Current fit-check result: Start with the first hard constraint.
CONSTRAINT FIT CHECKERNo result yetStart with the first hard constraint.
Answer whether travel, shower use, or disappearing sink storage makes cordless non-negotiable. That one answer removes more false clicks than feature-count shopping.
If cordless is mandatory, only the WP-580 stays in the running. If it is not, the stronger countertop paths remain available.
