I wanted this vacuum so badly, and was so disappointed when I finally got it because of the static elasticity shocks when using on carpeting. The metal grounding plate is way too small, and it turns out that my hand was coming ever so slightly off of it when I was vacuuming, so I was getting shocked all the time. It was awful and I almost returned it.
BUT, then I switched the way I hold the handle, my wrist placement, so the flat part of my middle finger was on constant contact with the grounding plate (not the side of my finger like before, which caused disconnection issues), & the problem is completely solved.l! Love this vacuum.
