Our black slate kitchen floor leads out onto a black slate patio. I was giving the kitchen floor a quick vacuum and looked outside and thought the patio could do with a sweep too. I hate sweeping the patio, it's basically brushing debris from one side to the other. I then had a genius (???) idea - vacuum the patio!! So I did. Obviously it was bone dry out there. It worked a treat; why wouldn't it. I'm never going to sweep the patio again! 🧹 🧹
