7 Best Car Polishers and Buffers

You know that there are plenty of “TOP 10” lists and similar, but I think that only these 7 are “the best” ones for this price range.

1. Rupes LHR 15ES Big Foot Random Orbital Polisher – BEST OVERALL

The Rupes LHR 15ES isn’t just another car polisher — it’s my personal favorite for an affordable yet quality finish. With Rupes’ reputation for excellence since 1947, this Italian masterpiece is a game-changer for paint correction.

As a dual-action orbital polisher, it’s a godsend for beginners like I was once, virtually eliminating the fear of damaging your car’s paint. Its 15-millimeter throw is tailored for 6-inch pads, which I’ve found to cover areas large and small with equal finesse.

At 500W, with RPM settings from 1700 to 4200, it has never failed me, whether I’m tackling a quick buff or a thorough shine. Its design is intuitive—during my use, it’s proven its worth on a variety of paint colors, always resulting in that flawless finish.

Despite not being the cheapest, the value it provides is unmatched. For under $300, I can vouch for the Rupes LHR 15ES as the best professional car polisher on my shelf. The glowing reviews are no surprise; it really is that good.


  • Reputable company
  • High-quality product
  • Great design
  • Best in this price tag
  • For both beginners and professionals


  • Some people complain that it’s a bit heavy

2. Black+Decker WP900 6 Inch Random Orbit Polisher – BEST BUDGET

BLACK+DECKER Buffer Polisher, 6 inch Orbital Car Polisher, with Wool or Foam Bonnets (WP900)
Amazon Prime

The Black+Decker WP900 is a solid pick for those who need a dependable polisher without breaking the bank. From my experience with their cordless drill, which punches well above its weight for the cost, I expect their polishers to follow suit.

This unit shines when it comes to wax application and light polishing tasks. However, if you’re in the market for something that can handle heavy compounding, you might want to look elsewhere.

With its 4,400 OPM capability, I’ve found it delivers a smooth, swirl-free finish rapidly. Its random orbital nature means it’s safe for your car’s paint—no worries about burns here.

The package comes with two bonnets: a foam one for waxing and a wool one for polishing, which I’ve found to be quite handy.

And let’s talk about durability. It’s backed by a 2-year warranty, but in my experience—and I’ve heard the same from folks who use it professionally—it can withstand 3-4 years of rigorous use. For an entry-level polisher, that’s impressive longevity.


  • Very cheap polisher
  • 2-year warranty
  • 2 pads included


  • Not the best for compounding
  • You can’t adjust the speed

3. DeWalt 20V Max XR Cordless Random Orbit Polisher – BEST CORDLESS

DEWALT 20V MAX* XR Cordless Polisher, Variable-Speed, Random Orbit, 5-Inch, Tool Only (DCM848B)

The DeWalt 20V Max XR Cordless Polisher stands out as an exceptional choice for those seeking a high-quality cordless random orbital polisher. Its portability is a significant plus, making it an essential tool for mobile car detailers like myself.

With a 5″ backing plate that’s well-suited for a wide range of tasks and a speed range of 2,000-5,500 OPM, it provides versatility and control. The variable speed trigger is something I particularly appreciate, allowing for quick adjustments to match the task at hand.

I’m also a fan of the ergonomic design. The polisher’s side handle and front-grip area offer multiple holding positions, ensuring comfort and efficiency during use.

Bear in mind that batteries are sold separately, but if you’re already using DeWalt tools, you might have compatible batteries. Even with the additional purchase of batteries, the polisher’s price remains reasonable, especially given its performance and the flexibility it adds to my detailing toolkit.


  • Great features for the price
  • All DeWalt 20v batteries are compatible with this device
  • Rubbed design for easier handling


  • Batteries not included

4. Adam’s Swirl Killer 15mm Car Polisher

Adam's Polishes Swirl Killer 15mm Car Polisher - Buffer Polisher Dual Action Machine | Use W/Car...

Adam’s Swirl Killer 15mm Polisher is an exceptional choice for those seeking a high-quality finish without the high-end price tag. It excels in eliminating swirls, scratches, and paint imperfections and is equally effective for applying glazes, sealants, and waxes to bring out your car’s best look.

For beginners or those cautious about paint correction, this dual-action polisher is incredibly forgiving and user-friendly. With a substantial 15mm throw and adjustable speeds up to 4,800 OPM, it includes a slow-start function to minimize splatter and allows for fine-tuned control with six speed settings. My experience confirms it works seamlessly with 5.5″-6″ microfiber and foam pads, adaptable for a range of detailing jobs.

What I appreciate about the Swirl Killer is its generous 25ft power cord, which effortlessly extends around the car for a hassle-free detailing experience. Its size strikes the perfect balance, robust enough to tackle large areas efficiently, yet agile for precision work in snug spots.

If the Rupes LHR 15ES is beyond your budget, Adam’s Swirl Killer is a fantastic alternative, nearly $100 cheaper. In my hands-on experience, it stands up commendably to its pricier counterparts, providing professional results without breaking the bank.


  • Reputable company
  • Dual-action polisher with up to 4,800 RPM
  • Great build quality
  • Fantastic value for the price (it costs less than Rupes and Flex, but it’s the same quality)


  • They say that you should use only Adam’s polishes and compounds, which is only a marketing trick

5. Chemical Guys BUF_503X TORQX Random Polisher Kit

Chemical Guys BUF 503X TORQX Random Orbital Polisher, Pads, Polishes & Compounds Kit (Safe for Cars,...

The Chemical Guys TORQX Random Polisher Kit is a comprehensive set that’s perfect for anyone looking for a complete polishing solution. With this kit, you’ll receive a versatile random orbital polisher along with an assortment of pads, polishes, and compounds, ensuring you’re well-equipped for any detailing task.

Boasting a 680W motor, the TORQX offers a wide RPM range of 2,800-7,800, along with an OPM spectrum from 1,200-4,200, providing ample power and control for various polishing jobs. The flexibility to switch between 3.5″ and 6″ pads allows for tailored detailing, whether you’re working on larger surfaces or intricate areas.

For the weekend warriors of car detailing, this kit hits the sweet spot. It packs everything you need for that initial paint correction project in one convenient package. From my personal experience with this buffer, I can attest to its reliability and performance. While the included polishes and compounds are somewhat small, they’re sufficient to get started.

Based on value for money, if my budget was capped at $200 for a polisher and buffing pads, the TORQX kit would be my top pick. It offers a robust, cost-effective option that doesn’t disappoint, and I’ve consistently achieved excellent results with it. It’s a standout choice for those looking to get maximum bang for their buck.


  • Very affordable price
  • You get everything you need
  • Great for beginners


  • The polisher is very loud

6. DeWalt DWP849X Rotary Polisher

DEWALT Buffer Polisher, 7”-9”, 12 amp, Variable Speed Dial 0-3,500 RPM’s, Corded (DWP849X)

The DeWalt DWP849X Rotary Polisher is an exceptional tool for professional detailers who value power and affordability. With a robust 1,200W motor, it offers the strength needed for serious detailing work.

Its speed spectrum, ranging from 0-600 to 0-3,500 RPM, is enhanced by a soft start function for more refined control and finishing. Although its rotary action requires some proficiency, it’s incredibly effective for quick polishing or compounding on large areas like vehicle roofs and hoods, especially when using 7″ pads.

Drawing from my own early detailing days, I recall using a similar DeWalt rotary polisher. Despite its excellent capabilities, a momentary lapse led to burning the clear coat on a spare part while I was learning the ropes. Hence, I advise beginners to opt for a different model to avoid such mishaps. For those with the know-how, the DeWalt DWP849X is a potent, reliable machine that promises to be a workhorse in your detailing endeavors.


  • High-quality rotary polisher
  • Excellent choice for professionals
  • Very powerful
  • 90 days money-back guarantee


  • Not convenient for smaller areas

7. Makita 9237CX3 Rotary Polisher Kit

The Makita Rotary Polisher Kit offers robust performance for seasoned detailing enthusiasts. Its 7″ size makes it ideal for tackling large areas, and the 10-amp power easily powers through any detailing project. The variable speed control ensures you can adjust to the task at hand, while the soft start feature provides a safeguard against sudden movements, preserving the integrity of your paintwork.

This kit comes with everything you need to get started, including a variety of pads to suit different tasks. It’s a quality tool for those who know their way around a polisher and need something reliable for extensive use.

Just as I mentioned with a previous product on the list, beginners should approach with caution. Without proper technique and a gentle hand, you risk damaging the paintwork by burning through the clear coat. It’s advisable to gain proficiency with these tools on less critical projects before applying them to your main detailing jobs.


  • Multi-purpose device
  • Amazing build quality
  • Great reviews


  • Too large for smaller detailing tasks

Car Polishers Buyer’s Guide

If you’re a beginner, I suggest you first read this buyer’s guide before buying a new polisher. Pay attention to these things when deciding which polisher to buy.

Types of Polishers

  • Rotary Polishers. Rotary Polishers work in a circular motion and are usually more powerful. However, there’s a chance of burning through if you’re not careful enough. With a rotary polisher, you can get better results, but you need to know how to work with it.
  • Dual-Action Polishers. Dual-action polishers work in orbital motion, so there’s no fear of burning the paint. It’s the best choice for beginners. If you’re not familiar with polishers, I suggest you always choose a dual-action polisher. Even professionals are mainly using dual-action polishers.
rotary vs da polisher differences


  • When you decide whether you need a rotary or a dual-action polisher, you should pay attention to handles.
  • Some polishers are very easy to handle, and some are not. Look for some polisher that you can hold in a few ways with your other hand. That way, you’ll quickly adapt to any car detailing situation.


  • You should always choose a polisher that has adjustable speed settings (RPM).
  • That’s going to allow you to adjust the polisher’s RPM, depending on the detailing task you’re working on. Most polishers have speeds ranging from 1-6.
  • The bigger the range of RPM, the better. Usually, you’ll find that most polishers have a speed range of 500 – 4,000 RPM.
  • Somewhere, you’ll see RPM, and somewhere OPM. It’s actually the same thing, but RPM (revolutions per minute) is mostly used in Rotary polishers, while OPM (operations per minute) is used on Orbital polishers.
  • There’s no definitive answer to what the best RPM or OPM on polishers is; I just wanted to show you what that means.


  • Rotary polishers are usually more powerful (around 1000-1200 Watts), while dual-action polishers are generally around 600-700 Watts. 
  • So, if you see some polisher that’s 100 Watts, it’s probably not powerful enough.

Power Cord Length

  • This is also one of the factors to consider when buying a new auto detailing polisher. 
  • Depending on your needs, you might want to choose a polisher with a longer power cord. Some medium sizes are 20-25ft.
  • Of course, if you’re buying a cordless polisher, then you don’t need to worry about it. 

Wrap Up

To wrap this up, I’ll just say this: Rupes is my top pick for a reason. It’s a solid, reliable machine that delivers quality results, which is what you’re after when you’re working on a car’s paint.

But don’t sweat it if the price tag feels steep right now. You can start with something more budget-friendly and work your way up. The most important thing is to get a polisher that gets the job done without overcomplicating things.
