Make sure that all other models have good hose reach especially if there are tools onboard. This is usually preference. Both can work well. Most people prefer uprights. There are advantages and disadvantages to both types of cleaners.
Most uprights have tools on board or tools attachable.
Some uprights like Sharp, Sanyo, Panasonic, Riccar and Simplicity have by-pass motors . Rocks, coins, bolts and any hard object can not get into the motor fan system. This type always has more suction than vacuums where everything goes through the fan system. You won't have broken fans with this type of vacuum. By-pass motored units typically have more supplemental filters for cleaner exhausted air.
