OP versus CRB

The IICRC takes no position on which method is better.

'IICRC S100 lists the standard steps included in each of 5 industry-accepted cleaning methods, based on the Principles of Cleaning. The 5 methods include: absorbent compound, absorbent pad, dry foam, shampoo, and “steam” cleaning. There is no attempt to compare methods or declare a “best method.” Rather the focus is on specifying standard steps that must be included in the proper use of each.'

OP, CRB and standard bonnet machines including floor machines using bonnets (my favorite) are as we all know just versions of the absorbent pad method.  Looks like you are sold on the CRB machines for what looks like good reasons.

Have you noticed 3 out of the 5 methods are basic VLM methods while the other two use lots of water, the one being the biggest self proclaimed winners of the water wars.

So how long have you had the CRB unit?  Who is the manufacturer?  What is the worse carpet you were able to make like new with it?  Any pics?  We love to share shots.  What chemicals do you use?  How do your customers feel about being able to use their carpet so soon?

Actually the IICRC's stance on the cleaning systems now, is that they recommend whatever the manufacturer of the carpet recommends. And the manufacturers do not currently recommend any system that uses a rotatory floor machine. They believe it causes to much pile distortion. Most of the manufacturers only recommend HWE. Only a couple recommend the drum brush style system for the commercial glue down only. Not the rotary systems. So basically the IICRC's stance is, use whatever you want, but you may be voiding a few warranties here and there. I'm not against using a rotary, I love mine for commercial, but its what the latest stance from IICRC is. By the way any rotary including RX20 or RV360 are included in the void the warranty category. 

I agree. I carry equipment to do bonnet, shampoo and hwe. I'm just mentioning that is the current standard.
