I noticed a big crack in the hose so I ordered this one. Some reviews said it fit my vacuum cleaner, others didn't. I took a chance and ordered these. I watched a youtube video or two and it worked. One thing about installation is that the nozzle hose is threaded so you have to twist it right to tighten and push like crazy to start it. Took me about half an hour to take it apart, swap out the hose and put it back together. It's amazing that you can get something like this on your doorstep in a day. Anyway, I changed the filters too and it's like having a new vacuum cleaner! We wish you every success with your sweepers!
