Cordless vacuum leaves fine dust smell or musty odor during use

Safety first: Remove the battery before cleaning. Avoid inhaling dust.

• Empty and wash container: Remove the dust container and wash it with mild soap and warm water if Kärcher allows. Dry completely.
• Clean or replace filters: Wash washable filters and let them dry for at least 24 hours. Replace non‑washable HEPA filters if they smell or appear discolored.
• Avoid vacuuming wet material: Kärcher cordless dry vacuums are not designed for wet debris unless specifically stated. Do not vacuum damp dirt or liquids.
• Regular maintenance: Clean the container and filters at least monthly in heavy use to prevent odors.
