orbot vs challenger

[Perry]

It works real well for me on smaller jobs.It is a real work horse,on some berber(in basements) it is a little harder to operate but on cut pile carpet it works great. I decided to buy a defender and that works ok but need a wieght on it for commercial, but not on the challenger. Never tried a Orbot and like to get one but they are pricey in Canada.
But the cimex rules for those long hallways.
