Embodiments provide a plurality of personalized, user selectable styles. Each style is determined by a combination of dimensions. Each style, except the default balanced style, prioritizes one of the dimensions over the other cleaning dimensions. In one embodiment, the styles are cleaning styles and the cleaning dimensions are cleaning time, coverage and obstacle avoidance. The cleaning styles are gentle, fast, thorough and balanced. The gentle style protects expensive furniture, with obstacle avoidance prioritized over cleaning time and coverage. The fast style cleans quickly, prioritizing cleaning time over coverage and obstacle avoidance. The thorough style prioritizes coverage over cleaning time and obstacle avoidance. The balanced style prioritizes all three cleaning dimensions substantially the same. The prioritization is achieved through adjustments to the autonomous robot navigation. User selection of a style can be achieved directly or automatically based on various mechanisms, such as user history.

The present invention relates to a vacuum cleaner. The vacuum cleaner of the present invention comprises: a cleaner body having a suction motor for generating suctioning force, and running in operating mode and charging mode; a suctioning part communicating with the cleaner body, for suctioning air and dust; a battery assembly capable of supplying power to the suction motor and having a plurality of battery packs; a controller for controlling the operation of the suction motor; a current regulating unit for regulating the current applied to the suction motor in a state in which the plurality of battery packs are serially connected; a first switching mechanism for serially connecting the plurality of battery packs; and a second switching mechanism for parallelly connecting the plurality of battery packs.

A movable device includes: at least one lift generating unit for generating a pressure difference between opposite sides thereof to generate a lift force; a movable device body connected to the lift generating unit to be movable by the lift force generated by the lift generating unit; and at least one supply duct, the number of which corresponds to the number of the lift generating unit. One end of the supply duct is disposed on one side of the lift generating unit and, when the lift generating unit operates, fluid is suctioned through the other end of the supply duct to be supplied into the lift generating unit.

Disclosed is a cleaner. The cleaner includes a cleaner body, a suction nozzle configured to suck dust on a floor surface, and a suction hose configured to transfer the dust, transferred from the suction nozzle, to the cleaner body. The cleaner body includes a driving driver or motor moving the cleaner body, a depth sensor configured to obtain image information about an object near the cleaner body, and a processor configured to extract a foot sole region of a person, based on the obtained image information, obtain a moving point of the cleaner body, based on the extracted foot sole region, and control the driving driver to move the cleaner body to the obtained moving point.

A self-propelled cleaning device has a surface cleaning system for cleaning a surface to be cleaned. In order to also be able to clean an above-floor surface, the cleaning device also has an above-floor cleaning element for mechanically cleaning an above-floor surface offset in terms of height relative to the surface. The above-floor cleaning element can be rotated and/or pivoted around a rotational axis, and at least one partial cleaning area of the above-floor cleaning element has a difference in height of roughly 3 cm or more relative to a lowermost standing surface of the cleaning device by comparison to a usual orientation of the cleaning device for a cleaning operation.

A blower device includes a motor that includes a shaft centered around a central axis extending in a vertical direction, a stator surrounding the shaft, and a housing holding the stator, an impeller that is connected to an upper side of the shaft, an impeller housing that accommodates the impeller and includes an intake port, and an exhaust port that is positioned below a circumferential edge portion of the impeller housing. The exhaust port is positioned above the housing and opens downwards along a circumferential direction.

A blower includes a rotor including a shaft disposed along a central vertical axis, a stator positioned radially outward of the rotor, a tubular housing accommodating the rotor and stator, and an impeller attached to the shaft at a position above the stator. The stator includes an annular core back portion, tooth portions extending radially inwards from the core back portion, coils wound around the tooth portions, and at least two walls circumferentially arranged with a gap therebetween. In a radial direction, radially outer ends of the walls constitute an outer opening of the gap, and radially inner ends constitute an inner opening thereof. The housing includes a first through-hole radially penetrates the housing and is connected to the outer opening. At least one of the walls arranged adjacently in the circumferential direction includes a side surface facing the gap and inclined with respect to the radial direction.
