A remote access duster with a body, a flexible duster cord loop that is configured to be propelled such that part of the loop moves outward from the body while another part moves inward toward the body, and a vacuum source that is configured to draw air over the cord.

A surface cleaning head includes dual rotating agitators (e.g., a leading roller and a brush roll) and a removable cover for covering a top of the agitators and allowing access to the agitators from a top of the surface cleaning head. The dual agitators may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The brush roll may be located in a brush roll chamber and at least partially in an opening to the suction conduit. The leading roller may be positioned adjacent to and in advance of the suction conduit opening such that the leading roller engages debris and moves the debris toward the brush roll and the opening. The leading roller may be removable from the housing and held in place by the removable cover. The cover may be coupled using isolated latching mechanisms.

The invention offers a vacuum cleaner nozzle and vacuum apparatus which can ensure air tightness and prevent vacuum mouth from tilting up. The vacuum cleaner nozzle offered is to be matched with air duct connecting portion of vacuum apparatus, which includes a connecting duct connected to air duct connecting portion; a nozzle main body, having exhaust port which corresponds to air duct connecting portion and is rotatably connected to the other end of connecting duct; a hollow accommodating part which is located in front of exhaust port as well as vacuum mouth which is provided on hollow accommodating part and directed toward surface to be cleaned; a flexible hose, locating between connecting duct and exhaust port with leak-proof fitting; a resilient component butted separately to connecting duct and nozzle main body, for keeping included angle between axis of connecting duct and support surface at predetermined angle.

A cleaner and a method for controlling the same. The cleaner includes a brush module comprising a brush configured to scatter foreign substances on a floor, and a brush motor configured to rotate the brush. The cleaner includes a suction module configured to suction the foreign substances; a sensor configured to detect a load applied to the brush; and a controller configured to control suction force of the suction module based on the load detected by the sensor.

A nozzle includes: a housing having a chamber formed in the housing and a front opening formed on a front side of the housing; a rotation cleaning part accommodated in the chamber and to clean a floor; a partition member provided in the chamber to partition the chamber into two areas and of which at least a portion is in contact with the rotation cleaning part; a driving unit to rotate the rotation cleaning part; and a connection tube connected to the housing and configured to transfer air introduced through the front opening to a dust container of the cleaner, wherein a lower passage formed below the rotation cleaning part and an upper passage formed above the rotation cleaning part are provided in the chamber, and a portion of the partition member is recessed to define the upper passages.

An automatic filter cleaning system, e.g., for cleaning a filter in a vacuum cleaner. The cleaning system has an electrical motor that drives/rotates, directly/indirectly, a piston which directly/indirectly opens a filter cleaning valve. The filter cleaning valve may open for a filter cleaning back flow air stream that thus cleans the filter. The piston is spring loaded and a piston guide ensures that the energy accumulated in the spring and piston is released during the rotation of the piston, thereby shortly opening the filter cleaning valve.

The present disclosure describes techniques for a robotic cleaning device to determine a plan to clean an environment based on types of surfaces in the environment. The plan can include a route to take in the environment and/or one or more configurations to apply to the robotic cleaning device during the route. Determining the plan can include inserting detected surface types into an environmental map of the environment. The environmental map can then be used on future routes such that the robotic cleaning device can know a surface type of a surface before the robotic cleaning device reaches the surface. In some examples, a type of a surface of the environment can be detected by the robotic cleaning device based on optical polarization of light.

A robotic cleaning device having main body, at least one driving wheel to move the robotic cleaning device across a surface to be cleaned, and a brush for removing debris from the surface to be cleaned. The brush is arranged on a protrusion in a front end portion of the main body. The widest part of the main body is located between the protrusion and the opposite sidewall of the main body, and within the front end portion of the main body.
