Robot vacuum smells musty or dusty when running, even after emptying the bin.

Safety first: Turn the robot OFF and remove it from the dock before cleaning.

Steps:

• 1. Thoroughly clean dust bin: Empty the bin and, if the design allows, wash it with mild soap and water. Dry completely before reinstalling.
• 2. Replace filters: Install new genuine Miele filters (pre-motor and exhaust) if they are old or smell musty.
• 3. Clean air path: Use a dry cloth or soft brush to remove dust from the suction inlet and ducts.

When to call a technician: If odors persist despite thorough cleaning and new filters, there may be dust accumulation deeper in the unit or contamination near the motor, which should be cleaned by a professional.
