The NSS Charger 2717 AB 6402723 is a 27-inch battery-powered walk-behind burnisher with pad-assisted propulsion, a 220AGM battery system, onboard charger, 1700 RPM pad speed, 80 pounds of pad pressure, and integrated Vac-Trac dust control.

Features:

• Pad-Assisted AB Configuration – The defining feature of the Charger 2717 AB, using an angled pad motor to help pull the machine forward during operation.

• Onboard Charger (OBC) – Keeps the charging system with the machine for easier day-to-day battery charging.

• 220AGM Battery Configuration – Uses sealed AGM batteries for lower routine maintenance and cordless commercial operation.

• 27-Inch Working Width – Covers a wide floor area with each pass for productive maintenance of large facilities.

• 1700 RPM Pad Speed – Provides high-speed burnishing performance for restoring gloss to compatible floor finishes.

• 80 lb. Pad Pressure – Combines substantial floor pressure with high pad speed for effective polishing.

• Vac-Trac Dust Control System – Captures floor-finish powder generated during burnishing directly at the pad-motor shroud.

• Suitable for Concrete Polishing – Powerful motor performance makes the Charger 2717 suitable for use with compatible Twister diamond pads.

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

• Battery-Electric Operation – Eliminates propane exhaust, fuel handling, oil changes, and combustion-engine maintenance.

• Wide-Area Productivity – The 27-inch platform is designed for larger open spaces where narrower burnishers require more passes.

• Lower Routine Maintenance Requirements – Electric operation reduces many of the service demands associated with propane burnishers.

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

The NSS Charger 2717 AB 27-Inch Walk-Behind Auto Burnisher 6402723 is designed for facilities that need wide-area battery burnishing without moving to a ride-on machine.

The AB version uses an angled pad motor to help pull the machine forward, giving the operator pad-assisted movement rather than the dedicated wheel-drive system used on the Charger 2717 DB.

This configuration also includes a 220AGM battery system and onboard charger, while retaining the Charger 2717 family’s 27-inch working width, 1700 RPM pad speed, 80 pounds of pad pressure, and Vac-Trac dust control.

Pad-Assisted AB Drive

The primary difference between the Charger 2717 AB and DB models is how the machine moves.

The 2717 AB is pad-assisted. NSS angles the pad motor so the rotating pad helps pull the burnisher forward during operation.

This provides forward assistance without adding the dedicated wheel-drive motor found on the DB version.

Onboard Charger

Model 6402723 includes an onboard charger.

Keeping the charger built into the machine eliminates the need to store and manage a separate external charger and can simplify daily charging routines.

220AGM Battery System

The machine uses a 220AGM battery configuration.

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

Benefits include:

• No routine battery watering

• Sealed construction

• Reduced battery maintenance

• Clean cordless operation

27-Inch Working Width

The Charger 2717 provides a 27-inch working width.

The wider pad helps increase productivity in large open areas by reducing the number of passes required compared with narrower walk-behind burnishers.

1700 RPM Burnishing Speed

The Charger 2717 operates at approximately 1700 RPM.

This high-speed pad rotation is designed to restore the glossy appearance of compatible finished hard floors after scrubbing and routine maintenance.

80 lb. Pad Pressure

The machine applies approximately 80 pounds of pad pressure.

The combination of high speed and substantial pad pressure helps the Charger 2717 efficiently restore floor-finish luster.

Vac-Trac Dust Control

High-speed burnishing can generate fine floor-finish powder.

The Charger 2717 incorporates NSS’ Vac-Trac Dust Control System into the pad-motor shroud to capture this debris during operation.

This helps reduce loose dust left behind after burnishing.

Concrete Polishing Capability

NSS also identifies the Charger 2717 as suitable for concrete polishing with compatible Twister diamond pads.

This expands its usefulness beyond conventional floor-finish burnishing for facilities maintaining polished-concrete surfaces.

Battery-Electric Operation

The Charger 2717 uses battery-electric power instead of propane.

This eliminates the need for:

• Propane fuel purchases

• Fuel-cylinder storage and handling

• Engine oil changes

• Combustion-engine maintenance

• Indoor propane exhaust during operation

68 dB(A) Sound Level

The Charger 2717 operates at approximately 68 dB(A).

Its relatively quiet electric operation makes it suitable for many commercial environments where floor maintenance may occur during extended operating hours.

Professional Applications

The NSS Charger 2717 AB is well suited for:

• Schools and universities

• Hospitals and healthcare facilities

• Retail stores

• Grocery stores

• Warehouses

• Office buildings

• Airports

• Convention facilities

• Government buildings

• Commercial cleaning contractors

• Finished VCT floors

• Polished concrete with compatible diamond pads
