Here's a surprise (shock?) from a Hoover guy......
Yes, the door pops open and the the bag comes out when it is 'time to change the bag'. Yes, I KNOW this!! lol I have friends who love Electrolux. I have a friend in Philly who was very ill after surgery a few years back. I offered to clean his house for him. All he had was a gold electrolux with a powernozzle. Yep, I cleaned that whole home with it. The minute it was turned on, thatbag popped out. I thought that was clever , a cute feature, if you will. So, he changed his bag, colostomy, and I changed the vacuum bag. THe vinyl braided hose was worn to bits. He FINALLY had that thing serviced.
As far as bags go, I ALWAYS use GENUINE filter bags.
