So far so good... time will tell on longevity. I use this in my home and it really works well. I think the heated water system is a big help. I love this product; however, I am also mechanically inclined. I think there are some mechanically challenged people who may have difficulty with the cleaning process, as it involves removing screws and dismantling parts. This machine doesn't hold a lot of water but unless your carpets are filthy, there is no need to use much water, which means the carpets dry quickly as well - normally overnight.
