Wet or wet/dry vacuum cleaners are a specialized form of cylinder/drum models that can be used to clean up wet or liquid spills. They are generally designed to be used both indoors and outdoors and to accommodate both wet and dry debris; some are also equipped with an exhaust port or detachable blower for reversing the airflow, a useful function for everything from clearing a clogged hose to blowing dust into a corner for easy collection.

Shop vacs are able to collect large, bulky or otherwise inconvenient material that would damage or foul household vacuum cleaners, like sawdust, [[swarf]], and liquids.<ref name="sfgate-shopvac">{{cite web | url=https://www.weekand.com/home-garden/article/how-a-shop-vac-works-18070290.php | title=How a Shop Vac Works | date=18 September 2009 }}</ref>

They use wide hoses, which open directly into the collection chamber (usually a bucket-like cylinder constituting the body of the vacuum). As the airstream enters the larger volume, its flow slows down, allowing the material to drop into the chamber before air is sucked out through the filter and to the vacuum's exhaust.<ref name="sfgate-shopvac"/>

Shop vacs' performance can be evaluated by a number of metrics. Commonly used ones include the motor's rating (using power measurements like watts or [[horsepower]]), the vacuum's ability to develop suction (using pressure measurements like [[inches of water]]), and total airflow through the system (using volume rate measurements like [[cubic feet per minute]]).<ref name="sfgate-shopvac"/>

Related to the wet vacuum is the extraction vacuum cleaner used mainly in [[hot water extraction]], a method of cleaning hard-to-move pieces of fabric like carpets. These machines are able to spray hot soapy water and then suck it back out of the fabric, removing dirt in the process.

Wet vacuum cleaners have been modified by end users, adding an internally-mounted [[sump pump]] for continuous removal of liquids without having to stop to empty the tank.<ref name="farmshow">{{cite book|title=Encyclopedia of Made it Myself Ideas|volume=4|publisher=Farm Show|location=Lakeville, Minnesota|year=2019|page=19|first=Harry|last=Schwartz}}</ref>{{Better source needed|reason=Citation is a HOW-TO publication, citation(s) may need to be quoted inline showing this is an observation of widespread use, not single contributors invention.|date=June 2023}}
