It is amazing how much dirt/ pet hairs was missed before using the Evolve Pet Elite Cordless Vacuum. It is the first cordless vacuum I have owned and I am very pleased with it. I think it does as good or better than my heavy whole house vacuum and is so much more convenient. My house is two stories, so I wish I had a second one! Also two batteries would have been a good move because I can get through about half by lower floor and the battery needs to be recharged. I also agree with other reviewers that said the placement of the on/off switch is problematic because it frequently gets turned off inadvertently.
