Vacuum produces an unusual musty or dusty odor during use.

Safety first: Remove the battery and avoid inhaling dust during cleaning.

• 1. Empty and wash the dust cup: Remove the dust container and wash it with mild detergent and warm water. Rinse thoroughly and allow it to dry completely.
• 2. Clean or replace filters: Tap out dust from the pre-filter and HEPA filter. If washable per the manual, rinse and dry fully. Replace filters that remain odorous or discolored.
• 3. Clean cyclone surfaces: Wipe the cyclone shroud and internal plastic surfaces with a slightly damp cloth, then dry.
• 4. Avoid vacuuming damp material: Do not vacuum wet debris or liquids, as they can cause mold and odors.
• 5. Persistent odor: If the smell remains after thorough cleaning, replace the filter set with genuine Panasonic filters.
