The Short Answer

The Mirka DEROS 5650CV is usually the best option for most professionals. Its larger orbit removes material faster, so it’s great for automotive refinishing, surface prep, and heavy-duty jobs. The 650CV is better for finish work where you need more control and a finer surface, rather than speed.

Both are high-end 6-inch (150mm) random orbital electric sanders in the $700 to $900 price range. They use the same Mirka pads and abrasives, and both offer top-notch vibration dampening and dust extraction.

Best for finish work and detail sanding: Mirka DEROS 650CV → Mirka 650CV on Amazon

Why This Comparison Matters

Both sanders cost about $700 to $900. If you’re a professional replacing an old sander or upgrading from a cheaper brand, choosing the wrong model can waste a lot of money. For shops buying several, the wrong choice could mean losing thousands.

It’s easy to see why people get confused. Both models use the Mirka DEROS platform, the same abrasives, have similar ergonomics, and connect to the same dust extraction systems. The main differences are the orbit size and the type of sanding you do most often.

This guide breaks down the differences in simple terms, shows which sander is best for each use, and gives clear recommendations based on how you work.

About the Mirka DEROS Platform

Both sanders belong to Mirka’s DEROS (Direct Electric Random Orbital Sander) line. This series raised electric sanders to the quality level once only found in air-powered tools, with three main advantages over pneumatic options:

No air compressor required. Pneumatic sanders need a serious compressor to run properly. DEROS sanders plug into a standard outlet, eliminating compressor noise, cost, and workspace footprint.

Lower vibration than most competitors. Mirka’s brushless motor and balanced construction produce vibration levels low enough that extended use is comfortable, which matters for professionals sanding for hours.

Built-in Bluetooth connectivity (on both models). Both sanders connect to the myMirka app for tracking vibration exposure, usage time, and maintenance intervals. This matters most for professional shops managing worker health exposure under HAVS (Hand-Arm Vibration Syndrome) regulations.

The 650CV and 5650CV are the top models in the DEROS lineup. Entry-level DEROS sanders are smaller and less powerful, but these two are full-size and full-power.

The Core Difference: Orbit Size

The biggest difference between these two sanders is the orbit size, which is how far the sanding pad moves during its random motion.

Mirka DEROS 650CV: 5 mm orbit; Mirka DEROS 5650CV: 5 mm orbit*

Note: Always check Mirka’s official product sheets for the latest specs before buying. In the DEROS line, the first digit of the model number shows the orbit size, so specs can change over time.

Orbit size decides what type of sanding each tool is best for:

Smaller orbit (5mm): Finer finish, slower material removal, better for fine finishing stages, less aggressive on delicate surfaces.

Larger orbit (8mm or more): Faster material removal, better for stripping paint or heavy stock removal, slightly rougher finish that requires finer follow-up passes.

If you often need to remove a lot of material, like stripping paint or heavy sanding, go for the larger orbit. If your work is mostly about finishing, like final sanding or delicate prep, the smaller orbit is better.

Power and Material Removal Speed

Both sanders have brushless electric motors with similar power. In real use, they can handle long sanding sessions without slowing down or overheating, unlike cheaper models.

Material removal speed depends on the orbit, not the motor. For removing paint from car panels, the 5650CV’s larger orbit usually works faster. For fine wood sanding with 220 grit or higher, both sanders perform about the same since orbit size matters less with fine abrasives.

Winner for heavy material removal: 5650CV. Winner for fine finish work: 650CV. Tie on raw motor power: Both.

Ergonomics and Comfort

Both sanders have Mirka’s palm-grip design, low profile, and balanced weight. The center of gravity is close to the pad, which helps reduce wrist exhaustion during long sanding sessions.

Both models weigh about 1 kg. The low profile is more important than the weight for long use, since it means your wrist doesn’t have to work as hard during sanding. Both sanders have textured grips and throttle controls you can adjust with your fingers, so you don’t need to lift the sander to change speed.

Winner: Tie. Ergonomics are essentially identical.

Vibration Dampening

This feature is very important for professionals. Hand-Arm Vibration Syndrome (HAVS) is a real risk from using vibrating tools for long periods, and OSHA rules require tracking vibration exposure in professional shops.

Both the 650CV and 5650CV feature Mirka’s industry-leading low-vibration design. The brushless motor, balanced counterweights, and detailed bearings keep vibration below the levels of nearly every competing electric sander. The myMirka Bluetooth app tracks your vibration exposure as you work, helping you stay within safe daily limits. This is a pro-level feature you won’t find on cheaper sanders.

Winner: Tie. Both sanders lead the industry in vibration performance.

Dust Extraction

Both sanders are made to work with a central vacuum system using standard hose connections. Mirka designs these tools to capture dust right at the source, which is important for:

  • Automotive painters where dust ruins paint jobs
  • Wood finishers where airborne dust lands in wet finish
  • Professional shops where OSHA respirable crystalline silica regulations apply
  • Any shop where operator respiratory health matters

Both sanders have pad hole patterns designed to work with Mirka’s Abranet mesh abrasives. With the right dust extraction, these can remove over 95% of dust right where it’s made.

Winner: Tie. Both use identical dust extraction architecture.

Pad Brake

The pad brake stops the sanding pad quickly when you lift the sander off your work. This prevents the spinning pad from damaging the surface when you put the sander down. Both the 650CV and 5650CV include an electronic pad brake. This is a standard feature across the modern DEROS platform.

Winner: Tie. Both have pad brakes.

Pad Size and Abrasives Compatibility

Both sanders use the standard 6-inch (150mm) pad, which is the most common size for pro refinishing and woodworking. The 6-inch pad covers more area than a 5-inch pad, so you can sand faster over large surfaces.

Both sanders accept the full range of Mirka abrasives, including:

  • Abranet mesh abrasives (best for dust extraction)
  • Autonet mesh abrasives (automotive refinishing)
  • Gold, Polarstar, and other paper-backed abrasives
  • Interface pads for contoured surfaces

One big reason to choose Mirka is their abrasives. They’re pricey, but they last longer and give better results than most other brands.

Winner: Tie. Both use the identical pad size and abrasives.

Bluetooth Connectivity and myMirka App

Both sanders connect to the free myMirka smartphone app via Bluetooth. The app tracks:

  • Daily vibration exposure (HAVS compliance)
  • Total runtime hours (maintenance scheduling)
  • Battery of connected tools (where applicable)
  • Service alerts and firmware updates

For pro shops that need to track worker health, this feature alone can make the Mirka price worth it. With cheaper sanders, you have to track exposure by hand or not at all.

Winner: Tie. Both have identical Bluetooth features.

Voltage Options and Electrical Requirements

Both sanders come in 110V (for North America) and 230V (for Europe and other regions). Make sure you order the right voltage for where you live.

Both sanders work on regular single-phase power, so you don’t need special wiring. A normal 15-amp household or shop circuit is enough.

Winner: Tie.

Price Comparison

As of publication, both the 650CV and 5650CV typically price in the $700 to $900 range, depending on the current promotions, the included accessories, and the dealer.

The difference in price between the two models is typicThe price difference between these two models is usually small, often less than $50. So, price shouldn’t be your main reason for choosing one. Pick the orbit size that fits your work best and get pricing from multiple authorized Mirka dealers before you buy. Beware of unusually low prices on these sanders – counterfeit units exist and lack Mirka’s warranty, abrasive compatibility guarantees, and build quality.

Warranty

Both sanders usually come with a 2-year manufacturer warranty if you buy from an authorized Mirka dealer. Warranty terms can change by region and dealer, so check the details before you buy.

Mirka’s warranty service has a good reputation. Authorized service centers in North America and Europe handle repairs under warranty and usually have reasonable turnaround times.

Important: If you buy a counterfeit or gray-market Mirka sander from an unauthorized seller, you usually won’t get a warranty. The lower price isn’t worth the risk on a tool that costs over $700.

Which Sander Should You Buy?

Buy the Mirka DEROS 5650CV if:

  • Your primary work includes considerable material removal (paint stripping, heavy wood sanding, surface prep)
  • You work in automotive refinishing and body shops.
  • You need the fastest removal rate per sanding session.
  • You do less fine finish work and more aggressive surface preparation.
  • You want the more versatile all-around sander.

Buy the Mirka DEROS 650CV if:

  • Your work is primarily finish-focused (final sanding, between coats, delicate surfaces)
  • You work with fine veneers, high-end woodworking, or delicate antique restoration.
  • Material removal speed matters less than control and finish quality.
  • You already own a more aggressive sander and want a dedicated finishing tool.

Common Buying Mistakes to Avoid

Don’t choose based on price alone. The $20-50 difference between these sanders is small compared to the time or finish quality you could gain by picking the right one. Choose the tool that fits your work, not just the cheaper option.

Don’t ignore voltage requirements. A 230V European sander won’t work on 110V North American power unless you use a transformer, which can lower performance. Always order the right voltage for your area.

Don’t buy from unauthorized dealers. There are fake Mirka sanders out there. If you see a price under $600 for either model, that’s a warning sign. Buy from authorized dealers to get the warranty, abrasive compatibility, and build quality you expect.

Don’t forget to budget for abrasives. Mirka abrasives cost a lot more than generic sandpaper. To get the best results, especially with dust extraction, you need to use Mirka’s own abrasives. Plan to spend $100-300 a year if you’re a pro.

Don’t skip the dust extraction setup. These sanders are made to work with central vacuum systems. If you don’t use proper extraction, you lose a lot of their value and risk your respiratory health.

Frequently Asked Questions

What’s The Main Difference Between The Mirka Deros 650cv And 5650cv?

The main difference is orbit size, which affects material removal speed and finish quality. The larger-orbit model removes material faster and is better for aggressive sanding, while the smaller-orbit model produces a finer finish and is better for finish work. Both share the same pad size (150mm/6 inch), motor type, and ergonomics.

Are The Mirka Deros 650cv And 5650cv Worth The Money?

For professional users, yes. The low vibration, excellent dust extraction, Bluetooth exposure tracking, and build quality justify the premium over cheaper sanders when you use the tool daily. For hobbyists or occasional users, cheaper alternatives provide better value.

Can I Use The Same Abrasives On Both The 650cv And 5650cv?

Yes. Both sanders use the standard 6-inch (150mm) pad size and are compatible with the full range of Mirka abrasives, including Abranet, Autonet, Gold, and Polarstar lines.

Do I Need A Central Vacuum For Mirka Deros Sanders?

Technically, no, but you lose much of the sander’s value without one. The dust extraction architecture is designed to pair with central vacuum systems or portable dust extractors. Without extraction, you breathe more dust, and the sander performs worse.

What’s The Difference Between Mirka Deros And Pneumatic Sanders?

DEROS sanders are electric (corded), while traditional Mirka pneumatic sanders need an air compressor. DEROS eliminates compressor noise, cost, and workspace footprint as delivering comparable performance to pneumatic alternatives.

The Bottom Line

Both the Mirka DEROS 650CV and 5650CV are outstanding professional sanders, though they are expensive. The right choice depends on the kind of work you do most:

If you do a mix of sanding, like automotive work and surface prep, the 5650CV is usually the better buy. Its larger orbit makes aggressive work faster, but it still gives good finish results.

If your main focus is finish work and surface quality matters more than speed, the 650CV is the better choice. Its smaller orbit gives you finer finishes and less extra sanding later.

You can’t go wrong with either one. Both offer great vibration control, dust extraction, and ergonomics, which help justify the higher price for pros.
