CLEAR S
Clean Like a Pro.
The CLEAR S delivers everything you need in a premium robotic pool cleaner — powerful suction, active scrubbing brushes, and UltraFilter™ technology that leaves your floor, walls, and waterline sparkling clean with almost no effort on your part.
The Ultimate Machine
Powerful Cleaning, Without the Complexity
Most pool owners don't want a science project — they want a clean pool. The CLEAR S combines dual pump motors, dual drive motors, and intelligent navigation into one reliable robot that does the hard work for you, cycle after cycle.
Drop it in, press start, and let it climb walls, scrub the floor, and polish the waterline while you get back to enjoying your pool.
Built to Perform
More Motors. More Power.
Four breakthroughs work together to deliver a deeper, smarter clean than entry-level pool robots can match.
Two pump motors and two drive motors team up for stronger suction and surefooted climbing on every surface.
Quad active scrubbing brushes break loose dirt, algae, and biofilm before sweeping it up — not just passing over it.
An intelligent navigation system maps your pool in real time for efficient, complete coverage on every cycle.
The advanced C9 microprocessor coordinates the motors, sensors, and cleaning cycles for smarter performance.
Crystal-Clear Water
Catches What Other Cleaners Miss.
A massive, top-loading filtration system pulls everything from leaves to microscopic particles straight out of your water.
UltraFilters™ capture fine debris down to 1 micron — trapping pollen, dust, and dirt that slips through standard filter baskets.
The high-capacity UltraBin™ offers up to 500 ft² of filtration and lifts out from the top for fast, mess-free cleanup.
Every Inch, Every Time
Full Pool Coverage.
The CLEAR S doesn't stop at the floor. It climbs the walls and scrubs the waterline for a top-to-bottom clean.
Cleans floors, walls, and waterline in a single cycle for pools up to 50 ft long.
Precision waterline cleaning scrubs away the oily, grimy ring most robots leave behind.
A built-in temperature sensor lets you check your pool's water temperature in real time.
Set It and Forget It
Smart Control, Made Simple.
Schedule cleanings, switch modes, and steer the robot from anywhere — right from your phone.
The CLEAR app lets you start, stop, schedule, drive, and monitor your robot — plus activate Pick-Up mode for easy retrieval.
The onboard weekly timer keeps your pool clean automatically — choose Regular, Ultra, Fast, Floor, or Waterline modes.
