In an earlier post, I mentioned that after using this unit, an automatic system that would pump the (filtered) water back into the cleaning reservoir is a feature I'd be willing to pay more for, but I certainly don't fault the designers for this cost-saving feature as it is in the Humminguru. Also, I've never had the lid come off while pouring the water back into the unit, though I agree it would be nice if there weren't any drips out the corners, AND I can't imagine those few drops of unfiltered water will make any difference in the cleaning process (so I agree with you that it isn't a huge deal). And wasn't it the case that from the start, the designers of this cleaner planned for a new tank of water for each cleaning? I seem to recall that the idea of re-using the water was something that evolved during the design/testing/feedback stages of the process. So again (if this is true), I can't find fault with the current design even if I can envision that it could be improved upon (a gasket around the lid of the water tank should solve the dripping problem, for example).
