Abstract: A floor cleaning device includes a floor covering compartment having a cleaning opening, a vacuum generating device, a suction pipe that connects the floor covering compartment to the vacuum generating device so that suction force is applied on the surface covered by the cleaning opening, a cleaning head body that holds the floor covering compartment, and a vibrating device that causes vibration of the floor covering compartment relative to the cleaning head body. The periphery of the cleaning opening is adapted to contact a surface to be cleaned so that a sealed cleaning space is formed inside the floor covering compartment and over the portion of the surface covered by the cleaning opening. Strong negative pressure is built up in the sealed cleaning space to enhance suction efficiency. Vibration temporarily breaks the sealed state to facilitate moving of the floor covering compartment.

Abstract: A surface treating head assembly for an appliance such as a vacuum cleaner includes a head and a piston assembly operable to apply a force to the head. The piston assembly is connected to the main motor of the vacuum cleaner by a valve. When the valve is opened, suction airflow flows through tubes connecting the motor to the piston assembly. The resulting suction force causes the piston assembly to contract, thereby drawing the cleaner head downwards. Thus, the head is urged towards the floor surface so as to improve the efficiency of a cleaning operation.

Abstract: A double suction type sterilizing vacuum cleaner includes a base seat and an upper cover mounted on an upper side of the base seat. A main suction port is provided in the base seat. A hitting device is mounted on the base seat and adapted to hit a cleaning object under the base seat. A sterilizing lamp is mounted in the base seat for sterilizing purposes. A dust collecting box is detachably mounted to the upper cover and defines an air channel in communication with the main suction port. A secondary suction port is provided in the dust collecting box and in communication with the air channel. When the main suction port is blocked, an ambient air can be supplied to the air channel through the secondary suction port, facilitating the release of the blocking situation in the main suction port.
