The small text in the ad says the lint goes down the drain. I knew a family that had one of these in Woodtone Brown. It was very quiet. Mostly what you heard while it was running was the water running, like a toilet was filling somewhere in the house. The water shut off a few minutes before the motor stopped. The lady had a waterfall front Kenmore washer and set the timer to 60 minutes to dry everything in a mixed cottons load.
Do you see that little plastic box near the top of the inner door? Fuzz used to collect on it, but not much. It held the air freshener tablet. Hotpoint advertised that their "high density" Calrod elements did not glow red in their water dryers, meaning, I guess, that the heat was not as intense.
