Mirka PROS 6-in. Pneumatic Random Orbital Sander with 8mm Orbit and Central Vacuum (MRP-680CV)

Mirka PROS Pneumatic Central Vacuum 6 Inch 8mm Orbital Sander, model MRP-680CV, is a professional pneumatic random orbital sander built for fast finishing and material removal on larger surfaces. This is a pneumatic random orbital sander designed for aggressive sanding and finishing operations where dust control matters. If you want a 6 inch air sander that can move quickly without giving up control, this is the one Mirka aimed at serious shop and jobsite users.

The big reason to choose this version is the 8 mm orbit. That larger orbit is better for rapid stock removal and heavy-duty finishing work than a smaller finishing-focused orbit. In practical terms, that means you can level filler, flatten panels, and move through prep work faster before stepping down through finer abrasives. The 6 inch pad also makes sense for covering more area per pass, so it is well suited to doors, panels, tabletops, and other broad surfaces.

Mirka built the PROS platform around comfort and control. The housing is shaped for a secure grip, and the tool is designed to stay user-friendly during longer operating periods. That matters with an air sander because the tool only helps if you can keep it steady and consistent over a full shift. At 3.65 lbs, it has enough presence to feel planted without becoming overly bulky for overhead or extended sanding work.

Dust extraction is a real selling point here, not a throwaway spec. The central vacuum setup, quick-connect fitting for the dust extraction hose, and Mirka shroud system with brake seal are designed to minimize internal air leakage. The benefit is better dust pickup, including when suction power is lower than ideal. Cleaner extraction helps keep abrasives cutting more consistently, reduces cleanup, and makes it easier to see the surface as you work.

This Mirka sander is a strong fit for users already set up with a central vacuum sanding system and 6 inch sanding workflows. It is meant for shops and pros who value extraction, finish consistency, and speed. If you are sanding larger surfaces and want a pneumatic orbital sander that is comfortable to run for extended periods, the MRP-680CV hits a very practical middle ground between aggressive cut and day-to-day control.

Who should buy it? Woodworkers, finish carpenters, remodelers, and anyone doing repeated surface prep on wood, composites, or similar materials will get the most out of it. It is especially useful when the goal is to remove material quickly while keeping dust under control. If your workflow depends on a compact air-powered sander rather than a cordless or corded electric unit, this Mirka random orbital sander is built for that environment.
