So I recently came into possession of one of these beasts. When I got the poor thing home I discovered that it had been used without a bag! The entire machine was absolutely full of filth! After a complete disassembly and a good cleaning, I turned on the machine and was pleasantly surprised with the end result. I know some people have questioned the styling of the challenger series, especially the floral green disaster, but otherwise I really think it's a solid and well designed vacuum. One question for those of you that also have a Challenger...what type of bags do you use in it? I'm currently using an Electrolux tank bag with a premotor filter I put in the back of the bag chamber for good measure. So far it seems to be working alright.
