The present invention relates to a residential-sized waste disposal roll-out cart that includes a latch that automatically latches a lid in the fully opened position with the lid in close proximity to the side of the bin. When the bin is tilted on to the wheels to be rolled, the lid remains in close proximity to the side of the bin, rather than hanging down towards the ground. In this way, the lid remains out of the space where a user might step. A lid reinforcement structure may be used to increase the strength and wear of the lid where it engages the latch.
