Troubleshoot using the following questions:
- What kind of debris are you looking to pick up?
- Are you using the right filter bag?
- Is the unit completely submerged in the water?
- Is there any rips or tears in the bag?
- When was the last time you replaced your filter bag?
- Is my unit charged?
- Do the batteries need to be replaced?
You may be using the incorrect filter bag for the debris you want to pick up, your filter bag may need to be replaced, your unit may need to be charged or have the batteries replaced, or your cleaner may not be submerged in deep enough water.
