Quick answer: First clean the robot’s basket or filter cartridges, check the brushes, the cable, the program and the type of debris. Fine dust may need a different filter.
A robotic cleaner isn’t a substitute for fixing bad water or filtration. But when it leaves streaks, doesn’t climb the walls or doesn’t pick up debris, a simple check reveals a lot.
How to recognize the problem
- The robot moves around, but debris stays behind.
- Some debris falls back out after removal.
- It doesn’t climb the walls or it flips over.
- The cable twists or the robot skips part of the pool.
What to safely check first
- Clean the filter baskets or cartridges.
- Check the brushes and the suction passage.
- Verify you’re using the correct program.
- For fine dust, try a finer filter.
- Check the cable and correct submersion of the robot.
- If the water is cloudy, first address chemistry and filtration.
What not to do
- Do not leave a clogged filter in the robot.
- Do not use the robot in conditions outside the manual.
- Do not expect the robot to fix algae or bad water values.
Prevention
- Clean the baskets after every cycle.
- Don’t store filter cartridges dirty.
- Regularly check the brushes and the cable.
When to call a service
Call a service if the robot doesn’t move, repeatedly reports a motor error, isn’t watertight, or has a damaged cable.
FAQ
Why doesn’t the robot pick up fine dust?
It may have too coarse a filter, or the fine particles are being stirred up. A finer filter cartridge and calmer vacuuming help.
Should the robot climb the walls?
It depends on the model, surface, pool shape and program. Not every robot is designed for walls and the waterline.
