ASTHMA & ALLERGY FRIENDLY

ASTHMA & ALLERGY FRIENDLY™


ASTHMA & ALLERGY FRIENDLY

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.

The listed price reflects a $150 credit when returning your old main unit. A pre-paid return label will be included in the box.

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.

FACTORY CERTIFIED

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 DO NOT USE GENERIC PARTS OR ATTACHMENTS

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 on the same day.

    "order was replacement for vacuum brought from Rainvac 20 years ago. Customer service was quick to response to questions and resolve issues. Rainbow Vacuum only one we use great."

  • 5/5 By Dianne Hadorn On Aug 27th 2025

    "The machine works amazingly well. We bought a new one in 1994, and I didn't realize just how much the old one had slowed down and was slipping. First time using the new one, it brought back excitement to hear he debris clanking as it went through the metal attachments. Refurbished but works amazingly. And the process to order was simple and quick"
