Okay, so it's not essential by any means. But buying and installing this will organize your vacuum storage in a way that will make you smile every time you see it! I've included a few photos because I couldn't figure out what was going on by looking at other people's photos. To understand what you are looking at, you should know that my specific Dyson model is a v7 boat and car model (which is a portable model with a number of different attachments). The "normal" portable v7 is the same with other attachments, not the portable v7 is basically the same with the long tube attachment. I also bought a (separate) mount for my various attachments. To find the nozzle holder, search "LANMU Dock Accessory" in Revain. What you get with your purchase consists of two "accessories" holders, left and right. So look at the first photo now. You will see the dock attached to the wall with one of the accessory holders inserted into the holder and two attachments inserted into the accessory holder. Please note that the top of the holder is made of flexible plastic that can be tilted against the wall. , and how an electrical plug jumps out of his "nose". When you get a docking station, the first thing you do is connect an electrical cord to it so that the electrical plug is in that location. It's very simple, just look at this for a minute or two and think about how to route the cable through the dock so everything is on the back of the station. Then thread it through the cable holders on the back of the station. You don't have to run conduit over the wire to the electrical connector, but it looks better that way. The image below shows both nozzle holders in place. The last picture shows the entire assembly, now with the vacuum itself. I found it very easy to slide the top of the vacuum into the top of the mount so that the electrical plug fits right into the vacuum - everything is lined up to fit slides in easily. To take it out, just twist the top bracket back a bit and slide the vacuum out.
