Kalorik Vacuum vs. Rainbow: Which Water Filtration Vacuum Cleaner Should You Choose?

Kalorik Vacuum vs. Rainbow, Which Is Better?

Filtration vacuum cleaners like Kalorik and Rainbow succeed, whereas traditional vacuum cleaners struggle to pass the testing stage. This is because they don’t rely on dust bags to collect water; instead, they force the vacuumed air into a water reservoir. The water reservoir then keeps the dirt trapped in the water, preventing it from returning to the atmosphere. Both Kalorik and Rainbow vacuums are excellent for allergy sufferers looking for a hypoallergenic vacuum cleaner to eliminate dust mites and allergens.

This article is aimed at comparing Kalorik and Rainbow vacuum cleaners and helps you make an informed decision when choosing. On the one hand, the Kalorik vacuum cleaner is considered one of the best water filtration vacuum cleaners. However, most people avoid this brand because Kalorik vacuum cleaners tend to be very expensive, although there are affordable options. On the other hand, the Kalorik vacuum cleaner works well on different surfaces, whether soft or hard, and the wheels make maneuvering easy.

Meanwhile, the Rainbow vacuum is a high-quality water filtration cleaner that uses water to remove dirt and allergens. It can clean different surfaces and has other models, from high-end to low-end options, like the Kalorik vacuum. Both Kalorik and Rainbow vacuums undoubtedly offer impressive power, reach, and functionality to clean your home, making it allergen-free.

Meanwhile, the Rainbow vacuum cleaner has a fitted dolly that makes maneuvering its heavy weight around the house easy. Blue LED lights are fitted to the water bowl to provide an aesthetic appeal, and the transparency lets you see it at work.

Rainbow vacuums come in a jet black color scheme with a rainbow design at the front.

The detachment action parts of the Rainbow vacuum are colored gray to help you differentiate them. There is an allowance at the back of the vacuum cleaner where you can store the long cord easily. A rubber bumper on the vacuum’s sides protects it and whatever objects are on their way from scratches.

Kalorik Vacuum vs. Rainbow: Cleaning Power

Rainbow Vacuum Review


The Rainbow Vacuum features a unique dual filtration system that makes it user-friendly and safe for asthmatic patients and people with allergens. The dual filtration system comprises a water-based filter and True H13 HEPA filter media. The water in the filter is designated for dissolving pollutants and allergens while absorbing most of the particulate dirt. In addition, the water-based filter protects the accompanying HEPA filters from getting clogged; only stubborn microscopic dirt gets to it.

The dual filtration system of the vacuum cleaner is one of the reasons it is expensive and durable. The vacuum can use the expensive HEPA for a long time without needing to replace them. The vacuum cleaner also has a powerful suction designed to deliver intense power while keeping energy efficient. So while it removes dirt from your carpets and floors, it helps you save money on energy bills.

The vacuum cleaner can also double as an air purifier; simply set it in the middle of a room. In addition, the Rainbow vacuum cleaner can release fragrances, featuring specialized attachments that help it work more efficiently. For example, the RainbowMate is designed to increase the cleaner’s reach, while the AquaMate lets you shampoo your floors and carpets. Additionally, the MiniJet is designed to be used on smaller vacuuming tasks that require shampooing.

Kalorik Vacuum vs. Rainbow: Which Should You Choose?

Both Kalorik and Rainbow vacuums are great options, but they don’t offer the same values. If you want more features in your vacuum cleaner, you’ll want to go for the Rainbow vacuum. However, be ready to pay more because those extra features come with an additional cost. The good news is that the vacuum cleaner is high-quality and built to last very long.

That means once you buy the Rainbow vacuum cleaner, you’re set for at least a decade – or until you’re tired. Meanwhile, the Kalorik vacuum is equally a great option if you want a “cheaper” vacuum cleaner. We say “cheaper” because it is less expensive than Rainbow, but many people shy away from Kalorik vacuums because they are also costly. Still, it is excellent for removing hair, dust, and debris from carpets, crevices, furniture, and hard-to-reach areas.

When choosing between Kalorik and Rainbow vacuums, you want to consider your budget and how many features you need. Also, consider the level of convenience you desire; both vacuums offer convenience, but Rainbow offers more, howbeit at a cost. Also, consider their suction power; the Rainbow Vacuum costs more, so naturally, it has a more powerful suction. However, don’t let the lower price on Kalorik fool you; its suction power is pretty impressive, giving you a run for your money.
