Super easy to assemble! And even comes with an extra Mop pad that is also machine washable. Just fill it with water, adjust the dial to desired steam output and you’re ready to go! Love that it heats up quickly and cleans/sanitizes my floors perfectly. The triangular head shape allows for cleaning corners well. Mop pad not as thick as expected but works fine. I’m very happy with how easy it is to use. Great product and definitely would recommend!
