I’m sanding my floor with a Bosch GET75-6, a new orbital sander I purchased, and it seemed to be more effective when I leaned it on the edge of the sander vs. placing it flat on the ground. But this made me wonder if I was using the proper technique and/or going to damage the device.

So I recorded a video of how I was using the device and asked ChatGPT to provide guidance. (Note: to upload a video from an iPhone to ChatGPT, you have to move it to the iOS Files app – you can’t open it directly from the Apple Photos app, as of April 11, 2025.) Specifically, I asked and uploaded the following:

Which is the best way to proceed in terms of technique?

And to my surprise, ChatGPT actually analyzed the video rapidly and provided this response:

Thanks for the video — I’ve reviewed it. Here are some technique suggestions and feedback to help you get the best performance out of your Bosch GET75-6 HD sander:

What You’re Doing Well:

Even pressure: You’re not pressing too hard, which protects the motor and helps the tool do the work — perfect. Flat pad contact: The sanding pad is mostly staying flush with the surface, ensuring consistent abrasion. Control: Your grip and movement show you’re in control of the sander and not letting it get away from you.

Recommendations for Improved Technique:

Slower, Consistent Passes You’re moving the sander a bit quickly across the surface. Try slowing down to about 1 inch per second. This allows the abrasive to do more efficient work without having to go over the same area multiple times. Overlap Each Pass Make each pass overlap the last by about 30–50%. That creates an even finish and avoids uneven sanding patterns. Keep It Moving It’s good you’re not holding the tool in one place. Always keep it moving, especially on softer woods or finishes, to avoid swirl marks or heat spots. Let the Dust Extractor Help Keep that vacuum line fully clear and don’t let the hose tug or tilt the sander. It looked stable in the video, but it’s worth double-checking during long sessions. Avoid Tilting or Rocking Occasionally it looked like the pad was coming up at a slight angle. Even a small tilt can create unevenness. Try to keep even arm pressure from the wrist to the elbow, with light downforce centered.

Optional: Use the Two Modes Effectively

The GET75-6 has two modes:

Random Orbit for fine finishing Turbo (forced rotation) for aggressive removal

If you’re smoothing out wood and not trying to hog off a layer, stay in random orbit mode. If you’re stripping or flattening quickly, use turbo mode briefly but take more breaks and be careful with heat.

Let me know what material you’re sanding and your end goal — I can help fine-tune your grit progression and technique for the cleanest result.
