Hello Brad Buchanan.
Your vacuum rated at (PEAK) 6.5 horses
should draw 4849 Watts at 120V?... NO WAY!!!
It probably meens that while starting will draw that much. Staring a motor will take 3 to 6 times its rated running amps, even if it is for a split second. May be that is were the unrealistic number comes from! Get an amprobe reading and you'll know the REAL numbers. How can they state that much H.P? I agree with you!
