Been using Texatherm for some 4 months.
For large areas it's a must, so much easier and quicker. For smaller areas such as 2 bed semis etc can be hard work.
Stairs and furniture..forget it. I still get out the hwe system for these.
You won't see this in the sales lit but for some marks/stains I use the spotters normally used for hwe and then texatherm them up.
IMO it is great as a maintenance tool (ie regular cleaning) not so hot on the nasty mess we sometimes end up cleaning.
On the really big side, customers LOVE the 30 minutes and dry.
