Abstract
A cleaning implement for cleaning a soft or a hard surface comprises a handle, a sweeper head, rotating blades and a collection bin. The bottom wall of the collection bin includes an opening that is covered by a cleaning sheet during the cleaning operation. The height of this bottom wall relative to the surface being cleaned is adjustable by a user. The cleaning implement can be used with a disposable cleaning sheet, which includes protrusions that are capable of removing entangled hair from a carpet surface.
