We have been very pleased with this little hand vac. It seems to run longer before using it's battery power than our previous one. I was easily able to do two sets of stairs (works well both on carpet and hardwood) as well as all around the edges of several rooms and still had power to spare, Haven't had it long enough to see if it continues to have such a long charge, but it seems hopeful. I also love the way it empties and that the filter can be washed out instead of being replaced each time it gets dirty. Just what I needed for those quick pick up jobs.
