Solid waste removal: A high score means the toilet effectively and consistently evacuates various types of solid waste from the bowl through the trapway and into the drainage system. A top-scoring model delivers a strong flush that helps prevent clogs and reduces the need to plunge.

Noise: Flush quietness without the seat.

Bowl cleaning: A high score means the toilet flushes away more waste from the inner surface of the toilet bowl, particularly the front and side walls where residue is most likely to remain. A top-scoring model stays cleaner with less scrubbing.
