The selling point on Orecks is their weight which is only 8 lbs and are very easy to use and vacuum with. However, an Oreck actually weighs about 12 lbs. They only weight 8 lbs without the power cord, but of course you need the power cord to vacuum with. Parts are readily available and for a vacuum priced under $400 new, they actually last a long time. If I were to guess on an Oreck vacuum's average life span if properly taken care of, I would say 10 to 12 years. The strength of an Oreck vacuum is in its brushroll. Its brushroll speed is faster than your average vacuum, and so it is a really good sweeper and a decent vacuum. When using one, it appears to vacuum up everything in its path. That is really nice because it is nice to have a vacuum that works that well which is that light. A lot of elderly people use Oreck vacuums. Also a lot of people who have lots of stairs (a lot of people carry them around) use them as well.
