This wall here processing system is perhaps precisely tailored to walls, but certainly also for floors and partly used for ceilings.
Supplied the system with three different grinding wheels, a grinding plate, a perforator and a plastic brush. The manual in many languages is clear and very well illustrated. To start only the two parts with the plastic tube connected to an attachment and are plugged and away you go. When attaching the hose, I was a little disappointed, because here is the complete plastic construction, what I would have wished otherwise in the equipment price.
What stands out is next to the heavy weight. Despite the high plastic content, the weight is quite high and not easy to use when working for extended periods. I had after the first day already sore muscles, but otherwise have a very different frame of movement as not craftsmen which certainly plays a role.
Due to the size of the device will not get you into corners or tight turns, here then you have yet again help the good old putty.
Operation and handling are relatively simple and the unit is operating effectively and rapidly, especially in larger areas. The dust is extracted to a large extent, of course, not completely. To this end, I would advise on any case to a mouthguard. Not to be forgotten is the filter that needs to be cleaned every now and again, thereby the suction power once again higher. Also, the device is not really quiet, but not extremely loud, a hearing protection yet no harm.
Conclusion: Easy to use and great effect, if not the great weight and the many plastic connectors would be, I would forgive a full five stars, for that price I expect nevertheless a little more stability, thus four star.
