Not bad but not a groundbreaking innovation

I vacillate back and forth, if the broom is worth a recommendation. Basically, he is very well made. The telescopic handle, the variable height adjustment, the coupling on the stem end and the broom itself are of high quality materials and durable effect. Conveniently, you can use various attachments. For example, there a window wiper and a floor scrubber using the same plug-in system. Only the actual innovation, the curved broom, I can not quite clear. Where should be the advantage? One can, for example, poor return in the forward movement and also in the corners does it significantly more difficult. So better buy a classic broom!
