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.

S300Yes
Active 20Yes

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.

S300Yes
Active 20Yes

SmartPhone App Control

SmartPhone App

Control your robot from anywhere

With its SmartPhone App, you can schedule cleanings, manually control, and fine tune your pool robot. The app makes managing your pool cleaning effortless and convenient.

S300Yes
Active 20No

Anti-Tangle Swivel Cable

Anti-Tangle Swivel

No more tangled cords

S300Yes
Active 20Yes
