Oreck’s Cordless Vacuum with POD Technology has a self-sealing and disposable container that locks in dust and debris, so it doesn’t escape into the air when you remove it from the cordless vacuum. Instead of emptying the pod into the trash can, you drop the whole thing in and replace it with a fresh one for your next vacuuming. Oreck sells a pack of five refill PODS for $15. Unlike a conventional vacuum, this Oreck is light in weight and easy to push around and maneuver. Its low-profile head slips easily between chair legs and under couches and cabinets. Using it overhead to grab cobwebs and to clean curtain tops won’t strain your back either.
