The seven nozzles clean and washes away the debris on the floor at a constant distance and constant speed for the ULTIMATE PROFESSIONAL CLEAN.  Twin handle design for optimum manoeuvrability with twin heavy-duty castors for smooth consistent cleaning.  Will fit 3/8" (14.8mm) quick-release hoses. The roller casters keep the jets at the correct distance from the ground, making it easy to control and eliminate the risk of damaging patio grouting by holding the nozzle too close, which is easily done when just using the lance. Made from solid aluminium and stainless steel, a really durable piece of kit that is an alternative to the flat surface rotary cleaner.
