NanoFilters
Next Gen Filtration Captures MoreHigh-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.
Waterline / Tileline Cleaning
Clean where other robots can't90% 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.
Wall Climbing
Provides floor and wall coverageWall 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.
SmartPhone App
Control your robot from anywhereWith 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.
Gyroscope
Gyroscopic Sensors for Superior NavigationGyroscopes detect the orientation of the robot by measuring linear acceleration and the angular rotational velocity. The advanced sensors monitor and control position, orientation, direction, and rotation for more effective cleaning coverage, superior climbing and wall/waterline cleaning.
Anti-Tangle Swivel
No more tangled cordsWith 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.
Ultra Efficient
Save Hundreds of Dollars Cleaning Your Pool a YearA robotic pool cleaner saves hundreds of dollars a year in energy when compared to pressure-side or suction-side cleaners. Powered by energy efficient DC motors, a robotic pool cleaner can be 90% more efficient than its counterparts.
Plug and Play
Simply plug in and start cleaningSet up has never been easier. No installation needed. Your robot is ready to go right out of the box. No extra pumps, plumbing, or anything else needed. Simply plug it in and start cleaning!
Precise Navigation
Navigate Any ObstacleThis technology ensures that the most efficient route is used to clean your pool floor. So smart, the system automatically navigates around obstacles and quickly returns to its route. You'll want to look for SmartNav, as we found it performed best in our testing.
