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 need to be back in action quickly, replace the main unit with this fully refurbished Rainbow. We can include a return label for your D4 or D3 model Rainbow for credit towards this purchase.

The D4C is a smaller unit compared to the D3 with fewer parts and less chance of wear. It offers increased performance with decreased size. With less parts, there is less chance something will fail.

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.

    "We traded in a D3 main unit that needed the motor replaced for a refurbished D4C. The D4C from RainVac functions perfectly and all of the D3 attachments, water pan, and wheels work as well. Could not be happier."

    "The unit was nice. It replaced a 20+ year old unit that only recently stopped running. Suction is better than the old one, but it has a high pitched whine from the motor. "
