Onyx 24" Lithium-Ion Floor Burnisher – SXi-2402, Dual Battery

The Onyx SXi-2402 is built for high-performance, eco-friendly floor care with advanced technology and extended runtime. Its patented floating shroud and integrated dust collection system capture fine polymer dust at the source, removing the need for post-burnish dust mopping. A micro-filter vacuum bag traps particles as small as 0.5 microns, ensuring cleaner indoor air while meeting Green Seal GS-42 and LEED standards for sustainable cleaning.

Powered by two lithium iron phosphate batteries, this model provides up to 4 hours of continuous runtime per charge—allowing operators to cover larger spaces efficiently. With quiet operation, adjustable pad pressure, and an onboard monitoring system, the SXi-2402 makes it easy to achieve a brilliant floor finish while reducing both labor time and costs.
