Robot vacuum runs but has very weak suction and leaves debris behind

Safety first: Turn OFF the robot and remove the dust bin.

• Step 1 – Empty bin completely: Open and tap the bin to remove compacted dirt.
• Step 2 – Clean or replace filters: Remove the pre-filter and HEPA filter. Tap out dust; if heavily soiled or older than recommended, replace with genuine OKP filters.
• Step 3 – Inspect suction inlet: Shine a light into the suction opening on the robot and the outlet on the bin. Remove any lodged debris.
• Step 4 – Check for air leaks: Ensure the bin seats firmly and the rubber seals are intact.
• Step 5 – Test suction: Power ON and feel for airflow at the exhaust. If still weak, the suction motor may be worn and require replacement.
