A surface cleaning apparatus is disclosed having a forward portion and a rearward portion. The forward portion has a dirty air inlet, a front side, a rear side and a forward bridging section, the forward bridging section having a rearwardly extending air flow passage that is downstream from the dirty air inlet. The rearward portion positioned rearward of the forward portion, the rearward portion comprising a front side, a rearward side, a rearward bridging section, a lower planar surface, an upper surface and an up flow duct, the rearward bridging section being spaced rearward of the front side of the rearward portion. The rear side of the forward portion is spaced from and faces the front side of the rearward portion and the forward bridging section is connected to the rearward bridging section.

A cordless wet and dry stick vacuum cleaner system has a portable power module, which includes an airflow generator, a battery, and control circuitry. This may be used with either a wet dirt management system and a wet vacuum nozzle or it may be used with a dry dirt management system and a dry vacuum nozzle. The shared power module enables power savings, whereas the other parts remain optimized for their specific function.

A cleaner holder comprises a base, a stand coupled to the base and extending upward from the base, a support body coupled to an upper portion of the stand and configured to support a cleaner, and a cleaning module support coupled to the stand and configured to support a cleaning module of the cleaner. The cleaning module may be detachably coupled to an extension tube of the cleaner.

A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) 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 leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

According to an embodiment of the present disclosure, provided is a cleaner which comprises: a main body having a cylindrical shape; a cyclone unit which is provided inside the main body so as to separate dust from air suctioned into the main body; an extension duct which communicates with the cyclone part and extends from the main body; a suction nozzle which is coupled to the extension duct and suctions dust; a first battery unit which extends from the main body and supplies electric power so that the cyclone unit can suction air; and a second battery unit which supplies electric power to the cyclone unit and is slidably coupled to the extension duct. According to an embodiment of the present disclosure, the usage time of the cleaner can be increased, and the fatigue that a user feels can be minimized even when the usage time is increased.

A vacuum cleaner including a cleaner body including a motor configured to generate a suction force and a foreign substance collection chamber; and a suction head connected to the cleaner body. The suction head may include a drum brush, a one-way roller disposed in front of the drum brush, and a housing having a suction port. The drum brush and the one-way roller may be configured so that, when the suction head is moving forward on a surface to be cleaned, the drum brush and the one-way roller rotate so that foreign substances on the surface are suctioned by the suction force into the housing through the suction port to be guided to the foreign substance collection chamber, and when the suction head is moving rearward on the surface, rotation of the one-way roller is restricted to prevent the foreign substances suctioned into the housing from being discharged outside of the housing of the suction head through the suction port.

A cleaner includes a main body and a suction head connected to the main body to suck foreign objects into the main body therethrough, the suction head including a housing including a suction port, and a drum module disposed in the housing, and to be rotated to scatter the foreign objects to be sucked through the suction port so that the scattered foreign objects are drawn into the housing through the suction port, and the drum module including a drum body, a first blade coupled to outer circumference of the drum body, a second blade separated from the first blade in a circumferential direction of the drum body and having a mass greater than a mass of the first blade, and a mass compensation member arranged on the outer circumference of the drum body to compensate for a difference in mass between the first blade and the second blade.

Provided is a cleaner system, according to one embodiment of the present disclosure, which comprises a terminal and a cleaner provided to be capable of wireless communication with the terminal. The cleaner comprises: a main body; a cleaning unit provided in the main body; a communication unit that wirelessly communicates with an external terminal; a control unit for processing information on the cleaner; and a battery for providing power, wherein the terminal visually provides information transmitted from the cleaner to a user. According to embodiments of the present disclosure, it is possible to enable a user to easily grasp information on the cleaner even if the user does not pay great attention to the cleaner, and to catch the user's attention by means of an alarm.

A vacuum cleaner comprises a housing having a longitudinal axis. A motor-fan assembly is mounted in the housing and arranged to generate an airflow along an airflow path from a dirty air inlet to an air exhaust. A retractable nozzle defines the dirty air inlet and is moveably mounted on the housing. At least a portion of the retractable nozzle is arranged to move between a retracted configuration within the housing and a deployed configuration outside the housing. The portion of the retractable nozzle in the retracted configuration is aligned in a direction along the longitudinal axis and the portion of the retractable nozzle in the deployed configuration is aligned in a direction across the longitudinal axis.
