There are some vacuum designs and features that, in the specific case of dirty, dusty stairs, can actually impede mobility and efficient debris extraction. The vac’s weight displacement is key. When traversing stairs with a suction system the last thing you want is a tipsy, dirt-filled upright or canister vac taking a tumble down the stairs. And while long and sturdy hoses are highly sought after in the traditional vacuum realm, the close-quartered stair-cleaning conditions don’t work well with these bulky and lengthy tunnels of whirling wind power. Power cords are a serious consideration when it comes to ascending to higher elevations while extracting disgusting debris. A lengthy cord can make a huge difference when it comes to navigating the narrow and sometimes winding passages of a staircase. However, a cord that’s too long can add a substantial amount of weight to the vacuum when not fully extended. Incorporating an extension cord into the mix may not be the worst thing, and can add some flexibility to the job, though it will require some added expenses and storage space.
