Me too. These with the original 1100w Nilfisk industrial 2-stage motors are my favorite. Now very hard to find. They are BIG motors and best performing. My GS90 has 1200w motor which is much smaller, but still performs very well. Just 88 cfm to 82 cfm decrease compared to the industrial motor. Tone of these motors is completely different. Small is shrill and big is smooth.
