I'm sorry I can't help but your post reminded me we were just talking about carpet sweepers the other day...

We recently bought a roomba and I was saying to my H how the next generation of kids might not even be very familiar with regular vacuum cleaners. You know, the odd house might have one but you would rarely see them... same as our generation with carpet sweepers. He replied "what's a carpet sweeper?"

Good luck tracking down a good one!
