So I decided on getting the 15 amp version of the Mighty Mite and let me tell you, this thing is as BEAST! It punches well above it's weight and just keeps on performing. The bags aren't expensive and they keep the air clean as well. Kudos to Eureka for making an incredibly simple and robust vacuum. It has all the features I need to get things done around the house. You can be sure the 15 amp motor isn't being stressed whatsoever and therefore will last much longer than an 8 amp motor. Don't think twice, get this model and be happy.
