According to one embodiment, a handy-type vacuum cleaner has a vacuum cleaner main body, a gripping part for use for gripping the vacuum cleaner main body, and a blower attachment to be attached to/detached from the vacuum cleaner main body. The vacuum cleaner main body includes an electric blower, a dust-collecting device, a main body connecting port, a suction air path, and an exhaust air path. The dust-collecting device stores the dust and dirt sucked by driving of the electric blower. The blower attachment is inserted into/extracted from the main body connecting port. The suction air path communicates between the main body connecting port and the dust-collecting device. The exhaust air path communicates with the exhaust side of the electric blower. The exhaust air path communicates with the blower attachment when the blower attachment is inserted into the main body connecting port.

The invention relates to the use of a suction-cleaning attachment of a cleaning device for cleaning the interior of motor vehicles by means of a suction airflow, having a housing which has a suction duct for conducting the suction airflow, there being in the housing in addition to the suction duct a compressed air duct for conducting a compressed airflow, and/or the housing being assigned in addition to the suction duct a compressed air duct for conducting a compressed airflow, and a grip region for gripping the suction-cleaning attachment with one hand being provided on the outside of the housing. According to the invention, a switch for controlling the compressed airflow is provided, and the switch is arranged on the grip region such that the switch can be operated by the hand holding the grip region.

A cleaning system for pavement joints controlled and driven by a motor. A wheeled housing carries a nozzle system where a stream of pressurized or forced air is directed through rotating nozzles to clean the joint surfaces. The rotational speed (RPM) of the motor is selectively controlled by actuation of a valve by the operator, and allows the operator to selectively control the rate of rotation of the nozzles are required by the state of the surface to be cleaned. A suction head is further movable over the joint surfaces to remove the debris dislodged by the nozzle system and airflow.
