The Mirka 9" Dust-Free Basic System (LEROS-S + DEXOS 1230) is a bundled sanding and dust extraction setup built for surface prep on walls and ceilings. This is a dust-free sanding system designed for wall and ceiling sanding. Model number MUSDF-9SBSE30. If you want a matched setup instead of hunting down a compatible sander, extractor, and hose separately, this package gets you into the Mirka system in one shot.

At the center of the kit is the Mirka LEROS-S, a wall and ceiling sander built for broad-area finishing work, paired with the DEXOS 1230 full-capacity dust extractor. That combination matters because overhead and vertical sanding can get messy fast, especially in finished interiors or remodel spaces where dust control is not optional. Pairing the sander with a dedicated extractor helps keep the work area cleaner while supporting a more efficient sanding process.

The 9 inch sanding format is a practical choice for large surface coverage. On walls and ceilings, wider sanding coverage can help you move through patching, skim coat prep, and finishing passes more efficiently than you would with a smaller-format tool. For contractors doing repetitive surface prep, that translates into less time spent working the same square footage.

This system is also about workflow, not just individual components. The included hose with sleeve is there for a reason. On long sanding passes and overhead work, hose management affects how the tool feels and how smoothly you can move. A sleeved hose setup helps keep the line more manageable when you are reaching high or working across a full room.

From a jobsite standpoint, the DEXOS 1230 full-capacity dust extractor gives this system more value than a bare sander package. Dust extraction is a big part of finish quality and cleanup time, especially in drywall repair, repaint prep, and interior remodeling. If your goal is to keep dust down while maintaining steady sanding productivity, a system package like this makes more sense than trying to adapt a wall sander to an unrelated vacuum later.

The Mirka 9" Dust-Free Basic System (LEROS-S + DEXOS 1230) is best suited for drywall finishers, painters, remodelers, and contractors who spend real time on walls and ceilings. It also makes sense for serious users who want a purpose-built Mirka wall sanding system rather than a general-purpose workaround. If your work regularly involves surface prep in occupied homes, finished interiors, or dust-sensitive environments, this is the kind of setup that earns its keep.
