Robot vacuum shows E8 and suction stops, though the robot may still move.

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

• Empty dust bin: Open the bin and dispose of all debris. Tap gently to loosen compacted dust.
• Clean or replace filter: Remove the HEPA or foam filter from the bin. Tap it gently outdoors or replace it if heavily soiled or damaged. Do not wash non-washable filters.
• Inspect air path: Look into the suction inlet and air channels for blockages. Remove any clogs with a soft brush.
• Reassemble and test: Refit the filter and bin securely, then power ON and start cleaning.
• If E8 continues: The suction fan motor may be overheating or failing and will need replacement by a service technician.
