Woolite Heavy Traffic Foam, 22 Oz, 0820

I want to use this on my multicolored area rug (black, blue, white), will i be able to use it without the colors fading or ruining?

what if i want to clean the whole carpet, like 4~5 door mats size, is it gonna take forever to dry?

Is this the refill for the rug stick carpet cleaner?
