Dyson DCO4 working but for spares/repairs (Heaton Chapel SK4)

This vac could be for spares or repair. Motor and suction fine but doesn't pick up well when using the roller brush bar. Bagless, easy to empty. Hose very long with good stretch for stairs but the tool attachment piece became fragile so tools slip when in use. Life time washable filter plus spare, all tools, long power lead.
