I found no authority that sizes robots by floor area, and rated runtimes can run well ahead of what reviewers saw. I'd start with the Eufy Omni E25 for a mid-size home and treat large-home claims with care.

Start with what your kitchen allows: a stretch of counter by the sink, an 18-inch gap or a 24-inch gap. I'd pick the Danby for renters and the Bosch for a tight built-in.

Energy Star puts a very damp basement under 2,000 sq ft (186 m²) at 25 to 40 pints a day, and says to oversize. The bigger question is where the water goes, so I'd check for a floor drain first.

AHAM's two-thirds rule sorts these five purifiers from a small bedroom to about 680 sq ft (63 m²). I'd start with the Blueair 311i Max and move up only if your tape measure says so.

For a small household I'd buy a plain drawer fryer before anything clever, because Tom's Guide's top pick crisped fries in under 10 minutes. The glass Crispi and a countertop oven only win in narrower cases.
