Robot vacuum leaves clumps of hair or debris behind or spits debris out the back.

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

Step-by-step:

• Empty dustbin: Completely empty the bin and wipe it clean.
• Clean or replace filter: Tap-clean or replace the HEPA filter to restore airflow.
• Check main brush seating: Ensure the main brush is fully seated and the brush guard is latched; gaps can cause debris to be flung out.
• Inspect dustbin seals: Look for cracks in the bin or damaged rubber seals. Replace the dustbin if damaged.

Test the robot on a small area to confirm debris is now collected properly.
