After listening to Alan Simmons Jnr at Carpet Cleaners Carnival I thought I would crib of his Web Site, after all a guy with five vans has got to be doing something right.

I then Clicked through to Chem Drys corporate advert and they claim with agitation and their carbon water you need no more than 120psi   so it makes you think regarding investing in bigger pumps etc

Perhaps better to put money into better agitation equipment if you do not already have it.

I think the lower the psi the more prep that is needed, I remember twenty odd years ago when I used a stimvak single vac and 50psi maestro machine coupled with there power brush I got good results but a lot slower pace than I work at today

Who is Alan Simmons?

[stuart_clark]

Owns a chem dry franchise in yorkshire I think

[John Kelly]

Personally I think Chem Dry made a rod for their own back. They started as a low moisture system using bonnets but then moved over to HWE. Trouble is all their marketing had been directed at dishing HWE showing videos of wands spraying massive volumes of water etc. They also sold on carpets dry in an hour, so they have had to limit to a very low volume system with carbonation. Even their truckmounts are 150psi.

Because they use carbonation , the pump is just spraying down product , not trying to get into and between the fibres.

I definately clean far better now I have stopped using CD products .  The only better product CD have is leather cleaner.


What they are is a carpet cleaning marketing company , and they do that very well.

It depends on what you are cleaning and what product type you are using.

Microsplitters on a domestic carpet 100 is fine.

Pub carpet where, the tables stick to the floor, using detergent in the tank, then quite a bit of heat and blast it with what ever you have.
If the pump is rated at 500+ psi and you run at 200 ( the most I ever ran at with my high performance pump)  the the pump will keep that pressure and not be overstrssed. If it is a 300 pump and you attempt to run at 300, setting that pressure with tool valve shut, you will find most pumps will drop to a lower level as the pump cannot maintain the 300 while spraying.
It also depends on what you can suck up.

Technique is part of the clean my local cd (not Allan although his franchise works in my  area) mainly still use low moisture they had trouble getting carpets dry with hwe cd Porti.

I'm guessing that if you keep to the cd system that most carpets can be dry quickly but there is a huge amount of variation is carpet type and soiling.

Cd did shoot themselves in the foot but do customers remember that? They are getting a better clean.

A few months ago I had a problem with the psi on my tm and it was running at approx 150-170 psi and it was so slow and believe it or not wetter!

well I was given advice by few guys that 150psi supported by agitation if enough for domestic cc
they seemed be experienced in business so I truly believe it

[Susan Dean (1stclean)]

chem dry ? oh yes I remember them they lost most of there insurance work because they were crap and now you hardly see them funny isn't it all the hype and there nearly gone guess us little boys are doing sometime right

[Ian Gourlay]

Susan

Its time you gave a marketing Masterclass

Yes, it's fine, as long as you run short hoses, are prepared to re-fill the tank often, and move the machine from room to room (well, almost) and carry it up stairs.

More power (i.e. bigger machine) allows for longer hose runs, more capacity (rinse and waste tank), and will have much better vacuum (drier carpets).

I ran a 150psi for 2 years, successfully (and I've still got it for back-up), but I wouldn't swap it for my new Airflex Storm.

[COLIN BRIGHT]

i thought that every thing got cleaned at 1200 psi, 

[Shaun_Ashmore]

Colin you thought you had to charge everyone £1200.

[Mike Halliday]

I did a spell of connecting directly to the outside tap and feeding it through a propane heater, tap pressure is 40-55psi but flow is 15lt/min.

100psi can 'clean' carpets but if you are using 01 jets how much dirt are you actually removing, definitely not the deep down dirt. Pressure causes deeper penetration into the carpet

[stuart_clark]

I went on a Chemdry business seminar quite a few years ago (20) actually they demonstrated there carpet cleaning system, at that time they used what looked like a pump up gloria sprayer with a c02 charging system on the side, they said it was the bubbles in the carbonation that forced the dirt to the surface when appled to the carpet, then they used a bonnet machine to extract it !
They also used the theory of the straw in a tumbler of lemonade that the bubbles (carbonation) that lifts the straw, also lifts the soil from the carpet. But that was then, 1995 and I am sure CD have come on a fair bit since then! As we all have, they dont have a very good reputation where I live in the cleveland area as my clients have generally used them at some point before using me, I know Jason had a CD franchise not far from where I lived but think he was in the restoration business so thing that
CD do very well from


Stuart

[Shaun_Ashmore]

I agree with mike if you have the flow and the correct jets then 150psi is achievable for a good clean it's an either or depends on what you come across.

What they are is a carpet cleaning marketing company , and they do that very well.

Surely that applies to every carpet cleaning business.
