Can you believe it is my 1st time come across floor curling. So for the 1st photo i thought it is some new way to clean our floor. One look like some kind of sweeper. Another like the floor vacuum robot. haha.
Anyway, hope your bruise and muscle will get better in no time so can go sport again gaogao.
Hahaha! Yup, I feel fine now that my legs have been returned to me ....looking forwards to our next session. Fyi, we use the sweeper or brush as it is called, to sweep the ice, so you are right ! The 'robot' is the stone.
