A vacuum cleaner assembly and vacuum cleaner with a vacuum cleaner assembly, including a suction device with a basic body with a first end with at least one suction inlet for connection with a suction tube and/or suction hose of the vacuum cleaner. Furthermore, the basic body divides at a second end into two substantially tubular suction ducts, each having a suction intake, wherein one suction arm each is associated with the suction intakes, and wherein the suction arms are provided pivotable about the associated suction duct.

The present invention relates to a flow structure of a companion animal duct collector, and more particularly, to a flow structure of a companion animal duct collector including a main body part that includes an inner case through which air or hair of a companion animal is introduced and an outer case surrounding front and rear surfaces of the inner case and discharging air moving through the inner case to the outside, a suction fan unit that has a motor fan inside the inner case, and a suction grill unit that includes a suction grill coupled to one side of the outer case and sucking in external air by the operation of the suction fan unit, whereby air is collected to the other side of the main body part to form a low pressure part, thereby forming an additional air flow by the operation of the suction fan unit.

A vacuum cleaning system comprises a vacuum cleaner and a docking station. The docking station comprises a dirt storage chamber and an interface configured to mate with a dirt bin of the vacuum cleaner such that dirt expelled from the dirt bin through a bin opening is ejected into the dirt storage chamber of the docking station. A vacuum generator evacuates air from the dirt storage chamber when the vacuum cleaner is docked. In a dirt bin emptying mode, the system operates the vacuum generator to generate a partial vacuum in the dirt storage chamber and, opens a dirt bin door once a sufficient negative pressure level has been generated, and operates an air valve arrangement to admit a pulse of air into the dirt bin to eject dirt from the dirt bin through the bin opening and into the dirt storage chamber.

A head for a suction device is disclosed. The head. comprising: at least one suction inlet, configured to provide suction in a first direction; at least one suction tube, wherein each suction tube is in fluid connection to each suction inlet, wherein each suction tube is further connectable to a pump; a plurality of radial outlets, configured to provide air in a radial direction, wherein the radial outlets are in fluid connection with at least one chamber connectable to at least one blower, and at least one forward outlet configured to provide air in a second direction, wherein each forward outlet is in fluid connection to the at least one chamber connectable to the at least one blower. The suction device may include a holder for holding a sensor. The holder may be located in the suction tube.

A movable platform control method and device, a movable platform, a control system, and a computer-readable storage medium are provided. The method comprises: determining semantic information of different objects located on a movement path; determining different safe execution distances for the different objects based on the semantic information of the different objects; and controlling the movable platform to execute a cleaning task and/or obstacle avoidance task according to the different safe execution distances of the different objects, where the semantic information of the different objects allows differentiation between obstacles and objects to be cleaned.

A vacuum cleaner nozzle includes a housing with, formed on an underside of the housing and extending in a transverse direction, a suction orifice that is bounded by what in a working direction aligned perpendicular to the transverse direction is a front suction-orifice edge and by what in the working direction is a rear suction-orifice edge, with a suction duct disposed in the housing and adjoining the suction orifice, with a suction port extension, which is also fluidically in communication with the suction duct and is disposed, relative to the working direction, on a rear side of the housing. The vacuum cleaner nozzle further includes a secondary air aperture disposed in front of the suction orifice and fluidically in communication with the suction duct. The secondary air aperture is at least partly covered by a flexible textile valve element.

A vacuum cleaner comprising: a housing; a fan; a dirt collection chamber having an opening for emptying dirt from the dirt collection chamber; and a cover movable between a closed position, in which the cover seals the opening, and an open position, wherein the vacuum cleaner is configured to operate: in a suction mode in which the fan generates a suction airflow from an air inlet to an air outlet; and in a blow mode in which the fan generates a blowing airflow from the air outlet to the opening when cover is in the open position.

A mobile cleaning robot can include a body movable within an environment and a debris bin located at least partially within the body. The robot can include a cleaning assembly connected to the body, where the cleaning assembly includes a first debris port connected to the debris bin and a second debris port connected to the debris bin.

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.

A method to control an input power of a motor of an air-moving device that includes performing a measurement process to determine a first value of an operating parameter of the motor. The operating parameter is an operating pressure of the motor or an airflow rate through the motor. The method includes performing a determination process to determine a value of the inlet restriction of the air-moving device, based on the first value of the operating parameter of the motor and a first pre-determined relationship between values of the operating parameter of the motor and values of an inlet restriction of the air-moving device. The method also includes controlling, based on the determined value of the inlet restriction, the input power of the motor.
