My unit is not climbing the walls

Many but not all of the BWT pool robots are intended to climb walls.  Please make sure your robot is equipped to climb walls by referring to your owners manual. 

Please note that the robot will only climb the walls a third of the overall time in cleaning the pool.  It does not clean the walls on every pass.

If your robot is intended to climb walls but doesn't, there could be an issue with the suction of the robot.  The suction is what keeps the robot fixed to the wall to climb.  If something with the suction is not correct, it will not climb.  There could be a couple different issues with the suction of the robot.

1. Check to make sure your filters are clean.  If there is not strong enough suction, the robot cannot stay fixed to the wall.  Make sure your filters are clean before each cleaning cycle.
2. If your filter baskets are clean , it could be because the propellor is either broken or seized due to hair, string, or leaves.  
   1. Remove the robot from the pool and disconnect from power. Inspect the propellor for accumulation of hair, string, or leaves that can block propellor from turning.                               NOTE: When removing the cover for the propellor, make sure to use a manual flat tip screwdriver.  Do not use power tools for this operation.
3. Check to make sure the chemical levels in the pool are correct.
   1. Chlorine level should be normal.  If not, "shock" the pool.  Remove robot before treatment.

   2. Make sure that PH is between 7.2 and 7.6. if not within those parameters- make proper adjustments.  Remove the robot from the pool during this treatment.

4. If you have checked all of the above and everything seems okay, but the robot still does not climb walls, it is time to send it to a service center.  For help in finding service centers, refer to our article Where can I find a service center for repair or parts?
