Water filtration vacuum cleaners are the future of vacuuming, offering many benefits from reduced allergen particles to perfect suction power. This article explores the many Rainbow vacuum alternative options to get comparably fantastic results at a fraction of the price!
Among the highest tier of such vacuum cleaners is the Rainbow System vacuum, which offers premium material quality at an exclusively high price.
Sirena Vacuum Cleaner
- Water and HEPA filter
- Motorized power nozzle
- Electric hose
- Wet and dry hose
- Telescopic wand
- Inflation tool
- Floor brush
- Small cleaning brush rollers
- Custom suction speeds
- Power: 1200 W

- Weight: 40.2 lbs

The Sirena vacuum cleaner comes with various hose attachments, including a premium electric hose and a premium hose for wet and dry messes. Both hoses come in at 6 feet in length and offer high cleaning potential from vacuuming carpets to tiles and even wooden floors.
They can also suck dirt particles in the form of solids and liquids. So, whether you’ve spilled juice or knocked over some M&Ms on the floor, the Sirena vacuum cleaner can clean it all up (1)!
Beyond cleaning up floor surfaces, the Sirena vacuum cleaner is also ideal for cleaning fabrics such as sofas, curtains, and lampshades. This is because of the many brush attachment features included in the package, designed to tackle various cleaning tasks.
Such brushes include a dusting brush, a floor brush, and an upholstery tool made using horse hair bristles for easy removal and effortless replacement.
The washable HEPA filter separates the Sirena vacuum cleaner from a regular vacuum. This traps materials that are not water-soluble. That is materials that cannot be dissolved in water. This means that rather than overflowing dust bags with all the dust collected from surfaces and the air, they are mixed into the water basin, where they can easily be disposed of.
HEPA filters promote seamless suction power that never diminishes. In addition, it can act as an air purifier by collecting dust and dirt particles in the air, essentially making your home a more pleasant and hygienic environment.
A vacuum cleaner is only as good as it is easy to use. An ergonomic and maneuverable solution is key to your water filtration vacuum cleaner’s success. All four wheels have 360 degrees of functionality that allow you to glide across your home’s floor, whether tiled or carpeted.
The caddy can also be removed to keep your vacuum cleaner stationary for specific tasks, such as cleaning the staircase or reaching for a high area.
Sirena water filtration vacuums work with a range of additional tools and attachments that stretch beyond the realm of vacuuming alone. For example, a tool that allows you to inflate air mattresses, floatation devices, toys, and more by reversing the suction power into an outward-blowing mechanic instead.
It also has a telescopic wand to adjust the cleaning nozzle’s length. It’s a crevice tool that can assist in reaching difficult places like baseboards and between cushions.
- Huge range of attachments that clean effectively and efficiently.
- Additional tools and attachments such as inflation tool, crevice tool, and telescopic wand for convenience.
- HEPA filtration system helps to purify the air and promote flawless suction power.
- Brush attachments made of horse hair bristles provide easy maintenance and attract dust more effectively.
- 3 year warranty covers manufacturing defects or lack of quality in material.
- Quite bulky and heavyweight at 40.2 lbs.
- Limited color options.
Overall Sirena vacuum cleaner Review
Arguably the greatest competitor to the Rainbow System vacuum cleaner, Sirena offers one of the most premium water filtration vacuum cleaners at a lower price point. This canister vacuum uses 360-degree maneuverable wheels and a telescopic wand with a crevice tool attachment to ensure you can clean just about any area in the home.
Among its defining features is the HEPA filter, which means your Sirena vacuum cleaner does not just suck the dirt from your floor and furniture but also from the air itself. This promotes cleaner air quality in addition to a more spotless house!
While Sirena is by no means a budget water filtration vacuum cleaner, it does come at a cheaper average price than Rainbow vacuums. Therefore, I would recommend the Sirena vacuum cleaner as an alternative to the Rainbow System, which performs many of the same functions but at a lower price.

The Quantum X upright vacuum cleaner is notorious for its Micro-Silver technology. This filter effectively captures dirt, debris, pet hair, and more by neutralizing them and sucking them into the water basin.

- Capacity: 6.6 L
- Weight: 54 lbs
- Warranty: 5 years

The defining feature of the Bissell Big Green water filtration vacuum cleaner is its extra-large power brush that lifts a greater area of dirt, essentially making your job easier and less time-consuming. This incredibly large and powerful brush also makes it easy to achieve deep cleaning results with thick carpets and hardwood floors.
Unlike most water filtration vacuums that cap at about 1200 watts of power, the Bissell Big Green exerts an impressive 1400 watts for greater suction power and vigorous results.
Bulky, durable design
One of the perks of the Bissell Big Green vacuum cleaner is its bulky design that promotes durability and longevity. In addition, unlike regular vacuums, the Big Green is unlikely to get dented or cracked under pressure, so there is more leeway for accidents like dropping the vacuum down a staircase or accidentally stepping on it.
On that note, the bulky design makes this vacuum a little difficult, coming in at a heavy 54 pounds of weight to maneuver.
The Bissell Big Green differs from the other water filtration vacuums on this list by offering a 3-stage filtration process that ensures flawless suction power and dirt and dust elimination. Not only does this allow for deeper cleans of your carpet and hard floors, but also allows you to clean wet and dry messes while leaving the surface smelling fresh.
As such, the Big Green by Bissell works well for cleaning surfaces and vacuuming and collecting dirt, essentially making it a “mop and vacuum” hybrid of sorts.
- Durable and bulky design is made to last a lifetime of use.
- XL PowerBrush feature means more dirt is cleaned at an instance.
- Tough stain cleaning tools can tackle even the most resistant stains.
- Easy maneuverability across most home styles.

Overall Bissell Big Green Vacuum Cleaner Review
If you’re looking for a powerhouse vacuum that does the job without any of the “fancy stuff,” the Bissell Big Green is for you! This gigantic water filtration vacuum cleaner weighs a staggering 54 pounds. In addition, it comes with an extra large cleaning tool known as the XL PowerBrush, delivering a broader and deeper clean.
That’s not all that makes the Big Green “Big,” but also its incredibly large water tank capacity of 6.6 litres, giving you maximum cleaning time before changing the water is mandated.
Over 13,400 global Amazon customers have given the ever-popular Big Green a resounding 4.8-star rating, attesting to its incredible quality and exceptional results. In particular, customers love the extra large power brush, the huge water tank capacity, and the 3-stage filtration system that keeps all the dirt out of sight.
While priced at a lower point than the Rainbow vacuum, you will still need to put in some wallet work for this powerful beast of a vacuum cleaner, though it can prove to be a worthy investment for the long term.
Final Thoughts on Rainbow Vacuum Alternatives
All things considered, I would recommend the Prolux CTX as the best alternative to the Rainbow vacuum cleaner. For about half the price of its competitor, you get countless attachments and cleaning tools, a super lightweight design, and plenty of water tank capacity.
The suction power may not be the best, but its cheap price is certainly enough to deliver satisfying results with your home that you can be pleased with for the long run.
Of course, just about any water filtration vacuum cleaner on this list would make a good alternative to the Rainbow series, so keep your own needs and desires in mind when you purchase. For example, if you want more power and longer cleaning cycles, go with Bissell Big Green, but if you want lightweight flexibility and versatility in cleaning, go with Prolux CTX.
Regardless of which vacuum you choose from this list, you can be sure that you are receiving a cheaper alternative to Rainbow and a tool that performs just as well in keeping your home clean, tidy, and hygienic for a lifetime.
What is comparable to Rainbow vacuum?
There are many comparable alternatives to the Rainbow vacuum, such as Quantum, Ocean Blue, and Prolux, to name a few. Rainbow is a premium brand that is often priced out of reach for the everyday homeowner, so alternative products such as those listed here can bring relief for those seeking the water filtration vacuum experience without the big budget needed for Rainbow vacuums.
Is Sirena the same as Rainbow?
No, Sirena vacuum cleaners do possess many similarities to Rainbow, so they are considered a formidable competitor to the vacuum cleaning giant. However, Sirena is an entirely separate brand and has no affiliation with Rainbow in terms of business partnerships and connections, and both are high-quality water filtration vacuum brands.
What is so special about Rainbow vacuum?
Rainbow vacuum cleaners are special because they are one of the first to introduce the water filtration vacuum cleaning systems. These vacuum cleaners do an incredible job of eliminating dust particles and dirt from hard floors and carpets and promote greater suction power and purer air quality.
Does NASA use Rainbow vacuum?
It has been reported that NASA did in fact use the Rainbow vacuum cleaner before, though they do not sponsor the brand in any way. It should also be noted that NASA only used Rainbow to clean a facility in Cape Canaveral and did not use it to clean a space shuttle or rocket ship as may be falsely believed.
