it works. that's how you know.
Actually, they redisigned them about a year ago. The center cyclone chamber is about 5 in high. If it's the older style, it's about 10 to 11 in high.
i have one of each and there is a major difference, the new one puls out about 3 times more than the old one. i have to get a dremel and cut the old one down to size.
sebae0,
Actually you can pull out the large inner tube with a pair of long needle nose pliars. It does take some wiggling but it does come out.
Then just use a fine tooth saw.
