Let's talk about... Zippland iRobot vacuum bags!THE GOOD:1) The bags WORK!2) These bags are much less expensive than the comparable product offered by iRobot3) The bags are easier to install than the iRobot branded version4) The "trap door" flap design of the bag intake is a step above the "slider" design of the iRobot bagsTHE BAD:...Nothing yet!THE IN BETWEEN:1) The plastic component of the bag is somewhat flimsy, but that may just be a "get what you pay for" sacrifice to make.----------I have to admit when I first pulled these out of the Amazon delivery box my initial thought was, "I didn't order diapers..." Needless to say, the packaging doesn't immediately make it clear what you are looking at, but once you get these bags out of the plastic all is well!At first, it is apparent that the design of the bags is somewhat different than the comparable iRobot branded vacuum bag; however, the design of these bags is actually an *improvement* over the iRobot design, in my opinion. Instead of the annoying "slider" panel controlling the intake port on the iRobot branded bags, these bags employ a flexible, springy soft plastic trap door that opens when the tower motor produces suction. When the motor is finished, the door seals itself back up... Altogether brilliant!On top of that, the absence of the "slider" panel makes these bags easier to install than the iRobot version. The annoying problem of the the "slider" panel getting caught on edges and preventing installation is no more... which I love!After installation and running my vacuum for the first time, I see no issues with these bags. They appear comparable to the iRobot branded bags in terms of fabric thickness and they are equally sized, as well. Additionally, they are substantially much less expensive than the product offered by iRobot. For less than $30 I now have enough vacuum bags to last well more than a year!THE VERDICT:If you have an compatible iRobot tower for your Roomba vacuum... Get these bags! They work, they are easier to install, the are better designed, they are of comparable quality, and they are inexpensive! It's a no brainer, in my opinion.

These are NOT compatible with the irobots. I have both a J and an I and it worked with neither

Brought the roomba i7plus and there was no cord so couldn’t even plug it in…brought these bags at the same time and could only leave a review in the bags and not the actual roomba

I keep getting bag missing error does not empty.
