leinhos's Journal: Roomba's little helper gets new batteries

My oldest daughter calls the Roomba's virtual wall unit "Roomba's little helper". When we run our Roomba at night, I always tell her "don't forget Roomba's little helper," and she goes to turn on the virtual wall unit to keep the thing from getting stuck on the threshold between our front hall and kitchen (iRobot says it should be able to clear the threshold, but it *always* seems to get stuck trying to traverse the threshold at an angle).

We've been running our roomba (almost) every night for the past 8 months, and finally need to change the 2 D-cell batteries.

The Roomba battery pack itself is now starting to show signs of age, after an estimated 200+ hours of operation (and at least that many recharge cycles).
