This part is an exact replacement. It fits the old version of the Hoover Linx Wind Tunnel handheld vacuum and works great! I LOVE LOVE LOVE my Linx Wind Tunnel; I've had it for over 7 years and this is the first and only problem I've encountered. You can't find this model anymore ๐ข and this part saved me from buying a new vacuum cleaner. The ONLY difference with this replacement part is the spacing between the 3 side bristles of the brush. One piece of advice: be sure to orient the "square" at the ends correctly when you put it in the vacuum. At the ends of the brush there's a matching perfect fit - semi-circular shapes - that you need to line up and snap into place (think: like the pieces of a jigsaw puzzle come together).
