There is a big difference between recovering the refrigerant and evacuating the system. This method will work well for recovery but evacuation should be done with a system that can pull a deep vacuum.
A working system will contain lots of liquid refrigerant. A rig like this should be able to remove all of it, then pull gaseous refrigerant out down to a very low pressure. There will be a very small amount of refrigerant remaining. No big deal. Just remember a couple of things:
1. Use a large enough recovery tank
2. Do not mix refrigerants (unless experimenting/hacking)
3. Be safe
