Tried it today on 3 jobs 2 T/L and a large rug.
I actually quite liked it, it is harder to use than a glided wand but I turned the revs down on the TM until it was just ticking over and it still cleaned well.
My son remarked that the carpets were noticeably drier, he used his trouser knees as an example, he said they were slightly dampened when he knelt on the cleaned carpet to place the protective foils, usually they would be very damp.
If I used it all the time it would probably save me £25 a week in fuel
