Why Your Robotic Cleaner Won’t Move

If your robotic pool cleaner isn’t moving as expected, several factors could be causing the issue. This guide will help you troubleshoot and resolve the problem step by step.

1. Water Temperature Too Low

Issue: If the pool water is too cold, the cleaner may struggle to move.

Solution: Ensure the water temperature is above 35°C for optimal performance. If the water is too cold, wait for it to warm up before using the robot.

2. Unbalanced Pool Chemistry or Slippery Walls

Issue: If the pool's pH levels are too high or too low, or if algae or biofilm is present, the robot may not move as expected.

Solution:

• Check and balance the pool chemistry—keep pH, chlorine, and alkalinity within the recommended range.
• Brush the pool manually to remove algae, biofilm, or other slippery residues.
• Shock the pool if algae buildup is severe, then allow the chemicals to stabilize before running the cleaner again.

3. Clogged or Dirty Filters

Issue: A clogged filter can restrict water flow, preventing the robot from generating enough suction to move as expected.

Solution:

Clean the filters after each use, even if they look clean. Small particles can dry and clog the material.

Test the robotic cleaner without a filter basket, if cleaner climbs walls without filter basket, filter needs to be cleaned or replaced.

4. Debris in the Impeller

Issue: If the impeller (which helps with suction and movement) is blocked, the robot may not generate enough force to move as expected.

Solution:

• Unplug the power supply before checking.
• Use a Phillips-head screwdriver (do not use a power drill) to open the impeller cover.
• Remove any debris and reassemble the cover.
• If your robot has side grilles, check them for obstructions as well.

5. Not Enough Cable Slack

Issue: If the cable is too short or tangled, it may prevent the robot from moving as expected.

Solution:

• Ensure the cable is long enough to match the longest dimension of your pool.
• Avoid excess cable in the pool to prevent tangling.

By addressing these potential issues, your robotic cleaner should regain its ability to move as expected and keep your pool spotless. If problems persist, consult your user manual or contact customer service for further assistance.
