So far I’ve had a Roomba, a Eufy and now a Roborock. The Eufy was quiet but was tearing up our trim and furniture so it got retired. The Roomba tore up trim/furniture, was incredibly loud and it was extremely expensive for having no special add-ons. The Roborock is laser guided, clearly mapped our house to gain efficiency, empties itself and is reasonably quiet - cost about $500. Roomba with some of those and arguably lesser features is several hundred dollars more. iRobot is getting the outcome it built for itself.
