I had a Kirby -it was hard to switch the heads. I had a Rainbow and it needed a new on/off switch within a year. Now I have had a Hoover Windtunnel for a year. I like it. It has red/green lights that show if floor is dirty/clean. I just vacuum until the green light stays on. Attachments fit right on it. There are no bags. It is fairly lightweight. So far-so good.
