Robot vacuum runs but suction is very weak compared to normal

Safety first: Turn OFF the robot and remove the dustbin.

Step-by-step:

• Empty dustbin completely: Remove all debris and tap the bin to dislodge compacted dust.
• Clean or replace filters: Remove pre‑filter and HEPA filter. Tap gently to remove dust. If washable per manual, rinse and dry fully. Replace if heavily soiled or older than recommended interval.
• Inspect suction inlet: Look into the suction opening and brush channel for clogs. Remove any obstructions.
• Check main brush: Ensure the main brush is clean and spinning freely; a jammed brush reduces effective suction.
• Test on hard floor: Reassemble and run the robot on a hard surface to evaluate suction.

If suction remains weak: The suction motor or internal seals may be worn. Motor replacement or professional service may be needed.
