Description

Rainbow RX201 Brush Roll

The Rainbow RX201 Brush Roll is a replacement power-nozzle roller brush for select older Rainbow and Rexair vacuum systems. It is commonly used in D3C and D4C-series power nozzles and is cross-referenced under several part numbers, including 78-3405-02, R1866, and RR-2000.

This replacement brush roll is designed for power nozzles where the drive belt is located at the end of the brush roll.

Designed for Older Rainbow Power Nozzles

This brush roll is especially useful for customers maintaining older Rainbow vacuum systems that are still in service.

Compatible power nozzles include models used with D3C and D4C-series Rainbow systems. One current specialist listing describes the RX201 as fitting D3C, D4C, D4C SE, R1650C, R2800C and R4375C power heads. :contentReference[oaicite:2]{index=2}

End-Drive Belt Configuration

The Rainbow RX201 Brush Roll uses an end-drive belt configuration, meaning the belt rides on the pulley located at the end of the brush roll.

This detail is important because Rainbow used different brush-roll and belt arrangements across different power-nozzle generations.

Why Replace a Worn Rainbow Brush Roll?

A worn or damaged brush roll can reduce carpet agitation and cleaning performance.

Common signs that the brush roll may need replacement include:

• Worn or shortened bristles
• Uneven brush contact with carpet
• Cracked or damaged roller body
• Excessive vibration or noise
• Worn end caps or bearings
• Poor pickup even with good suction

Improves Carpet Agitation

The brush roll is responsible for agitating carpet fibers so embedded dirt, hair and debris can be lifted into the airflow of the power nozzle.

Replacing a heavily worn brush roll can help restore the cleaning performance of an older Rainbow power head.

Approximate Brush Roll Size

Current listings describe the RX201 brush roll as approximately 13 to 14 inches long from end cap to pulley end, depending on how it is measured. :contentReference[oaicite:3]{index=3}

Fits R1650C Power Nozzle

The Rainbow RX201 Brush Roll is commonly listed for the R1650C power nozzle.

Fits R2800C Power Nozzle

Compatible with D3C and D4C Systems

The RX201-style roller is also commonly used with power nozzles found on:

• Rainbow D3C systems
• Rainbow D4C systems
• Rainbow D4C SE systems

Always identify the power-nozzle model itself when possible, since Rainbow vacuum systems could sometimes be paired with different nozzle versions.

Verify Before Ordering

Before ordering, compare:

• Your power-nozzle model
• Your existing brush-roll part number
• Belt location
• Brush-roll length
• End-cap style

This helps make sure you receive the correct brush roll for your Rainbow power nozzle.
