The blade includes a flat blade body that is coplanar with a reference plane dividing the fitting body and containing the longitudinal axis of the fitting.

A vacuum cleaner comprises a housing having a longitudinal axis. A motor-fan assembly is mounted in the housing and arranged to generate an airflow along an airflow path from a dirty air inlet to an air exhaust. A retractable nozzle defines the dirty air inlet and is moveably mounted on the housing. At least a portion of the retractable nozzle is arranged to move between a retracted configuration within the housing and a deployed configuration outside the housing. The portion of the retractable nozzle in the retracted configuration is aligned in a direction along the longitudinal axis and the portion of the retractable nozzle in the deployed configuration is aligned in a direction across the longitudinal axis.

A mopping module and a cleaning head. The mopping module includes a water tank, a mopping cloth, and a water volume control mechanism. A water tank hole is provided at a bottom portion of the water tank; the water tank hole communicates with the interior of the water tank; the mopping cloth is provided outside the bottom portion of the water tank; the water volume control mechanism comprises a knob and a water control tray; and by controlling the cooperation between the water control tray and the water tank hole via the knob, the amount of water flowing from the water tank to the mopping cloth through the water tank hole is adjusted.

A hand-held vacuum cleaner (100) is provided, including a dust cup (2), the dust cup includes a first cyclone, a cyclone assembly, and a filtration member. The cyclone assembly includes a plurality of second cyclones (22), a guiding channel (23) is defined between two of the plurality of the second cyclones (22), the guiding channel (23) is in communication with the first air vent and an airflow is guided to an outer circumference of the cyclone assembly by the guiding channel (23) along a tangent line to a circumferential wall of the second cyclone (22) adjacent to the guiding channel (23), each second cyclone (22) has an air inducing notch (222), each second cyclone (22) is provided with an air guiding pipe (221), the filtration member is disposed along the outer circumference of the cyclone assembly, and the airflow in the outer circumference of the cyclone assembly tangentially enters the second cyclone (22) through the filtration member and the air inducing notch (222).

A suction nozzle includes a nozzle body including a suction port. The suction nozzle also includes a rotary cleaning unit rotatably mounted in the nozzle body and having a cleaning element for cleaning a floor. Additionally, the suction nozzle includes an anti-winder mounted on the nozzle body and having a plurality of contact parts that overlap a side end of the cleaning element along at least a portion of a rotational path followed by the cleaning element of the rotary cleaning unit when the rotary cleaning unit is rotated.

A method and a device for scraping paint off from a surface and further configured with a vacuum cleaner for vacuuming scraped material. The device includes a cylindrical handle, a dorsal handle, a replaceable blade, a graduated shaped box, and a rotating adaptor. The cylindrical handle provides control and further includes a proximal end, and a distal end. The replaceable blade attached at proximal end of cylindrical handle for scraping paint off from surface. The graduated shaped box accommodates replaceable blade. The rotating adaptor integrated at proximal end of the cylindrical handle to adapt according to the size of the cylindrical handle to accommodate a vacuum hose attached with the vacuum cleaner and further allow full rotation of the attached vacuum hose. The replaceable blade is spaced apart from graduated shaped box in such a way that air from the vacuum cleaner flow between the replaceable blade and the graduated shaped box.

Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.

A vacuum cleaner, movable over a surface, includes a suction source, a suction port, and a dustpan attachment removably coupled to the suction port. The dustpan attachment includes a housing, a vacuum port, and a recess defined within the housing. The housing includes a top wall and a plurality of walls extending from the top wall to a bottom edge configured to contact the surface. The vacuum port extends through at least the top wall or one of the plurality of walls and is coupled to the suction port. When the bottom edge contacts the surface, the recess cooperates with the surface to form a suction channel having a suction inlet formed in a front of the housing and in communication with the vacuum port. The housing defines first and second ends. The bottom edge includes a sealing material that contacts the surface continuously between the first and second ends.

A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber, a first connector lip and a second connector lip. An opening is provided that allows air, dust and debris to be drawn into the dust chamber during use. The connector lips are provided for attachment to a vacuum device. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber.
