In my opinion, the iRobot support and parts availability are worth the premium. Our 2013 model 650 is still running great. All we’ve had to do is periodically replace worn out brushes and spinners and at some point we replaced the main battery. This is all easily done with a screwdriver.

Totally agree. I just checked my order history: I bought my current Roomba 650 in May 2014, so it's been running 4-5 days a week for almost 6 years straight with various simple part replacements. Really great little product, and excellent customer support and user community.

At one point the tread wore out on the wheels, so it was struggling to get over the threshold into different rooms. Rather than buy a whole new set of wheels, I found a blog saying that Kirby 301291 vacuum cleaner belts just happen to perfectly fit on roomba wheels and work as replacement treads. Now it's been happily rolling around on vacuum belts for the past year or more.

I absolutely agree. I got a broken 650 from my sister, fixed it with a cheap easily available part, and it has worked beautifully for the last three years.

It is also a joy to maintain and was obviously designed by people who care about maintenance being reasonable.

Same here with a 650 I got in 2016. It runs daily, and all I've ever had to do with it is replace the brushes/spinners twice.
