There is interest in developing powerful battery packs that could potentially allow vacuums to operate without being tethered to an outlet, similar to backpack leaf blowers. While central vacuum systems are effective in smaller spaces, the discussion highlights the need for portable solutions in larger areas. Concerns about safety and practicality of strapping heavy battery packs to a person's back were raised, alongside the feasibility of using existing battery technologies. Some users noted that backpack vacuums already exist and can be powered by lithium batteries. Overall, the conversation reflects a desire for more efficient and flexible vacuuming solutions.
