Safety Information
- Always wear appropriate personal protective equipment, such as safety glasses, to protect against splashes and debris.
- Ensure the drill is unplugged or the battery is removed before attaching or detaching any brush.
- Do not apply excessive pressure, as this can damage the brush bristles or the surface being cleaned.
- Test the brush on an inconspicuous area first to ensure it does not scratch or damage the surface.
- Keep hands and loose clothing away from rotating parts.
- Do not use near electrical outlets or with liquids that could cause electrical hazards.
- Keep out of reach of children.
Setup Instructions
Follow these steps to properly attach the cleaning brushes to your cordless drill:
- Ensure Drill Compatibility: Verify that your cordless drill has a chuck that can securely hold a 1/4 inch hexagonal shaft. The connecting rod diameter for these brushes is 1/4 inch.
- Insert the Brush: Open the drill chuck and insert the hexagonal shaft of the desired brush or the extended reach attachment into the chuck.
- Secure the Connection: Tighten the drill chuck firmly to ensure the brush is securely locked in place. For the extended reach attachment, insert it into the drill chuck first, then attach the desired brush to the other end of the extension.
- Verify Stability: Gently pull on the brush to confirm it is securely attached and will not come loose during operation.

General Usage
- Apply a suitable cleaning solution to the surface to be cleaned.
- Start the drill at a low speed and gradually increase as needed.
- Move the brush in a controlled manner over the surface, allowing the rotating bristles to do the work.
- For stubborn stains, allow the cleaning solution to soak for a few minutes before scrubbing.
- Use the extended reach attachment for hard-to-reach areas or to reduce bending.
Cleaning Applications
The versatile brushes are effective for a wide range of cleaning tasks:
- Large Flat Surfaces: Use the larger flat brushes for bathtubs, shower walls, floors, and large tile areas.
- Corners and Gaps: The smaller brushes and cone-shaped brush are ideal for grout lines, tight corners, and crevices.
- Automotive: Clean car wheels, tires, and other automotive surfaces.
- Kitchen: Tackle stove grates, drip pans, and sink areas.
- Upholstery: Use appropriate brush firmness for upholstery cleaning (test first).

Maintenance and Care
- After each use, rinse the brushes thoroughly with water to remove any cleaning solution or debris.
- Allow the brushes to air dry completely before storing to prevent mildew or odor.
- Store the brushes in a dry place, away from direct sunlight and extreme temperatures.
- Inspect brushes regularly for wear and tear. Replace brushes when bristles become excessively worn or damaged to maintain cleaning effectiveness and prevent surface scratching.
Troubleshooting
- Brush not fitting drill: Ensure your drill chuck is compatible with a 1/4 inch hexagonal shaft. If not, the brush set will not be suitable for your drill.
- Brush spinning loosely: Re-tighten the drill chuck securely. If the internal connection of the brush itself is damaged, the brush may need replacement.
- Ineffective cleaning: Ensure you are using the correct brush firmness for the surface and stain type. Apply an appropriate cleaning solution and allow it to work before scrubbing.
- Bristles bending or flattening: This is normal wear over time, especially with frequent or heavy use. Softer bristles may show wear faster. Replace brushes as needed.
