Quick answer: Check the robot’s filter, brushes, suction ports, program, type of debris and surface condition. Fine dust sometimes needs a different filter or manual vacuuming.
A robot may drive around the pool, but the result may not match expectations. The cause is often simpler than a fault: a full filter, worn brushes, the wrong program or fine dust.
What to check
Only take the robot apart according to the manual. Many issues are solved by cleaning the filter basket and checking the brushes.
- full or clogged filter
- worn brushes
- clogged suction ports
- tangled cable
- unsuitable program for the floor or walls
Fine dust on the bottom
Some particles are so fine that the robot’s basic filter cannot catch them. A finer filter cartridge or manual vacuuming outside the filter can help.
- pollen
- construction dust
- dead algae
- sand or soil after a storm
When to consider a service company
Consider a service company if the robot does not drive straight, stops, does not charge, does not turn the brushes, or repeatedly shows an error.
