Don’t ever let them do a demo in your house, I’ll save you the time.
They will show you how your vacuum is not as effective as the Rainbow. They will wow you with the dirt left in your carpet.
They will also degrade you for having such a crappy cleaner and pressure you to pay way too much right now! for their model.
They say one hour, but it’ll be at least 2 hours. They were nice until the very end, after talking about the price when they get pushy and rude.
If I buy a Rainbow, which I still may, I will get one online. The sales pitch was like a 1950’s nightmare.
