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, wherein the dust collector arrangement comprises a dust separator, wherein the dust collector arrangement comprises a motorized fan unit for suctioning an air stream through the floor nozzle, wherein the motorized fan unit is arranged so that an air stream suctioned in through the floor nozzle, the suction tube, and the suction hose flows through the motorized fan unit and into the dust separator, wherein the dust collector arrangement has a housing and the motorized fan unit is mounted on or in the housing, wherein the dust separator is mounted in the housing.

The present invention relates to a vacuum cleaner robot comprising a floor nozzle supported on wheels and a dust collection unit, wherein the floor nozzle comprises a driving device for driving at least one of the wheels of the floor nozzle, wherein one of the wheels, a plurality of or all of the wheels of the floor nozzle are omnidirectional wheels, wherein the floor nozzle comprises a base plate with a base surface, which, when the vacuum cleaner robot is in operation, faces the surface to be cleaned, the base plate having provided therein an air flow channel, which extends parallel to the base surface and through which air to be cleaned enters the floor nozzle, and wherein the floor nozzle comprises a rotating means for rotating the air flow channel about an axis perpendicular to the base surface.

A vacuum cleaner including a motor, a suction opening, an exhaust opening, and an air passageway in fluid communication with the suction source and the exhaust opening. The motor receives power from a power cord that enters the lower portion of the main body through a power cord opening. The main body also includes a drain opening, configured to allow egress of any liquid in the main body. The power cord opening is higher than the drain opening. The vacuum also includes a protective tubular frame that surrounds the battery. The tubular frame is energy-absorbing, and is removable and replaceable.

An extension pipe (30) is configured to allow a suction tool (70) to be connected to one end side in a pipe axis direction and a vacuum cleaner main body (10) to be connected to another end. The extension pipe (30) includes a power-receiving portion (36) configured to receive and supply electric power to be fed to a battery (17a) provided to the vacuum cleaner main body (10).

A self-cleaning automatically-stored electrical mop includes a mop rod assembly, a mop head assembly, and a cleaning base assembly used for storing and cleaning the mop head assembly. The mop head assembly is arranged at the lower end of the mop rod assembly and includes a mop head shell which is provided with a rotatable cleaning roller and a motor used for driving the cleaning roller. The cleaning base assembly includes a shell part. A cleaning groove used for cleaning the cleaning roller is formed in the shell part, and a cleaning assembly used for scrubbing the cleaning roller is arranged in the cleaning groove. The shell part is provided with a sewage discharge system used for discharging sewage.

Provided is a robot cleaner including a main body including a suction portion disposed therein, a main wheel for moving the main body, wherein a vertical level of the main wheel varies in a vertical direction with respect to the main body, an auxiliary wheel disposed at a front portion or a rear portion of the main body, wherein a vertical level of the auxiliary wheel is fixed with respect to the main body, and a driving member assembly disposed in the main body, wherein the driving member assembly varies a vertical level of the main body from a floor face while rotating in forward and rearward directions of the main body, wherein the driving member assembly has different hitting radii when rotating forward and rearward.

A device for receiving a suction hose that connects a nozzle of a vacuuming device to a central unit of the vacuuming device. The device is has at least one holding device that can be arranged on the central unit of the vacuuming device, wherein the suction hose is able to be fitted in the at least one holding device such that the hose can be accommodated in a secure and stable manner. This advantageously makes it possible for the user of the vacuuming device to be able to adapt the length of the suction hose as required to the task currently to be performed. Here, the unused part of the suction hose is stored in a particularly secure and stable manner in the device or in cavities of the device that can be formed between the at least one holding device and a rear part. In a second aspect, the invention relates to a vacuuming device having a central unit that is connected to a suction hose having a nozzle.

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.

An obstacle avoidance method for a self-moving robot includes: obtaining and recording, by the self-moving robot, information about an obstacle encountered during traveling, wherein the information about the obstacle includes type information and location information of the obstacle; and receiving, by the self-moving robot, an operation instruction for a specified obstacle, wherein the operation instruction is configured for instructing the self-moving robot, when detecting an obstacle of a same type as the specified obstacle in a region range labeled with the specified obstacle, not to perform an obstacle avoidance operation on the obstacle of the same type.

A method of controlling a mobile robot includes a first basic learning process of generating a first basic map based on environment information acquired in a traveling process, a second basic learning process of generating a second basic map based on environment information acquired in a separate traveling process, and a merging process of merging the first basic map and the second basic map to generate a merged map.
