Very good vacuum cleaner at a reasonable price. Was used in a new building and really swallows everything. Has not made limp even when concrete residues or greater screed crumbs after chiselling. For sanding dust from filling work often times simply blow out the filter when the suction performance drops. Small drawback: The suction tube is relatively soft and therefore bends in advance (therefore less deductions). But with the price ok and therefore strong buy recommendation.
