Shark Rotator Powered Lift-Away XL Capacity, model NV755. It can convert from a push vacuum to a hand-held vacuum.
Repairs and troubleshooting found here may also be applicable to models NV652 and NV752.
My vacuum starts running as soon as I plug it in. I push the on/off button, but nothing happens. I cannot turn it off unless I unplug it. How do I fix that problem?
