Do countertop and portable dishwashers actually clean well?

For light, daily loads the consensus is cautiously positive. A high-trust testing writeup found the COMFEE' countertop unit delivered clean, dry dishes (at roughly a 130-minute cycle), and community reviewers in tiny-home and apartment threads echo that it handles 2-3 people's dishes well. The recurring limitation reviewers flag is capacity and cycle length: they are not built for big family dinners, pots, or pans.
