Question: Is there a warranty on the rebuilt vacums?
Document: This is a very old model, they don't make these anymore. You don't get the original 20 year warranty, as Rainbow NEVER sells any of it's products online. Watch out.
Back when I was in kindergarten ... 1987!!! It has been threw he'll and back, and this things is AWESOME!!!! I just had it rebuilt for them, as they have 4 dogs 6 cats. And it works just as it did one day 1. You can not find a better vacuum cleaner.Sure changing the water can be nasty since it's dirty and nasty. But your carpet will thank you for it!,
I love my rebuilt Rainbow vacuum cleaner! It works great, love the power it has. I have a lot of sandy soil bare spots in my front yard and it gets tracked in. All my old vacuums of the past couldn't pick it all up but the Rainbow does. It just has a hesitation in th power switch and it doesn't always cut on the first time.
this vacuum beats all others. i have no dust left lingering in my house. the item arrived well in time. i recommend this to any one looking for a new vacuum.
juat like the one i wore out several years ago. only wish there was a pet hair attachment with it.
This is the Best cleaning system you can get. Instead of a dry, messy vacuum bag, or a dry receiving tank, this vacuum uses tap water to KEEP THE DIRT IN THE VACUUM. Yes. It is the most complete &#34;clean&#34; I have ever had in my life, and I am no Spring Chicken! When you get through using this system, you empty out the most vile dirty water and it feels great!
The rainbow was just as I remnered growing up. Left the floors and the air in my house feeling clean!!! Have had many vacuum cleaners since owning my own house but none ever matched the quality of the rainbow.
Thanks for such a great product rebuild. Plenty of hoses and everything was crystal clean and new-looking. The vacuum works beyond belief. I took a room I had vacuumed and cleaned a few hours earlier; hardwood floor with a throw run and the vacuum found a lot of dirt. (The room looked clean before; I could find no dirt.) I cannot wait to clean the house now with my supercharged vac.
Most, no ALL other vacuums will tell you they have &#34;hepa&#34; filters and such, but the air in those vacuums STILL has to filter through the bag or something and comes back out with  the finest particles of dust/dirt, putting it right back onto the floor of your home;  This one, however, sucks it up and down into the water, where IT STAYS. Love it . Love It! Worth every Penny!
Love this vacuum. No dust to deal with when trying to empty dust containers. I have allergies so this helps me; vacuum received in excellent condition, Happy customer. MML
Answer: Great Question :)    So at Greatvacs we do things a little different.   We have rebuilt almost 20,000 Rainbows and are experts on them.    We only buy good Rainbows and even though they run fine we still take them apart, clean them and rebuild them to like new condition.    We do this so they qualify for our 5 year warranty and our 30 day money back.    So yes when you buy a Rainbow vacuum from GreatVacs it will come with our 5 year warranty.    The warranty covers both motors, all bearings, and the fans (pretty much all the moving parts).Thanks DustinGreatVacs (Seller)
