You need to rinse more until the water runs clear and wash the back of the rugs! With your scrubbing and the foam your videos would be perfect if you just did that
You work really hard at cleaning these rugs friend. Now that you have a bigger workspace and a squeegee you need to work on making your wash bay clean. It's pretty dirty, but you are improving with each video 🥰 and please wash the back of the rug.
