I went over it 3 times.
To you and other posters to this question, the carpet was laid about 10
years ago and is quite an expensive Axminster carpet. Over the years the
pile has gone a bit like a woolen sweater that has been washed the
wrong. It has gone flat.
I am not looking for a machine that will bring the pile back vertical,
but a method that I can use.
It doesn't quite answer your question, because it specifies a machine; -
but, the Carpet Cleaner (shampooer) Vax Rapide XL does precisely that. The
machine which shampoo's the carpet and vacuums the solution off, then
permits rinsing with clean water -and sucking that off
leaves the carpet clean, dry and with the pile upright!
It achieves this by having two contra-rotating powered roller brush-bars.
The two bars have the effect of 'up-righting' the carpet.
We've tried it on a stair carpet -about six years old- the carpet had been
definitely flattened over the years. After the machine had done its bit, the
pile was as new!
Make sure you "look" at the correct model ;
'Vax' has a bewildering range of models; all with only minor variations on
the naming;- Rapde; Rapide Super; Rapide XL etc. etc. But there are a large
number of variations in the 'fit'; some require the cleaning solution to be
pre-mixed; some have only one brush-bar
The model we bought has a pair of contra-rotating brush bars - each bar has
two spiral brushes which screw the brushes into the middle >>>>><<<<< (sort
of] where the suction is effective.
It also has three tanks- one for cleaning solution; one for clean water [it
mixes the appropriate solution] and a large capacity 'dirty-water'
I can't claim for the efficacy of the other variants - I know some have only
one brushbar. We couldn't find the model in the sheds so eventually
purchased it -sight unseen- from QVC.
Actually, we saw it on QVC; decided we'd like to see one and trogged off
around the sheds: but none of the usual suspect stocked that high end model.
It wasn't cheap; but compared to the value of the carpets in the house I
'gambled' on the stair-carpet (particularly) lasting another year. -IMHO
it'll now outlast me!
What I meant by this post is that both soil extraction cleaning & the
addition of a power brush - which is what the Rug Doctor does - should have
raised the pile. Wool is a naturally resillient material, which is much
better than synthetics when it comes to shape retention.
If the Rug Doctor with its power brush didn't raise the pile I'm at a bit of
a loss - after being into carpet cleaning for 30+ years.
I can only think that previous cleaning has left a residue or that there is
still heavy soiling in the pile. If I were still cleaning carpet I would go
over it again with an acidic fibre & fabric rinse.
