Wide Application: This versatile drywall sander is suitable for lime walls and putty surfaces, ideal for DIY home projects, professional renovations, and construction work. (For old popcorn ceilings, you must first use a handheld electric trowel polishing machine to smooth out the bumps, then use our drywall sander to sand it flat.) Powerful Brush Motor: 900w suction power with the self-suction function makes for efficient dust and debris collection while in use. It is equipped with a constant power board, and added overload protection, resulting in a longer, more stable, and more efficient lifespan than ordinary motors. 800-1800rpm stepless speed adjustment allows for easy sanding even on tougher surfaces such as wooden floors. Optimized Ducts for Less Dust : 3 suction ports with a 3-fold increase in suction ducts result in a 50% improvement in dust collection efficiency. It comes with a hose and suction tube and is compatible with most vacuum cleaners on the market. The vacuum suction system can absorb 90% of dust, creating a healthier sanding environment. All For Your Convenience: Weighing only 3.5KG, and greatly reducing labor intensity. 3:7 optimal weight distribution ratio effectively avoids imbalance. Lightweight and extendable pole allows for effortless sanding even in hard-to-reach areas. Double-layer LED strip provides full coverage lighting to ensure a clear view. And the foldable design makes it easy to store and carry. Abundant Accessories:Our electric drywall sander includes a 215mm large sanding pad for efficient sanding, and a 360-degree surround brush to prevent dust from flying around.
