HOW THE MACHINE WORKS
This machine is constructed to clean carpets.
The head, which pre–soaks the carpet and lifts the
dirt, contains solution dispensing nozzles.
The vacuum picks up the solution into the recovery
tank. The solution passes through the filtration system
– debris and dirt are captured and the solution is
clarified. Solution is forced into the solution tank from
the recovery tank.
