ResolvePet Hair Eliminator Carpet Cleaner & Vacuum booster, peppermint 18 Oz (Pack of 1)

Does the carpet need dry time after the spray and vacuuming? Or is it immediate dry after vacuum?

does this fit in the carpet cleaner stick?

Does this leave a ring around the area you have cleaned? like, is the spot clean but there's a residue of the stain around the old spot?
