Where is the Rainbow and Power Nozzle Serial Number?

Knowing where is located your Rainbow serial number is very important for registering and claiming your machine warranty. Some Rainbow dealers will ask you for your Rainbow or power nozzle serials in order to send a part to Rexair for warranty.

Before to buy a Rainbow

Rexair do not allow any distributor to sell new Rainbows over the internet, so it is almost sure that all Rainbows sold throughout any marketplace like Amazon, eBay, etc is not a brand new unit, even if they describe it as a new product.

If you want to verify before to buy a Rainbow if the unit is, in fact, brand new, or if it was sold before, you can ask the seller for the serial number and contact any authorized Rainbow distributor for information related to this particular Rainbow.

Sometimes online re-sellers are not happy to give you this information because they know you will discover that the Rainbow is used.

In the last case, you can use this video to know where the serial number is and ask the seller to send you a close up picture of the area related.

Check the video below for instruction about to find the Rainbow and power nozzle serial number.

What else can I do with my Rainbow serial number?

If you know your Rainbow serial you can contact us for more information about your Rainbow purchase, like the day of purchase, the expiration of your warranty or even the name of the Rainbow representative who sold the Rainbow to you.

Did you loan your Rainbow to somebody and they give you back a different one? If you have any doubt check your serial number.

If you didn’t record your serial number before to loan the Rainbow, you can contact us to check if this unit was sold to you.

What does the serial number mean?

The Rainbow serial number has two parts. The number on the top is the actual Manufacture Serial Number of your Rainbow while the 3 numbers on the bottom are the Manufacturing Date.

You can read the Manufacture Date in two parts:

  • The first number is manufacturing quarter of the year.
  • Two last number is the Year of the manufacturer.

  1. Hi! I tried using the to to find what model I have but it wasn’t working. The serial number is 20646579

  2. My serial number is 3109966 (299). Shows Model E-2 on sticker inside; e series on canister insignia. Do I have a Gold series?

    1. vladimir leon

      Hi Nikki.
      The E-2 model e SERIES Rainbow divides into two versions, with the second one taking effect on 03/27/00 and bearing the serial number 9280000. The second version features a conveniently detachable rear cover, making HEPA filter replacement a straightforward task. In contrast, the first version requires the removal of four screws to access the HEPA filter.

  4. Hello. My serial number is 21209594. What model is it? I need to replace the water bowl. Is there a particular part number?

  5. Hello, do you happen to know or could find out what the CPT code for the Rainbow SRX (RHCS19) unit is?
    This is for those of us trying to see if our insurance companies will cover our purchase of the SRX unit.
    (Personally, it is already helping with previously diagnosed asthma symptoms, and our doctor already agreed to write a prescription if we can get documents from our insurance. Our insurance requires both a “CPT” and “Billing” codes, to which our doctor provided the billing but informed us that the “CPT” must be provided by the device’s company.)

      Hi Scott.
      I am not aware of any dealer that provides a CPT code when selling a Rainbow. What we do provide with the equipment is a certificate as a friendly system for people with asthma and allergies and also a certified air cleaning to your home environment. The Association of Home Appliance Manufacturers (AHAM) certifies that the Rainbow is a proven air cleaner designed to reduce air pollutants that contribute to poor indoor air quality.

  14. Glenda Whisenhunt

    I purchased a used Rainbow Vacuum E-2 model from a very elderly lady.
    I do not see a model number on the machine.
    How can I figure out what Version is it ?
    I am wanting to buy some accessories, but I dont really know the specifics of what they are asking.
    They want to model what Version 1 or 2?
    1 speed or 2 speed: I think it is 1 speed from what I can tell

    1. vladimir leon

      Hi Glenda. Did you see below the electric cord as shown in the video? Serial number most be there if the Rainbow is manufacture after 1998, if your rainbow is older than 1998 you probably have a SE serie and the serial number will be on top of the intake hole( at front face, where the hose is connected), please let me know if you find the serial number

      1. vladimir leon

        Michelle, your Rainbow model is Rainbow E2 Series Black, so if you need a power hose (electrical hose with the handle and trigger, the one that comes standard with your Rainbow) It needs to be compatible with e2 series Black.

    1. vladimir leon

      Hi Karen, Your rainbow model is e2 series and the manufacture date is first quarter of 2015.

  15. Karen McLaughlin

    I have a complete Rainbow system of cleaning products. What is the Model and manufacture date for my Rainbow with number on power nozzle: 40646617 112

  16. What type of rainbow do I have? Serial #20858501 Mfg date 511
    When we vacuum the machine goes on and off when moving the vacuum back and forth while vacuuming. Is there a switch in the hose that may be worn out for was alway put the switch on hold when vacuuming weekly.
    What part should I be purchasing to replace the switch?

    1. vladimir leon

      Hi Kath, this can be different things, but most common problems are a water basin overfilled or foaming in the water.
      Also there is a switch under the rainbow that avoid the machine to run without the water basin in place, this switch can turn the Rainbow on and off when moving the machine if you do not secure the basin to the Rainbow using the side latched, please be sure you latched the basin before use the Rainbow.

  17. My Rainbow is time stamp 115 and serial number 20864883.
