How to Replace an Orbital Sander Pad (Bosch ROS20VS) — Easy DIY Guide

How to Replace the Hook‑and‑Loop Pad on Your Orbital Sander

If your sanding discs keep flying off or refusing to stick, you’re not alone. Over time, the hooks on an orbital sander’s pad can melt or wear down — especially if you apply too much pressure or sand on the edge of the pad. The good news is that replacing the hook‑and‑loop pad is quick, inexpensive, and can make your sander feel brand new again.

In this guide, we’ll walk through how to replace the pad on a Bosch ROS20VS random orbital sander, but the process is nearly identical for most brands and models.

Why Your Sanding Discs Stop Sticking

Over time, the tiny hooks on the pad wear out or melt away, leaving the surface slick and unable to grip sanding discs. Common causes include:

• Pressing down too hard while sanding

• Bogging down the motor

• Sanding on the sander’s edge (a big no‑no)

Replacing the pad restores proper grip and prevents discs from flying off mid‑project.

What You’ll Need

• Replacement hook‑and‑loop pad (match your sander’s brand + model)

• Torx bit driver (the Bosch pad uses four Torx screws)

• Optional: compressed air or brush for cleaning

You can find replacement pads on Amazon by searching your sander’s brand, model number, and “hook and loop pad.” They’re available in singles, two‑packs, and multi‑packs.

Step‑by‑Step: How to Replace the Pad

1. Remove the Old Pad

Flip the sander over and remove the four Torx screws holding the pad in place. The screws aren’t very tight, so they should come out easily.

2. Clean the Sander Base

With the pad off, take a moment to clean out dust and debris from the base of the sander. This helps the new pad sit flush and last longer.

3. Install the New Pad

Align the new pad with the screw holes and reinstall the four screws. Avoid overtightening — too much torque can strip the threads.

4. Test the Grip

Attach a sanding disc and check the traction. A fresh pad should hold the disc firmly with no slipping or flying off during use.

Tips to Make Your New Pad Last Longer

• Let the sander do the work — apply only light pressure

• Avoid sanding on the edge of the pad

• Keep the pad clean and free of debris

• Replace discs before they’re overly worn

These small habits dramatically extend the life of your hook‑and‑loop pad.

Final Thoughts

Replacing an orbital sander pad is one of the easiest maintenance tasks you can do in your shop — and it can save you from buying a whole new tool. With just a Torx driver and a few minutes, your sander will be back to gripping discs like new.
