What moves the disolved soil from the carpet is airflow, so coupled with good wand technique a high airflow portable will generally out-perform a similar one that is vacuum optimised.
If you are flood extracting the the more vacuum (water-lift) you have the better as you will be wanting to suck THROUGH the carpet whereas for normal cleaning the air movement should be more ACROSS the carpet with the cleaning solution, after hitting the carpet, moving as quickly as possible from impact point to the wands recovery slot.

That is one opinion and technique. There are special tools such as water claw that works well with portable or truck mounts to remove water from carpet and padding. I do believe that designs of wands and air flow can make a difference. I believe in taking your time, and doing an extra dry stroke will increase the speed of the drying time. I differ in that when cleaning a carpet I prefer to pre spray with solution and let set 10 minutes. I then extract slowly using a circle pattern and acid rinse or neutralizer through my solution line. I believe this allows the soil to break loose easier and allows the solution to do a big part of the work. I also believe that it cleans the carpet deeper than a quick spray and removal of solution. Everyone does it a little different. My method is works best for me and that is determined by my opinion formed from trying different methods and results.

Dan, We are not so different! My standard procedure for spray/extraction cleaning is: - Pre-vacuum thoroughly.
- Apply pre-conditioner (either an active colloid or microsplitter)
- Thoroughly brush in using a CRB machine on a piled carpet or rotary or OP on low-profile carpets.
- Microsplitters require no dwell time but other pre-conditioners are allowed at least 10 minutes dwell.
- Carry out extraction rinse, normally with plain, hot, warm or cold water.
If required for a specific reason, such as dye stabilisation, I may use an in-tank additive but since my pre-conditioning products are all detergent-free and free-rinsing, the extraction rinse is just that - all the required soil break-down is conducted within the carpet before the wand is applied to the carpet. This is also the reason why the temperature of the machine water has little influence on the cleaning process. Where we differ is that I would not clean in a "circular pattern" since most of the carpets that I clean are wool or wool-rich and they benefit greatly from proper pile treatment during the rinse process.
