Patent number: 8402600Abstract: A vacuum cleaner nozzle with a nozzle housing, an outlet opening on the housing, a suction opening on a side of the housing facing a surface to be cleaned, at least one roller connected to the housing to support the vacuum cleaner nozzle, and a sealing member on the nozzle. The suction opening communicates with the outlet opening to draw debris through the suction opening when a suction source is connected to the outlet. The roller has an essentially air tight material and rotates such that the roller surface moves towards the suction opening to sweep debris towards the suction opening. The sealing member has a sealing portion in close apposition to at least part of the roller. The sealing portion partly surrounds and substantially restricts airflow across a sealed portion of the roller located essentially opposite the surface being cleaned. The roller also functions as an air barrier.Type: GrantFiled: December 13, 2007Date of Patent: March 26, 2013Assignee: AB ElectroluxInventors: Jonas Beskow, Anders Haegermarck

Publication number: 20100293743Abstract: A vacuum cleaner with a vacuum, a filtering unit, switching means for switching between a vacuum cleaning and filter cleaning modes, and a separating unit. In the vacuum cleaning mode, the vacuum forces a first air stream in a first air stream path through the filtering unit, in a first direction, to filter out dust from the dust laden air stream. In the filter cleaning mode, the vacuum forces a second air stream in a second air stream path through the filtering unit, in a second direction reverse to the first direction, to remove dust from the filtering unit. In the filter cleaning mode, the separating unit is in the air path between the vacuum and the filtering unit to separate dust removed from the filtering unit. In the vacuum cleaning mode, the separating unit is not in an air stream path.Type: ApplicationFiled: August 28, 2008Publication date: November 25, 2010Inventors: Jonas Beskow, Håkan Miefalk, Stefan Jonsson, Anders Haegermarck

Patent number: 7647144Abstract: An obstacle-sensing system for carriers, particularly autonomous carriers such as robot vacuum cleaners, enables the carriers to disengage themselves from any obstacle or obstruction with which they come into physical contact and proceed past the obstacle or obstruction. The obstacle-sensing system is established by constructing a carrier to have front and rear sections which, normally, are in a neutral relationship with respect to one another but which move relative to one another when the front section physically engages an obstacle or obstruction. The relative movement activates a guidance and control system that maneuvers the carrier around the obstacle or obstruction.Type: GrantFiled: February 25, 2002Date of Patent: January 12, 2010Assignee: Aktiebolaget ElectroluxInventor: Anders Haegermarck

Patent number: 7275280Abstract: A carrier, such as an autonomous cleaning apparatus, has a self-adjusting wheel assembly that can move vertically, thereby enabling the carrier to readily pass over a surface. The wheel assembly may include microswitch, which activates a control mechanism for the carrier when a wheel assembly is in a predetermined position along its path of vertical movement. Rollers can be located at the bottom of the carrier to function in cooperation with the wheel assemblies so as to facilitate the ability of the carrier to pass over obstacles. This ability may be enhanced by constructing the bottom of the front portion of the carrier so that it is slanted or inclined upwardly in a direction outward from the bottom of the carrier. A driving wheel may be rotatably attached to a wheel support, and which may also support a power source and a transmission.Type: GrantFiled: February 25, 2002Date of Patent: October 2, 2007Assignee: Aktiebolaget ElectroluxInventors: Anders Haegermarck, Ulrik Danestad, Lars Mennborg
