Has any one had the experience of removing crush marks with the cimex?

Some swirling and marking in the carpet from the movement of the pile is normal, especially with cut pile and longer loop carpets. In fact we can expect to see some pile distortion from any machine that produces agitation including the Cimex, Rotary, OP, Cylindrical Brush, etc. The Cimex scrubs the fiber from all sides, so it produces a lot of agitation. The marks will disappear after post-vacuuming and some normal foot traffic. We tell our customer that the marks show that we've thoroughly scrubbed their entire carpet and the marks will disappear as the carpet gets walked on. It's never presented even a minor problem with any of our customers. If you had a reason to try to remove the marks, the carpet could be groomed while it's still damp but that would add a considerable amount of extra labor. So my advice would be to educate the customer that the markings show where the scrubber has seperated and scrubbed the tufts of fiber (a good thing) and that the marks will disappear in a couple of days.

Hi Michael, this subject can be a bone of contention with many carpet cleaners.

In my opinion, and experience, most synthetic carpets when they are crushed, be it from furniture sitting on them, or any other heavy object, can be permanent.

I liken a strand of carpet fibre to a spring.

If the spring is overtensioned, it loses it's ability to regain it's former tautness. Instead of being a tight coil, it will be fairly loose.

I believe that synthetic carpets also have this 'tension' effect, some may call it a memory.

Once it has been crushed, it loses its ability to stand up as it previously did.

Some have said that by putting a block of ice on the crushed area, it will come back to normal, and a hundred other anecdotes.

I have seen 'crushed' carpet extracted and groomed, the carpet has 'stood up', as soon as someone walks on it, the fibre is flat on the floor again.

Wool, is a natural resilient fibre, and, as such, withstands crushing much better, although it also can be permanently damaged by the same crushing over a period of time.

Hope this helps answer some of your question.

Cheers,

Shorty.

i was under the impression Michael is asking if the Cimex can remove crush marks...not that the Cimex left crush marks. am i off here Michael?

thanx --- Derek.

BTW, as Shorty pointed out, the "swirl" marks left on some carpet is a bone of contention among CC'ers, not among clients (least from my limited experience).

I was refering to removing crush marks from a brand new install often time i am called by a carpet manufacturer to remove these marks. On nylon I have traditionaly used truck mount steam but on poly carpets I am having little success because poly being hydrophobic in nature rejects the steam process.

Michael,

I misunderstood what you were asking.
Looks like Derek hit the head on the nail. Ouch!

I don't have any experience trying to remove crush marks with the Cimex.
Why not give it a shot and let us know what you discover? Thanks.

in most cases you will need high heat or steam and a brush or groomer to remove crush roll

I know I'm late here. If you use the Cimex try it with brushes instead of pads. The brushes will stand the fiber up.
