A hand vacuum cleaner has a suction motor and fan assembly, an air treatment member and a pre-motor filter. The front end of the air treatment member is forward of the pre-motor filter media and the front end of the suction motor is forward of the pre-motor filter media.

A surface cleaning apparatus, such as a fluid delivery or steam mop, comprises a handle assembly comprising a steam distributor and a foot assembly pivotally attached to the handle assembly and comprising a base housing. The foot assembly can be used in two positions, whereby opposing sides of a cleaning pad on the base housing can selectively engage a surface to be cleaned. The foot assembly is further swivelable relative to the steam distributor, such that fluid can be delivered to the surface to be cleaned in both of the two use positions.

A pivoting and swiveling floor treatment appliance includes a lock-prevention member that prevents a body from becoming pivotally locked in a forward/backward direction when a portion of the body is in a swiveled position. The lock-prevention member may move relative to an appliance head and to a portion of the body that swivels. In some embodiments, components of the lock-prevention member contribute to locking the swivel of the body when the body is pivotally locked.

A hand vacuum cleaner wherein the central longitudinal axis of the air treatment member extends generally horizontally and the suction motor axis of rotation extends generally vertically.

A dust collecting device includes a tank and a main body housing a motor and detachably attachable to an upper part of the tank. A handle and a cover are both provided in an upper part of the main body. The handle is capable of being raised and turned down around a handle rotation shaft. The cover is capable of being opened and closed around a cover rotation shaft and covers a housing portion provided in the main body in a closed position. The cover rotation shaft is provided in parallel to the handle rotation shaft. The cover rotation shaft is positioned closer to a grip portion of the handle than the handle rotation shaft so as to overlap with a part of the handle. The handle rotation shaft is positioned closer to the cover than the cover rotation shaft so as to overlap with a part of cover.

The present invention provides a liquid replacement device and a cleaning system. The liquid replacement device is provided with: a first body provided with a first connection portion that can be connected to an outside, and the first connection portion provided with a clear liquid outlet for outputting a clear liquid and a dirty liquid inlet for inputting a dirty liquid. The first body is provided with a first clear liquid tank that can accommodate the clear liquid, a first dirty liquid tank that can accommodate the dirty liquid, a clear liquid output channel connected between the clear liquid outlet and the first clear liquid tank, and a dirty liquid input channel connected between the dirty liquid inlet and the first dirty liquid tank. The liquid replacement device can enhance the efficiency of the cleaning operation and has cost and aesthetic advantages.

A hand vacuum cleaner can include an air inlet conduit having an inlet conduit axis, a suction motor and fan assembly having a suction motor axis of rotation, and a cyclone unit comprising a cyclone chamber having a cyclone axis of rotation. The inlet conduit axis can be generally parallel to the cyclone axis and when the inlet conduit axis is horizontally disposed, the inlet conduit axis is positioned above the cyclone axis and a projection of the inlet conduit axis intersects the suction motor.

A handheld extraction cleaner includes a unitary body provided with a carry handle, and further provided with a supply tank, a recovery tank, and a suction source, all of which are carried on the unitary body. The various components of the extraction cleaner can be arranged for a balanced weight in hand. The supply tank can be integrated with a fluid distributor in a removable, modular unit.

A portable cleaning assembly is provided. The cleaning assembly comprises a fluid dispensation path for ejecting at least a first and a second cleaning solution from the assembly. The dispensation path comprises at least one shared segment, and a second fluid or solution is preferably passed through the shared segment wherein the second fluid comprises a solvent and is operable to clean at least one of the shared segment and an ejection nozzle associated with the shared segment.

An apparatus is provided which is capable of cleaning soiled concrete or other hard surfaces using significantly less water and detergent than typical pressure washers. A dual brush mode allows for more surface treatment. A safety electrical system allows the system to be used safely outdoors. The highly maneuverable maintainer utilizes industry standard components from floor maintenance equipment integrated with a horizontally stable wheeled platform, as well as, an adjustable and wear-compensating suspension system that can accommodate a variety of surfaces. The result is a low noise, low carbon footprint, low resource apparatus that moves easily in any direction while providing direct rotary brush scrubbing to clean soiled concrete or other hard surfaces.
