This company is trying to sell you a very expensive vacuum cleaner.  In a few weeks somebody will come to your door offering to clean the carpet in one room. Then they show you how theri machine cleans even your cleanest carpets. Sometimes they ask the same questions in person, that's how I found who they are. They are using the survey as a way around the do not call list. If they identified themselves as a company selling vacuum cleaners they could receive heavy fines.

Caller asked about 10 questions - about pets, air filters, kids, marital status and vacuum cleaners. Last question was "Have you used a credit card in the last 3 years?" After I hung up, it felt kind of questionable - why would they ask that? Did I just agree to something unknown?
