The GRIOTS G15 polisher uses a rotating brush to polish stainless steel, car parts, and other steel equipment’s. It is a highly advanced tool designed to restore shine and smoothness back to stainless steel, leaving it looking like new again. The G15 polisher is a professional grade machine, providing superior quality with unmatched performance and ease of use. Its unique design features include the patented “pulsing” brush that rotates back and forth at a rate of 3,500 rpm, and the built-in water level gauge to ensure proper cleaning. The result is stainless steel sinks that are shining clean, looking their best and easy to maintain.

GRIOTS G15 polisher is a small-scale polisher that is designed to be used by individuals and small teams who need high-end, high-performance polishing. It is powered by a 15-watt motor, and comes with a variety of accessories including a plastic cover, a microfiber cloth, an auto-reverse brush, and a cleaning brush. It is suitable for use in both wet and dry conditions, and can be used as a handheld tool, as a benchtop machine, or attached to a robotic arm. Its ergonomic design allows you to use it for extended periods without discomfort.

G9 Vs G15 Technical & Performance Differences

This new generation GRIOTS is a lot different from its predecessor. It comes with the latest technological features such as; a microprocessor, a ceramic diamond abrasive system and a water cooled motor system. All this adds up to a performance improvement of +35% in comparison to the older GRIOTS polishers.

One thing’s for sure you won’t get much of a polish out of a regular G9. It’s no secret that the best tools for cleaning up the surface of your car come with diamond abrasive. But the GRIOTS G9 car polisher and the GRIOTS G15 car polisher are two different tools designed to do different jobs.

The GRIOTS G9 car polisher is a high-speed rotary car polisher that uses diamond abrasive to clean the surface of your car. It’s easy to use, and it’s good for removing minor scratches and surface marks. The GRIOTS G15 car polisher is a rotary car polisher that uses a combination of diamond and aluminum oxide to clean the surface of your car. It’s ideal for removing deeper scratches and stains. It’s the better choice for a professional-grade polish.

The GRIOTS G9 is our entry level GRIOTS and the GRIOTS G15 is our advanced model. Both come with our patented dual mode rotary technology that gives you more control over the grit and finish level. The G9 has 10-degree angle of rotation while the G15 offers 15-degrees. Both models can achieve a fine polish up to 600 microns and a high-gloss finish up to 2500 microns. This means they will remove scratches to bare metal, even if you run your hand over them.

The two machines are similar in design and purpose, but the differences are subtle. Both feature an automatic motor with a motorized head that uses diamond abrasive to polish surfaces. The G9 and G15 differ in the motor speed, motor power, head size, and the number of tools (G15) available to perform the task.

The GRIOTS G9 is for all-around maintenance and the GRIOTS G15 is used for polishing hard and soft surfaces. Both models are versatile machines that can work on all surfaces and come with a variety of accessories and attachments. Both models use the same motor, but GRIOTS G9 is a single-stage machine while GRIOTS G15 has two stages and uses a 3-axis brush.

GRIOTS G9 vs. G15. Which one is better?

There’s no denying that GRIOTS G15 is a serious performer. With an output rating of 16 microns, it’s capable of reaching a polish finish on bare metal and ceramic surfaces, as well as removing rust, oxidation, and stains. It’s also easy to use, with its four-directional cleaning pad, and comes with a convenient storage tray.

A lot of people ask me which one is better for their particular situation. It depends on what type of car you drive. In this case, the answer is clear – the G15 is better. Why? Because the G15 can do two or three things that the G9 cannot. The G15 is a stand-alone, single-use tool, whereas the G9 requires a cloth to clean it. The G9 does not come with a brush attachment and a cleaning solution. It only comes with a cloth, because you have to buy them separately.


In conclusion, if you’re looking for a super affordable alternative to the GRIOTS G15, I’d recommend looking at the GRIOTS G9 which is similar, but a little cheaper. If you’re looking for something that looks better than the GRIOTS G15, then I’d recommend going for the GRIOTS G15. The GRIOTS G9 is good, but it doesn’t look as polished as the GRIOTS G15 and the finish isn’t as smooth.
