A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

Provided is a robot including main and peripheral brushes; a first actuator; a first sensor; one or more processors; and memory storing instructions that when executed by the one or more processors effectuate operations including: determining a first location of the robot in a working environment; obtaining, with the first sensor or another sensor, first data indicative of an environmental characteristic of the first location; adjusting a first operational parameter of the first actuator based on the sensed first data to cause the first operational parameter to be in a first adjusted state while the robot is at the first location; and forming or updating a debris map of the working environment based on data output by the first sensor or the another sensor configured to collect data indicative of an existence of debris on a floor of the working environment over at least one cleaning session.

A vacuum cleaner is disclosed. The vacuum cleaner according to embodiments of the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a housing, a button, a rotating brush, and a detachable cover. The housing includes an insertion hole. The button includes a first protrusion. The detachable cover includes a cover body and a slider. The cover body includes an insertion member, a second protrusion, and a rail. The rotating brush is rotatably mounted to the slider. The slider is mounted on the rail so as to be movable in a first direction. The insertion member is inserted into the insertion hole in the first direction. As the button is moved, the first protrusion is selectively positioned in a movement path in the first direction of the second protrusion.

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.

The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

The present invention relates to a robot cleaner. The robot cleaner comprises: a cleaner body equipped with a driving wheel; and a cleaning nozzle mounted inside a downwardly open opening portion in a lower portion of the cleaner body so as to be able to ascend and descend. The cleaning nozzle can be supported by a plurality of ascending/descending guides and a plurality of auxiliary ascending/descending guides so that the cleaning nozzle can ascend and descend relative to the cleaner body according to changes in the height of a cleaning surface on which the cleaner body travels. Accordingly, the cleaning to nozzle rises upon being pressed by a compressible floor such as a carpet, thus solving the problem of the cleaning nozzle catching on the cleaning surface. Therefore, travel performance can be improved, and the load on a brush driving part can be reduced.

A cleaner includes: a cleaner body having therein a module mounting portion; a rotation driving portion provided at one side of the module mounting portion; and a cleaning module detachably mounted to the module mounting portion through one side of the cleaner body, wherein the cleaning module includes: a holder linearly inserted into or withdrawn from the module mounting portion in a side direction of the cleaner body; and a cleaning member supported by the holder so as to be inserted or withdrawn into or from the module mounting portion, together with the holder when the holder is inserted thereinto or withdrawn therefrom, and the cleaning member rotated by a driving force provided from the rotation driving portion.

An electric vacuum cleaning apparatus including an autonomous robotic vacuum cleaner that autonomously moves between surfaces to be cleaned and collects dust and a station fluidly connectable to the autonomous robotic vacuum cleaner. The autonomous robotic vacuum cleaner includes: a container body accumulating collected dust, the container body including: a bottom wall including a disposal port; and a disposal lid opening and closing the disposal port. The station unit includes: a dust transfer pipe connected to the disposal port; a secondary dust container accumulating dust; and a secondary electric blower that generates negative suction pressure in the dust transfer pipe via the secondary dust container. At least one irregularly shaped ventilation groove that causes air to flow below the dust within the container body by the negative pressure generated by the secondary electric blower is provided to the inner surface of the bottom wall of the container body.

A vacuum cleaner includes: a vacuum motor; a first sensor configured to generate first sensor signals based on sensed motion and orientation of the vacuum cleaner; a cleaner head comprising an agitator; one or more diagnostic sensors configured to generate second sensor signals based on sensed parameters of the cleaner head; and a controller configured to: process the generated first and second sensor signals to determine a type of surface on which the vacuum cleaner is being operated; and control the power of the vacuum motor in dependence on the determined type of surface.
