Vacuum emits a musty or unpleasant odour during use

Safety first: Remove the battery pack. Do not vacuum liquids with a Henry cordless dry vacuum.

Step-by-step:

• 1. Empty and wash bin: Remove the dust bin and wash it with mild detergent and warm water. Rinse thoroughly and dry completely.
• 2. Clean or replace filters: Tap out dust from filters. If the manual allows, wash them and let them dry for at least 24 hours. Replace heavily soiled or damaged filters.
• 3. Deodorise: Once dry, you can place a small vacuum‑safe deodorising tablet or a teaspoon of baking soda in the bin (check manual for compatibility).
• 4. Avoid wet debris: Do not vacuum damp materials; they can cause mould growth inside the bin and filters.
