The cover is detachably disposed on the housing and has an accommodating groove. The air tube is positioned in the accommodating groove and extendible and flexible, the air tube is capable of being extended to outside the accommodating groove and retracted to be accommodated in the accommodating groove, and a bending angle and an extension direction of the air tube is changeable by flexibility. The dust collecting head is disposed at the air tube, and is positioned in the accommodating groove when the air tube is shortened to be accommodated in the accommodating groove. The filter material is disposed inside the housing and close to the cover. The gas guiding device is disposed inside the housing.

A surface cleaning apparatus having an upright assembly, a power source, and a coiled electrical cable. The upright assembly including a frame and a telescoping handle at last partially extending from the frame and movable between an extended position and a contracted position. The coiled electrical cable being provided within a portion of the telescoping handle and configured to uncoil or coil when the telescoping handle is moved between the extended position and the contracted position.

An environmental control unit comprises a housing, a vacuum cleaner, a filtration unit, and a blower. The vacuum cleaner is positioned in the housing and is configured to receive a tool contaminant stream produced by at least one tool. The vacuum cleaner filters particulate matter from the tool contaminant stream, thereby producing a filtered air stream. The filtration unit is also positioned within the housing and comprises at least one filter. The blower is positioned within the housing downstream of the filtration unit. The blower is configured to create negative air pressure within the second compartment to draw an area contaminant stream from an exterior of the environmental control unit into the housing. A second blower may also be present. The blower draws the filtered air stream and the area contaminant stream through the at least one filter in the filtration unit to produce a filtered mixture stream.

A wet-dry vacuum device assembly comprises a housing and a motor-fan assembly mounted in the housing. The motor-fan assembly is arranged to generate an air flow along an airflow path between a dirty air inlet and a clean air exhaust. The wet-dry vacuum device comprises a tank positioned along the airflow path and arranged to capture liquid entrained in the dirty air flow. The wet-dry vacuum device further comprises a removable pump accessory mountable to the housing. The removable pump accessory comprises pump and a fluid inlet in fluid communication with the tank and the pump. A fluid outlet is in fluid communication with the pump and connectable to an exterior hose. The pump is arranged to move captured liquid in the tank from the fluid inlet to the fluid outlet.

A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

A vacuum cleaner includes a vacuum motor configured to draw air through the vacuum cleaner; a battery configured to supply electricity to the vacuum motor; and a control system configured to control the supply of electricity from the battery to the vacuum motor. The control system is configured to switch the vacuum cleaner between a first power mode in which electricity is delivered from the battery to the vacuum motor at a first power level, and at least a second power mode in which electricity is delivered from the battery to the vacuum motor at a second power level which is lower than the first power level. The control system is configured to monitor the extent of operation of the vacuum cleaner in the different power modes, and to provide an alert if usage of the vacuum cleaner in the first power mode exceeds a threshold.

An animal feces retrieval apparatus that is configured to facilitate the removal of animal feces for either disposal or re-use. The animal feces retrieval apparatus includes a frame that is secured to a user's back utilizing nylon shoulder straps. Operably coupled to the frame is the motor assembly wherein the motor assembly is operably coupled to a hose assembly. A controller is secured to the hose assembly and provides a user interface for control and operation of the animal feces retrieval apparatus. The controller provides a first mode and a second mode of operation of the animal feces retrieval apparatus. The motor assembly includes a motor that can be either combustible or electric. The animal feces retrieval apparatus includes a receiving receptacle having a liner configured to receive and retain incoming matter. The hose assembly includes a flexible section that facilitates directional manipulation of the nozzle of the hose assembly.

A vacuum cleaner includes an odor neutralizer and dust plume abatement system. The odor neutralizer and dust plume abatement system delivers a mist to a working air path of the vacuum cleaner, such as at or upstream of a working air treatment assembly defining a portion of the working air path.

A hand vacuum cleaner has an air treatment chamber, which comprises a stationary portion and an openable portion. The openable portion is moveably mounted by a mount between a closed position in which the air treatment chamber is closed and an open position in which the air treatment chamber is open. The Air treatment chamber has an air outlet comprising a screen and the screen is moveable with the openable portion.

A surface cleaning apparatus has a cyclone with multiple cyclone air inlets, and a header that is upstream of at least some of the cyclone air inlets.
