A Rainbow Vacuum Cleaner is a unique home cleaning system manufactured by Rexair LLC. It’s known for its water-based filtration system that traps dirt and odors, returning only clean, water-washed air to your home. It comes with a variety of attachments for versatile cleaning and is designed to significantly improve indoor air quality. Despite being more expensive and requiring regular maintenance, many users find its benefits outweigh its drawbacks.

Unique Filtration System

The Rainbow Vacuum Cleaner’s water-based filtration system sets it apart from traditional vacuum cleaners. Instead of using dust bags or filters to collect dirt and debris, the Rainbow Vacuum Cleaner forces the vacuumed air into a water reservoir. This process traps the dirt and odors in the water and prevents them from returning to the atmosphere. This water-based filtration system is particularly beneficial for allergy sufferers, as it effectively eliminates dust mites and allergens, which can be a common issue with traditional vacuum cleaners that allow small particles to escape back into the air.

Variety of Attachments

Another standout feature of the Rainbow Vacuum Cleaner is the variety of attachments that come with it. These include an upholstery tool, dusting brush, floor and wall brush, crevice tool, pet grooming tool, wet pickup/extractor head, attachment caddy, Aerofresh bag, inflator tool, 8-foot hose, and stainless steel wands. These attachments provide the power and versatility to clean your entire home, from floor to ceiling.

Improving Indoor Air Quality

It is certified by the Association of Home Appliance Manufacturers to remove pollutants from the air and is also certified as asthma and allergy-friendly. The vacuum’s wide assortment of cleaning attachments and optional accessories provide the power and versatility to clean various surfaces, including carpets, upholstery, hardwood, tile, and more.

Potential Drawbacks

Despite its many benefits, there are a few potential drawbacks to the Rainbow Vacuum Cleaner. Some users find the noise level to be too loud, and the vacuum’s weight and bulkiness can make it difficult to maneuver. Additionally, Rainbow Vacuum Cleaners are known to be quite expensive compared to other vacuum cleaners on the market. They also require constant maintenance, which can be time-consuming and frustrating for some users. Lastly, while the water filtration system is effective at trapping dust and allergens, some users find it inconvenient to empty and clean the water reservoir.

Customer Reviews and Ratings

Customer reviews and ratings for Rainbow Vacuum Cleaners are mixed. Some users praise their performance and effectiveness in trapping dust and allergens. Others appreciate the wide variety of attachments and cleaning capabilities. However, some users have reported issues with the vacuum cleaners, such as difficulty in emptying the water basin, problems with cord placement, and the high price.


In conclusion, the Rainbow Vacuum Cleaner is a unique and innovative home cleaning system that offers a variety of benefits, including a water-based filtration system, a wide variety of attachments, and the ability to improve indoor air quality significantly.
