Which fits which window

Both rows are window cleaning robots. Published specification coverage is thin for at least one of the two rows this build, so this comparison deliberately stops at recorded facts: subtype, surface focus from the campaign records, and the dated campaign terms above. Where a specification is not published by the manufacturer, we say so rather than filling it with a zero or a guess. Check each product page's campaign record for window dates before relying on any deal code.
