This system, known as "The Rainbow Opportunity", still remains to this date. Direct marketing of vacuum cleaners is often associated with unsolicited door-to-door sales. Rexair's independent distributors and their independent dealers use direct marketing techniques such as door to door lead generation, the use of referral gathering, and trade and home shows to get majority of their leads. Once a lead(name and contact information of prospect) is generated then the salespeople will attempt to contact this lead to schedule an appointment to show the Rainbow Vacuum Cleaner. A prospect is offered a gift for their time and no purchase of the Rainbow is necessary. Rexair teaches sales and marketing techniques through corporate distributor developers and through training seminars. The CEO Paul Vidovich and his staff also travel the world educating distributors on becoming more successful in the Rainbow business. Rexair manufactures sales promotional tools and sells them to their independent distributors. The main promotional tool they advocate is "Talent Scouting" which is recruiting another salesperson to join an organization. The recruiter can make money off the people they recruit similar to multi-level marketing strategies
During its 80 year history, Rexair has manufactured only nine models of the Rainbow.
