Safety first: Remove the battery before cleaning filters.

Step 1 – Empty dust cup: Completely empty and wipe the dust cup with a dry cloth.
Step 2 – Clean or replace filters: Remove pre-motor and HEPA filters. Tap off dust. If washable, rinse with cold water and allow to dry fully for 24 hours. Replace filters if the odor persists.
Step 3 – Clean cyclone: Brush dust from cyclone cones and mesh.
Step 4 – Air out vacuum: Leave the vacuum (without the battery) in a dry, ventilated area for several hours.
Step 5 – Prevent recurrence: Empty the dust cup after each use and avoid vacuuming damp materials.

Vacuum smells musty or dusty when running.
