Hi Cameron,
I'm probably some what prejudiced but I like features that other machine have instead of the one your asking about.
1) 2" inlet and ball float. I think this is very important for air flow and carpet drying.
2) I like bigger wheels and casters, and I like them to have ball bearings
3) I like the 3 stage vacs that Mytee uses for the performance.
4) I like the Pumptec pump with the AC motor and the high flow cam for best results and longer life.
I could name other things but I realize it is some what subjective. This is just my opinion. And we know those are like noses, everyone has at lest one.
John
