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.

Described is a nozzle (6) for a vacuum cleaner and a vacuum cleaner. The nozzle comprises at least one electrical terminal and an electrical circuit (10) configured to provide identity data about the nozzle via said at least one electrical terminal. Hereby it is enabled to via a wire line connection identify the nozzle in a unit such as the main unit (3) of a vacuum cleaner. This in turn enables correct control of the nozzle from the main unit since the main unit can gain access to important data about the nozzle and thereby provide an improved control of the nozzle.

A robot cleaner that sweeps dust on the floor toward its center and absorbs the dust through a small-area inlet with a strong suction force, by a cleaning tool that integrates functions of side brushes and a main brush into one. The present disclosure also provides a robot cleaner that enables a large-diameter foreign material to be guided to and effectively absorbed through the inlet without interference by a cleaning tool. The robot cleaner includes a main unit including a fan motor and a dust collector and having an inlet arranged on a base to absorb foreign materials, and a cleaning tool arranged in the bottom of the base, extending to a front side of the base from the inlet and guiding a foreign material on a floor to a side of the inlet, wherein the cleaning tool is arranged to be movable by an external force.

A robot cleaner and a method for controlling the same are disclosed, which perform efficient cleaning by controlling a suction force or traveling route of the robot cleaner. The robot cleaner detects load applied to wheels of the robot cleaner so as to increase reliability and accuracy in floor state decision, thereby recognizing a floor state. The robot cleaner recognizes a floor state by combining load applied to wheels of the robot cleaner, load applied to brushes, and acceleration information of the robot cleaner with one another in a complementary manner, thereby increasing accuracy in floor state decision. The robot cleaner includes a traveling portion configured to include a traveling wheel to move a main body, and a wheel motor to provide the traveling wheel with drive power, a cleaning portion configured to include a brush module formed at a lower part of the main body to scatter dust or foreign substances accumulated on a floor on which the main body travels, and a suction module to suction the scattered dust or foreign substances, and a controller configured to determine a state of the floor, and control a suction force of the suction module and a traveling route of the main body according to the determined floor state.

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.

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.

A surface cleaning apparatus includes a supply tank, a fluid dispenser, a brushroll rotatable about an axis, a brushroll motor configured to rotate the brushroll in a forward direction about the axis and a backward direction about the axis, and a controller. The controller executes a scrub mode in which the brushroll is oscillated forward and backwards about the axis to scrub a surface to be cleaned and break up a stubborn stain on the surface.

The present invention discloses a handheld vacuum cleaner for pets, including a body, a charging base, a dust suction port, a cleaning accessory, and the like. A trigger is arranged on the body on a side of the dust suction port, and a driving member is arranged in the cleaning accessory. When the cleaning accessory is inserted into the dust suction port, the driving member can be brought into contact with the trigger, and the driving member can be driven by a pressing operation of the trigger to perform hair removal on the cleaning accessory. With this structure, a user can simultaneously perform grooming and dust suction and remove hair adhering to the cleaning accessory by holding the body with a single hand, which is simpler and more labor-saving in use. Moreover, the internally mounted driving member also makes the entire cleaning accessory compact and aesthetic in appearance. In addition, a dust canister removably mounted to a rear part of the body can be prevented from being occluded, which is convenient for the user to clearly observe an operating condition inside the dust canister during use. In particular, a position of the rear dust canister is separate from a position of the front dust suction port, so that the dust canister can be made larger and longer, and a storage capacity of the dust canister is also increased.

A surface cleaning apparatus includes a supply tank, a fluid dispenser, a brushroll rotatable about an axis, a brushroll motor configured to rotate the brushroll in a forward direction about the axis and a backward direction about the axis, and a controller. The controller executes a scrub mode in which the brushroll is oscillated forward and backwards about the axis to scrub a surface to be cleaned and break up a stubborn stain on the surface.
