ROBOTIC POOL CLEANERS / MODEL-SPECIFIC REPAIR

Why Is My Aiper Scuba S1 Leaving Dirt Behind?

Quick answer: Take it out of water, remove and rinse debris basket/filter, ensure filter seats and its mesh is intact.

Safety first: Remove the robot from the pool using the approved retrieval method. Power it off and dry the charge port before attaching the OEM charger. Never open its sealed battery case or test submerged motors on a dry surface.
