There is no definitive answer to this question as it depends on the specific make and model of hose. In the vacuum hose world, there are two types of suction hose: straight and curved. Straight suction hoses offer less suction power than curved ones that provide a more flexible path for air to flow through (for example in vacuuming tight spaces such as under beds or behind furniture). On the other hand, larger diameter design will require longer length of vacuum hose thus they take up more room while being able to produce greater air pressure.
