-Clean the Filter Bag thoroughly so that the fine particles of dirt that get trapped within the fibers of the Filter Bag are removed. To test if the Filter Bag is inhibiting the cleaner’s performance, simply remove the Filter Bag and operate the cleaner without it. If the cleaner then pumps water strongly, and climbs the walls properly, the Bag most likely requires a thorough cleaning.
-Shake the Handle. Listen for the presence of water within it. The Handle should be lightweight and airtight without water in it. If water is present, please contact RobotShop or Aquaproducts Customer Service.
-Check that the Pump Motor is operating.
-Check that the Drive Belts and Drive Tracks are properly aligned and are taut, adjust or replace if necessary.
-Check for excessive wear of the Scrubbing Brushes and replace if necessary. Note: Rubber Brushes begin to stiffen in water less than 70oF which lessens their ability to climb pool walls.
-You may need to add Floatation. Your cleaner needs to properly climb the walls and to move left or right scrubbing the waterline in order to properly clean the entire pool.
-Check the surface of your pool walls. In rare instances (e.g., new pools) the pool walls may be slippery and require cleaning/brushing first. If algae has accumulated in your pool and there is a slick green or clear layer along the base of the walls, this impedes the climbing ability of your cleaner. We suggest you Shock* your pool and then manually brush and vacuum the dead algae from all surfaces to waste (not through the main filter) to remove the bulk of the algae from the pool. If you use your cleaner to remove the dead algae be aware that the Filter Bag may clog quickly, requiring several cleaning cycles and thorough Filter Bag cleanings.
NOTE: Your cleaner’s Brushes will become covered with algae. Thoroughly clean them to ensure traction for future use.
*IMPORTANT: When shocking your pool water, remove your cleaner from the water for at least 24 hours to allow proper dilution before returning the cleaner to the pool. Otherwise premature discoloration and wear of plastic and rubber components will occur.
Please verify these aspects which will help you in determining the problem with your robot.
