These reels do not have a magnet installed in the reel head. I only found out about this after installing it, and my Orick XL turned itself off after 3 seconds. A quick call to Orick customer service and they asked if the new roller brushes have magnets built in? No, they do not have. I had to drill magnets out of old roller heads, drill new holes in new brushes, and glue/reinstall the magnets. What a pain in the back but I don't have time to return it and get a new set. I want my vacuum cleaners to be up and running as soon as possible. The manufacturer should make it clear on their website that these brushes will not work if you have the magnetic sensor disable feature on your Orick XL.
