Hoses - Crushproof & Wire Reinforced
A central vacuum hose, more than any other component, impacts the overall performance of your central vacuum. The reason for this is friction which occurs inside the length of hose. Crushproof style hoses suffer considerably less performance loss than their wire reinforced counterparts, this is because the interior of a crushproof hose is smooth thus resulting in less turbulence. Therefore choosing a hose which is crushproof over a wire reinforced hose will give you better cleaning power right away. Basically there are two types of hose construction available, crushproof or wire reinforced. Most companies offer the crushproof style hose simply because it has superior benefits such as being light weight, offers better airflow and being that it is "crushproof", it springs back to shape after being stepped on or crushed. Even the diameter of a hose results in performance gain or loss. Choosing a hose which has a diameter of 1-3/8" compared to 1-1/4" results in most cases a 20% improvement in airflow performance. When choosing a hose for your system, make sure that it turns the unit and the power nozzle "on" and "off". In addition, the hose you choose should also be equipped with a 360 degree swivel handle. This reduces hose tangle and wrist strain. Basically...

Crushproof Hoses Are Better.
