I love my kenmore. I had one for over 15 years and am now on my second one only due to the wheels finally breaking off to the point where it couldnt be fixed. I got them both at sears and bought the maintenance deal they have which cleans and changes the filters and bags for you once or twice a year. That alone is deal because the filters can be pricey. The first one I had was around $400 dollars but this time around I went for the $250 model and I have been just as happy. This one is smaller so it was easier for the stairs. Hope this helps.
