1. A vacuum comprising:
- a housing defining a debris chamber;
a vacuum source disposed in said housing;
a transformer having a first winding and a second winding inductively coupled to said first winding; and
a pair of water sensing probes disposed in said debris chamber and attached to said second winding, wherein current does not flow through said second winding when water is not sensed by said pair of water sensing probes, and wherein current flows through said second winding in response to water being sensed by said pair of water sensing probes, andwherein said vacuum source is disabled when current is flowing through said second winding.
