Abstract
A coin operated vacuum is made with two housings, one for mounting the coin mechanism and the vacuum motor and blower, and the other comprising the debris collection barrel and filter. The two housings are made so that they are virtually tamper-proof, and are joined together as a unit, with the housing mounting the operating components comprising a tower that is securely fixed from the inside to a support base, and which is constructed to provide ready axis to the internal operating components by removal of a secure draw bolt type lock. The debris collection bin has a removable top which can be removed for access to the interior for removal and replacing of a plastic bag that collects the heavy debris and also for servicing a filter that filters the air on the intake side of the vacuum blower.
