This sucker, however, convinced so far very good performance and at least so far, steady battery, which is also quickly recharged. The workmanship is very good, unclean crafted edges or similar I could not discover. Another practical feature is the operator - pressing briefly once the start button, and it will run until you press the button again. This simplifies handling. Of course he does not have the power of a 2,000-W canister vacuum cleaner, but he's not even designed for large areas, but for smaller spills. The volume I find acceptable.
