(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). |
