The NSS Charger 2022 DB 6402026 combines a 20-inch, 2200 RPM battery burnisher with a 235AH battery system, 70 pounds of pad pressure, Vac-Trac dust control, and a sulky configuration for high-productivity commercial floor maintenance.

Features:

• Sulky Configuration – The key upgrade over the standard 6402024 configuration, adding the sulky setup for facilities seeking greater productivity over larger floor areas.

• 235AH Battery Configuration – Provides cordless commercial operation without managing a power cord during burnishing.

• 120V Charging Configuration – Designed for charging from compatible standard commercial electrical service.

• 20-Inch Burnishing Width – Provides a productive floor-care path while remaining maneuverable in commercial facilities.

• 2200 RPM Pad Speed – Delivers ultra-high-speed burnishing performance for restoring gloss to compatible floor finishes.

• 70 lb. Pad Pressure – Provides consistent floor contact for effective burnishing and polishing.

• Suitable for Concrete Polishing – Powerful motor performance makes the machine suitable for use with compatible diamond pads on polished concrete.

• Vac-Trac Dust Control System – Captures floor-finish powder and polishing dust at the pad-motor shroud.

• Integrated Dust Collection – Helps reduce loose dust left behind during high-speed floor maintenance.

• Battery-Powered Operation – Eliminates propane exhaust, fuel handling, and engine-related maintenance.

• 68 dB(A) Sound Level – Supports relatively quiet operation in commercial and institutional environments.

• Consistent High-Speed Performance – Combines high pad speed and controlled pressure to efficiently restore floor luster.

• Lower Routine Maintenance Requirements – Electric operation avoids propane fuel costs, oil changes, and many combustion-engine service requirements.

• Commercial Floor-Care Design – Well suited for schools, healthcare facilities, retail environments, warehouses, and other large finished-floor areas.

The NSS Charger 2022 DB 20-Inch Walk-Behind Auto Burnisher with Sulky 6402026 is designed for facilities that want the cleaning performance of the Charger 2022 DB platform with the added productivity of a sulky-equipped configuration.

It retains the core specifications of the standard Charger 2022 DB, including a 2200 RPM pad speed, 70 pounds of pad pressure, 235AH battery configuration, 120V charging, and Vac-Trac dust control.

Sulky Configuration

The primary difference between model 6402026 and the standard 6402024 configuration is the sulky setup.

This configuration is intended for applications where operators need to cover larger floor areas efficiently while using the Charger 2022 DB platform.

It can be especially useful in:

• Large retail facilities

• Warehouses

• Schools

• Hospitals

• Convention spaces

• Long corridors

• Other expansive finished-floor environments

235AH Battery System

Model 6402026 uses a 235AH battery configuration.

Battery power eliminates cord management during operation and allows the machine to move freely through large facilities.

Actual runtime will vary depending on:

• Battery condition

• Floor condition

• Pad type

• Burnishing load

• Operator technique

• Facility layout

120V Charging Configuration

The machine is configured for 120V charging.

This allows the battery system to be recharged using compatible standard commercial electrical service.

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 pad speed and consistent floor pressure helps produce dependable burnishing results.

Concrete Polishing Capability

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

This expands the machine beyond traditional floor-finish burnishing for facilities maintaining polished-concrete surfaces.

Vac-Trac Dust Control System

High-speed burnishing and polishing can generate fine powder and dust.

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

This helps maintain a cleaner surrounding environment and reduces loose dust after floor maintenance.

Clean Battery-Electric Operation

The Charger 2022 DB uses battery-electric power instead of propane.

This eliminates the need for:

• Propane fuel purchases

• Fuel-cylinder handling

• Engine oil changes

• Combustion-engine maintenance

• Indoor combustion exhaust during operation

The simpler electric drivetrain can also reduce routine maintenance requirements.

68 dB(A) Sound Level

The Charger 2022 DB operates at approximately 68 dB(A).

Its relatively quiet operation can make it practical for floor maintenance during daytime or occupied hours.

Professional Applications

The NSS Charger 2022 DB with Sulky is well suited for:

• Schools and universities

• Hospitals and healthcare facilities

• Retail stores

• Grocery stores

• Warehouses

• Office buildings

• Government facilities

• Hospitality environments

• Commercial cleaning contractors

• Finished VCT floors

• Polished concrete with compatible diamond pads

• Large commercial floor areas
