Filter Maintenance
The Dyson Big Ball Multi Floor Canister Vacuum features a washable filter. To maintain optimal suction, wash the filter regularly with cold water and allow it to air dry completely for at least 24 hours before reinserting. Note: Product specifications mention a 'Non-washable post-motor filter'. However, seller videos demonstrate washing a filter, which is typically the pre-motor filter. Always refer to your specific product manual for exact filter maintenance instructions.
