Will buy again
Style: Steam Mop
I’m pretty impressed with this steam mop. It cleans great, leaving no streaks. It’s easy to handle with its decent sized griped handle. It’s durable and easy to use. It’s sleek and lightweight with a pretty long cord. I highly recommend.

Needs a longer cord! But does the job well!
Style: Steam Mop
My only complaint is the cord is not long enough! I have to go around finding every outlet to plug it into to get my whole house clean.

You get what you pay for
Style: Steam Mop
It's just OK. It does get the job done, but poorly made and I don't expect it to last long. Unlike other steam mops I've had, this one leaves the floor wet. Plus the pad does not pick up any stuck-on gunk that the steam loosened. I had to go back and pick up a few pieces by hand. Instructions say to let the water tank air dry before storing, but the attached lid makes it hard to let air into the tank. In retrospect I should have spent a few dollars more and gotten a better unit.

Good purchase for the price point
Style: Steam Mop
This mop is perfect as it is compact while being easy to use. Stuck food on the floor? Not after using this. Crayon? Vanishes. Sticky substance? no more. Great but for the price
