I cleaned a floatex carpet for the first time yesterday. I was light brown, dirty and looked well beaten up. The customer complained it was shedding fibres. It is only 5 years old, and despite the fact it gets little traffic, looked very worn.
I cleaned it with Split-X. It cleaned up ok. I extracted lots of carpet fibres, and had to bale out my HWE by hand as it was blocked up with the stuff. After the (thorough) clean it still shed fibres.
I suggested to the customer that they went back to the manufactured to check the warrantee.
I though floatex was indestructable!
