Yesterday I sat through a two hour demonstration of the "Rainbow Cleaning System" (from a friend of my son). I was quite embarrassed for this young man, and advised him to find another part time job as soon as possible. Are there really people out there gullible enough to buy this product? How do they justify the $2600 price tag (and that does not even include the power nozzle)? I'm an engineer and have a pretty good idea of what vacuum cleaner components should cost. Even manufactured in the USA, a conservative figure would be around $400. My recently purchased Kenmore with a HEPA filter costs $250. According to Consumers Reports, my model Kenmore received a high mark for carpet cleaning and emissions. The Rainbow also received a high mark for emissions, however it received a poor rating for cleaning carpet. Then there's the additional setup the Rainbow requires prior to usage and the cleanup required after usage. It just doesn't make any logical sense why someone would pay close to $3000 for a vacuum cleaner, when equivalent brands are available at a fraction of the cost.
When the young man requested referrals, I told him that I could not in good faith give him any based on the questionable claims he made about the product, and also that it bordered on being an outright scam.
