Should I get a vacuum-only model or a vacuum-and-mop combo?

Most strong picks now are combos, but specialist communities consistently caution that robot mopping handles light dust and dried spills, not real wet messes. If you mostly have carpet, a vacuum-focused model like the Shark Matrix is fine; for hard floors that get sticky, a roller-mop combo such as the eufy E25 or C28 earns better marks from testers.
