Fits Shark Navigator NV22LWM although this model is not listed as compatible. The reel was exactly the same length and the bushings fitted perfectly. The only problem is that the white gear is upside down. The edge/guide (red arrow in image) is on the outside edge of my NV22LWM, while in this video it's on the inside. The webbing was tight between the two darts but I managed to get it to work. I'm not sure if the teeth actually mesh or if the belt is tight enough between these two guides to turn the pulley. Anyway, now my brush head is working great. It was clogged and the bushings burned out due to dog hair. Much cheaper than spending $80 on a brand new brush head.
