Wow! This Roomba is amazing! It vacuums so well! The battery life is excellent and charges very easily. The noise level is very quiet except when it empties the trash. Once you first get it you're able to map out your house for easy navigation for the Roomba. My only complaint is getting it to connect to WiFi, it's not the easiest thing to do. Overall I love this piece of equipment, I would highly recommend getting one if you're in the market for a Roomba!
