I like the cordless part of this vacuum! It is super easy to maneuver around areas. The width of the vacuum fits under my chairs which is super convenient. The battery pack lasts for what I use to clean my carpeting. I do clean out the dirt cup more often than not as I have 2 bassets and they shed like crazy. This vacuum does a great job of sucking up all that dog hair! It's so lightweight that when carrying on the stairs it feels like nothing. I am so happy I bought this vacuum and highly recommend if you have dogs!
