The plurality of discharge conduits have a plurality of respective outlets at different locations within the interior of the vacuum container for discharging collected material into different collection receptacles. The filter is sandwiched between the intermediate wall and the plurality of discharge conduits.

The disclosure provides a debris bin assembly, a cleaning robot and a cleaning robot system, the debris bin assembly includes a debris bin housing, a filter assembly, and a flow guide plate, the debris bin housing includes a top portion and a bottom portion disposed opposite to the top portion, and a side housing surrounding the top portion and the bottom portion, the top portion, the bottom portion and the side housing are enclosed to form an inner cavity, the top portion of the debris bin housing is provided with an air exhaust channel communicating with the inner cavity and an air outlet communicating with the air exhaust channel, the side housing is provided with an air inlet communicating with the inner cavity, the air inlet inclines towards a side where the top portion is located, the filter assembly is disposed in the air exhaust channel of the top portion, the flow guide plate is located in the inner cavity and is disposed opposite to the air inlet, the flow guide plate extends from the top portion to the bottom portion and is configured for intercepting, decelerating and laterally guiding air flow entering from the air inlet, so as to decelerate and laterally guide air flow carrying debris, which avoids debris directly impacting a filter screen at a high speed and attaching to it, and consequently, a problem that the filter screen is easily blocked is solved.

A cleaner includes: a main body that forms an external shape; a dust container that is separably combined with the main body and stores dust separated from air; a dust container cover that is configured to open and close the dust container; a handle unit that is disposed behind the dust container; and an operating member that is configured to provide operation force to the dust container cover by moving in a first direction and to release a holding mechanism for preventing separation of the dust container from the main body by moving in a second direction opposite to the first direction.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

A surface treatment apparatus may include a surface cleaning head having an agitator, an agitator motor configured to cause the agitator to rotate, and a controller. The controller can be configured to determine a surface type corresponding to a surface to be cleaned and to transition the surface treatment apparatus between a first operational mode and a second operational mode based, at least in part, on the determined surface type. Determining the surface type may include measuring a plurality values corresponding to a current draw of the agitator motor over a predetermined time window at a predetermined time interval, determining an average corresponding to the measured values, comparing the average to at least a first threshold, and transitioning the surface treatment apparatus between the operational modes based, at least in part, on the comparison.

A cleaner comprises a housing having a dust collection chamber formed in the housing and configured to open and close, a main body movable relative to the housing between a first position whereby the main body closes the dust collection chamber and a second position whereby the main body opens the dust collection chamber, and a motor filter mountable to and demountable from the main body, wherein the main body includes a fan motor unit to generate a suction force, and a shutter device mountable into the main body and configured to open and close a flow path between the motor filter and the fan motor unit.

The present application discloses dust boxes, dust box assemblies and cleaning devices, wherein the dust box assembly includes a dust box and at least two fans. The dust box is formed with a holding cavity, a dust suction port and at least two air outlets, the dust suction port is connected to the holding cavity, the at least two air outlets are connected to the holding cavity. At least two fans are provided corresponding to at least two air outlets for creating an airflow that passes through the dust suction port, the holding chamber and the air outlet in sequence.

A floor cleaner includes a recovery tank including an inflow path allowing liquid-laden air to enter the recovery tank, an outflow path allowing air to exit the recovery tank; and a chamber for storing liquid. The chamber includes an inlet, a separator that separates liquid from the liquid-laden air, an air outlet, and a float. The float includes a base and a valve with an indicator. The float is moveable between a first position and a second position. In the first position the valve is spaced away from the air outlet and air is allowed to exit the chamber. In the second position the valve is adjacent the outlet and impedes air from exiting the chamber. In the second position the indicator is visible when the chamber is full.

A docking station for a robotic vacuum cleaner has a pneumatic transfer mechanism that is used to direct air to the robotic vacuum cleaner to thereby transfer dirt from the robotic vacuum cleaner to a docking station.

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.
