Review on Powr Flite BP4S Pro Lite Backpack Vacuum by Liz Taylor

I try to use the same vacuums for all models. If one fails, I'll buy a Power Flite. But this time the vacuum was different from the other 3. It has a different type of bag which I wanted to avoid and it comes with two heads, one high enough off the ground that it won't pick up grass in the classroom and the second closer to the ground, which is perfect, except the hole is small enough that it doesn't pick up small rocks or wood shavings. I can't use it where I bought it. It works great at the gym, but the cord is much shorter and I have to turn it on and off more often.
