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.
