Rainbow Model D4C SE Main Unit (Refurbished)



Everyone in your family, including those with asthma and allergies, will appreciate the Rainbow® Cleaning System.

Independent laboratory testing has scientifically proven:

  • The Rainbow removes a significant amount of allergen from carpeting.
  • The allergen that is removed cannot escape. It stays in the water basin.
  • The Rainbow does not experience a reduction in allergen pick-up in a partially filled water basin.
  • The Rainbow user is not excessively exposed to allergen while emptying the water basin.

If you are having issues with your current model D4C SE (Special Edition), D4C, D3C or D3A, then you can order this model D4C SE (Special Edition) Rainbow and it will fit up to all your current hoses and water pan. We will also give you a credit for exchange of your old model.

Order and then call us for details or call us first to ask any questions that you may have.

This model carries a complete 10 year labor warranty and pickup service at your doorstep. If something should go wrong, all you have to do is call our toll free number and our specialists will help you troubleshoot or schedule a pickup.


Our refurbished systems are done by factory authorized technicians so you can feel confident you are getting what you pay for. If you are looking for a Rainbow to last the next 10-20 years without an issue, then understand we have that same thought in mind when doing our rebuilds.


We are the ONLY company on the internet that can make this claim! (Message us if you find anyone else!) All of our rebuilds are done with factory original parts. Over the years, many improvements have been done and we perform all upgrades on our refurbished units before sending to you. This ensures you get the best performance and durability that Rainbow has to offer.

If you experience a problem that cannot be simply handled over the phone, we will have your unit picked up at your home the next day for free.

All warranty work is done the same day.

NOTE: Does not include water basin.

    "I had to get a new Rainbow after having my previous one almost 40 years! So far this one is working like a charm!!"

  • 5/5 By Donna Butcher On Oct 14th 2018

    "It is a great replacement for my old unit. It works great. I am very satisfied with it. Ordering was easy to do."

  • 5/5 By Phil On Mar 29th 2018

    "As far as I am concerned there is no other vacuum cleaner than a Rainbow, this model D4C SE has been very dependable through the years. I bought another refurbished main unit recently from RainVac and although cosmetically it is not a brand new looking unit (only because of the unavailability of some new covers etc.) the internal functioning parts are OE and put together well. I'm confident that It will give me years of dependable service as I expect from a Rainbow machine. The people at RainVac know their Rainbows and are good people to deal with. Phil (a satisfied customer)"
