It still has the same properties as any other polypropylene carpet. Stains remove well, still crushes and mats like olefin. It holds up slightly better than some olefins, but I don't have much hope for it.
One of the beach houses I clean just had it installed, the owner told me how he took a sample of it from the store and poured bleach, bbq sauce, and red wine, in different spots on it and left it over night, rinsed it in the sink the next morning. No stains or color loss!
