The NSS Galaxy 20DS N0302020 combines the productivity of a wider 20-inch working width with the versatility of dual-speed 180/300 RPM operation.

The lower speed is designed for more aggressive floor-care procedures such as scrubbing and stripping, while the higher speed is useful for polishing and carpet bonnet cleaning.

With its 1.5 HP motor, precision-balanced construction, and durable commercial design, the Galaxy 20DS is a practical choice for facilities that want one machine capable of handling a broad range of floor-care tasks.

20-Inch Working Width

The Galaxy 20DS uses a 20-inch / 51 cm working width.

Compared with the 17-inch Galaxy models, the wider platform covers more floor with each pass and can improve productivity in larger open areas.

Dual-Speed 180/300 RPM Operation

The defining feature of the Galaxy 20DS is its two-speed operation.

The operator can switch between:

• 180 RPM for scrubbing, stripping, and general low-speed floor care

• 300 RPM for polishing and carpet bonnet cleaning

This allows one machine to handle a wider range of maintenance procedures than a traditional single-speed floor machine.

1.5 HP Commercial Motor

The Galaxy 20DS uses a 1.5 HP / 1110-watt motor.

The heavy-duty motor provides dependable power for repeated commercial applications ranging from aggressive stripping to routine polishing.

120V, 50/60Hz Electrical Configuration

This model is designed for 120V electrical service and is rated for 50/60Hz operation.

Always verify that the available electrical service matches the machine requirements before use.

Precision-Balanced Design

The Galaxy is precision balanced to provide smooth, predictable handling.

Proper balance helps make the larger 20-inch platform easier to control during extended floor-maintenance procedures.

Durable Steel Skirt

A chrome-plated steel skirt surrounds the machine base.

This adds durability in an area frequently exposed to contact with walls, furniture, fixtures, and other obstacles.

Mechanical Safety Lock-Out

A mechanical lock-out switch helps prevent accidental machine startup.

This adds an important measure of safety during setup, handling, transportation, and storage.

Quiet Commercial Operation

The Galaxy operates at approximately 58 dB(A).

Its relatively low sound level can be useful in schools, healthcare facilities, offices, and other environments where cleaning may occur during occupied hours.

Professional Applications

The NSS Galaxy 20DS is well suited for:

• Schools and universities

• Hospitals and healthcare facilities

• Office buildings

• Retail stores

• Hospitality environments

• Government facilities

• Commercial cleaning contractors

• Finished hard floors

• Carpet bonnet cleaning

• Carpet shampooing with appropriate accessories

• Large open commercial areas
