Robot vacuum leaves visible debris on floors; suction seems weak even though it runs normally.

Safety first: Turn off the robot and remove it from the dock before cleaning.

• Empty dust bin: Remove and empty the bin completely. Tap it gently to dislodge compacted dust.
• Clean or replace filters: Remove pre-filter and HEPA filter. Tap off dust outdoors. If washable, rinse with water and let dry fully before reinstalling. Replace filters if heavily soiled or damaged.
• Check suction path: Inspect the suction inlet and channels in the bin for clogs and clear them.
• Inspect brush: A clogged main brush can reduce pickup. Clean hair and debris from the brush and end caps.
• If suction remains weak: The suction motor or fan may be worn or partially blocked internally. Replace the suction motor assembly.
