Ken,
Agreed, pretty much all of the mills have frowned upon rotary machines.
However NONE of the mills have frowned on planetary machines.
You guys might be interested to learn that a Cimex was sent down to Shaw a few of months ago for them to evaluate. They liked it
We just got a call a couple of weeks from a company that manages a few large shopping malls. They wanted more information about the Cimex machines. The mall company is presently installing Shaw carpeting throughout their malls. And they've been working with Shaw to plan the best maintenance approach for their carpet.
Now can you guess what Shaw recommended that they use to scrub their carpets. Yep you're right, Shaw recommended that they use Cimex machines. Cool!
The Cimex has never formerly been worked through the mills. But that will likely change as we move along, as I'm pretty sure that Truvox and the current importer of Cimex in the US is interested in getting the rest of the mills to appreciate the machine's planetary design. Cimex has already won some major points with the largest mill, Shaw. So it stands to reason that the other mills will also like the planetary design as they get an opportunity to evaluate the machines in the future.
Let's compare machine designs for a momnet...
PLANETARY
A planetary designed machine can not possibly damage a carpet because of the way the machine turns. The drive-deck is turning clockwise as the brushes are spinning counter-clockwise. So it's actually scrubbing in two directions at the same time (right and left).
This means that you can park a planetary machine on the carpet and leave it there running for several minutes without ever moving the machine. And the carpet will not suffer from what we could rightly refer to as carpet abuse.
CYLINDRICAL BRUSH MACHINES
A cylindrical brush machine is also relatively safe for carpet fiber. No damage is likely to occur with this design, and that's why the mills have already recommended cylindrical designs for their carpets. Whittaker has already done a good job of pushing their machine through the mills. As a general rule, the mills take no exception to any kind of cylindrical brush scrubbing action.
ROTARY & OSCILLATING MACHINES
Rotary machines can damage a carpet. Rotary machines spin in one direction, counter-clockwise. And if Rotary machines or OP machines are run improperly, the carpet can be damaged. If the carpet isn't lubricated with sufficient liquid, the carpet can be burned. This is especially a danger with olefin since it has a lower heat threshold. And cut pile carpets can be distorted if the machine is left running too long in one place without enough lubrication of the fiber.
Here's the bottom line.
Any of the machine designs, if used properly, can be used safely. It is only the very small minority of inexperienced, untrained, or careless cleaners who have created problems for the rest of us. And unfortunately the mills are then forced to respond to these dummies. As warranty claims escalate they obviously have to recommend against methods that might potentially damage their goods. But in the real world, the mills know just as we know, that all of the methods can be successfully used with proper care.
