I live alone and was tired of constantly sweeping and vacuum my place. I purchased this vacuum and I love it. I set it to clean when I am away and it takes care of the rest. I let it clean freely throughout my house. one day it got caught in a wire and stopped in it¿s tracks. The unit was powered down were it was caught. I untangled the vacuum and it finished the job. All I need now is one that can mop.
