Wall climbing requires a full charge and the correct mode.
Wall climbing requires a full charge and the correct mode. All X1 models (base, Pro, and Pro Max) support Floor + Wall + Waterline cleaning. The base X1 cleans floors, walls, and waterlines; the X1 Pro adds HydroComm compatibility; the X1 Pro Max adds surface skimming and stronger suction.
Wall Mode Requirements (All X1 Models)
To clean walls: select Wall+Floor or Auto mode in the app before starting the cycle. Ensure the robot has a full charge — wall climbing uses significantly more power than floor cleaning. In pools deeper than 8 feet, the robot may not reach the full wall height on a single charge. Run a second cycle for deeper pools.
Robot Climbs to Mid-Wall and Stops
Common cause: battery not fully charged, or the pool wall material (pebble aggregate, rough plaster) has high friction reducing grip. Fix: (1) Fully charge before use. (2) Clean the robot’s drive rollers — debris on rollers reduces grip. (3) Try a second wall mode run immediately after a floor mode run. In very deep pools (> 9 ft), partial wall coverage per cycle is normal.
Waterline Cleaning (All X1 Models)
Waterline cleaning is available on all X1 models (floor, wall, waterline modes). Surface skimming mode is exclusive to the X1 Pro Max. Activate it in the app via Wall+Waterline or Auto mode. The robot will travel along the waterline perimeter after completing the wall surfaces. Waterline cleaning requires the robot to operate very close to the water surface; ensure pool water level is within normal range (not below the skimmer mouth) for best results.
Pool Surface Compatibility
The X1 Pro / Pro Max works best on smooth plaster, fiberglass, and vinyl surfaces. Pebble Tec and rough aggregate provide less grip. Saltwater pools are compatible. Above-ground pools with sloped walls: the robot may slide rather than climb on walls steeper than 80°. Check the product spec sheet for exact wall angle compatibility.
