An upright vacuum boasts convenience, mobility and power, all in a vertical frame.
Upright vacuums naturally stand vertically, and are kept that way, with the control handle at the top. There’s no bending over or dragging something behind you and around the room (like a canister vacuum). It’s all under your immediate control. Uprights can do entire rooms very quickly, as all you are doing is easily moving, guiding, “driving” a portable unit – always right in front of you — around chairs, along baseboards, and across large expanses.
Of course there are attachments available with some uprights such as a hose to get into difficult spaces, etc.
If you want convenience, portability, and power, an upright would not be a letdown!
