I can't get an XV-15 but I did get an XV-11 from Amazon
and an XV-12 from Target. The only difference other than the color is I did notice a tighter fit of the orange holders on each end of the cleaning brush. Much more force is required to remove either end of the brush vane retainers on the XV-12 model. The pictures in this post are in the .gif format, to view both pictures just click on the image. There is a 5 second delay between images.
