I hate vacuuming, I hate changing bags, I hate changing filters! But do you know what happens if you don't change filters and bags? The vacuum cleaner motor burned out. This happened to my friend. Apparently her owner's manual didn't mention regular maintenance like filters (that's the story she told me, anyway). My operating instructions often talk about filter changes. So Eureka lets you come and go. Once you've shelled out for a car, you should be spending money on filters, bags and belts…
