An electric blower includes a motor unit, a shaft, a centrifugal impeller, a fan cover, a motor unit case, and a bracket located away from centrifugal impeller and toward motor unit in a direction in which a central axis of the shaft extends. The bracket includes a first portion located outward of the vent in a radial direction, and a second portion located outward of the first portion and outward of an outer circumference of the motor unit case in the radial direction. A first airflow passage and a second airflow passage are formed in the bracket, the first and second airflow passages communicate with an airflow passage formed by the centrifugal impeller and the fan cover.

A floor treatment device may include a body portion comprising one or more pumps, one or more spray outlets, and one or more reservoir receptacles configured to receive one or more reservoirs. The one or more pumps are operable to be activated and direct liquids to the spray outlets. The device may include swappable heads, each comprising a body connector configured to mate with a head connector of the body portion. In an embodiment, the head connector may include a sensor system and a controller communicatively connected to the sensor system. When one of swappable heads is connected to the body portion, the sensor system is configured to detect the identity of the swappable heads connected, and the controller is configured to selectively activate, based on the identity of the swappable heads, at least one of the one or more pumps.

The invention relates to a floor vacuum cleaner comprising a dust collector arrangement mounted on rollers and/or runners, a suction hose, a suction tube and a floor nozzle, wherein the floor nozzle is fluidically connected to the dust collector arrangement via the suction tube and the suction hose, also comprising a motorized fan unit for suctioning an air stream through the floor nozzle, wherein the motorized fan unit is arranged between the floor nozzle and the suction tube such that an air stream suctioned in through the floor nozzle flows through the motorized fan unit and into the suction tube.

The present invention relates to an autonomously operable vacuum cleaner that has a modular design. The vacuum cleaner in this respect comprises a cleaning head module as well as a separate canister module. The cleaning head module and the canister module are in this respect connected to one another via a hose so that dust sucked in via the cleaning head module can be conveyed into the canister module.

A hand vacuum cleaner with a finger grip area that is provided between a forward side of the handle and a rear side of the main body, and wherein the suction motor is positioned between the cyclone and the finger grip area and an axis that extends between the front of the cyclone and the handle extends through the suction motor.

A HEPA-qualified coating removal system, coating removal tool, and method is disclosed. The HEPA-qualified coating removal system comprises a HEPA-vacuum coupled to a coating removal tool via a vacuum line. A method of using the HEPA-qualified coating removal system includes, but is not limited to, the steps of the user putting on appropriate protective equipment, connecting the vacuum line of the HEPA-vacuum to an outlet of the coating removal tool, activating the HEPA-vacuum, using scraping motion of coating removal tool to strip a surface and the resulting loose debris being removed by suction force from the environment, deactivating the HEPA-vacuum, and disposing of the debris collected in the HEPA vacuum.

A nozzle arrangement faces a surface to be cleaned includes a first suction body and a second suction body located at a distance relative to each other. The nozzle arrangement further includes a level setting mechanism that puts the first suction body and the second suction body at different overall levels relative to the surface in a normal, operational orientation of the nozzle arrangement on the surface. In this way, cleaning performance of the nozzle arrangement can be improved. Additionally, or alternatively, it is possible to have a suction enhancing mechanism for at least partially closing at least one of the first suction body and the second suction body to one of the surface and an internal air conduit of the nozzle arrangement.

Systems and methods for providing a vacuum cleaner with sliding vacuum head assembly. The vacuum head assembly comprises, for example, a vacuum motor, a dust bin, and a fan. The vacuum clean is configured for cleaning high and low surfaces based on a position of the vacuum head assembly along the vacuum tube.

A cleaner head for a cleaning appliance including a housing having a front side, a rear side, and first and second sides which extend between the front side and the rear side, the housing further including a floor facing surface which extends between the front side, rear side and first and second sides which, in use, faces a surface to be cleaned. A floor engaging device is connected to the floor facing surface of the housing and which extends laterally between the first and second sides of the housing, said floor engaging device including a first portion for absorbing liquid from a surface to be cleaned; and a second portion positioned closer to either a front side or a rear side of the housing, said second portion being relatively stiff compared to the first portion.
