Cordless vacuum smells musty or dusty when running

Safety first: Remove the battery and empty the bin.

Steps:

• Deep clean bin and cyclone: Empty the bin and wipe it with a slightly damp cloth. If removable and washable, wash the bin and cyclone with mild detergent, then dry completely.
• Clean or replace filters: Tap out dust from filters and wash if allowed. If filters are stained, smelly, or deformed, replace them with genuine Hoover filters.
• Dry thoroughly: Ensure all washed parts are completely dry (24 hours) before reassembly to prevent mildew.

Regularly cleaning filters and bin (every 1–3 months depending on use) will prevent recurring odors.
