http://www.lawnsite.com/showthread.php?t=338568 sorry it is a link and was too lazy to resize just to repost. what do you think magna matic?? nice huh!! i used it today and it was very smooth. completely different from the old Wall rbg on the floor next to it in the pics. the vacuum seemed to really grab most of the debri too, but time will tell how much as once we start grinding daily it will become evident what the vac could not get.
