The NSS Charger 2022 DB 20-Inch Walk-Behind Auto Burnisher OBC, 220AGM 6402028 combines the proven Charger 2022 DB platform with a sealed AGM battery system and the convenience of an onboard charger.

Its 2200 RPM pad speed, 70 pounds of pad pressure, Vac-Trac dust control, and 20-inch working width make it well suited for high-speed maintenance of finished hard floors and compatible polished-concrete surfaces.

Onboard Charger

The defining feature of model 6402028 is its onboard charger.

Keeping the charger built into the machine can simplify charging because operators do not need to store, transport, or connect a separate external charger.

This is especially convenient in facilities where the burnisher moves between multiple storage or charging locations.

220AGM Battery System

This configuration uses a 220AGM battery system.

AGM batteries are sealed and require less routine maintenance than conventional flooded lead-acid batteries.

Benefits include:

• No routine battery watering

• Sealed construction

• Reduced maintenance requirements

• Clean cordless operation

2200 RPM Burnishing Speed

The Charger 2022 DB operates at approximately 2200 RPM.

This ultra-high-speed pad rotation is designed to quickly restore gloss and appearance to compatible finished hard floors.

70 lb. Pad Pressure

The machine applies approximately 70 pounds of pad pressure.

The combination of high speed and consistent floor pressure supports dependable burnishing performance.

Concrete Polishing Capability

NSS identifies the Charger 2022 DB as suitable for concrete polishing with compatible diamond pads.

This gives facilities additional flexibility beyond traditional finished-floor burnishing.

Vac-Trac Dust Control System

High-speed polishing can create fine floor-finish powder and dust.

The Charger 2022 DB incorporates NSS’ Vac-Trac Dust Control System into the pad-motor shroud to collect debris generated during operation.

This helps reduce loose dust left behind after burnishing or polishing.

Clean Battery-Electric Operation

Battery-electric operation eliminates the need for:

• Propane fuel

• Fuel-cylinder handling

• Engine oil changes

• Combustion-engine maintenance

• Indoor combustion exhaust during operation

This makes the Charger 2022 DB a practical alternative to propane burnishers in many indoor facilities.

68 dB(A) Sound Level

The machine operates at approximately 68 dB(A).

Its relatively quiet electric operation can be useful in facilities where floor maintenance may take place during occupied hours.

Walk-Behind Maneuverability

The 20-inch walk-behind platform provides a strong balance of productivity and maneuverability.

It is well suited for:

• Hallways

• Retail aisles

• Classrooms

• Patient-care areas

• Offices

• Large open commercial spaces

Professional Applications

The NSS Charger 2022 DB is well suited for:

• Schools and universities

• Hospitals and healthcare facilities

• Retail stores

• Grocery stores

• Office buildings

• Warehouses

• Government facilities

• Hospitality environments
