Irobot Informative - Roomba Scheduler
My family has had a Roomba Discovery since Christmas 2003, and it's served us pretty well in that time. At first, we considered it like a toy or some entertainment, then we were surprised at the job it did. It doesn't replace heavy-duty vacuuming if there's a giant mess, but if you run it often enough there's not much of a chance that a mess will get very bad.
That's also what's so good about our new Roomba Scheduler. Instead of pushing a button to make it work, we can program it to make it work. The difference is we don't have to be there now. Instead of running it at night and having to listen to it whir around and bounce into walls and furniture, now we've got it programmed to run at one in the afternoon, when my wife and I are at work and the kids are usually at school. So it wakes up and vacuums and goes back to sleep in its charger, all while we're not there.
Yeah, it is a bit on the expensive side of the Roomba line (about $325), but if you've already got one, then why not upgrade to the best available? That's what we did, and I think it's worth it since we don't even have to think about vacuuming any more.
