These bags look exactly like the famous brands' bags, made of the same material and thickness. The only difference is that branded devices have a plastic frame and a sliding cover around the hole. They have a cardboard frame and a hinged lid. Brand brands have a longer rubber pad inside the hole. These bags have a thin rubber seal. No negative difference in how my vacuum robot removes the accumulated dust/dirt. I have two large dogs and almost all floors are carpeted. I will continue to buy these bags in the future.
