So I have a space in a basement that just had some construction done and dust has been sitting for weeks. I swept a couple times and mopped up the floors to get rid of some of the dust, it looks like it did was spread the dust around despite the bucket being almost black when cleaning it. I tried using a handheld brush to brush the dust off as well but it also looks like it’s just spreading it. Is there anything I can use to most easily clean these floors?

Here is a picture of the floors after sweeping and mopping: https://imgur.com/a/g0FwoA9

Thanks.
