Rainbow Cleaning System Guide: E2, SRX and Add-Ons

6 models on the list November 2, 2026 8 min read

Every spec and price on this page is quoted from the Amazon listing for that model. Scores are out of 10, based on listed specifications and buyer feedback. Nothing here was handled or measured by us.

A Rainbow cleaning system is a canister vacuum that pulls dirty air through a water basin instead of a bag, so dust gets trapped in water rather than pushed back into the room. For a gaming den full of fabric chairs, rugs and dusty cable runs, that approach is the main draw. The real buying decision is which unit to get, since most options on Amazon are renewed or refurbished Rainbow machines, and then which fragrance to put in the basin.

This article covers six products: a complete canister kit with attachments, a renewed Rainbow E2 Black Type 12, a refurbished Rainbow SRX, a genuine Rainbow and RainMate eucalyptus fragrance, and two deodorizer concentrates. We want to be honest about those last two: they are third-party products from Kleenovate and Fragrances Limited, made to work with Rainbow systems, not Rainbow products. We compared listings and specifications rather than cleaning with each machine, and the listings disagree with themselves in several places, which we point out.

Best for
Buyers wanting a full attachment kit

Pros

  • Crevice, upholstery and floor tools
  • Metal wands, reinforced hose
  • 5-quart water capacity

Cons

  • Brand listed as Generic
  • Model and color unclear in listing

The Rainbow Power Nozzle Canister Vacuum Cleaner System is sold as a complete cleaning kit. The listing describes a water filtration canister with metal wands, a reinforced hose, a crevice tool, an upholstery brush, a floor brush, extension wands and other specialized heads. For a room with a couch, a gaming chair and hard-to-reach corners behind a desk, that attachment spread is what you want.

Specs list a 2.5-quart capacity, 2 speeds, a 12-inch cleaning path and a noise level of 78 dB. There are clear inconsistencies, though. The brand field says Generic, the title says black and gold while the color field says blue, and the listing never names the Rainbow model. It also does not say whether the unit is new, renewed or refurbished. Ask the seller before buying if the exact model matters to you.

This option suits a buyer who values a full accessory set over a clearly identified model. If you want a known model with a restoration statement, the E2 and SRX listings below are more specific.

  • Crevice tool, upholstery brush, floor brush

Best for
Wet and dry cleanup on a budget

Pros

  • Wet and dry capability
  • 2-speed suction control
  • Professionally restored and tested

Cons

  • Renewed, not new
  • Filter type listed as cloth

The Rainbow E2 Black Type 12 2 Speed Vacuum Canister System is an Amazon Renewed unit, described as professionally restored and tested. It has a 2-speed control for adjusting suction by surface and uses water filtration to capture dust and fine particles, according to the features.

The key difference from the other machines is its stated wet and dry capability, which the listing says handles liquid spills as well as dry debris. Knocked-over drinks near a gaming setup are exactly the kind of mess where that matters. Specs list 4 wheels, a corded power source and a maximum suction figure of 80 feet, which is an unusual unit for suction and is not explained.

The spec sheet lists the filter type as cloth, which conflicts with the water filtration described in the features and description. We would trust the description, but it is worth noting. The listing also does not state which accessories come with the unit, so the kit above is better if tools are a priority.

Best for
Genuine Rainbow basin fragrance

Pros

  • Made by Rexair
  • Eucalyptus scent
  • Works with Rainbow and RainMate

Cons

  • Pack size and use not detailed

The Rainbow and RainMate Eucalyptus Fragrance is the only genuine Rainbow add-on in this list, with Rexair named as the manufacturer and model number 79-0131-04. Its title calls it an air freshener for Rainbow and RainMate, and it comes as a pack.

That is nearly all the listing says. It gives package dimensions of 9 x 6 x 2 inches and a weight of 10.3 ounces but does not specify how many bottles are in the pack or how much to use. With water-filtration vacuums, fragrances are generally added to the water in the basin so the scent is released as air passes through.

Pick this if you want a first-party product for your Rainbow and like eucalyptus. If you prefer lemon or want a larger bottle, the two third-party concentrates below are alternatives.

Best for
Finer speed control on mixed floors

Pros

  • Four power levels
  • Water plus HEPA filtration listed
  • Suits stairs and upholstery

Cons

  • Refurbished
  • Listing says 2 speeds and 4 levels

The RAINBOW SRX Refurbished 4-Speed Canister Vacuum is described as professionally inspected and restored. It uses water filtration and offers four adjustable speed settings for carpets, hard floors, upholstery and other surfaces. The surface list includes stair steps, tile, hardwood and rugs.

The spec sheet adds details and a few contradictions. It lists 4 power levels but 2 speeds, and a filter type of HEPA and water, while the features only describe water filtration. Capacity is given as 4 pounds, and it runs on 120 volts. The listing mentions compatible accessories but does not specify which ones are included.

The SRX suits readers who want finer control across different surfaces, such as a low rug under the desk and a hardwood hallway. The E2 listing is the one to choose if wet pickup is essential, since the SRX listing does not mention it. To keep hard floors spotless between vacuum runs, our guide to a self-cleaning vacuum mop covers a different approach.

  • Four power levels
  • Water filtration, with HEPA listed in specs
  • Carpet, hard floor, stairs and upholstery
  • Corded, 120 volts

Best for
Lemon scent with biodegradable formula

Pros

  • Biodegradable per title
  • 12 fl oz concentrate
  • Spray or basin use

Cons

  • Third-party, by Kleenovate
  • Very little listing detail

The Odor Eliminator Air Freshener & Deodorizer Concentrate is made by Kleenovate, not Rainbow. Its title says it is compatible with Rainbow and other water-based vacuums, that it uses a biodegradable formula, and that it can be used for spraying as well as in vacuum basins. The bottle holds 12 fl oz, in a lemon scent.

The listing includes no description or feature bullets, only package dimensions of 5.55 x 2.64 x 2.6 inches and a weight of 14.07 ounces. The dilution ratio and ingredients are not specified, so follow the label once it arrives.

This suits someone who wants a lemon scent and values the biodegradable claim. If you want more product per bottle, the Fragrances Limited concentrate is larger.

The Rainbow, RainMate Compatible Deodorizer Concentrate is made by Fragrances Limited, not Rainbow. It is a 16 fl oz bottle in Lemon Fresh, the largest in this group, and the description says it is designed for water-filtration vacuums including Rainbow and RainMate.

The description explains use: add a small amount to the vacuum basin during cleaning to neutralize odors and add fragrance. It suggests everyday cleaning, pet areas, seasonal refreshes and getting the house ready for guests, such as before a watch party. It does not list ingredients or a biodegradable claim.

Choose this for the most concentrate per bottle. If you prefer a genuine Rainbow product, the eucalyptus fragrance above is the first-party option.

NOTES

Buying Tips for Rainbow Water-Filtration Vacuum Systems

With renewed and refurbished units, the listing wording is your main guide. Look for a clear model name, a statement on restoration and testing, and a list of included accessories. Where a listing is vague or contradicts itself, ask the seller before ordering. Water filtration works best when the basin is emptied and rinsed after each use, since standing dirty water can smell, which is also why deodorizers exist.

For fragrances, a small amount goes into the basin water. Genuine Rainbow fragrances come from Rexair, while third-party concentrates are made for Rainbow systems by other companies. Follow each label for dosing. If you like to keep cleaning supplies low-waste, our look at laundry detergent refills follows the same idea.

FAQ

How does a Rainbow water-filtration vacuum work?

Air and dirt are pulled through a basin of water, which traps dust and debris instead of a bag. You empty the dirty water after each session.

Is the E2 Black Type 12 new?

No. It is an Amazon Renewed unit, described as professionally restored and tested.

Which Rainbow unit handles wet spills?

The E2 Black Type 12 listing states wet and dry capability. The other vacuum listings do not mention wet pickup.

Are the lemon deodorizers made by Rainbow?

No. They are third-party products from Kleenovate and Fragrances Limited, made to work with Rainbow systems. The eucalyptus fragrance is made by Rexair.

How many speeds does the SRX have?

The title and features describe four speeds, and the spec sheet lists 4 power levels but also 2 speeds, so the listing is inconsistent.
