Rainbow may make a better quality machine than Sirena, but the power nozzle designs have been flawed. I have not tested the latest Rainbow, so I cannot comment on that one. I do trust the carpet and rug institute tests. I’m not surprised that a Wesselwerks power nozzle would improve the performance of the amazing Rainbow. Canister vacuums are very versatile. I prefer a bypass upright even if it cannot perform as well as a Kirby. If rainbow has independent test results showing better performance than Kirby on carpeting then they should make them public.
