A vacuum cleaner including a suction inlet that provides entrance of a suction airflow, a suction source, a diffuser, a blower port, a duct, and a removable cap. The diffuser is in fluid communication with the suction source for diffusing the suction airflow and the diffuser includes a circumferential opening that surrounds the suction source such that the suction airflow travels through the opening into the diffuser. The duct is located downstream of the blower port with respect to the direction of the suction airflow and the duct includes an outlet. The cap is removably coupled to the blower port such that at least a portion of the suction airflow exhausts through the blower port when the cap is removed, and when the cap is coupled to the blower port the suction airflow is travels through the duct and exhausts through the outlet.

Provided is a vacuum cleaner including a cleaner body disposed at a position distant from the ground; moving wheels rotatably installed at both sides of the cleaner body and configured to rotatably support the cleaner body; a dust container installed at a front surface of the cleaner body located at a front of the moving wheels and configured to collect suctioned dust; and a suction hose connected to the front surface of the cleaner body and through which the dust is suctioned, wherein a center of gravity of the cleaner body is located at a rear side further than a vertical extension line of a rotating center of the moving wheels, and a rear end of the cleaner body becomes closer to the ground when travel of the vacuum cleaner is stopped.

A display input part 28 displays a first element relevant to operation of an electric blower 14, and a second element having trade-off relation with the first element. The display input part 28 receives input for changing a value of at least either one of the first element and the second element. A main control part 29 obtains, on the basis of the value after change received by the display input part 28, a value of the other of the first element and the second element. An indication control part makes the display input part 28 display the value obtained by the main control part 29. A driving control part controls driving of the electric blower 14, on the basis of the value of the first element received by the display input part 28 or the value of the first element obtained through calculation by the main control part 29.

A surface cleaning apparatus has a dirty air inlet and an air treatment member. The air treatment member includes a dirt collection region having an openable door. When an accessory is connected to the dirty air inlet, the openable door is inhibited from opening.

A cleaning apparatus may include at least one isolator configured to absorb mechanical vibration generated by contact between an agitator and a combining unit to reduce noise and/or vibration. The isolator may include at least one combing isolator disposed at least partially between the combing unit and the surface cleaning head. Alternatively (or in addition), the isolator may include a panel isolator disposed at least partially between a housing of the cleaning apparatus and a panel.

Ergonomic gripping mechanisms of handheld air movement apparatuses are provided. A handheld air movement apparatus may include a handle portion and a tool portion. The handle portion may include a grip, a trigger, and a handle pivot. The grip may have first and second ends. The trigger may be positioned toward the first end of the grip and the handle pivot may be positioned toward the second end of the grip. The tool portion may include a housing, a nozzle coupled to the housing, and a handle connection base. The tool portion may provide air movement into and/or out of the nozzle in response to a signal received from the trigger of the handle portion. The handle connection base of the tool portion may be pivotally coupled to the handle portion at the handle pivot to provide directional height adjustment of the tool portion with respect to the handle portion.

A handheld vacuum cleaner includes a dust cup assembly, a suction nozzle assembly and a handle assembly. The dust cup assembly includes a cup casing, an airflow generation device and a cyclone separation device, both of which are arranged in the cup casing, the airflow generation device being arranged above the cyclone separation device and positioned on a downstream side of the cyclone separation device, and an air vent being formed in a top of the cup casing. The suction nozzle assembly is mounted to the cup casing and defines a suction channel. The handle assembly is mounted to the cup casing and used to be held. With the structure, a blowing direction of the air vent is not towards a surface to be cleaned, so as to prevent the wind from the air vent blows away dust on the surface to be cleaned and hence ensure a cleaning effect.

A vacuum cleaner includes a cleaner body, a suction hose mounted at a front surface of the cleaner body to suck in dust, moving wheels provided at both sides of the cleaner body, rotating to move the cleaner body and rotatably supporting the cleaner body, wheel motors connected to the moving wheels and rotating the moving wheels, a detecting unit provided in the cleaner body and sensing inclination of the cleaner body to determine whether the cleaner moves and stops, a plurality of detecting members provided at a front surface of the cleaner body and located at both sides of the suction hose to detect an obstacle, and a controller for controlling the wheel motors according to detected signals of the detecting unit and the obstacle detecting members.

Ae multifunction vacuum cleaner includes a container body, which houses a suction unit of air flows from the outside; a filter of the air flows sucked from the outside; an accumulation tank of materials sucked from the outside and filtered by the filter; and a steam production unit and a system sending steam to the outside of the container body.

A hand vacuum cleaner has an air flow path extending from a dirty air inlet to a clean air outlet. A cyclone chamber positioned in the air flow path has a cyclone air inlet and a cyclone air outlet. A pre-motor filter is positioned downstream of the cyclone air outlet and a suction motor is positioned in the air flow path downstream of the pre-motor filter. The pre-motor filter is vertically spaced from the cyclone axis of rotation when the upper end of the hand vacuum cleaner is positioned above the lower end of the hand vacuum cleaner, and air travels generally rearwardly from the pre-motor filter to the suction motor.
