Cordless vacuum smells musty or emits an unpleasant odor during use

Safety first: Remove the battery before cleaning. Do not use harsh chemicals inside the vacuum.

• Empty and wash bin: Remove the dirt bin and wash it with mild soap and warm water. Rinse thoroughly and allow to dry completely.
• Clean or replace filters: Wash washable filters with cool water and let them dry for at least 24 hours. Replace any filters that remain smelly or discolored.
• Clean cyclone and air path: Use a dry brush to remove dust and hair from the cyclone shroud and internal passages. Avoid soaking non-removable cyclone parts unless the manual explicitly allows it.
• Prevent recurrence: Empty the bin after each use, especially after picking up pet hair or food debris. Do not store the vacuum with a full bin.
• Optional odor control: Use only Bissell-approved scented filter inserts or deodorizers if available for your model; do not place loose powders inside the vacuum.
