Comparing Key Specs Side by Side
Cleaning Width
The SUNMAX 17-Inch Corded Floor Scrubber offers a wider cleaning path at 17 inches. This broader brush width covers more floor area with each pass. The SUNMAX 14-Inch Compact Floor Scrubber has a 14-inch cleaning width. The wider model is better for large, open spaces where speed matters. The narrower unit suits tighter aisles or smaller rooms. You should choose based on the width of your primary cleaning zones. Wider is generally faster for big areas.
Tank Capacity
Tank sizes differ significantly between these two machines. The 17-inch model features a dual tank system with a 7.9-gallon solution tank and a 9.2-gallon recovery tank. This allows for extended cleaning sessions without frequent refills or emptying. The 14-inch compact model has a single 4-gallon tank capacity. The larger tanks on the corded unit reduce downtime for refilling. If you are cleaning large commercial spaces, the bigger tanks are more practical.
Power Source
Power delivery is a major difference. The SUNMAX 17-Inch Corded Floor Scrubber runs on 110V plug-in power with a 26-foot cable. This provides continuous performance without battery limitations. The 14-inch model uses a 24V/52Ah maintenance-free lithium battery. It offers up to 2.5 hours of cordless operation. Battery power allows for movement without a cord, while corded power ensures unlimited runtime. Choose cordless for flexibility or corded for non-stop work.
Cleaning Productivity
Cleaning speed varies by model. The SUNMAX 17-Inch Corded Floor Scrubber achieves up to 19,000 square feet per hour. The SUNMAX 14-Inch Compact Floor Scrubber cleans up to 14,500 square feet per hour. The higher productivity of the 17-inch unit makes it faster for large areas. The 14-inch model is still efficient for its size. You should consider your total square footage. Faster coverage reduces the time needed for daily cleaning tasks.
Display and Monitoring
The SUNMAX 14-Inch Compact Floor Scrubber includes an LCD display. This screen shows operating time, error codes, and real-time status for brushes, vacuum, water, and battery. The data for the 17-inch model does not mention a display. The LCD on the 14-inch unit helps you monitor functions and identify alerts quickly. This feature aids in managing daily cleaning tasks and maintenance. If you want real-time feedback, this display is a clear advantage.
