Yellow bristle brush; headlight...
Thanks for the great comments! In response to Durango, I do like how the replaced yellow bristle brush grooms my carpets as opposed to the old plastic brush (almost approaching thr grooming value of my aluminum non-beater bar brush I have installed in my Sanitaire Blue Line S645). Eurekaprince, I have found, that though there is a headlight on my Blue Anniversary Edition, it doesn't come close to the brightness or illumination-value on my Windtunnel Lite. I have further noticed build quality concessions on my Blue Self-Propelled...which is disconcerting...aiming at the overall cheapness factor that has emerged amongst such a pioneering and ubiquitous brand that Hoover is.
