Wyze robot vacuum runs but leaves visible debris and dust on the floor; suction seems weak.

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

• Empty dustbin: Remove and empty the dustbin after every cleaning cycle. Rinse the bin with water only if the manual allows, and dry completely before reinstalling.
• Clean or replace filter: Tap the filter gently to remove dust outdoors. Replace the filter every 1–3 months depending on use and environment.
• Check suction inlet: Inspect the opening between the brush chamber and dustbin for clogs. Use a small brush or compressed air to clear it.
• Inspect main brush: Remove hair and debris from the brush and end caps. Replace the brush if bristles are worn flat or deformed.
• Test suction: With the robot running, feel for airflow at the exhaust. If airflow remains very weak after cleaning, the vacuum fan may be partially blocked or failing and may need professional service.
