The DC520 is suitable for medium commercial and industrial facilities that need a walk-behind scrubber with large water tanks. It has a 510mm cleaning width and a rated efficiency of up to 1,800m²/h. Potential applications include supermarkets, hospitals, schools, workshops, warehouses, parking areas and transportation facilities.

The theoretical coverage is approximately 5,400–9,000m² per charge. This estimate is calculated from the rated efficiency of 1,800m²/h and the specified working time of 3–5 hours. Actual coverage will be lower because of turning, overlapping, water servicing, floor condition and operator speed.

The 620mm-wide machine body is relatively compact, but the 850mm rear squeegee determines the operating clearance. The complete machine measures 1,400 × 620 × 1,050mm. Buyers should measure doors, elevators, aisles and storage entrances and confirm whether the squeegee can be folded or removed during transportation.

The DC520 combines a 480W brush motor with 35kg of scrubbing pressure. This provides stronger mechanical cleaning action than light-duty compact machines. Actual results also depend on brush or pad selection, chemical dilution, floor material, contact time and operator speed.

The DC520 uses an 850mm squeegee and a 550W suction motor for wastewater recovery. The recovery path is 340mm wider than the 510mm scrubbing path, helping collect water during turns and normal operation. Drying performance also depends on blade condition, squeegee adjustment and floor flatness.

Yes, the 65L fresh-water tank and 65L wastewater tank are intended to reduce servicing interruptions. Actual refill and drainage frequency depends on water-flow settings, soil level, cleaning speed and route layout. Buyers should compare the capacity with the planned shift and distance to the service area.

The confirmed specification is a 24V battery system with a stated working time of 3–5 hours. Battery capacity, chemistry and charging time are not included in the supplied parameter sheet. Confirm the amp-hour rating, lead-acid or lithium configuration, charger voltage, plug type and replacement-battery availability before ordering.

The supplied parameter sheet does not list a traction motor, so buyers should not assume that self-propelled drive is included. This is important because the machine weighs 150kg. Confirm whether the quoted configuration is manual-push or self-propelled and, if powered, request the traction-motor rating, speed range and forward/reverse functions.

The DC520 is intended for compatible hard floors when fitted with the correct brush or pad. Confirm suitability for tile, sealed concrete, terrazzo, vinyl, epoxy or stone surfaces. Sensitive, polished and coated floors should be tested in a small area using the recommended pad, brush and cleaning chemical.

Confirm the propulsion, battery, charger, consumable, packaging and after-sales configuration in writing. The purchase specification should include manual or powered traction, battery capacity and chemistry, charger voltage and plug, supplied brush or pad, spare squeegee blades, warranty terms, packed dimensions, gross weight and replacement-parts availability.
