I Love this sweeper. I love the fact that you can charge the sweeper and the extra battery at the same time. It does a great job sweeping. I swept our whole first floor and it didn't even sound like the battery was starting to die. I definitely would always use it with the brush on. It sweeps alot better. Good power and suction. I've only used it a couple times so I'm hoping the batteries have a good life in them.
