I have one of the Bissell powerforce bagged vacuums. I have abused it, and it just keeps working. I buy bags to fit Hoover vacuums (type Y or Z) because they are too tall, and unfold the top to dump them. Then I duct tape the top and use it one more time before tossing it (when there is a lot of larger debris). I relegated it for the very nasty carpets since the filtration isn't good even with new bags anymore, and the brush-roll is worn down to near nothing, and use a Sanitaire for everything else.
