ABSTRACT:
A liquid bath vacuum cleaner includes a housing having an assembly for cleaning air. A cap assembly is operably connected to the housing. An inner canister is positioned within the cap assembly. A motor is mounted within the canister for rotating the assembly for cleaning air. The cap assembly includes an inlet for enabling ingress of cooling air into the cap assembly and an outlet for enabling egress of cooling air from the cap assembly. A motor cooling fan is connected to the motor for drawing cooling air through the inlet and for exhausting the cooling air radially from the motor cooling fan to cool the motor and exhaust the cooling air through the outlet.
