Thought you might like to read some comments from Gordon Hanks. He played a major role in bringing this new tool to the industry.
I read a post yesterday concerning the CX-15 and since it is affectionately my creation (with the help of some very talented engineers that work at Hydro-Force and include the original inventors of the hard surface rotatory sprayers like the Turbo, and the SX-15 as well as the Zinger) I thought I might be able to answer some of the questions.
Obviously I am biased but in this case I will try to be completely honest.

The video at the beginning of the post was shot on real carpet jobs with real soil. The brownish beige carpet was one of the jobs I helped with. It was shot at Roma's Italian restaurant in Salt Lake City Utah. The truckmount was a
Prochem Everest set at 900 PSI. Normal commercial setting for the CX-15 is set at 600 to 800 PSI. The technician thought this was extra dirty so he thought he would give it an extra kick. When we had previously cleaned this same restaurant with an earlier prototype, we ran at 800 PSI and it performed equally as well. The CX-15 had the commercial bar on it which has two 1502 jets. The commercial bar has a 30 degree angle to the carpet. Note that the bar on the hard surface SX-15 runs with a 22 degree angle. In addition there is an outward kick angle of 7.5% moving the spray closer to the edge.
There is no kick angle on the residential bar which is somewhat shorter, set at a 40 degree angle to the carpet and fitted with 11002 jets. These create an almost baby soft spray that reaches close to the edge and is very gentle (yet amazingly effective) for residential carpet. The residential bar is designed to run at 400 – 600 PSI.
The CX-15 concept spent years in development. We worked for a year trying many different configurations of jets and angles to get the best combinations for commercial and residential. However, there is nothing wrong with trying other jet types or configurations for the tinkerers in the group as long as you do not do damage to the carpet. The current configurations of the spinning bars are designed to maximize the rpms of the bar while keeping within the swivel’s maximum RPM.
Back to Roma's restaurant. It is cleaned every six months. In fact six months prior to the release of the CX-15 tool we used our prototype on this very restaurant with the same amazing results. In my opinion they let it get too dirty between cleanings but I just work here. In the past, this carpet has been regularly cleaned by two technicians using a glided Prochem titanium wand running at 500 PSI and very hot temperatures. This restaurant took 3.5 hours on all previous cleanings. With me as the second technician (basically the hose handler) – you will see my good looking legs in the video – we did the complete job in just under two hours with the CX-15. This including moving a bunch of tables. Yes, the technician did have to go through a learning curve with the CX-15 before he could move that fast, but the CX-15 saved a lot of time on the job.
Why so much faster? Once over is all that was needed. Going over the carpet a second time gave no visible improvement. No vacuum stroke was needed. This carpet had the type of low pile where we could have pushed the tool forward with the vacuum
glide on the carpet to effect a vacuum stroke but the carpet was nearly dry after the first cleaning stroke so that was not necessary. In fact the first half of the restaurant we cleaned first was bone dry when we left. This was because the truckmount had great suction, and the tool maximizes air flow and water extraction via the glide and head design. It also contains all the steam within the head so the air is not saturated with moisture which slows drying.
We presprayed with the label suggested dilution of Bridgepoint Flex Powder with Citrus Solv. On their previous cleanings they presprayed with the Flex then ran over it with the Brush Pro
CRB machine to get extra agitation before wanding it. The Brush Pro was not necessary when using the CX-15. Since the agitation came from the CX-15 and not an extra step, that also saved a lot of time.
At my age and fitness level I can run a wand for about 30 minutes before I have to go to bed and rest. I ran the CX-15 on about half of this restaurant and went home with no aches or pains. It is almost effortless.
PS: We didn’t find it necessary to do any edging. That is not to say that on some jobs it may be necessary but we found that tilting the tool up slightly into the corners and at the wall that we got enough moisture to clean the light soil that was there. The CX-15 vacuums right up to the front and side edges.
