Solidly built piece of kit and does the job very well. There is a tendency for the hose outlet to clog with any large bits of waste so you need to check this is clear before each cut. So long as this is done, it is quite clean working.
I bought this machine to chase the wall out for hot and cold pipes for a mixer tap shower, the machine worked well and did the job, I used a Merka vacuum machine designed for this sort of work but I still got a fare amount of dust .
Overall it's a good machine for the price.
