Ok, so while I love the disposable cleaning pad sensation, they wreak havoc on a budget, so...
I have created my own pads. You can recycle old towels, flannel blankets, even the nice micro fiber towels can be cut to fit the sweeper.
I just made a pattern using a pad so I had the tabs right. I didn't sew a thing, just cut out the pattern & now I can stick them on the sweeper, wet with cleaner, water or nothing & go. When I'm done the rag goes in the wash.
If you don't have any old towels or flannel blankets to recycle try a thrift shop or yard sale, even having to buy your materials would be cheaper in the long run!
