Review on 🔧 Enhance Your Shark Navigator Lift-Away with the Power Sonic Vacuum Cleaner Brush Roll for NV350, NV351, NV352, NV353, NV42, NV22, NV31, NV70 by Dominic Maxwell

My UV440 model. The Shark site does not have a replacement brush for this model. This one was similar so I ordered it. It installed perfectly and works great. No problem. The lower part can be easily removed during assembly (using burglar-resistant Torx screws). If it doesn't come off easily, you haven't found all the screws. Youtube is your friend. One pair is under the front wheels that need to be removed and another pair is hidden. You'll understand when you find them all when the bottom just comes off. When you put it on again, the same thing, everything goes smoothly. If it isn't, check the wires to make sure they aren't pinched. I tried to collect it again and figured it out. When I had everything in order, it just came together with no problems.
