Electrolux vacs are known to shut off automatically when bag is full. These bags repeatedly turn the vac off with a false reading of a full bag. When you check the bag it is not even half full and you have to put your finger in the hole and push debris down in to the bag to continue use. I have to do this at least 3 times per each bag usage. Next time I will pay the extra for the regular electrolux bags. Plus the bags tear very easily. I found this out when I tried to shake the dirt so it would settle, hence why I have to stick my finger inside the hole and push down the dirt.
