An onboard treatment solution injection system ( 40 ) includes a container ( 42 ) removably received in a holder ( 51 ) having a plurality of condition sensors ( 52 ) arranged in a vertical linear series. An injection pump ( 44 ) draws treatment solution from the container ( 42 ) and injects it into cleaning solution flowing in a line ( 15 ) from a solution tank ( 16 ) under action of a solution pump ( 18 ). The relative pumping rates of the pumps ( 18, 44 ) are controlled by a controller ( 58 ) controlled by the condition sensors ( 52 ) detecting a magnet ( 56 ) which is adjustably slideably mounted on the container ( 42 ) according to the type of treatment solution held therein. A valve ( 50 ) allows the injection pump ( 44 ) to be alternately in fluid communication with the container ( 42 ) or the solution tank ( 16 ) for purging.
