The EXO-200 experiment is searching for neutrinoless double beta decay using a time projection chamber filled with liquid xenon enriched in Xe-136. The detector has demonstrated exceptional performance with world leading measurements and stringent search results. The detector finished its Phase-I running shortly after an unexpected interruption in operations caused by incidents at the Waste Isolation Pilot Plant, but has restarted in Phase-II with hardware upgrades. During the two-year hiatus, the EXO-200 collaboration published several results using data from Phase-I. This article reports on the recent results and status of this detector, as well as on the proposed nEXO detector, the next generation experiment rooted in the success of EXO-200.
