Troubleshooting
CLEANER UNIT DOES NOT COVER THE ENTIRE POOL.
Filter is dirty.
Clean the filter.
There is not enough length of the floating cable in the water to reach
the far end of the pool, or the cable is tangled.
1. Verify that there is enough length of the floating cable in the water to
reach the far end of the pool.
2. Make sure that the floating cable is properly spread out and is not
tangled.
The angle of the floating handle affects the cleaner movement.
Increase diagonal angle of the floating handle (see "Adjusting Floating
Handle").
Pool pH level is incorrect.
Make sure that the pH level is between 7.2 and 7.6.
Chlorine level is incorrect.
Check water chlorine treatment and correct if required (Remove the
cleaner from the pool during the treatment.)
Propeller is broken or seized due to accumulation of hair.
1. Remove the top screws on the top outlet.
2. Check if the propeller is broken or needs cleaning.
Obstacle in the drive system of the cleaner unit.
1. Turn the cleaner unit carefully to view the underside.
2. Rotate the tracks and scrubbing brushes by hand. It should rotate but it
should not rotate freely.
3. Clean and remove obstacles and debris if necessary.
THE CLEANER DOES NOT CLIMB WALLS.
The cleaner is not climbing the pool walls.
1. Verify that your robotic cleaner is not a floor-only model.
2. Verify that P1, floor cleaning only, is not selected on the power and
control unit (see "Robotic Cleaner Programming").

Cable is not spread out before putting the cleaner unit into the pool.
Make sure that the floating cable is properly spread out and not tangled
before operating the robotic cleaner.
The length of the cable in the water is too long.
Verify that the length of cable in the water equal to the pool diagonal length
plus two meters.
Propeller is broken or seized due to accumulation of hair.
Check if the propeller is broken or needs cleaning (see "Checking Water
Outlet Propeller").
