Under €300 used to mean dumb bouncing discs; now it includes genuine lidar mapping and even budget self-empty docks. The trade-offs moved to mopping quality and obstacle avoidance. These five maximise different priorities at the price — mapping, quietness, dock convenience — and we're explicit about what each one gives up.

Buying guide: how to choose
Lidar navigation is the dividing line
Sub-€200 robots mostly bounce randomly; lidar models map rooms, clean in neat rows, and let you say 'kitchen only' from the app. If the budget reaches €250, cross the lidar line — it's the single biggest experience upgrade.
Suction numbers (Pa) are half-truths
Manufacturers quote Pascals (5,000–18,000 Pa), but brush design and airflow matter as much. Carpet homes need 5,000 Pa+; hard floors are easy for anything decent. Treat Pa as a tiebreaker, not a ranking.
Self-empty docks change the relationship
Without one, you empty a tiny bin every run or two. With one, the robot empties itself for 4–8 weeks. For pet homes or busy households, the dock converts a gadget into an appliance. Budget €100–200 extra; worth it.
Mopping: pads wipe, systems wash
Basic drag-a-damp-pad mopping freshens hard floors. Real mopping systems (rotating pads, self-washing docks) handle actual dirt. Irish homes with tiled kitchens and hallways get real value from the better systems — muddy paw season is long.
Frequently asked questions
Are robot vacuums worth it?
If floors are your recurring chore, yes — the daily maintenance clean they provide keeps homes visibly tidier between deep cleans. They don't replace an upright for stairs and corners; they replace the need to do floors every day or two.
Will it fall down my stairs?
No — cliff sensors are universal and reliable on standard stairs. The real edge cases are dark/black floor borders (some sensors read them as cliffs and refuse) and very low thresholds. Multi-storey homes simply carry the robot between floors; maps for each floor are standard on lidar models.
Do robot vacuums work on carpet?
Modern mid-range and up handle low and medium pile well — look for 5,000 Pa+ and active carpet boost. Deep-pile rugs and dark carpets (which confuse some cliff sensors) remain the awkward cases. Mixed Irish homes with rugs: choose models with auto mop-lifting.
