I agree with all that was stated by other members above, I have a Tristar CXL which is very light, easy to get around with, excellent suction, and very durable. It is probably by far the strongest cannister I have seen or used, cleaning results better than any other cannister I have seen. The bag is easy to clean, and the attachments are super. I have never seen or used a 'new' model, so I am not sure if the new machines are as powerful or durable, but would like to hear from other members who have a new machine what they think of it!
