I only cleaned once, the carpets definitely looked better and the water in the waste tank was dirty but I could still see some traffic areas so probably just need either more pre spray or better agitation or maybe both.

Just remember that you cant always get traffic areas, especially if heavily soiled, looking like the less worn areas of carpet. The traffic lanes will have less pile due to wear and deterioration and so will not reflect light as well and will always look different even when absolutely clean.
