The present invention discloses a portable vacuum cleaner having a rotatable vacuum assembly. The vacuum cleaner comprises a nozzle assembly including a nozzle cavity, a canister assembly pivotally connected to the nozzle assembly, a dust bag mounted to the canister assembly, a dirty air pathway providing fluid communication between the nozzle cavity and the dust bag and a suction generator for generating a vacuum that draws dirt and debris from the nozzle cavity to the dust bag. The nozzle assembly having a nozzle mount rotatably coupled to the canister assembly to spin about a rotation axis and an angled nozzle rigidly extending from the nozzle mount at an acute angle to the rotation axis. The nozzle assembly is adapted to rotate and could move back and forth for effective collection of dirt and debris.

A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

A nozzle of a cleaner includes a nozzle housing having a first flow path extending in a left-right direction of the nozzle and a second flow path extending in a front-rear direction of the nozzle; first and second rotation cleaning units disposed behind the first flow path and spaced apart from each other in the left-right direction, the second flow path being positioned between the first and second rotation cleaning units, first and second driving motors disposed on opposing sides with respect to a centerline of the second flow path to rotate the first and second rotation cleaning units; mops attached to each of the first and second rotation cleaning units and an axis of the first driving motor and an axis of the second driving motor extend in a non-parallel angle with respect to the centerline of the second flow path.

A vacuum cleaner attachment generally includes a cleaning element that floats relative to a suction conduit of the vacuum cleaner attachment. The cleaning element is supported on a support structure that is movably coupled to a housing and is biased towards a floor, for example, as a result of the weight of the cleaning element support structure. The cleaning element may be permanently attached to the support structure or may be a removable or disposable pad or sheet attached to the support structure. The floating cleaning element may be supported between the suction conduit and one or more wheels of the vacuum cleaner attachment. The vacuum cleaner attachment may be removably attached to a vacuum cleaner, for example, to be used interchangeably with other surface cleaning heads.

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.

An intelligent cleaning device, comprising: a machine body (100); and a cleaning assembly (200) that is detachably connected to the machine body (100) along the forward or backward direction of the machine body (100). The cleaning assembly (200) comprises a liquid containing box, a connecting plate and a flexible cleaning body that are stacked. The liquid containing box is detachably connected to the machine body (100) along the forward or backward direction of the machine body (100), and the liquid containing box at least partially surrounds the outer side of a fan in the machine body (100). The connecting plate is detachably connected to the liquid containing box along the forward or backward direction of the liquid containing box. The flexible cleaning body is detachably connected onto the connecting plate. Each time the flexible cleaning body is replaced, same is convenient to operate and may prevent damage from being inflicted on the intelligent cleaning device that is easily caused by disassembling the liquid containing box in the prior art. At the same time, the whole structure of the intelligent cleaning device is beautiful and compact.

A vacuum accessory may include a head including a head body defining an inlet and a fitting interface, the head body extending from a fitting interface to a base and enclosing a cavity. A fitting includes a fitting body symmetrically disposed about a longitudinal axis of the fitting. The fitting body defines a fitting inlet, an outlet, and a flow path connecting the fitting inlet and the outlet. The fitting is connected to the head at the fitting interface and a fluid flow path fluidly connects the inlet and the outlet. A blade is removably coupled to the head and at least partially disposed within the cavity of the head. 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 nozzle for a cleaner includes a nozzle main body, a rotation cleaning unit rotatably connected to the nozzle main body, the rotation cleaning unit including a rotation plate provided with a mop, and a water supply flow path configured to supply water from a water tank to the rotation cleaning unit, the water supply flow path having an outlet. The rotation plates includes a central shaft, at least one water passage hole spaced apart from the central shaft in a radial direction to receive water directly from the outlet of the water supply flow path, and a water blocking rib located outside of the water passage hole in the radial direction.

A nozzle for a cleaner has a nozzle main body including an intake channel to suction air. The nozzle includes first and second rotary cleaning units spaced apart from each other in a lateral direction under the nozzle main body. Each of the first and second rotary cleaning units includes a rotary plate coupled to a dust cloth. The nozzle further includes a first driving device to drive the first rotary cleaning unit and a second driving device to drive the second rotary cleaning unit. The nozzle includes a water tank to store water. Further, the nozzle has a water supply channel to supply water in the water tank to the rotary cleaning units. The nozzle has a water pump and a pump motor to drive the water pump to pump the water to the dust cloth.

A floor nozzle for a vacuum cleaner has a housing, and a base on the housing constructed for sliding in a working direction on a floor and formed with a downwardly open slot-shaped port delimited relative to the direction between a transversely extending front port edge and a transversely extending rear port edge. The base has, extending forward from the front port edge, a part-cylindrical and downwardly convex front surface with a front radius of curvature and centered on a transversely extending symmetry axis and, extending rearward from the rear port edge, a part-cylindrical and downwardly convex rear surface having a rear radius of curvature also centered on the symmetry axis. The housing is constructed for movement of air upward through the port.
