It does not denote the operational horsepower output of a wet/dry vacuum, but rather the horsepower output of a motor, including the motor's inertial contribution, achieved in laboratory testing. In actual use, motors do not operate at the peak horsepower shown. ***CFM, Water Lift, and Air Watts tested to ASTM standard at the end of included hose.
