Robot vacuum has weak suction and drives around aimlessly
Clogged filters and a full dustbin are the most common causes of reduced suction. Empty the dustbin after every second run and rinse the foam filter under running water once a week (allow it to dry completely before reinserting). Check the side brushes and the main brush for tangled hair and clean by hand. Aimless behaviour indicates dirty sensors – wipe these with a dry cloth. Place the charging station on an open, unobstructed surface so that the robot can reliably find it.
