I hate to give a company a 3 score but the Electrolux products cost a lot and usually live forever. We bought a whole house system and had it installed in my daughter's new home as a gift. With a little help from a friend, the two of us installed this in about 8hrs (we are both very handy). They wanted a a large fee to install the system. The roller on the main vac broke in about 2 yrs and two of the handle attachments snapped off within another two years. I think this would be a better product if it was not made of plastic everywhere. A few more steel parts would toughen up the unit. Parts are reasonable to replace and this company will order them and mail them to you. Not many systems in stock to view ahead of time.
