With a super sucker like the
vortex the vac ports get so locked down that the water can't get in... ends up going all over the place..
minimounts and portys may not have the issue.
Ahhh.......
This issue has come up with my dual motor portable when running both vacuum motors. I found there were a few things I could do to mitigate this a bit.
1. Turn flow down so there isn't quite the torrent of water trying to gash into the tool. To date it seems better to have slightly less flow and more vacuum on upholstery. Well on microfibre and car interiors anyway.
2. Just use the tool in the reverse direction.
3. Dry lift chemical treatments and pre-spray moisture from the fabric with a dry pass before a wet pass. You get a second hit from nice strong chems so you need less water to rinse. And you make the fabric drier so the lockdown once you turn the water on is less severe.
Actually Mike and co-contributors, I always dry pass before rinse pass on any upholstery or carpet. It makes the job easier to risne and dry and I get better chenical enconomy.
But.... In being completely honest with you, it's obviously more useful for small operators like me with more concern about chemical waste and less capactiy for recoery. So like you say, portables.
Love my portable guys. Took me a bit to get one, but it makes life simpler for sure.
Toys like old DriMasters are new to me..... It's a bit of fun.
Thanks.
