I've never used a 17" rotary apart from Nu-Life hard floor course, my Victor Sprite was 15" and seemed plenty big enough to be fair for both the small commercial's i was doing and hard floors. I stopped using rotary's for doing domestic as found it a pain if furnished and also taking up stairs, so generally use floormac or sebo for domestic.
What i am considering is getting Rocky for hard floors and maybe when the occasion allows on larger commercial carpet and a cheaper and lighter rotary for general LM cleaning for both domestic and commercial.
CleanerCarpets sorry for not getting back to you sooner, i might have to wait a few days before making any decision as my pump head needs replacing on my HWE machine and that will take a big chunk out of what i was ear marking for a rotary.
Hector, you still didn't answer my question or maybe i didnt' phrase it right
what make and model do you use?
Adrian, I don't do much commercial carpet cleaning, just odds and sods now and again but thinking of doing more of this work. I'm not that confident on rotaries, maybe i need to find the right one with the right balance, not yet decided one way or the other on 15" or 17" but when i did have my 15" i used 17" pads and i'm assuming a 15" is easier for a novice rotary user to master.
