ABSTRACT:
A base unit having a vacuum hose and vacuum head attachable thereto includes means for developing a source of low pressure. A detachably attachable housing supporting a conventional vacuum bag is mountable upon the base unit in fluid communication with the low pressure source to form, with the base unit, a dry or vacuum carpet cleaner. The housing is readily replaceable with a first container for ejecting a cleaning solution through jets in the vacuum head into the carpet being cleaned and with a second container in fluid communication with the low pressure source to draw and collect the cleaning solution and the debris from the carpet through the vacuum hose to form, in combination with the base unit, a wet carpet cleaner.
