I used this vac twice when the button on the right side to keep the bag closed came off. I called the store and even though they had one in stock, told me they would order a replacement since they couldn't tell if it was a defect or user misuse. REALLY?? They're called "buttons", you turn them to open the bag and turn them back to reclose the bag. I don't even allow the bag to fill all the way because it's so big it's hard for me to empty if more than 3/4 full. The 3rd time I used the replacement bag, the same button came off again. The replacement bag cost $151.68 (billed to the store) I can't afford to buy replacement bags every 2-3 times of use. I'm considering returning the whole thing but now I'm told they will charge me a 15% fee (97.50) to return defective equipment. Very disappointed!! If they could fix the bag issue it would be an awesome machine.
