Key Differences That Matter
Larger Tank Capacity = More Cleaning Between Refills
The ONYX DX20 features a 14-gallon solution tank and 16-gallon recovery tank, giving operators more cleaning time before stopping to refill or empty tanks. Many competing models in this category offer solution tanks closer to 11 gallons, resulting in more frequent interruptions during larger cleaning jobs.
Standard AGM Batteries = Lower Maintenance
Unlike most competitors, the ONYX DX20 comes standard with maintenance-free AGM batteries. This eliminates battery watering, reduces routine maintenance, and provides a consistent machine specification across every unit.
Most competing manufacturers offer AGM batteries only as an optional upgrade, adding cost while creating variations in machine configuration.
Balanced Runtime for Daily Productivity
With an estimated 3–4 hour runtime, the ONYX DX20 is well suited for the cleaning requirements of schools, healthcare facilities, retail stores, offices, and other commercial environments.
Its runtime supports extended cleaning sessions with fewer charging interruptions, helping operators maintain productivity throughout the shift. Variable pad pressure for wider application versatility and battery life optimization between charges.
Simple Pad Assist Operation
The DX20 uses a proven pad assist drive system that combines reliable cleaning performance with straightforward operation. With fewer moving components than traction-driven machines, it offers reduced mechanical complexity, easy operator training, and dependable day-to-day performance.
For facilities looking for a durable, high-specification scrubber at an affordable price, the DX20 is an excellent choice.
