Abstract: A cleaning liquid dispensing system for use in a mobile hard surface cleaner. The system generally includes a cleaning agent container, a cleaning agent supply line coupled to the cleaning agent container, a flow control device, and a pressure regulator. The cleaning agent container is configured to contain a supply of cleaning agent. The flow control device includes a first input coupled to the cleaning agent supply line, a second input, and an output. The pressure regulator is configured to control a pressure in the cleaning agent supply line and is positioned in line with the cleaning agent supply line between the first input of the flow control device and the cleaning agent container.

Abstract: A foamed cleaning liquid dispensing system includes a cleaner cartridge, a flow control device, and an aerator. The cleaner cartridge includes a collapsible bag containing a supply of cleaning agent. The flow control device is configured to receive a flow of the cleaning agent from the cartridge and a flow of a primary cleaning liquid component. The flow control device combines the flows of cleaning agent and primary cleaning liquid component and produces an output flow of cleaning liquid at an output. The aerator includes a nozzle having an inlet fluidically coupled to the output of the flow control device, an outlet, a body having a bore extending between the inlet and the outlet, and a radial port. The nozzle is configured to receive the output flow of cleaning liquid at the inlet, inject air into the output flow of cleaning liquid through the radial port, and produce an output flow of foamed cleaning liquid through the outlet.
