Sirena Vacuum Cleaner - Water vacuum technology

Hose attachments

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)!


Brush attachments

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.

HEPA filter

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.


Easy maneuverability

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.

Additional tools

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.

Micro-Silver Technology

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.

This internal tank breaks down dust and dirt particles. By becoming absorbed into the water filtration system, the suction nozzle will not lose suction, and you won’t have to deal with clogged filters. In addition, quantum vacuum cleaners promise to do a better job than HEPA filters through their unique Micro-Silver filtering technology.


Adjustable attachments

Another aspect of the Quantum vacuum cleaner is its abundance of adjustable attachments that make cleaning up easier and more effective for specific floor surfaces. For example, for tight spots, the crevice tool can reach into those narrow corners of your home, and for dust you can attach the dusting brush.

It also has a telescoping body that allows you to adjust the length of the vacuum cleaner nozzle by extending or retracting it for greater versatility.

Water filtration system

One of the main reasons people seek out cleaning tools like the Quantum vacuum cleaner is its ability to clean wet spills. It does this through a sophisticated water filtration system.

Quantum can promote consistent suction power as dust and dirt go into the attached water tank component. This is rather than using dust bags that could clog up the suction power of the vacuum nozzle. This water filter system enables the Quantum vacuum cleaner to pick up anything from children’s spilt milk to pet hair from your dog.

This incredibly large and powerful brush also makes it easy to achieve deep cleaning results with thick carpets and hardwood floors.

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.

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.

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.
