Key Features Comparison

Features

NanoFilters

Next Gen Filtration Captures More

High-tech, plated filters are able to capture microscopic algae, debris, sand, and more in your pool water - all while increasing water clarity. To use, just simply snap them in and your robot is ready. NanoFilters are a must have for any pool robot.

M400No

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.

QuantumYes
M400Yes

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.

QuantumYes
M400Yes

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.

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.
