This is not my first Shark vac, and I also have a Ninja coffee maker.  Both are wonderful products and last for a very long time.  Your costumer service is amazing.  But after 5 or more years it was time for a new vac and this one has exceeded my expectations.  I've had my new Shark for almost a month and vacuuming is a joy!  I didn't realize how much I needed a new vac until this one arrived.  All the features are easy to use and really have sped up my cleaning process.  My only complaint is that the cord is not log enough to complete my entire first floor like my last Shark vac.
