Waterline Cleaning
Scrubs the tide line where oils and scum collect — the dirtiest part of the pool. A must for inground pools.
Wall Climbing
Partial wall cleaning. These models don't reach the waterline, but they clean far more than floor-only robots.
Weekly Timer
Program the power supply once and the robot cleans on schedule — every day, every other day, or every third day.
Anti-Tangle Swivel
The cable spins freely as the robot turns, so it covers the whole pool without knotting up.
MaxBin™
A single top-loading basket that's 50-100% larger than standard cartridges and empties in seconds.
NanoFilters™
Pleated ultra-fine filters that trap silt, pollen and algae a standard mesh filter lets through.
Multi-Media™
Premier's exclusive filter set: fine filter, NanoFilter™, oversized leaf bag and a disposable bag option.
Smartphone App
Start, steer, schedule and read cleaning stats from your phone over Wi-Fi or Bluetooth.
Gyroscope
Gyroscopic sensors map the pool so the robot cleans methodically instead of bouncing at random.
Media-Alert™
Real-time filter tracking that tells you when the onboard filtration needs a rinse.
