I give it one star only because there was nothing less than that.  I have used Electrolux vacuum cleaners for over thirty years.  I made a mistake when I let the lying snake of a salesman talk me into buying the "top of the line".  It takes very little to knock off the hepa filter, it's heavy and is very over rated.  I did not get my warranty and instruction book when my machine was delivered.  I only had the word of a lying salesman about the warranty on this machine.  I have had problems with it but there is no need to call customer service since they will almost call you a liar.  The company I am dealing with now is no where near the company I started dealing with in 1973.  I believe they will not be able capture the purchasing from younger generations.  They are in no way customer or consumer friendly.  Between the machines I have purchased and family members have purchased in the past few years, it amounts to about 20 machines.  None of these will be replaced by Aerus Electrolux and they really don't care.  They do not deserve to have a profitable business.    They are way over priced for what you get.  I wouldn't have minded the cost if I was dealt with fairly by the company.
