Works with any truck mount or portable machines (200 - 2000psi). Concentrates all the water pressure through an amazing new spray jet that creates extreme force for cleaning severely soiled grout. May be needed for some grout lines with extreme soiling. A must have tool for anyone starting hard surface cleaning as you can build up additional tools like the corner/edging tool and the 14” brush or squeegee heads. Please note that this does not come with any heads - the wand is ready to attach any of the Gekko range of heads.
