The VIPER AS1050R-420 is designed for very large commercial and institutional facilities where productivity, runtime, and tank capacity are critical.

As VIPER’s large ride-on scrubber platform, the AS1050R combines a 39-inch-class cleaning path, 53-gallon tanks, high-capacity battery power, adjustable brush pressure, and powered traction to efficiently maintain expansive floor areas while remaining maneuverable for its size.

420Ah Wet Battery System

This AS1050R configuration includes 420Ah wet batteries.

The large-capacity battery package is designed for extended cleaning shifts and supports up to approximately 5 hours of operation in ECO mode, depending on operating conditions and machine settings.

Runtime can vary with:

• Brush pressure

• Travel speed

• Vacuum use

• Floor condition

• Battery condition

• Cleaning mode

39-Inch-Class Scrubbing Width

The AS1050R uses two 20-inch brushes or pad drivers to provide an approximately 38.6-inch / 39-inch scrubbing path.

The wide deck makes the machine especially productive in:

• Retail stores

• Schools and universities

• Warehouses

• Distribution facilities

• Manufacturing environments

• Large healthcare facilities

• Convention and event spaces

• Other expansive commercial buildings

53-Gallon Solution and Recovery Tanks

Large 53-gallon solution and recovery tanks allow longer cleaning cycles between refill and dump stops.

The high-capacity tanks are especially valuable in large facilities where repeatedly returning to a janitorial closet or fill station can significantly reduce productivity.

Up to 84,389 sq. ft./hr. Productivity

VIPER rates the AS1050R for productivity of up to approximately 84,389 square feet per hour under suitable operating conditions.

Actual productivity will vary based on:

• Travel speed

• Floor layout

• Obstacles

• Turning

• Refill and dump requirements

• Soil conditions

• Operator technique

Adjustable Brush Pressure

Brush pressure can be adjusted from approximately 110 to 198 pounds.

Lower pressure can be selected for routine maintenance, while additional pressure provides more aggressive mechanical cleaning for heavily soiled floors.

Dual 20-Inch Scrub Heads

Two 20-inch disc brushes or pad drivers rotate at approximately 240 RPM.

The dual-disc design combines a wide cleaning path with strong mechanical agitation for commercial floor cleaning.

One-Touch™ Operation

The AS1050R includes VIPER’s One-Touch™ control system.

A simplified control layout allows primary cleaning functions to be activated quickly, reducing the number of individual steps required when beginning a cleaning pass.

LCD Operator Display

The integrated LCD display provides an at-a-glance overview of machine operation.

This allows operators to monitor settings and machine status from the seated operating position.

ECO Mode

ECO mode is designed to balance:

• Battery consumption

• Cleaning performance

• Solution usage

• Operating time

This helps extend runtime during routine maintenance cleaning.

Silent Mode

For environments where noise must be controlled, the AS1050R includes a Silent Mode.

The machine’s listed sound-pressure level is approximately 72 ± 3 dB(A) under standard operating conditions.

Powered Traction Drive

A 2.1 HP traction motor powers the machine forward and in reverse.

This reduces operator effort and allows efficient travel across large facilities.

Maximum travel speed is approximately 5 mph.

Safety-Focused Drive System

The AS1050R incorporates several features designed to improve handling and safety, including:

• Automatic speed reduction during turns

• Automatic braking

• Mechanical braking

• Rugged protective bumpers

• Controlled forward and reverse traction

Large-Area Maneuverability

Despite its large tank and scrub-deck capacity, the AS1050R is designed to remain maneuverable for a ride-on scrubber in this class.

Its minimum aisle turning requirement is approximately 104 inches.

Climbing Capability

The AS1050R is rated for:

• Up to 20% maximum climbing capability

• Up to 16% maximum working climbing rate

Always follow manufacturer operating guidance when working on ramps or inclines.

Effective Water Recovery

The rear squeegee assembly works with the vacuum system to collect spent cleaning solution after the scrub deck passes over the floor.

This helps leave the floor cleaner and drier after each pass.

Easy Maintenance Access

The machine is designed to provide convenient access to commonly serviced components.

Simplified maintenance access can reduce downtime and make routine inspections easier for facility staff.

Professional Applications

The VIPER AS1050R-420 is well suited for:

• Large retail stores

• Schools and universities

• Warehouses

• Distribution centers

• Manufacturing facilities

• Hospitals and healthcare campuses

• Airports and transportation facilities

• Convention centers

• Government buildings

• Commercial cleaning contractors

• Facilities with more than 75,000 sq. ft. of maintained floor area
