Actually, I have keep the E upgraded throughout the years. It has the wet pickup electric hose, as well as the current Aquamate. I also have the Minijet for it. The power nozzle is…not so impressive…and I had the sole plate crack on me the other day, so that’s getting replaced.
I think the itch for the new Rainbow is similar to the itch for a new car. I also think the new Kirby Avalir in blue is quite stunning but I have exactly zero need for that-my house is mostly bare floors and rugs. A canister serves a much better purpose (plus when I vacuum, I go around the baseboards in every room, clean the chair rails in the room, etc).
