That’s right. There are actually lightweight vacuums that are battery operated. These lighter uprights are designed to be used for quick cleanups of small messes. In this case, cords are a nuisance as you have to unwind them and find an outlet. If you have a small pile of crumbs to pick up it’s almost not worth the hassle. It’s for this reason that the less powerful, smaller vacuum cleaners are recharged between uses. When you are finished using them simply hang them back on the charger, which can be conveniently tucked away in a closet or the garage. The next time your dog tracks some dirt in from outside you can grab the vacuum and go. It will take you less time to clean up the mess than it would have just to get your full sized vacuum out and plugged in. The vacuum cleaner is constantly evolving to meet the needs of today’s busy households. The lightweight vacuum is a testament to how the companies are listening to the consumers.
