    I just started a Carpet and Tile Cleaning Company and I'm getting ready to buy all my equipment, but I cant decide if I should just buy a Mytee M12 and save the extra money instead of buying 2 separate machines, but bottom line is the M12 only offers 250 psi for carpets, is that enough? or should i buy the mytee 1003dx that offers 450psi?

    What is the ideal PSI for cleaning carpets?

    Most residential carpets (in my opinion) I go about 350-375psi.
    Severely trashed, flood damaged, urine etc I go around 400psi
    Commercial carpet with no underpad and trashed (motels etc) 400-500psi

    250psi is ok for wool, upholstery or gentle fabrics, but you wont get any of the
    heavy duty cleaning out of it.

    Again, just my opinion!

    I think the Mytee m12 will go higher (up to 1200 psi) only NOT with heat.

    2 reasons
    1) Electric heat wont keep up w/the flow
    2) with the pump turned that high along with heat, it will draw more amps and trip breakers.

    Thermax was bragging to me about their 60PSI machine, and how some SS machine broke down, and they rented a 60PSI machine from them...60psi? thats just above Rug Doctor status..

    Higher pressure = Easier cleaning

    I am not familiar with the two machines you mentioned, but I can offer my 2 cents. You will be glad you have that extra pressure when you run into severely trashed carpets. It will make the job easier since you are having to pull more soil out of the carpet. Even if you prevac a severely trashed carpet a lot will be left behind that won't come out w/o a good TLC and heavy rinsing with the machine. More pressure = faster and more efficient rinsing. Less pressure = more wand strokes and harder work for you. Of course, Like Richard said, you will adjust the pressure to meet the demands of the job. I sometimes turn my truck mount down to 250 psi for carpet and often, most of the time in fact, work at only 300 psi. I have found that my machine does a great job at that pressure and I get scalding hot water at the wand. I would go with the higher pressure machine even if it cost a few hundred extra bucks. I think you will be glad you did.

    I have been creeping closer and closer to 600. I do not do any residential just commercial and apartments. The nasties really come out nice with high psi.

    I have a portable with 100 psi pump which is ok but since using a TM i hate using the portable when I have to.

    Just made the switch from porty to TM myself.

    100 psi to ungodly pressure.

    I will be wearing a helmet, glove, eye protection and my batman undies.

    I think you should look At m-5 by mytee . 2 3stage vacs 230 cfm 148 lift 500-600 psi enough for grout 2 inch all the way , Spend the extra 500 for a booster for long hose runs , Buy a used propane heater or electric

    300-350 for residential with pad, 400-450 for commercial.

    psi for carpet cleaning

    I run my tm at 500psi but im alway 150+ ft of hoses i park at people mail boxes not in there drive way and i do apt sometimes im almost in the parking lot

    my mytee 450psi off of 50ft hose i leave it at the door

    I would get the best machine you can so as you grow you dont have to worry about upgrading

    you still have to adjust your psi depending what you cleaning upholstery etc.

    I currently clean residential carpet at 400-600 psi depending on amount of soil. When I first started cleaning though I started with a My Tee which had very low pressure. To make up for the lack of pressure I would agitate the carpet with a 175 machine and then clean using my My Tee and always had good results.

    Match your PSI with your vacuum.
    No point in dumping tons of water at 500 psi if you can not recover it.

    One machine you never want is 450-500 psi with dual 2 stage vacs. They are very popular in Canada and are really a rug soaker not a rug sucker.

    What ever you get make sure you have dual 3 stage vacs.

    happy cleaning

    Ken is right "Match your PSI with your vacuum."

    1. the m12 comes with 2 pressure pumps. a 250 psi pump that uses heat and a upto 1200 psi that cant use the built in heater do to amp restraints. you can use the 1200 psi pump @450-600 psi to clean carpet with but will need to use a external heater.

    2 i generally clean carpet regardless of type at 600 psi. I have the vac to support this, a portable may not.

    3. you can clean very well @ even 35 psi. you just have to use a technic that is compatible with the equipment used. at lower pressures you need to increase
    1. flow. use bigger jets
    2. agitation, pre scrub all traffic areas.
    3 a higher quality free rinsing pre-spray

    the purpose of the portable is to rinse away suspended soils. you dont need high pressure to do this if you suspend the soils with a quality pre-spray and proper agitation.

    The vacuum part of the equation is much more important the the rinsing portion. you want to be sure to remove as much of the suspended soils and moisture as possible. So as Ken said "Match your PSI with your vacuum."

    Bigger more powerful units including truck mounts dont clean better, they just make the job easier and faster for the tech. A good cleaner will get a good job done regardless of the power of the equipment. It all comes down to using a technic that best utilities the equipment available to you

    It's not that simple...

    Most truck mounts use 1/4" pressure hose. And that hose diameter loses a significant amount of pressure along the way, due to the resistance that it produces. Over a 200 ft. section, you will lose 200 PSI, typically. And that drop is more if you lose liver reels.

    Next, you have to take into account jet size. The size of the jet is what actually determines the pressure of the delivery at a given flow from the system. For instance, a #4 jet or equivalent wand will produce more pressure than one with a #6 equivalent, if you change between them on the same system with the same setting at the machine.

    So, a guy who cleans with 150 feet of hose with a specific jet size, at 500 PSI, may actually have less pressure than another guy with 300 PSI and a smaller jet size. But he will not have more flow. And flow is actually more important.

    Many portables use 3/8" hose, which offers substantially less restriction in the first place. And they all are closer to the wand than a truck mount typically is. As a result, the pressure at the wand is almost the same as at the machine for a typical portable.

    So, it's difficult for two cleaners to be speaking "apples and apples" when comparing pressure, or flow, for that matter. Much less so, if one is much closer to the job than the other is...
