What Is the NIULI S21 Electric Sweeper?

The S21 Electric Sweeper is a battery-driven, ride-on industrial floor cleaning machine manufactured by NIULI. It integrates both sweeping and scrubbing functions, allowing operators to remove dust and stains from hard floor surfaces simultaneously — completing full ground cleaning in a single pass.

The machine features a fully enclosed cabin that blocks dust exposure for the operator, making it well-suited for environments where air quality and operator comfort are priorities. Its low-noise operation makes it appropriate for use in occupied commercial and industrial spaces.
