Input:
I bought this vacuum about two years ago (the version with only one battery), and now need to replace the battery. Since this package is about the same price as two batteries, I figured I might as well just get it and replace the vacuum altogether. It's nice, I kept the old charger so I can charge both batteries at once.

The vacuum is great for a condo or a small house, a full charge can get you around 1000 sq. ft.  of cleaning done from my experience. It is easy to use and works very well. Make sure to empty the container once you see it getting full, I emptied about every 3 uses. The other version with the clear orange container is nice because you can see how full it was without taking it off. Come to think of it, I'll be keeping the dirt catcher from the old one too. Hair and fibers will tend to wrap themselves around the spinning brushes, but the simple design makes it easy to just slice them off with scissors or a box cutter if it gets too bad.

The battery in my previous one lasted almost 2 years before it got to the point where a full charge would only get one room at best. Having two batteries to alternate now should make them last longer, I'm hoping to get three years of use out of this package.
