I love my Swiffer WetJet and have used it for a couple of years now. Unfortunately, like all of these types of products, I need to purchase refills on the solution and the mop pads.
Once I ran out of the solution though, I began filling it with my own homemade solutions. I have done every type of solution known to man. I have filled it with a mixture of hardwood floor cleaner with water, a vinegar & water solution, and other floor cleaners in our cabinets. They all worked wonderfully and cost us a fraction of the cost. As a disclaimer though, the company suggests that you use only their cleaners, otherwise you risk clogging the unit and they will not warranty the product anymore.
I also did not want to pay for the pads, as they too cost quite a bit of money for something you just throw away. I tried using microfiber cloths, but they wouldn’t hang onto the mop head well. I then tried just using the regular pads (as they cost a little less) and ended up with a soaking mess.
The solution that I found works better than anything I have ever tried and I promise you, if you buy these, you will never have to buy the disposable stuff again. These terry mop heads fit my Bissell Steam Mop (which they no longer sell) and they fit on the Swiffer WetJet PERFECTLY!. They have a little adjuster on it that can help you hug the mop head tighter and they do not come off. They are made out of terry cloth and when you are done with them, just throw them in the wash with your towels. I had bought several packages, for fear that they would discontinue selling these like they did my steamer, and I absolutely love them. This is a great reusable solution that will cost you much less in the long run. You receive two mop heads in a package and they are currently listed at $9.70.
Product endorsement over- hope you can try these! You won’t be disappointed!
