The arrangement disperses static electricity residing on a surface over which the cleaner head 10 is being manoeuvred. The material may comprises up to 5% by weight of carbon nanotubes and the polymer matrix may include one of a polyamide, polypropylene, thermoplastic polyurethane, polycarbonate and polybutylene terephthalate. The at least one floor engaging portion may form part of a support member such as a wheel 48, 50 or skid. The surface treating appliance may be a vacuum cleaner with other parts of the appliance also being formed from the material. |
