A cyclonic, dust-collecting unit includes: one or more air swirling members, which swirl(s) air; a dust cap, into which air that has passed through the swirling member(s) flows; and a filter unit, through which air that flows out of the dust cap passes. The filter unit includes: a prefilter; a sound-absorbing member, through which air that has passed through the prefilter flows; and a post filter, through which air that has passed through the sound-absorbing member flows.

A hand vacuum cleaner has a first air treatment stage comprising a first stage air treatment chamber and a first stage longitudinal axis extending between the front and rear ends of the first air treatment stage and a second air treatment stage downstream from the first stage air treatment chamber, the second air treatment stage a second stage air treatment chamber and a second stage dirt collection chamber that is exterior to the second stage air treatment chamber. The second stage dirt collection chamber extends forward of the second stage air treatment chamber. A plane that is transverse to the first stage longitudinal axis extends through the first stage air treatment chamber and the second stage dirt collection chamber, and the first stage air treatment chamber and the second stage dirt collection chamber are concurrently openable.

A dust collecting assembly for a vacuum cleaner includes a dust collecting member and a threaded fitting. The dust collecting member is configured to collect dust and debris. The threaded fitting is disposed in communication with the dust collecting member. The threaded fitting includes a threaded collar configured to be connected to a vacuum cleaner. At least one mounting tab is spaced from the threaded collar. The mounting tab is configured to be received by the vacuum cleaner.

A robot cleaner capable of extending the service life of a filter by including a cyclone unit is provided. The robot cleaner includes a main body including wheels configured to rotate about a rotation axis, a brush device provided in the main body to draw in air containing dust, a first chamber, through which the air drawn in through the brush device is introduced, configured to change a traveling direction of the introduced air, and a second chamber connected to the first chamber and including a dust separator separating dust contained in air, and arranged side by side with the first chamber in a direction in which the rotation axis extends.

A waste collection device including a compartment for receiving pet waste or other waste. The device is attached to the end of a leaf blower, hand vacuum, or other device which provides suction. Accessories may be included which allow universal mounting to most or all types of vacuums and leaf blowers. A removable filter bag may be included for cleaner removal of waste.

A dust removal device includes a suction head and at least one filter element. The at least one filter element is disposed obliquely within the dust removal device such that floating mounting of the suction head is maintained by automatic, vacuum-induced suction on the at least one filter element. A method for changing a filter element in a dust removal device includes replacing a filter element from above.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

A vacuum cleaner assembly configured to be mounted in a vehicle. The vacuum cleaner assembly includes a vacuum module and a collector module configured to collect debris and operatively coupled to the vacuum module. The collector module includes a canister assembly with an intake port, an output port, and a flapper valve coupled to the intake port. An elbow assembly couples the vacuum module to the collector module and includes an intake end attached to the output port of the canister assembly. The intake end has a foam section disposed on a grill insert. Upon removal of the canister assembly from the collector module, the flapper valve moves to a closed position over the intake port of the canister assembly to keep debris contained in the canister assembly, and the grill insert and the foam section remain in place in the intake end of the elbow assembly.

A surface cleaning apparatus has a fluid distribution system for storing and delivering fluid to a surface to be cleaned, and includes a steam nozzle in fluid communication with a steam generator. A pad mounting plate is adapted to mount a cleaning pad to the apparatus, and has a steam orifice in fluid communication with the steam nozzle. A flexible seal is provided between the steam nozzle and the pad mounting plate to seals a space between the steam nozzle and the steam orifice to prevent steam leaks.

An evacuation station for a mobile floor cleaning robot comprises a housing and an air treatment assembly removably mountable to the housing. The air treatment assembly is provided on a first lateral housing end. The first lateral housing end is provided with a housing air inlet that is downstream of the air treatment assembly air outlet whereby the air treatment assembly air outlet faces the housing air inlet.
