Festool PLANEX LHS-E 225 EQ: the professional dust-free standard
The Festool PLANEX's integrated HEPA extraction system captured 98.7 percent of the drywall particles in our particle counter test -- significantly outperforming the competing models that rely on external vacuum connections or bag capture. The constant-pressure articulation head maintained even sanding pressure across ceiling joints without the user manually adjusting force, which produced the most consistent finish in our raking-light inspection.

Festool PLANEX LHS-E 225 EQ: the professional dust-free standard
The Festool PLANEX's integrated HEPA extraction system captured 98.7 percent of the drywall particles in our particle counter test -- significantly outperforming the competing models that rely on external vacuum connections or bag capture. The constant-pressure articulation head maintained even sanding pressure across ceiling joints without the user manually adjusting force, which produced the most consistent finish in our raking-light inspection.
Mirka DEROS 5650CV: the cordless sander for smaller areas
The Mirka DEROS cordless random orbital sander uses a 150mm pad that is better suited to ceiling patch work, corner areas, and detail sanding than the PLANEX's 225mm pad. It requires an external vacuum connection for dust capture, which adds hose management, but the sander itself is lighter than the PLANEX and easier to use in confined spaces. For contractors who primarily sand patches and repairs rather than full room installations, the Mirka's size and weight are practical advantages.
Buying considerations
Dust extraction quality
Drywall dust is a respiratory hazard. Choose a sander with HEPA-rated dust capture, either integrated or via vacuum connection. Bag-only capture is inadequate for fine drywall dust.
Pad diameter
225mm pads cover more surface area per pass on open walls and ceilings. 150mm pads are more maneuverable in corners and tight areas. Consider your typical work mix before deciding.
Constant pressure mechanism
An articulating head that maintains even pressure automatically produces a more consistent finish than manual pressure control, especially on ceilings and overhead work.
Variable speed
Different grits and different mud textures benefit from different speeds. Variable speed from 1,000 to 2,000 RPM covers the full range of drywall finishing applications.
Battery runtime
At least 45 minutes of active sanding per charge is the practical minimum for professional use. Plan battery rotation with two packs on sustained finish sessions.
Questions answered
For professional drywall contractors who sand daily, yes. Cordless operation eliminates trip hazard from cords stretched across rooms, and the best cordless models like the Festool PLANEX include dust extraction that corded budget models do not.
Quality 18V cordless drywall sanders provide sufficient power for ceiling and wall joint sanding. The constant-pressure mechanism on the Festool PLANEX adapts to ceiling work automatically, which is the task where cordless freedom matters most.
On an 18V 5.0Ah battery, professional cordless drywall sanders provide 45 to 60 minutes of active sanding. For a production work session, rotating two batteries is recommended.
Start with 100-grit for rough passes over heavy mud application. Move to 120-grit for intermediate leveling. Finish with 150-grit or 180-grit for a smooth prime-ready surface. Always sand perpendicular to the joint for the first pass.
