An unpleasant, musty or dusty smell comes from the exhaust air during use.

Safety first: Remove the battery before cleaning filters. Do not use the vacuum without filters installed.

• Step 1 – Empty and wash bin: Remove the dust bin and wash it with mild detergent and warm water. Dry completely before refitting.
• Step 2 – Clean or replace filters: Wash washable filters as per the Tower manual and allow them to dry for at least 24 hours. Replace non‑washable HEPA filters with a genuine Tower HEPA filter cartridge if they smell or appear discoloured.
• Step 3 – Clean cyclone surfaces: Wipe accessible cyclone parts with a slightly damp cloth and dry thoroughly.
• Step 4 – Regular maintenance: Clean filters every 1–3 months depending on usage to prevent odours.
