    Abstract: A vacuum cleaner assembly configured to be mounted in a vehicle. The vacuum cleaner assembly includes a vacuum module and a collector module configured to collect debris and operatively coupled to the vacuum module. The collector module includes a canister assembly with an intake port, an output port, and a flapper valve coupled to the intake port. An elbow assembly couples the vacuum module to the collector module and includes an intake end attached to the output port of the canister assembly. The intake end has a foam section disposed on a grill insert. Upon removal of the canister assembly from the collector module, the flapper valve moves to a closed position over the intake port of the canister assembly to keep debris contained in the canister assembly, and the grill insert and the foam section remain in place in the intake end of the elbow assembly.

    Abstract: A vacuum cleaner includes a body having a space that allows air to flow therethrough. The vacuum cleaner also includes a suction inlet configured to introduce the air into the body. Further, the vacuum cleaner includes a suction motor provided in the body. The vacuum cleaner includes a dust separation module provided in the body. The dust separation module is arranged between the suction inlet and the suction motor. The dust separation module separates foreign substances from the air. The vacuum cleaner includes an exhaust module that discharges the air passing through the suction motor from the body. The exhaust module includes an exhaust filter comprising a photocatalyst. Further, the vacuum cleaner includes a lighting module that radiates light toward the exhaust filter. The vacuum cleaner includes a battery supplying electrical energy for the operation of the vacuum cleaner and a controller configured that controls operations of the vacuum cleaner.

    Abstract: A mobile cleaning robot includes a removable filter unit configured to receive a supply airflow generated by a blower and to filter debris from the supply airflow, a filter seat, a filter access opening, a filter access door, and a filter presence system. The filter access door is pivotable between a closed position, wherein the filter access door covers the filter access opening, and an open position, wherein the filter access door is displaced from the filter access opening to permit access to the filter seat. The filter presence system is configured to: permit the filter access door to move from the open position into the closed position when the filter unit is disposed in the filter seat; and prevent the filter access door from being moved into the closed position when the filter unit is not disposed in the filter seat. The filter presence system includes a lift arm movable between an extended position and a retracted position. When the filter access door is open, the lift arm assumes the extended position to receive the filter unit in the filter seat. Moving the filter access door from the open position into the closed position when the filter unit is disposed in the filter seat causes the lift arm to move to the retracted position.
