ABSTRACT:
A water/air separating mechanism receives dirty water, and separates the air from the dirty water before discharging the air. The mechanism includes a housing in which there is disposed a motor which sucks the dirty water and air along a passage which includes an interruption located above a water chamber. The interruption includes a water outlet spaced horizontally from an air inlet. Water leaving the outlet gravitates into the water chamber, and the air travels to the air inlet. That air passes through the motor and then travels through a zig-zag passage before being discharged from the body. A floating valve in the water chamber is arranged to close the air inlet when the water reaches a certain level. A wave dissipation device in the chamber resists the creation of waves in the chamber.
