Airflow vs Suction for Carpet Extractors

[ridgidwd0670]

Which is more important between airflow vs suction for carpet extractor machines when it comes to removing water from carpet?

I've been using a Ridgid WD0970 (aka Workshop WS0915VA) 9 gallon vac & it pulls 74" water lift (I did the measurement with some dirt in the bag; may pull more with clean or new filter) with the Shop Vac Steam Team kit & the living room carpet (1970s-era wall-wall shag) was dry within a hr

I haven't tried the Steam Team with a larger Ridgid WD1280; but the Steam Team nozzle won't pull off the floor so easily with the Ridgid WD1280

The Ridgid WD1280 pulls 54" water lift

Yrs ago I had a Hoover SpinScrub (late 1990s-era classic ; pre-TTI) & I thought it had low airflow/suction but I didn't have a way to measure the Spinscrub's water lift (I no longer have the SpinScrub Steam Vac)

Does the nozzle have to 'stick' onto the surface for maximum water extraction?

I've generally heard suction aka waterlift is better when picking up water

I don't know

but aside from suction/waterlift/airflow, I feel like weight is also important. I remember back in the late 80s/90s, we had a bissel big green cleaner (like a large version of a portable deep cleaner. The difference when you're using this vs an upright (at least to me) is that you can sort of push the head of the cleaner into the carpet to extract more water. With uprights, you can't do that and if you have super low pile carpet like me, the upright cleaners only work for me if I TAPE a hand weight to the top of it so it meets the carpet more. I tested this and it extracts so much more water but it's such a pain. I wish Henry Wash was available in the US.

This might be a suitable alternative to the Henry.

I think George is available here, I'm not sure if it's similar to the Henry wash but it does have the ability to wash carpets and hard floors.
