Heat is just as important......and vacuum is equally if not more important
When I got kero heat my
rx20 took a rest as I tied off the trigger on my
prochem wands and bumped my vacuum up with a larger engine for more vacuum and increased the water flow to 10....12 flow
Wands have certain advantages over rotaries especially in homes...no power cord.safer ... No bumping....or chewing up carpet wads....go under furniture..upstairs
Zipper will clean anything a
rx20 will if you have enough heat vacuum and water flow.....I clean filthy resturants with no rotary....
I only use a wand for stairs...or gum.....
I do agree we should try to go beyond wands because they will break down your body in time.
