No syndrome. I actually was a zipper hater for quite a while.I think you have big toy syndrome. Bonzer works fine. I know y’all are emotionally attached but I am not. The truth is I have all of them and this is how I see it;
Bonzer
Lightweight-Easiest to use
Works great in resi & comm
Drys carpet fastest
Self adjusting head
Cleans in forward & reverse
Encapsulates heat best
Handle could be built better
Be nice if had a 14” or 15” available
Zipper
Heavy
Built best
Have to adjust head
Works best in comm setting
Standard jet cleans forward only
Loses heat our sides
Is available in larger sizes 15 & 17
Spinner great but only works on large Truckmounts or over wets and less waste water removal
Lifetime tool
Bonzer is a Toyota and Zipper is a Lexus. Two different markets. Both get you where your going.
Everyone has their preference, to me the bonzer was really not a good tool mostly due to the head size. I cant stand a 12in wand unless I'm doing a furniture heavy residential like a townhouse or something.
Big open areas (which these tools are designed for) is really painful with a 12in tool
The handle design also really got to me personally and imo the tool just doesn't have a commercial quality look to it.
I do know u have industry beef with others and I get it, you also have a thing with rotovac.. I don't mean this thread to spark any of that drama and nobody asked me to post anything.
