Installed new bumper absorbers (white) on the Roomba the other day. Just noticed that it's cleaning now and I can't hear it bump into anything like it did before.
I've had it for at least 10 years now...it's been excellent.
Other installed improvements....
extended life battery
hd brushes, rollers, and carriage
upgraded dust bin with motor.
parts upgrades is as fun as with a car.
Anyone else have one that old..or older?
