotting the cord.

T25No
W20Yes
