Rainbow vacuum cleaners are considered by those that use them and vacuum experts to be the next generation in vacuum technology. This technology has been applied to help the average person maintain a clean living environment for themselves and their family. Independent tests have been conducted on rainbow vacuum cleaners and the results were that this vacuum cleaner traps 99.997% of all dirt that it picks up.

The history of this company started back in 1929 with the first patent on the process to separate dust from air was filed by John Newcombe and Leslie Green. Together they formed a corporation and called it Rexair, which meant king of the air. In 1941 this corporation merged with Martin-Parry Corporation. In 1955 the vacuum cleaner was redesigned and given a new name, the Rainbow. This was such an improvement from other vacuum cleaners at that time because of the power the vacuum motor had that interest grew in this new cleaner. In 1959 the rights to this new cleaner were purchased by Sanders and Associates. The models did not change much for ten years until 1969 with the first vacuum cleaner by this company was produced that was capable of picking up water. From that point on water became an important part of this cleaning system.

Today this company has developed vacuum cleaners for the international market. This is done by making specific vacuum cleaners for specific parts of the world. With special height adjustors and the ability to water-wash the debris picked up, today's Rainbow Vacuum Cleaners are considers some of the best cleaning machines in the world.
