Brondell GoSpa Collapsible vs TOTO Travel Handy Washlet YEW350

Two kinds of device at a similar size: the Brondell GoSpa Collapsible is a squeeze bottle, the TOTO Travel Handy Washlet YEW350 a electric handheld. Close enough to carry that the mechanism is the real choice. The table compares only what each manufacturer actually publishes. Blank cells are unpublished figures, not zeroes.

One of these two publishes very little. Most rows below will be blank on one side, which tells you about the manufacturer rather than about the product.
