Abstract

A wet/dry utility vacuum cleaner with detachable blower is disclosed. The detachable blower, when mounted in sealed relationship to a lid positioned above a utility vacuum cleaner drum, operates as a wet/dry utility vacuum cleaner. When separated from the utility vacuum cleaner drum, the detachable blower can be used for non-vacuuming applications. The utility vacuum drum lid includes two resilient and deformable latches: a releasable blower latch and a releasable lid latch. The releasable blower latch detachably mounts the detachable blower to the lid while the releasable lid latch detachably mounts the lid relative to the utility vacuum cleaner drum. The releasable blower latch has at least one reinforcing fin for engaging a complementary slot in the lid. The releasable lid latch has at least one slot for receiving a complementary reinforcing fin on the lid. The seating of the reinforcing fins in the respective slots, when the respective latches are in an engaged position, prevents the deformation of the respective latches and unwanted disattachment from the vacuum cleaner.
