I had a 10 m3 tank cleaning and the bottom was filled with 30 cm of slush consisting of everything you can imagine worse after a reflux coming from the sewers. Thanks to this aspi and its extension 3m I could relatively quickly empty the smelly mud. Reverse tunnel also allowed me to break down said vessel before it. The opening system is practical and well thought out, it can fill the tank and then empty it once it is full in the manner of a bucket. permetten wheels moving the aspi strong quickly. There is obviously a lot of noise but aspier water and mud it takes the power and there aa spare. Although happy with my purchase, which saved me over 50 euros on prices in my area
