So far so good!
I was looking for a metal design like this. I had another sponge mop with rollers but the casing that held the rollers was plastic and it broke within a year. I've seen a few reviews of the Bee Mop sponge, where people have said the sponge comes apart from the bracket, but so far mine shows no signs of wear. The sponge is very porous and it's different from most synthetic sponges, but it works well. Molto bene!
I got tired of using spray mops that mostly just move the dirt around on the floor. I decided on this mop and I'm glad I did. It works great. You can actually put some elbow grease into moping and get the dirt up instead of watering it down and most of it staying on the floor. It even cleans the shoe molding on the base boards, which I always had to go back and clean by hand. I do wish it had a way to wring the water out without using your hands, but otherwise, it great. It is effective, sturdy and easy to use.
