Can I wash the Digital Motorbar cleaner head or its brush bar?

No, the Digital Motorbar cleaner head and its brush bar are not washable. To maintain optimum performance, you should check the brush bar regularly, clear any debris, and wipe it over with a damp lint-free cloth. You should never put any part of your machine in a dishwasher or use detergents, polishes, or air fresheners. (Page 9)
