🎖️Quantum X Vacuum

Adarsh P/ Clean Homies

Quantum X vacuum cleaner has water filtration that helps suck the tiniest dust particles.

Not only that, but Quantum vacuums also suck germs, purify the air, and draw every harmful bacteria from the environment. The in-built water filter of the vacuum does not block the internals, thus preventing the dust from re-entering the environment due to circulation.

If pet hair is lying around, the vacuum cleaner must be emptied more often after using it. 

1️⃣Suction Power 

Quantum water filtration vacuum cleaner has superb suction power for deep cleaning. So instead of cleaning your carpet twice every week, you can get away with cleaning it once a week.  

With such a low sound, it is hard to believe how strong the suction power of this vacuum cleaner is.  

Also, you’ll notice a significant air quality difference once you start using the Quantum vacuum. It’s a brilliant pick for those suffering from dust allergies. It runs on 1200 watts.

2️⃣Deep Cleaning Strength

Each time you use Quantum X to vacuum your carpet, you will see less accumulation of dirt. 

When I first used the Quantum X vacuum cleaner, I had to replace the water in the canister quite a few times because my carpet was so dirty. But with regular usage, I can clean up to 1200 sq ft with just one or two water replacements. This means it has deeply cleansed my carpet over time.

The best part is this water filtration vacuum picks up dust and dirt without breaking the fibers of your carpet

3️⃣Ease of Use and Maintenance

Well, not to lie, I found Quantum X vacuum quite heavy. It weighs 27.1 lbs. But despite its weight, Quantum X is easily movable. 

Also, the heaviness adds to its sturdy construction, ensuring the vacuum cleaner is more long-lasting than others. 

The accessories that come with Quantum X are:

  • The separator cleaning brush
  • The dusting brush
  • The caddy
  • The upholstery brush
  • The water basin cleaning brush
  • The inflater tool
  • The crevice tool

Unlike typical vacuum cleaners, you don’t have to change clogged filters now and then. Plus, Quantum water filtration vacuums filter with normal tap water.

Oh, it is easy to clean under the furniture with a Quantum X upright vacuum! You don’t have to push it inside the corners to suck the dust from there. Keeping the water filter vacuum cleaner at a small distance will do a fair enough job. 

As Versatile As It Gets!

It works on all floor types with varying floor heights. In addition, it can vacuum both dry and wet carpets. I repeat, it can clean liquid messes or wet messes too! 

5️⃣Customer Support and Warranty 

Quantum X vacuum can be replaced or returned within 30 days if the user is dissatisfied with its performance. You get a refund of your total price! Plus, it comes with a 3-years warranty.

🏅Rainbow E2 Vacuum

Adarsh P/ Clean Homies

Rainbow Vacuum has the same water filtration technology as Quantum X Vacuum with certified air cleaning. 

It traps the dirt from the floors and carpets and puts them directly into the water compartment, leaving no scope for the dirt to re-enter your house via air circulation. Once done, you can easily dispose of the dirty water.  


In addition, Rainbow water filtration vacuums come with a 24-ft detachable power cord to easily clean any corner. 

1️⃣Suction Power

The suction power of Rainbow E2 is as good as Quantum X, so there’s no winner here. However, this vacuum works with 300 watts with great suction power, whereas Quantum X needs 1200. Meaning it’ll save you on your electricity bills.

Performance-wise, it is excellent at sucking all the dirt, dust, and debris with a noise louder than Quantum X. On top of this, I love how fresh and clean the air feels after vacuuming with Rainbow. 

2️⃣Deep Cleaning Strength 

Vacuuming twice a week is enough; you don’t have to repeat every alternate day. And trust me, that’s the first thing I look for because, yes, I’m lazy 😛

Everything gets trapped in the water, from the pet hair to dust, molds, debris, and bacteria, and you’re sorted for 3-4 days straight. 

3️⃣Ease of Use and Maintenance 

Yes, it’s heavier than Quantum X by some 3 lbs. However, three lbs don’t make much of a difference, provided the build and structure of the vacuum cleaner makes it convenient to carry. 

I will always appreciate the sturdy and durable build of Rainbow water filtration vacuums. They last long, even with daily use.

In case the vacuum has minor breaks, the repair is not very expensive. Moreover, you can easily find individual parts of Rainbow E2 in the market, as it has been around for a long time.

The additional attachments you can purchase separately for Rainbow machines are:

  • AquaMate (carpet cleaner add-on)
  • JetPad (extra wide hard floor mop tool)
  • RainMate (air humidifier add-on)
  • RainbowMate (for the mattress, carpeted stairways, and car interior cleaning), MiniJet (for upholstery cleaning) and 
  • RainbowMate IL for a sweet scent.

5️⃣Customer Support and Warranty 

Getting a 2-year warranty is a standard deal for water filtration vacuum cleaners. You can return the vacuum cleaner within 30 days of testing it with a full refund.

🏆Which Is Better: Quantum X Or Rainbow E2? 

From an investment point of view, the Quantum X water filter vacuum is a fairer purchase. It is a great budget water filtration vacuum.

Not only does the Quantum vacuum cleaner have great functionality, but it also comes with diverse features that other vacuums fail to provide. The accessories that come with the vacuum make a difference in your cleaning system. 

On the other hand, the Rainbow E2 water filter vacuum has easy maintenance features and wide customer support. The certified air purifier machine can last decades, even with daily use. 

Both the water filtration vacuums are far better than regular vacuums. So, you can go ahead and make the purchase based on your priorities.

  • After use, don’t try to pull the plug or use it as a handle while vacuuming. When you try to unplug it, instead of forcing the wires to be pulled, hold the back of the main unit or from the wall outlet to disconnect (after turning off the switch).

2 thoughts on “Quantum X Vacuum VS Rainbow: Which Is the Best Water Filtration Vacuum?”

  1. I appreciated reading this comparison!! I’ve been in love with the water filtration concept since the 90s, but I could never afford a Rainbow. Here’s my personal experience:
    I got the Quantum X in Sept 2021. I was over the moon at first. But this vacuum is SO heavy, I have 2 story house, and I could not carry it upstairs and downstairs UGH. It has no carry handle to use for lifting or distributing the weight. And my upstairs is all carpet, downstairs is hardwoods and tile. So I have to keep it only downstairs. The attachments with hose are not very good TBH. I was basically stuck with a vacuum I could only use on one level, meaning I needed 2 vacuums to get both stories. The water basin stains horribly from using the Quantum fragrances, so it looks awful and can’t be cleaned. Quantum customer service told me to buy a new one, but I’m seeing other Quantum users having the same issue. Quantum should replace it free since I followed directions and only used their fragrances.
    Quantum greatly disappointed me, so I got Sirena in September 2022. SUCH a huge difference! Plus, with the basin removed, I could carry the Sirena up and down the stairs much easier (Sirena’s handle on top made the huge difference!) The difference in versatility between Sirena and Quantum is unreal. I can literally clean everything in my house, top to bottom with Sirena. It’s definitely cumbersome and a lot of extra work to use though, so I’m not vacuuming as often as I should be. Sirena has AMAZING, unmatched suction, power, versatility and performance but I miss the convenience of an upright.
    Looking into the Shark Stratos upright now so I be sure I vacuum often. Stratos has upright convenience, but can be converted to a canister easily. Fully-sealed HEPA filtration too YAY! I’m always on the hunt for the “best of the best” vacuum LOL! Afyer spending $1,200 between the two, I have to now sell the Quantum AND Sirena so I can get the Stratos. Thought my personal feedback would be of interest to you. Thx for great reviews!
