The VIPER AS510B, product number 56384775, is designed for facilities that need the productivity of an automatic scrubber in a relatively compact walk-behind format.

Its combination of a 20-inch disc cleaning path, 10.5-gallon tanks, strong brush pressure, pad-assist operation, and compact dimensions makes it useful for schools, offices, commercial kitchens, retail areas, and other facilities where maneuverability is important.

Machine-Only Configuration

This 56384775 configuration is supplied without batteries.

A compatible battery package must be selected and installed before the machine can be operated.

This allows the battery system to be chosen according to:

• Desired runtime

• Battery maintenance preference

• Facility operating schedule

• Existing equipment standards

• Replacement requirements

9-Amp Onboard Charger

The AS510B includes a 9-amp onboard charger.

Once compatible batteries are installed, the onboard design allows the charging system to remain with the machine rather than requiring a separate shelf charger.

20-Inch Disc Cleaning System

The AS510B uses a 20-inch disc cleaning deck.

This size provides a useful balance between productivity and maneuverability for:

• Routine hard-floor cleaning

• Corridors

• Classrooms

• Retail areas

• Commercial kitchens

• Offices

• Dining areas

• Other medium-size commercial spaces

Pad Driver Included

This configuration includes a 20-inch pad driver.

Compatible floor pads can be selected according to the floor surface, soil level, and cleaning procedure.

Pad-Assist Drive

The AS510B uses pad-assist operation rather than powered traction.

Rotation of the pad or brush helps pull the machine forward, reducing the effort required to move the scrubber during normal operation.

77 Lbs. Brush/Pad Pressure

The cleaning deck applies approximately 77 lbs. of pressure.

This provides substantial mechanical cleaning action for everyday commercial maintenance and more demanding floor conditions.

150 RPM Brush Speed

The cleaning deck operates at approximately 150 RPM.

The combination of moderate rotational speed and strong down pressure provides effective agitation across compatible hard-floor surfaces.

10.5-Gallon Solution Tank

The AS510B carries approximately 10.5 gallons of cleaning solution.

This provides useful cleaning capacity while keeping the overall machine smaller than larger 16-gallon-class walk-behind scrubbers.

10.5-Gallon Recovery Tank

A matching 10.5-gallon recovery tank collects dirty solution during operation.

The balanced tank capacities support efficient one-pass scrubbing and recovery.

31-Inch-Class Cast Aluminum Squeegee

The rear squeegee measures approximately 31.1 inches wide.

Its heavy-duty cast aluminum construction is designed for regular commercial use, while the rounded shape helps maintain solution recovery during normal maneuvering.

Up to 15,748 Sq. Ft. Per Hour

The AS510B has a published productivity rating of up to approximately 15,748 square feet per hour.

Actual productivity will vary based on:

• Facility layout

• Travel speed

• Soil conditions

• Obstacles

• Refill and dump stops

• Operator technique

Compact Maneuverability

At approximately 47 inches long and 24 inches wide, the AS510B remains relatively compact for a 20-inch automatic scrubber.

This makes it easier to maneuver:

• Around tables and chairs

• Through corridors

• Around corners

• Between fixtures

• In congested commercial spaces

Intuitive Fingertip Controls

Primary operating controls are positioned beneath the handle for convenient access.

The straightforward layout helps simplify operator training and daily use.

• Schools

• Offices

• Retail stores

• Shopping centers

• Commercial kitchens

• Restaurants

• Hotels

• Healthcare facilities
