Abstract
A cleaning and extracting unit which includes a housing comprising upper and lower housing sections removably attached to each other. When attached to each other, the lower and upper housing sections collectively define a pair of vacuum pump chambers and a fluid pump chamber. The unit may be provided with one vacuum pump which is received into one of the vacuum pump chambers, or a pair of vacuum pumps which are connected to each other in series and received into respective ones of the vacuum pump chambers. The unit is also provided with a fluid pump which is received into the fluid pump chamber, as well as a heater which is received into a heater chamber defined by the lower housing section. The housing is sized and configured such that the vacuum pump(s) is/are maintained in the vacuum pump chamber(s) and the fluid pump is maintained in the fluid pump chamber by the compressive pressure exerted against the vacuum pump(s) and the fluid pump by the upper housing section when attached to the lower housing section.
