The Rexair Rainbow is neither a complete swindle nor an undisputed miracle. Its core engineering works as advertised: the water separation chamber and HEPA exhaust capture dirt with zero loss of suction, and the motor platform outlasts nearly everything sold in retail department stores. Yet the price tag includes thousands of dollars in direct-sales commission overhead that does not translate directly to raw performance advantages over elite, high-end bagged canister vacuums.
If you have disposable income, suffer from acute indoor airborne allergies, and don't mind the mandatory chore of cleaning your vacuum cleaner after every run, the SRX delivers an exceptionally clean home. For everyone else, carrying heavy basins of dirty water to the toilet will quickly wear thin, leaving a several-thousand-dollar machine sitting idle in the back of the closet.
