Abstract

A power tool with a housing (12) and a tool (18, 22) located thereon such that it is capable of being driven in a rotating and/or oscillating manner, the tool being operable as directed using vacuum flow, in particular using a vacuum cleaner. The power tool is made particularly powerful by the fact that a radial turbine wheel (34) with forward-guiding and rearward-guiding vane rows (44, 48) functions as the drive.
