Review on 🗑️ Dirt Disposal Bags Replacement Parts for iRobot Roomba j7+, i3+, i4+, i6+, i7, s9 Clean Base Robot Vacuum Cleaner - Pack of 12 (4640235) by Karen Gupta

They do not fit our Roomba i4+ 4552 as advertised. The opening in the bag doesn't seem big enough and the lid doesn't close/close either. I saw another reviewer reporting the same thing. So if you have an i4+ I would skip this one. Now Roomba can't be used for a few days while waiting to get really good bags. As always, we had a first class return experience with Revain.
