I'd already bought the product before reading the reviews on here but went ahead and tried it anyway.
The carpets in our flat weren't cleaned before we moved in and they're pretty old as well, but I gave this powder a go on an area of the living room carpet (cream coloured) and it came up pretty good.
I left it on for about an hour and scrubbed it in thoroughly. I know it says 20 mins but I can't see how that's enough time to work.
I wasn't expecting it to bring the carpets up like new as I suspect some others were, but overall it certainly rejuvenated that area a bit and it definitely looks cleaner.
It hasn't harmed my vacuum cleaner thus far either.
I'll be doing the whole carpet with it and will give it a second going over :)
