While I agree with most of the comments already made, I think there might just be a big onough niche market for the Host system.
Take a look at Bone Dry and DRYCARPET ( AMERICAN )
Now these people are in, or developing their own markets by concentrating the consumers minds on the advantages and benefits.
On Tuesday, I was asked to clean carpeted areas in a new - open 3 months - car showroom and went along with my Texatherm, which is normally brilliant on commercial carpeting .............not this time, because the carpets were very plush 100% wool and the cut pile was prolific.
The Ninja did the job perfectly, but on this occasion the Host or Klanz would have coped with considerably less setting up / putting away time and almost no disruption within the working environment. This would have allowed me to complete the job at an earlier time and the sales manager would not have to stay behind for an extra hour.
You will certainly need h/w/e, unless you're prepared to walk away, a lot, or become a very good marketer !
best wishes whichever route you take
