My Logitech MX ergo doesn’t need a lot of cleaning. Once in a while maybe. But it is designed in a way that the dirt comes out at the bottom by itself. There are also no wheels, it uses optical detection of movement, like an optical mouse. Once in a while a hair or some dust gets stuck in front oft the sensor. Then you need to clean it. But this happens maybe twice a year for me.
