Vacuum runs but emits a strong dusty or musty odor from the exhaust

Safety first: Turn OFF the vacuum, remove the battery pack, and work in a well-ventilated area. Do not use harsh chemicals inside the vacuum.

• Step 1 – Thoroughly clean dust bin: Empty the bin and wipe it with a slightly damp cloth. If the manual allows, wash the bin with mild soapy water, rinse well, and dry completely before reinstalling.
• Step 2 – Clean or replace filters: Tap out dust from pre-motor and HEPA filters. If washable per manual, rinse with lukewarm water and let dry for at least 24 hours. Replace filters that remain smelly or discolored.
• Step 3 – Check for wet debris: Never vacuum wet materials with a Bomann cordless vacuum. If you have, inspect for mold or residue and clean affected plastic parts thoroughly.
• Step 4 – Deodorize gently: After cleaning and drying, you can place a small amount of baking soda in the bin (not on filters) for a short time, then empty before use.

Persistent odors after cleaning may indicate deeply contaminated filters or internal foam parts, which should be replaced.
