Will 4 HP cut it for most basic household and garage clean ups?

For the record, 4 horsepower is 2980 watts. So either you aren't running this off a 15 amp wall outlet or they are lying. The deffinition of one horsepower is 745 watts of work.

You raise a great point. The specifications list a 1,200-watt motor drawing 10 amps at 120 volts, which is only about 1.6 horsepower of electrical input. Actual continuous mechanical output would be lower due to inefficiency -- maybe about 1.2 HP continuous.

However, peak HP is generally how shop vacs are marketed. Amazon happens to have an incomplete listing. The Home Depot listing makes it clear that the 4 HP is peak: https://www.homedepot.com/p/Stanl...cale=en-US

good inf! listing it as peak is still crazy when the peak occurs only in lab conditions.
From shop vac:
"Peak Horsepower" (PHP) is a term used in the wet-dry vacuum industry for consumer comparison purposes. It does not denote the operational horsepower 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, Shop-Vac motors do not operate at the peak horsepower shown.

The HP rating is likely measured when the motor first starts, there is usually a high draw on startup. So they use that number to ficticiously say a rating at that instead of what a standard 10 amp cord will handle. They do the same exact deceptive nonsense with speaker ratings to deceive people into thinking they are getting more than what they are paying for.
