Combo vac-mop robots vs separate vac and mop: Combo saves time on hard floors, separates clean better

Combo robots handle both jobs in one pass, saving time on hard floors, but vacuum-only bots have better suction and longer battery life. Combos cost more and their mopping is just a light damp wipe, not a deep scrub. Go combo if you have mostly hard floors and hate manual mopping; choose separates for carpet or max performance.
