Love my Shark Ion. I’ve had mine for almost 2 years. She cleans the hair and dirt from my home with ease. 7 cats and a dog produce a lot of hair. Although I don’t schedule her to run at certain times I do press her button before I go out and return to a vacuumed house. I never thought a robot vacuum could clean so well. I could never live without “Berta” if she should ever cease working another one will replace
