This is an awesome kit that will give most backpacks the ability to use electric power nozzles. Electric power nozzles are much better than turbine nozzles for several reasons. First, turbine nozzles use the airflow of the vacuum to spin the turbine fan, so they decrease the airflow that is used for cleaning. Second, they are much louder than electric nozzles, and third, they clog very easily because they are designed to channel all of the air to go through the turbine. There is really nothing but advantages to using an electric nozzle, but surprisingly, most backpacks do not include them or even an outlet to connect an electric nozzle. Not only does this kit include a very good electric nozzle, but the connection is standard, so you can use other nozzles as well. To use the kit, connect your extension cord to an outlet in the usual way. This kit includes an adapter that you plug your extension cord in to. It then provides two outlets, a regular one where you connect the backpack's pig tail cord, and a smaller one that the electric hose connects to. At this point, insert the hose in to the top of your backpack and you are ready to go. The hose end is a nice gas pump handle, it's very similar to the end used on Plastiflex central vacuum hoses. It provides a standard 1 1/4 connection for attachments and a standard two prong mini receptacle for the power nozzle connection. The power nozzle that is included with the kit works very well, I have also tried it with the power nozzles made by Sebo, Lindhaus, Riccar, Wessel Werk, Eureka and Centec and it works with all of them. If you use a backpack vacuum and are cleaning carpets, get this kit, it will enable your backpack to clean far better than using the straight suction carpet tools. I can't think of any changes I would make to this kit, other than to perhaps mention in the description that it will work with any power nozzle that has a cord on it. There are two backpacks that I know of that will not work with this kit...
