Does anyone have side by side experience with the whittaker 20' and brush pro 18" machines. I own a Whittaker. I liked the idea of the larger on board solution tank and the integrated catch tray that does not extend off the machine. After a couple seasons of using it, I have noticed that the Brushes break in quickly and lose their bite on the carpet. I am also kind of disappointed with the lack of solution application and lack of spray width across the brushes. I like the machine itself, however it seems less durable, especially with constant transportation, than my 10" brush machine. Mind you, this machine is used in specific situations that are perfect for Crb work vs extraction or Op machine.
