The DC50B is suitable for medium and large commercial or industrial facilities that need a walk-behind scrubber with larger water tanks. It has a 510mm cleaning width and a rated efficiency of up to 3,750m²/h. Potential applications include supermarkets, hospitals, schools, workshops, warehouses, parking areas and transportation facilities.

The theoretical maximum coverage is approximately 15,000–22,500m² per charge. This figure is calculated from the rated efficiency of up to 3,750m²/h and the specified working time of 4–6 hours. Actual coverage will normally 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 minimum 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 for transportation.

The DC50B combines a 480W brush motor with 35kg of scrubbing pressure. This provides a stronger mechanical cleaning action than light-duty compact machines. Actual results still depend on brush or pad selection, chemical dilution, floor material, contact time and operator speed.

The DC50B 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 tank 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 4–6 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.

A self-propelled configuration is referenced as an option, so buyers should confirm whether it is included in the quoted model. This is important because the machine weighs 160kg. The purchase specification should clearly state whether traction drive is included, its speed range, gradient limit and whether forward and reverse drive are provided.

The DC50B 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 traction drive, 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.
