Wow! I never knew how much these things actually help! I always was suspicious but thanks to influenster I was able to try it out. It is on the quieter side don't you don't hear it much. It actually picks up most of the dirt on the floors. It can't get to the corners or up against the wall, which would be obvious because it's round. It doesn't pick up kids toys lol. My son left a Lego on the floor and it beeped loudly and stopped waiting for someone to pick up the toy.. so that's a plus! Overall 5 out of 5.
