Sears Horsepower BS

The Radio Shack stores (last time I was in a Radio Shack store around

Sears store to buy my new Craftsman wet/dry vacuum cleaner [[i's still

Horsepower

I thought the Ethics in advertising people made these people STOP using
fraudulent horsepower claims. Sears Horsepower is a JOKE.

To arrive at their insane figures, they do the following:

a) feed the motor with wires the size of your wrist and a HUGE breaker.

b) lock the rotor to prevent it turning.

c) read the current at it's maximum just before the armature melts down.

They then multiply the nominal, before any load, line voltage times the
locked rotor current to get horsepower figure that you will NEVER see.
It's all BS.

Vacuums are weird things anyway, the more clogged up the hose gets the
less air it allows through. The motor actually works LESS with a clogged
or restricted hose than it does when pumping free flowing (read
'non-vacuuming) air. The thing may get warmer because of a lack of
cooling airflow, not because of greater work being done.

I get roughly THIRTY amps current draw needed to provide a five horse
rating at 120 volts. That would mean, what? Ninety amps starting current?

I wonder why there hasn't been a class action suit over this.
