I had a roomba before and although the idea of a roomba sounded great, I just didn't love the model I had! It was so loud and the cleaning tray was very small. It needed multiple times emptying! This roomba is super quiet! Which is a major plus for me! The emptying bin is also a huge plus! It can empty itself as often as it needs to on its own! I was nervous to try the mop feature, but it worked well on my hard wood floors! I don't have a large house, just a small 2 bedroom apartment it it gets the job done! One less thing for me to do so often!
