Mosaic stone pavement ...

We have the sweeper with a queasy feeling of purchases because we do not have many smooth surfaces such as asphalt or the like. Instead, is with us a mosaic pavement with partly deeper joints. There, of course, very easily collects any dirt, stones, or other. However, after the initial trials has shown that the purchase was worthwhile because it works pretty well. While there are areas, as you have often sweep over it, but the patch is super swept, despite stones and dirt in the joints, this is as it should, transported in the hopper. Would we buy it again.
