Riddle me this, Batman...
Not to stray too far off the topic, but why on earth would anyone want a bagless vacuum? They're all over the place now, and next to "continuous cleaning" ovens, got to be the stupidest idea ever.
Bagged vac: Remove full bag. Put in trash. Replace.
Bagless vacuum: Remove full container. Don't breath dust. Find place to dump it. Find a place outside to dump it. Dump it. Don't breathe dust. Wipe out container. Wait, go back inside to get a rag. Wipe out container. Should have used a paper towel. Shake out rag. Note to self: next time, stand upwind. Clean filter. Don't breathe dust. How to clean filter? Find owner's manual. Decide it's too much work. Go back inside. Replace filter and container.
By the time the bagless folks are done, I've got my machine put away and have my feet up with a martini in one hand and a cigarette in the other.
Okay, so you have to buy the replacement bags, but even I don't think that's going to break the bank, and I'm the World's Biggest Cheapskate.
veg, who doesn't vacuum often. Obviously.
