ABSTRACT:
A vacuum cleaner has a power brush which projects dirt particles directly into a specially formed and located vacuum nozzle in such a manner that low air consumption can be used. The vacuum nozzle has an inlet extending along the full axial length of the power brush. Inclined grooming brushes may be provided to eliminate wheel tracks. The front wall forwardly of the power brush may be modified to provide front edge cleaning. A cordless upright vacuum cleaner may advantageously be provided having a cleaning performance comparable with that of mains powered upright cleaners.
