In short, here is my summary feeling. Objectively, after daily use practiced since the return of warm weather, the result is always live up to my expectations. I have about 400-500 m² of surface to be scanned. Ultra efficient for small residues (sand, dust, debris or pine trees, ........) however the most consistent elements (leaves, pine apple, branches ...) you reach too quickly the limit of the product (full recovery tank). In conclusion, prior favorite traditional scan for waste importance, then a passage with the Karcher S650 for finishing. Flawless result. Another advantage: time saving; for comparison, still maintained for the area, a traditional scanning 20-30 min with the Karcher 5/10 minutes.
