CXL and MG
The CXL was made by interstate engineering it used a two stage ametek motor in it it's cord hooks are on the top of the machine, the body of the machine (i think) is aluminum, it uses 1.25 tools, it has pigtail connections
The MG series are made by Aerus Electrolux they now have a one stage fan i'm not sure of the brand, the cord hooks underneath the machine one of the hooks swivels for quick release, the machine body is aluminum, It has an electrolux power head, it's direct connect and the tool set up like the new Guardian Ultra, it's different from all other models of electrolux and will not accept tools from the Epic, renaissance or guardian It has an after filter similar to the ones found on the plastic bodied machines.
As i said in terms of airflow the CXL is significantly more powerful than the MG2.
The MG2 is quieter than the CXL, but i do not have the post motor filter for the CXL
