What Size Floor Machine is Best for Me?

While both 17-inch and 20-inch floor machines are used for resurfacing, the 17-inch floor machine is generally preferred by professionals for high-performance, heavy-duty resurfacing work, whereas the 20-inch machine is considered the standard for general, large-area commercial cleaning.

Here is a breakdown of why, based on common industry usage:

17-Inch Machine (Preferred for Resurfacing/Refinishing)

Better Down Pressure: For stripping, sanding, or grinding (resurfacing), a 17-inch machine often provides better, more focused downward pressure on a 1.5 HP motor, leading to more aggressive cutting power.

Maneuverability: It is easier to control, especially when working in tighter spaces or moving between rooms.

Versatility: Many professionals prefer a 17-inch deck because it can still easily drive a 19-inch or 20-inch pad, allowing for decent coverage while maintaining the ability to get into corners.

20-Inch Machine (Preferred for High-Productivity Maintenance)

Efficiency: The 20-inch machine covers more surface area in each pass, making it faster for large, open spaces.

Standard Size: It is considered the most common size for day-to-day commercial cleaning, scrubbing, and buffing.

Downside for Resurfacing:

In some cases, a 20-inch machine may not apply enough pressure to the floor as effectively as a 17-inch machine for heavy stripping or sanding jobs.

Summary of Considerations

  • Resurfacing/Stripping: 17-inch is usually better (more aggressive, better control).
  • General Cleaning/Polishing: 20-inch is usually better (faster coverage).
  • Hardwood/Small Areas: 17-inch is the standard.

For maximum productivity on large, open, flat areas (like warehouse concrete), a 20-inch machine is excellent, but for standard, everyday contracting work that includes tight spots and heavy, detailed grinding or sanding, the 17-inch machine is often preferred.
