The Miele C1 HomeCare is an excellent buy for the price.  It is the only sub $800 Miele canister that comes with a proper power nozzle.  This machine also comes with a barefloor/rug tool, dusting brush, crevice tool and upholstery tool. 
 
The advantage to buying a HomeCare by Miele are many.  You get two additional tools; the flexible crevice tool which is great for cleaning out dryer vets, under appliances and in the car. You also get a larger dust brush with two swiveling elbows. It works well for cleaning ceiling fans, air return vents, crown moldings, and blinds.  
 
The biggest advantage of getting a HomeCare is the extended warranty.  All HomeCare machines come with a 10 year warranty on the motor and housings and a 5 year parts and labor warranty on everything else!
