4hp=2984watts (1hp=746watts). Your typical 15 Amp circuit breaker will only handle about 1800 watts. I'm sure they both will run on a 15A circuit without blowing the breaker so my point is you can ignore that instantaneous peak horse power rating; they are both going to be running well below the stated peak HP.
If they give a continuous current or power rating that would be more useful, for comparison, but I didn't see it for the Stanley.
Yeah. Whoever gets one of those would do us a favor if they posted the amperage of the motor, it should be listed on a sticker somewhere on the unit. HP ratings are always bogus, one way to obtain motor HP is 120v x amperage x 0.00134. The little husky previously SDed is actually a little over 1HP. This is still 2-4 times more powerful than your standard carpet vacuum, depending on model. Even so this method of measuring a vacuums effectiveness is still rough. A higher amp motor doesn't always result in more powerful suction, it really depends on the motor/canister/hose diameter and length..
The husky is rated at 175 ft³/min CFM while this Stanley claims a simple number of 75 CFM. They both have 1-1/4" hoses. Based on these numbers alone of airflow, I'd say the Husky has twice as much airflow. These numbers might be more marketing mumbo jumbo. Still I wouldn't be blindly turning in your Husky's for this guy If I were you.
