Roomba

Quite a few years ago Robbie and I got Grandma a Roomba vacuum like mine for Christmas.  It has worked wonderfully until about six months or so ago.  She brought it down for Robbie to look at; upon contacting Roomba they said, "sorry, it's old, warranty is up, but we will give you a credit toward a new machine".

and that was nice.  However, Rob does not give up that easily.  He did mass internet research, ordered a two tiny little new infra-red sensor chips, took the Roomba completely apart, sautered in the new chips and...voila.  Now works wonderfully.  After that he did a hard reset on the battery and I kid you not, the thing works like NEW.  To say that least, I am IMPRESSED.  Good job babe!

                     This is a pic of one of the sensors.  The sensors he replaced were about half this size!
