Sirena vs Rainbow Water Filtration Vacuum Comparison
1 in 9 Australians have asthma – around 2.7 million and many more with allergies. Asthma and allergy sufferers are constantly in discomfort caused by dust and pet hair and are now looking to water filtration vacuums to rid their homes of allergens. Let's compare the Sirena Vacuum Cleaner to the Rainbow and see which is the best.
Why Choose A Water Filtration Vacuum?
Water filtration systems like the Sirena Vacuum Cleaner and Rainbow Vacuum Cleaner succeed where traditional vacuum cleansers fail.
Instead of relying on dust bags to collect dirt, water filtration vacuums force the vacuumed air into a water reservoir, which keeps the dirt trapped within the water and thus prevents it from being blown back into the air.
This is of critical importance for allergy sufferers who are looking for a hypoallergenic vacuum that can eradicate dust mites and allergens from the home, instead of sucking it in and blowing it back out.
This blog aims to compare the two popular models of bagless water filtration vacuums on the market: the Sirena vs Rainbow E2 Black Model.
Let’s take a closer look at the two water-based vacuum cleaners.
The Sirena vs Rainbow E2 Black
The Sirena Vacuum Cleaner is a Canadian designed and engineered total home cleaning system.
It uses water-based filtration technology that won’t clog as you vacuum. This means you’ll have 100% uncompromised airflow ensuring a deep and thorough clean. The power of this system will allow you to clean your entire home without the need for nasty chemicals. This includes hard surfaces, carpets, rugs and upholstery.
The Sirena system also comes with multiple attachment heads and nozzles designed to clean different surfaces in your home.
Both the Sirena and the Rainbow utilize HEPA filtration to purify the air.
The Rainbow E2 is also a high quality water filtration vacuum that relies on the power of water to remove allergens and dirt.
The Rainbow is able to clean a variety of surfaces, just like the Sirena. However, the E2 Black Model comes with simplified attachments compared to it’s predecessors. This newer model no longer comes with the curved wand, which is unfortunate as it can be extremely useful for cleaning hard to reach nooks.
Another key difference between the new Rainbow vs the Sirena Vacuum Cleaner is that the E2 Black Model now has just one hose for ‘wet & dry’. The Sirena and the previous ‘E Series’ Rainbow models have two hoses: one for wet and one for dry.

Advantages of Buying the Sirena Over the Rainbow E2 Black Model
- The Sirena Vacuum Cleaner is 2-3 times less expensive than the Rainbow: you may be able to find either on discount or perhaps as a second hand unit. But at regular retail price, the Rainbow E2 Black Model is 3 times more expensive than the Sirena
- The Sirena comes with a much larger water reservoir: the water reservoir of the Sirena is almost double the size of the Rainbow. Rainbow offers a larger water reservoir as an additional purchase, but you will need to fork out more money for the upgrade
- The Sirena has a longer warranty: both machines will last you a long time However, the Sirena offers a 10-year motor warranty compared to 8 years for the Rainbow
- The Sirena comes with a curved wand: the Rainbow does not
Comparing the two vacuums, we can see that they are fairly similar in terms of power, reach and functionality. Both machines perform well and can transform your home into a truly clean and allergen-free environment.
So can we justify the additional expense involved in purchasing a Rainbow? We believe that the Sirena Vacuum Cleaner is a superior product and also costs a third of the price of the Rainbow E2 Black Model.
That’s incredible value to match the incredible performance.
Bagless water vacuums are the only way forward for a truly clean home, as they are able to not only remove dirt and allergens from surfaces but also keep it from being released back into the air. Traditional bagged vacuums simply don’t cut it for people who suffer from allergies, sinus difficulties, asthma or breathing conditions.
So if you’re serious about eliminating allergy triggers from your home, we recommend you give a water filtration vacuum cleaner some wholehearted consideration.
