Why the SXi is Redefining Floor Care


Burnishing machines powered by fossil fuels are unfavored by many facilities, and corded machines do not deliver good contractor productivity. Indoor air quality standards are increasing and green-certified equipment are facilities' go-to. The ONYX SXi solves these challenges by delivering:


  • Zero emissions
  • Exceptional power and runtime
  • Up to 240% more productivity than traditional corded models
  • Unmatched quiet operation for use in occupied or noise-sensitive environments


This lithium-ion powered system brings the strength of propane and the convenience of cordless—without the drawbacks. The SXi offers the performance professionals expect with the sustainability modern buildings demand.


Engineered for Versatility and Performance


The SXi offers performance, flexibility, and control that meet or exceed engine-powered machines. With a 3.75kW electric motor delivering the equivalent of 5 horsepower, the SXi provides:


  • 3x the power of a 20" corded high-speed burnisher
  • Variable speed control from 600 to 1,750 RPM
  • Straight-line operation at walking speed—no need to swing—Ergonomic superiority
  • Coverage of up to 34,000 sq ft per hour


It’s not just powerful—it’s precise. Operators can adjust head pressure in three ways to dial in results on VCT, terrazzo, polished concrete, and other hard floors.


Versatile Configurations for Demanding Environments​


Whether used in schools, healthcare facilities, big box retail, warehouses, or hospitality venues, the SXi delivers professional-grade performance while adapting to your workflow:


  • Configurable with 21", 24", or 27" burnishing heads
  • Single or dual lithium-ion battery setups (2+ or 4+ hour runtimes)
  • Quick-connect batteries for continuous operation
  • 10-gallon onboard water tank doubles as the battery cover—perfect for wet applications in SXi, TXi, or ZXi configurations
  • Low-profile LED light bar to illuminate the cleaning path


From daily maintenance to polishing decorative concrete, the SXi is built for all-day use across applications.


Quiet, Clean, and Cord-Free: The Future of Floor Care​


Running quieter than a household vacuum, the SXi can be used any time, anywhere without disturbing occupants. The SXi is ideal for hospitals, hotels, event venues, and other noise-sensitive locations.


According to ISSA, the SXi provides a 240% productivity increase over standard 20" corded burnishers, meaning less labor, fewer passes, and lower cost per square foot.


By eliminating fuel emissions, cords, and engine maintenance, the SXi also enhances jobsite safety while slashing operational costs. 

The Market Demands Sustainability—ONYX Delivers


The decorative concrete market is on the rise, expected to grow from $18.3 billion in 2023 to $24.3 billion by 2028 (CAGR 5.8%). As more architects, builders, and property owners opt for sustainable flooring, the demand for low-impact maintenance tools like the SXi will only grow.


Regions like California, where air quality regulations are among the strictest in the country, are driving this transition toward zero-emission equipment—and ONYX is leading the way.

Built on the Proven ONYX X-Series Platform
