The performance of this product is merely average. I was expecting for it to do a little better, but was quickly left disappointed. The battery lasts about 20 minutes, which is good enough for most tasks and should be enough to clean your car with. It definitely isn't powerful enough and you will have to go over the same area repeatedly. The main tool connects perfectly, but the other 2 don't click into place and feel like you're trying to use something on your cordless vacuum cleaner that isn't really meant for it. The main tool also gets hairs tangled into it easily and tightly. Really best used for carpet only, but I don't feel it gives a deep clean, though. Not worth the price, unless you absolutely need it to be cordless and don't want to buy anything more expensive.
