Query: how does this hold up over time?

This seems like a good product in concept, and may be a good product in quality execution... but it's *not*! I have now had three, all three of which have broken, one where the battery electronics/switch failed within one month of (fairly light) use. The other two both broke in less than three months -- both broke off in the handle... completely broken and separated aluminum tube.I am surprised at the quality (lack thereof) for a product so widely advertised.If you're looking to do lots of cleaning and over a long period of time, get a good quality mop, or sponge mop, and a bucket.
