Does anyone know of any helpful material on the “SHARK ROTATOR NV750W SERIES”? I had a blockage in the bend of my handle and while attempting to free it i damaged my contacts. Anyways; because I did this damage myself I did not abuse the warranty and just ordered a replacement handle and hose for $84.00 CAD. They sent it fed ex right to my door which is nice because I live in a rural area. However, I connected the new one just as you would and to my disappointment; when I pressed the power button on...NO POWER, no power on any of the three settings and yes I have plugged it into a functioning wall outlet.
