This Roomba vacuum is amazing, I have several animals and am always dealing with pet hair and dirt they tracked in. This vacuum does a great job of helping me keep up with the mess. The dust bin is large enough for it to go over my whole house and pick up all the hair in one go. I used to have a different brand and it would be so loud that you could hear it from anywhere in the house. This one is very quiet and not jarring at all like the other one. It has great power and I never have a problem with it not being able to pick up anything.
