There's been talk about warranties being voided by rotaries for years. Nothing new there at all. But if we really are concerned about this, we'll all need to get rid of our rotaries, OP machines,
RX20, HOSS, Rotovac, and possibly even our Cimex (even though by the strictest definition it's not a rotary). But that may be over reacting; let me explain...
First, let's consider what triggers the mills concerns. One thing... Warranty claims. And what fills up the column for warranty claims with rotaries? My guess is that it's primarily coming from janitors, NOT professional cleaners. Some knucklehead janitor is out there with a rotary and no knowledge of carpet and he does some damage. Blip - that shows up on the mill's spreadsheet. But is that realistic? We can't say there was any level of professionalism that caused the damage. The truth is that a "professional" cleaner can use any of the tools in the list above and NEVER damage anything - we all know that.
Next, lets think about the actual warranty itself. Let's face it, we all know that the mill is probably not going to end up paying on most claims anyway. They build a good product. So they're not likely going to be paying for a failure resulting from a professional cleaner. And if by some slim chance a cleaner actually does cause damage a carpet - then he did something wrong and he should be held accountable. But that's what insurance is for isn't it?
Now to get to your question directly. The Cimex is NOT a rotary machine. It is a planetary scrubber. It doesn't spin around in a circle like a rotary machine does. As the drive deck turns clockwise, the drivers turn counter-clockwise. So as it would be damaging the carpet it's actually un-damaging it at the same time. You can park it on the carpet and let it run and there won't be a problem.
Back when we first started hearing the concerns over rotaries coming out of Dalton we took a proactive position and sent a Cimex, along with
Releasit, and
FiberPlus pads to Professional Testing Laboratory in Dalton. PTL is the third party testing laboratory that's used by the CRI and the mills in Dalton. PTL ran the Cimex on commercial carpet making 22 passes. Guess what - it passed.
Take a look at the test results from Professional Testing Laboratory.

So the issue of a Cimex possibly damaging a carpet should not be even a remote concern.
