1. How does Roomba choose its speed?
2. Why is my Roomba moving slowly even if no obstacles are in proximity?
Thanks in advance. And sorry my English.

I routinely clean my 550 with a hand vacuum cleaner and a small brush. These procedure takes few time and maintains sensors reasonably OK. Roomba seems happy and runs like a champ!

Roomba does slow down before buming into walls.
