12 Pack Vacuum Bags for iRobot

I acquired these for my S9+ Irobot Vacuum. and they seem to be a good quality material, although the mounting flange configurtation is quite different from an OEM bag as noted in photograph. The mounting flange appeared to fit into the slot in the machoine quite nicely, but the indicator light omn the fornt of the bin was red and after reinstalling the bag several times the light remained red. I was disappointed to learn that the auto emptying vacuum function of the S9+ machine did not recognize these bags and would not function. The bags seem to be manufactured well and will obviously work on some of the other listed models.
