(54) Water filtration vacuum cleaner


(57) A water filtration vacuum cleaner (20) that has a modular construction. A motor module (26) fits deep into a central opening of a water tank module (24) so that the center of gravity of the vacuum cleaner (20) is lowered. The water tank module (24) is then placed on top of a trolley module (22), which has a rotatable arm (42). When rotated into a substantially vertical position, the arm (42) secures the water tank module (24) and motor module (26) to the trolley module (22). A vacuum hose (77) connects into the water tank (24) from above. The air path from the hose (77) into the water tank module (24) extends through an upper surface of the water tank module (24) that incorporates the motor module (26). When activated, motor cooling air is drawn in through the bottom of a central opening (36) in the trolley module (22).
