Fluid Extractor Suggestions

HF has a bunch of models.. including the one I have: 6gallon you use with air compressor.

Admittedly I only use mine to extract. But, you can either take the top off and clean it out, or (and I think this is what I would probably do), suck some clean fluid (that you will be using to fill) swish it around the container then empty it. What little remnants remain won’t hurt a thing.

I was thinking that (using the new fluid) and then pumping in the new stuff after.

I used it today to suck out my transmission fluid and it only took out 3.2L of 7.7L (says Service fill is 5L) I didn't make a mess at all, but it took out very little fluid no matter what I did I took the top off after to clean it out...
