They can be cleaned and reused, but they can clog so badly that cleaning is impossible. Given that fact, it's a shame that the only suitable replacement available is almost half the cost of the vacuum cleaner itself. It must be a $10 item. But it's still cheaper and less wasteful than buying a brand new vacuum cleaner, but your vacuum cleaner will work like new again. So. I give the product itself 5 stars, but I deduct 2 stars because of the overpriced price.
