I recently bought a Kirby vacuum but I have a G10 model that predates the new Kirby Sentria. Even with new or old models, they all rely on the same base. So if you are wondering if this will work for your Kirby. Yes they fit all Kirby systems from old to new and this is a necessary part because without this part your Kirby will not make the foaming soap you need to clean carpets properly! So I hope this review will help you.
