Our take on the Rupes BigFoot LHR15 Mark III Random Orbital Polisher

The Rupes BigFoot LHR15 Mark III is a corded dual-action polisher with a 15 mm orbit, built for professional paint correction on curved and varied panels. Its 500 W custom-wound motor holds 3,000-5,200 orbits per minute under load, and the progressive trigger and speed dial keep starts smooth. The 180-degree rotating handle and 2.6 kg body are meant to reduce fatigue over long sessions. At $456.99 at Detailer's Choice Car Care Products as of November 5, 2026, it sits at the low end of its recent range across the three stores that list it new.

About the Rupes BigFoot LHR15 Mark III Random Orbital Polisher

The RUPES BigFoot LHR15 MarkIII Built to handle any detailing situation, the new LHR 15 MarkIII is the new frontier of detailing. The ergonomic design allows for precise paint correction with complete comfort, in curved surfaces and difficult to reach areas. The LHR 15 MarkIII operates at a higher rpm compared to the LHR21 MarkIII. This increased speed provides equivalent correction and does so with a pad diameter and orbit that are more conducive to curved or varied surfaces. Here are just a few new features and benefits that the new line of MarkIII RUPES Polishers offers: Improved Ergonomics – Continuing inline with the RUPES mentality of improved balance, power, and comfort, the new grip and handle on the RUPES BigFoot LHR15 MarkIII Polisher will ensure that your hands and arms on not feeling the strain even if you’ve been polishing for HOURS (Which is not an unrealistic possibility!) Electronic Speed Control Dial – You don’t always need the most power the machine is capable of producing while you are polishing. You may not be cooking eggs, but sometimes “low and slow” is the right mentality when perfecting your paint. This speed control dial will allow you to adjust to the perfect speed for any and every job you come across! Progressive Trigger – When you are polishing paint for hours, having your polisher jump from 0 to 100 in the blink of an eye can be quite jarring and difficult to control, especially if you are working in tight areas! The Progressive Trigger on the RUPES BigFoot LHR15 MarkIII Polisher will give you the ability to ease into the top speed of the polisher. The more you squeeze it, the faster it will go, so you don’t have to worry about any unneeded slinging due to an unexpected kick from your polisher! Efficient Motor – This is probably the biggest bonus to the MarkIII polishers! The more efficient motor will let you buff to perfection in a fraction of the time it used to take! The correction potential of any polisher is limited by the power that polisher can produce. And with the ability to up to 5200 RPMs of balanced and consistent paint correction potential, you can be sure that the RUPES BigFoot LHR15 MarkIII Polisher is capable of tackling any polisher job!

Questions and answers

Is the LHR15 Mark III worth it over the Mark II?
The Mark III adds more torque, a redesigned grip and handle, and a progressive trigger. If your Mark II still runs well, the upgrade is mostly about comfort and control rather than raw correction speed.
How does it compare with the LHR21 Mark III?
The LHR15 has a smaller 15 mm orbit and runs at higher RPM, which suits curved and varied panels. The LHR21 covers large flat panels faster but is less nimble on contours.
What pads and backing plate does it take?
It uses standard Rupes BigFoot foam, wool and microfiber pads sized for its 15 mm orbit. Check that the backing plate matches your pad diameter before ordering.
Is it too much machine for a beginner?
It is aimed at professionals, and the higher RPM can mar soft paint in unpracticed hands. A hobbyist should practice on a scrap panel first.
When is it cheapest?
The best new price seen was $456.99 at Detailer's Choice Car Care Products as of November 5, 2026. Detailing suppliers discount most around holiday sales and bundle promotions.
