The EWK can be connected to a compressor to create suction (not sure that the Schwaben has that feature) and I like the dimensions of the EWK for stability i.e diameter to height ratio.
When I drained the 70 gallon fuel tank in the boat, I used compressed air and it made it quick and easy to extract something like 30 gallons of fuel.
The Schwaben has the air-operated feature on the 6L but not on the 10.5L. For normal transmission fluid, differential fluid, and engine coolant on passenger vehicles, is the air-operated option worth it?

Probably not, but I like having options, and that feature was awesome when I emptied the 70-gallon fuel tank in the boat. There are other ways to empty a fuel tank of course such as a 12V pump, but this was such an easy way to do it. I connected the EWK to the fuel line that ran to the original engine, opened the valve to allow compressed air to flow, and it took less than a minute to fill up the 10 liter container. It took a lot more time pouring the case into 5 gallon containers so that I could use it in the Jeep.
