摘要： A system of robotic cleaning devices and a method of a master robotic cleaning device of controlling at least one slave robotic cleaning device. The method performed by a master robotic cleaning device of controlling at least one slave robotic cleaning device includes detecting obstacles, deriving positional data from the detection of obstacles, positioning the master robotic cleaning device with respect to the detected obstacles from the derived positional data, controlling movement of the master robotic cleaning device based on the positional data, and submitting commands to the at least one slave robotic cleaning device to control a cleaning operation of said at least one slave robotic cleaning device, the commands being based on the derived positional data, wherein the cleaning operation of the slave robotic cleaning device is controlled as indicated by the submitted commands.

摘要： A vacuum cleaner separation system having: a cyclone tube having a cyclone chamber and an inner wall having a substantially cylindrical appearance defining a center axis; an inlet channel offset with respect to the center axis for receiving dust laden air; a dust outlet for discharging dust from the cyclone tube; an air outlet for discharging air from the cyclone tube; and a helical member arranged within the cyclone tube in an opposite region of the cyclone tube with respect to the air outlet. The helical member defines or partly defines a helical passage around the center axis from the inlet channel to the cyclone chamber for generating a centrifugal flow in the cyclone chamber. The helical passage has a substantially constant cross sectional area and the helical passage is rotated 360° or less than 360° around the center axis.

摘要： A robotic cleaning device configured to detect objects as the robotic cleaning device moves over a surface to be cleaned. The robotic cleaning device has a first light source configured to produce a close range wide light beam in front of the robotic cleaning device, a second light source configured to produce a long range vertically-narrow light beam in front of the robotic cleaning device, and an array sensor configured to detect light reflected from one or more of the light sources to detect illuminated objects from which said light is reflected.

摘要： The invention relates to a stick vacuum cleaner comprising a handheld vacuum cleaner adapted to be docked to a stick. When the handheld vacuum cleaner is docked to the stick an air path is formed connecting an air outlet of the handheld vacuum cleaner with an air outlet provided in the stick. In the air path or outside the air outlet provided in the stick, a filter is provided.

摘要： A robotic cleaning device and a method at the robotic cleaning device of performing cliff detection along a surface over which the robotic cleaning device moves. The method includes illuminating the surface with at least one light source, capturing an image of the surface, detecting at least one illuminated section in the captured image, and determining distance to objects in the at least one illuminated section of the captured image. The method further comprises comparing at least two of the determined distances and detecting an object in the captured image as a cliff when cliff when a relation between the at least two compared determined distances complies with a predetermined increase criterion.

摘要： A vacuum cleaner dust container having a dust bag, made of an air permeable material, and a connector plate, surrounding an opening in the dust bag. The connector plate is configured by the connector plate being slid into a holder of a vacuum cleaner to correctly position the opening therein. The connector plate has a central portion surrounding the opening, and an extending portion projecting from the central portion. The extending portion has a lower bending stiffness than the central portion about an axis perpendicular to the direction in which it is inserted. Thereby extending portion can be bent out of the plane of the central portion and into a curvature without bending the central portion, which facilitates fitting the connector plate in a vacuum cleaner canister with curved inner walls.

摘要： A robotic vacuum cleaner having a nozzle inlet facing a surface to be cleaned, and a rotatable side brush. The rotatable side brush has bristles extending substantially in parallel with the surface to be cleaned, and the nozzle inlet includes a frame structure forming an opening, the opening being arranged in fluid communication with a debris receptacle. The bristles extend over a side portion of the nozzle inlet. The frame structure has a base portion extending substantially in parallel with the surface to be cleaned. The base portion extends at a first level. The frame structure at the side portion extends substantially in parallel with the surface to be cleaned at a second level. The first level is arranged closer to the surface to be cleaned than the second level.
