I just bought a replacement Big Green for the one that we've had for about 10 years. The main motor bearings just went out in my current one, but it owes me nothing. That thing was a beast. It cleaned my carpets, and my friends carpets, hundreds of times, and it did a great job every time. Actually, when the motor bearings went out in my old one we were at a friends house they were moving out of, helping them clean the carpets. When I say we put that Big Green through a wringer I mean it. It earned our respect, as evidenced by us purchasing the replacement Big Green. I didn't mention it, but have four cats and large dog. So we may clean the carpets a bit more often than a normal family.
