About

The story of the Rainbow® Cleaning System begins in the early 1930s, during a time when indoor air quality was rarely considered in home cleaning. It was then that Rexair, the company behind Rainbow, introduced a revolutionary idea: use water—not bags or dry filters—to trap dust and dirt. This simple yet powerful innovation would change the way people thought about cleaning.

In 1936, the first Rexair cleaner was introduced. Unlike conventional vacuums that relied on cloth bags and filters (which often allowed fine dust to escape), the Rexair used a water basin to trap particles. The principle was clear: wet dust can’t fly. This groundbreaking approach meant cleaner floors and cleaner air—something especially beneficial for allergy and asthma sufferers.

As the product evolved, so did the company’s vision. By the 1950s, the system was rebranded as the Rainbow, reflecting the idea of freshness, purity, and the natural power of water. The Rainbow system quickly gained popularity through its direct-to-consumer model, with trained distributors demonstrating the machine’s capabilities right in customers' homes.

Throughout the 1970s to 1990s, the Rainbow underwent several engineering upgrades. Improved motors, enhanced water filtration, and the introduction of the HEPA Neutralizer helped Rainbow meet growing consumer expectations for air quality and sanitation. The system’s ability to deep clean carpets, hard floors, upholstery, and even purify indoor air made it stand out as more than just a vacuum—it became a complete home cleaning solution.

Today, the Rainbow Cleaning System is sold in over 90 countries, and Rexair continues to manufacture the system in Cadillac, Michigan. The latest models feature state-of-the-art technology, including a powerful brushless motor, advanced airflow design, and a sleek, modern look—while still staying true to the original water-based filtration principle.
