I love these
Style: Replacement Pad
These clean the floor well and they are long lasting. So much cheaper than the disposable pads I was using.

Good cleaning action
Style: Replacement Pad
They work well. Big in size. So far have only washed them once and haven’t seen any wear. They wash nicely. And they so far are durable. Great value for your money.
