The S21 is designed for large-scale indoor cleaning applications. Common environments include:
Manufacturing Factories: Removes industrial dust, debris, and floor stains efficiently
Warehouses and Logistics Centers: Covers large floor areas quickly with a wide 2,050 mm cleaning path
Shopping Malls and Retail Spaces: Low-noise operation allows cleaning in occupied areas without disruption
Commercial and Public Facilities: Suitable for any large indoor space requiring regular, thorough floor maintenance
The S21 is best suited for operations that require frequent cleaning of large hard-floor surfaces, where a single pass must deliver both dust removal and floor scrubbing. Facilities managing smaller areas or outdoor surfaces may be better served by other models in the NIULI electric sweeper range.
Q: What is the maximum cleaning efficiency of the NIULI S21 electric sweeper?
A: The S21 achieves a maximum working efficiency of 14,350 square meters per hour, making it one of the most productive options for large indoor floor cleaning.
Q: Can the S21 sweep and scrub at the same time?
A: Yes. The S21 is an integrated sweeper-scrubber, meaning it removes dust and washes the floor simultaneously in a single pass — reducing cleaning time significantly compared to using separate machines.
Q: What battery options are available for the S21?
A: The S21 is available with either a lead-acid or lithium battery, both rated at 48V/100AH. Lithium batteries are better suited for operations requiring faster recharge cycles or longer service life, while lead-acid batteries offer a lower upfront cost.
Q: How long does the S21 run on a single charge?
A: The S21 provides 3 to 4 hours of working time per charge, depending on operating conditions and battery type.
Q: Does the S21 have a fully enclosed cabin?
A: Yes. The S21 features a fully enclosed cabin that isolates the operator from dust and provides a more comfortable working environment compared to open-cab sweepers.
Q: How many side brushes does the S21 have?
A: The S21 is equipped with four side brushes, each 500 mm in diameter, ensuring thorough cleaning along edges and in corners.
Q: What are the water tank and dustbin capacities?
A: The S21 has a 160-liter water tank and a 155-liter dustbin, allowing extended cleaning sessions without frequent stops to empty or refill.
