I bought sawdust from chipboard with a bang for work on installing kitchens, but he doesn’t like the dust from drilling the walls) now my wife is at home and she doesn’t give it to me, she really liked it) I’ll have to buy a second one. Got pros: mobile excellent suction conveniently made floor nozzle is very manoeuvrable duration of work With its cons: instantly clogged with fine dust, but most likely it is not intended for this. button must be held. the emptying of the garbage collection tank is not very convenient, firstly the sand is clogged into the grooves and secondly when you put the tube and the tank with the pipe is spinning) but these are trifles.
