Abstract: A cleaner head for a cleaning appliance, comprising a brushbar, a housing defining a chamber which at least partially surrounds the brushbar, the chamber having a dirty air inlet and a dirty air outlet, and a scraper having a working edge which extends in the longitudinal direction of the brushbar. The scraper is arranged such that, in use, the working edge scrapes debris entrained by the brushbar from the brushbar. The working edge has a profile which is shaped such that debris which accumulates at the working edge is drawn by the airflow through the cleaner head along the working edge towards the dirty air outlet.
