I really liked this vacuum until it broke, not long after the warranty expired. Go read other reviews. It will break right after and they will just tell you that you need a new one. I dont expect it to last forever but maybe just longer that 15 months. I have other shark products that I like but I will be choosing a different brand for my next robot without a doubt. Also dont try customer service. He tried one troubleshooting technique and then just said "o, well you need another one."
