I know a lot of you guys use different psi at the wand i have tried lower psi around 200 but when i do this i find i have to move the wand slower to get the desired result if i turn it up to around 400 i can move the wand much quicker and get the job done quicker too i still make about 3/4 dry strokes i was wondering what the benefits are of lower psi i mean if you are making slower passes then you are probably putting as much water into the carpet as you would with a quick pass at 400 so the theory that you leave the carpet dryer with lower psi is for me a fallacy.
The only time i use less psi is if i am using my Magma heater then i find the extra heat compensates for slightly less psi, all in all i can do a room far quicker using a high psi and i was wondering why use less i know you can get good results using less but it makes the job slower so why bother.

If I use the wand at anything below about 300
it's virtually useless.
The jets in mine are 110 015, would changing to
110 010 solve this problem i.e. less volume but
more pressure?

i think it all depends on your prep work, i run just under 300 and feel this is adequate for rinsing. because all my cleaning is done prior to the wand hitting the carpet i don't need high pressure to aid cleaning, and therefore am just rinsing out the prespray. it also depends on soiling levels which determine how much prespray is used. more prespray requires more psi to rinse, a lightly soiled carpet uses far less prespray so i can quite easily drop to 200 unless of course its been hit by the custmer with those mickey mouse toys, in which case a high psi is needed again.

I average 250 / 300 which seems more than enough and don't exactly hang about. It's probably what suits you best and like a lot of things depends on your technique/solutions and preferences

I make my wand passes at the same speed on virtually every job. Average pressure at 300psi, up to 400 for real grot jobs on cut pile, and down to as little as 200psi on tuffed low profiles.
Reason I drop the psi for tuffed low profiles, is because if you hit them with 400 psi, no matter how swiftly you move the wand, the psi will blast it through the carpet wetting the backing and at least the top of the underlay.

I always agitate using my Host prior to extraction so i dont think it is that. most of the dirt is separated from the fibre with this process anyway but i still find a higher psi works better i did a poly with a very thick pile it seemed to take forever at 200psi so i turned it up and this worked better the carpet was almost dry when i left.

With a portable I do all the "cleaning" prior to wanding at 300.
With the TM I use 400 but "clean" less in the agitation phase.
Waste of money and resources to do the majority of the work in the agitation phase, may as well use the porty all the time
