Hi Cleandry
I can recommend Texatherm to you.
I assume by your name that you will be looking at low moisture cleaning systems to offer your customers which of course is
the big benefit with Texatherm and DF.
I use the system on commercial and domestic and have no problems with it at all as you say the system is far superior to CheDry's method as is DF.
I would wait a while before buying one though as they are about to make one or two changes to the current system namely the water heater which at present has no way of draining out the excess water/solution hence you have to tip the water out when finished which can be awkward and with potential of damage to the unit. The new unit will have a built in drain valve along with other modifications.
I must be stronger than most as I do not find it heavy taking up stairs and unlike CMS I have found the cleaning capability beyond what I expected and coupled with fast drying,ease of use and low noise along with the fact that it is also cheaper than DF and most other HWE machines.This does make it a good buy IMO to add to your kit.
I must point out that I do also use CFR and on occasion use both systems at the same time should the need arise.
You can also use the rotary in conjunction with Charly Pads and MS so in effect you will have two different systems to offer you clients if you go down this road.
Check it out, look at DF as well along with CFR and the Eclipse and this will give you a good idea about just what it is you want the system to do for you.
