Some disadvantages of longer vacuum hoses include: limited maneuverability (the hose will not easily follow curvy pathways or paths that require twisting), and reduced accessibility when vacuuming in small spaces such as under cabinets or beds. These drawbacks are offset by the increased suction power of the hose. The length of vacuum hoses is also a factor in versatility and cost, so it's important to choose the hose size that fits your needs while considering other factors such as suction power requirements.
