Upright vacuums are the oldest type of vacuum but they're still well worth considering. Though they're much heavier and clumsier than modern cordless vacuums, they're much more powerful, because they can house larger motors. Because they're larger, they can also vacuum up more dirt in one go than most cordless vacuums, saving you from having to empty the dust canister every time you use the vacuum. What's more, because they're so old-school, they tend to be cheaper than new-fangled cordless vacuums.
