Horses for courses,
I use a tm and portable, A tm is not the one and only machine you need, but it will clean faster and better than any portable, and I hope no one will argue with that, but you can't clean a sissal carpet or belgian wilton with a truck mount, you can't clean a carpet up a tower block after so many floor, you can't clean a carpet in a house when you can't park near that house either cos you can't park on the house side of the road or it is too far away and is not worth the hassle. If you can't clean with a tm you use a porable instead.
You can use a tm to do a large commercail jobs, large houses etc, quicker and better than a portable. As most tm owners will tell you the hourly rate you make is far highjer than with a portable. Argue this you may, but all you argueing don't have a tm, do you.
Do not buy a tm if you can't afford it, or do not have a large client base, cos they are expensive, but they don't break down as often as portables and you don't have to replace the pumps and vacs every year, so big outlay, cheap running costs.
As for all those negative thoughts over the last 3 pages, I had all thoses before I pruchased, ie. dirty hoses, someone stealing the van, people tripping over hoses etc, has anyone every read a post on this site were one of those negative thoughts has happened. No, then maybe cos they don't.
Every been and quoted a massive job and never got it? Maybe one of the other quoters told the enquirer about his tm and its benefits againist a portable.
Worth thinking about,
No actually its not, please carry on using your portables, and .....................................................
