Questions about Bosch Professional GTR 550

The "GTR 550" tool from Bosch Professional is primarily designed for sanding plaster and preparing surfaces for filling and plastering. It is not specifically recommended for removing acrylic paint from concrete walls. This sander is optimised for sanding tasks on plaster surfaces, thanks to its "UltraFlexible Head" which allows smooth movement along walls and ceilings, and is equipped with a ceiling suction system that makes sanding vertical and horizontal surfaces easier. To remove acrylic paint from a concrete wall, you'd probably need a more specialised tool, such as a rotary sander or grinder, which are better suited to this type of task.

The GTR 55-225 is a newer model than the GTR 550 and offers several improvements over the older model. The GTR 55-225 features a patented ultra-flexible sanding head that allows effortless movement over walls and ceilings and reduces the risk of surface damage. The GTR 55-225 is also equipped with an integrated ceiling suction function, which minimises fatigue during longer applications as the perceived tool weight is significantly reduced by the suction force of the resulting vacuum.
