You may remember how much I adore our Roomba. Turns out one of their biggest flaws is that the batteries kick out after about a year of regular use. They do better with more regular use but we use ours only 2 or 3 times per week so maybe not enough to cycle the battery enough. Where we previously got an hour of cleaning out of it, we were now getting only about 15 minutes at most - barely enough to cover the kitchen. Argh.

Some day.
