The PLANEX M offers a basic easy-to-use interface with a refined sanding pattern utilizing random orbit motion. Simply unpack the sander from the carry bag, turn it on and get to work. The random orbit sanding motion achieves a high surface quality on walls and ceilings. The adjustable suction power means that you can sand on walls and ceilings with less fatigue – helping to reduce the strain on your arms and back. Its working length of 55" (1.4 meters) is ideal for all standard room heights. And with the ergonomic T-handle, the machine is highly controllable and comfortable while also being able to reach most commonly needed surface heights.
