Do I love it? Well, I can't say I would save it if the house was burning down, but it can really suck up the dirt in our lives (amongst various other items: cat toys, toothbrushes, legos, socks, marbles, etc). That in relation to the age of the user and that they didn't want to actually bend down and pick up the item. That lesson is for another day.
I must say, they aren't cheap, but this is the only vacuum that we've ever owned. We have many of our friends purchase 2-3 vacuums in their lives, but (knock on wood), ours has been great. We've only had it worked on a few times (it will probably go out tomorrow) to replace the belt and roller beater. We got it right after we got married, almost 20 years ago and took the plunge because of the great features to help with allergies and getting rid of all the junk that settles in the carpets, floors and furniture. Now that we have indoor critters and live outside of town, we find that it is even a better help with country air dust, pet hair and dander. If your cat will lay still like ours, we use it to suck up the lose hair from her. I've used it to clean our ceiling fans, upholstery, and some quick dusting on tables and picture frames (yes, I own dust cleaner and rags).
All of the dust and junk from your floors, carpets, furniture goes directly into a water filled basin without any hope of swirling back into the atmosphere when you empty it, like with a bag or up right canister. It was a little horrifying at first to see all the junk we had been living with that collected in the basin, but we quickly realized that the more in that got sucked up into the basin, the better for us.
I know it's a strange thing to love, but there you have it, I love my Rainbow!
