Are vax 6136 orange cylinder carpet cleaners any good??

Question:I am watching a couple on ebay, which are finishing tonight.
Does anyone have one and how good are they?
My light carpet is heavily stained with spilt juice from my 3 yr old and heavy traffic through my lounge( dirty shoes )

Answers:
From experience in the domestic cleaning trade... I would say that yes they are good to begin with, as are most of these so called carpet cleaning hoovers etc. From my point of view Henrys are the best on the market and you can get a henry that will clean and hoover carpets and floors, suck up spillages etc. Look for industrial type Henry...can get them cheap on ebay etc.
Good luck.
