First of all, I ought to set the context. I've been working overseas for a few years and I'm wanting to come back to UK into semi-retirement. I want to do a bit of carpet cleaning that will keep me out of trouble and not be too physically demanding. LM is certainly the way to go for me.
I've done a few encap jobs on synthetic short-pile carpets with a rotowash. It worked fine as I spent sufficient time on the prep.
(i) thorough vacuuming
(ii) prespray and agitate with rotowash
(iii) rinse with clean water with rotowash.
Yes, it was a little time consuming, but that's not the major issue for me in my particular context. I'm not looking to rush from job to job maximising my productivity and income.
The customers I would be looking at are churches (many of which are carpeted), primary schools, smaller shops/offices etc and maybe a few domestics with suitable carpets and no stairs to clean. I know it's a limited customer base, but it's enough for me for now.
Anyway ... these are the machines I've been looking at.

The attraction of these machines is that they are simple, self-contained and reasonably substantial. I imagine that with good preparation, they should do a pretty good job.
(They also have the ability to clean hard floors.)
What do you, the much-more-expert-than-me guys think, given my context and target customers?
