In an upright vacuum, the motor, filter, any dust bags, and the power head are all part of one unit, which users push in front of themselves during cleaning. This all-in-one design means that uprights often feel much heavier, but with their weight tends to come additional power that deep cleans carpets. There is one downside to the greater power, however: uprights are also generally much noisier than canister vacuums. Even so, quieter designs are around if one looks for them.
