Grills and toilet bowls are where people reach for the harshest bottles, and both sit where residue matters. The rubric here: mechanical scrubbing instead of solvents, water only operation, no fumes in a closed bathroom, and brush heads you can replace as they wear. Each option below meets at least one of these.

Nobody wants to kneel at a toilet bowl or scrape a cold grill grate, so both jobs get postponed. What matters for hands off work: an automatic cycle you can start and leave, self contained power, and a fit that stays put on its own. The picks below each cover one or more fronts.
