Abstract
A suction device for cleaning textile floor coverings comprising a base member, a central housing, and a cover. A brushing device is detachably mounted closely adjacent to the base member. The base member has a tubular stub receiving a flexibly supported suction air connector sleeve of the brushing device. The dust chamber is located in the central housing and a dust air canal located within the housing of the suction device connects the tubular stub with the dust chamber. The suction blower and at least a portion of the electrical and/or electronic components are located in the base member resulting in a low center of gravity for the unit. The closely adjacent detachable mounting of the brushing device to the suction device avoids long vacuum hose and long electrical lines connecting the suction device to the brushing device.
