Abstract
A vacuum cleaner capable of collecting wet or dry media includes a hose having an inlet end and an outlet end that is coupled to the vacuum cleaner. A motor is supported by a portion of the vacuum cleaner and applies a vacuum to the outlet end of the vacuum hose. A media inlet is positioned near the inlet end of the vacuum hose. An air intake for admitting air into the vacuum hose is provided near the media inlet. The air intake can be adapted to receive a detachable separate device in order to provide an air intake that is remotely positioned from the media inlet. Alternatively, the air intake can be provided on an attachment to or an integral part of the vacuum hose for providing the air intake at a remote distance from the media inlet. A distal end of the vacuum hose is immersed in a liquid to be collected so that the media inlet is immersed in the liquid and so that the air intake is exposed to a source of air. A vacuum is applied to the vacuum hose to collect the liquid through the media inlet while air is simultaneously drawn via the air intake into the vacuum hose and mixed with the collected liquid to increase the liquid lift height capability of the vacuum cleaner.
