Abstract: A base tool caddy for janitorial cleaning supplies is disclosed. The tool caddy has an inner circular element which can be in the shape of a cylinder. This inner circular element fits around the base of a standard commercial trash barrel. The inner circular element has an inwardly disposed lip that is designed to fit between the bottom of a commercial trash barrel and the top of the trash barrel's standard commercial wheeled dolly thereby securing the tool caddy to the trash barrel, dolly combination. The inner circular element has one or more outwardly disposed compartments designed to hold janitorial tools and supplies. These outwardly disposed compartments may be configured to serve as a bumper, thereby protecting walls and other surfaces from being marked by the trash barrel. The outwardly disposed compartments may incorporate a stabilizing edge to prevent the trash barrel from rolling when laid on its side.
