During the event, you can log into Genshin Impact daily, claim Commission Rewards, open treasure chests, and complete other challenge missions to obtain Stamina.
Stamina can be used to unlock Cleanup Commission stages during the event. Complete stages to obtain Primogem rewards as well as the event item "Wastewater."
The event item "Wastewater" can be exchanged for Cleanup Reputation. Once your Cleanup Reputation reaches a certain amount, you can obtain Primogems, Mystic Enhancement Ore, Hero's Wit, and other rewards.
* For players on some servers, when Daily Missions begin at 04:00 (Server Time) on the first day, rewards for inviting returning players will also be made available for claiming.
==Cleanup Commissions==
# Log in to the web event and Genshin Impact daily, and carry out other actions to obtain Stamina.
# Daily missions refresh at 04:00 (Server Time) each day. Unclaimed Stamina will also be cleared by then. Please claim and use the Stamina in time.
# During the event period, Travelers can obtain Stamina by doing things like opening treasure chests while exploring the map, enhancing Artifacts, and defeating powerful opponents a certain number of times.
# The challenge missions will not refresh daily, and you can obtain a maximum of 250 Stamina by completing them. Completed missions will not award Stamina beyond this limit.
# Stamina will not be cleared once you have claimed it.
# You can spend Stamina to unlock different stages. There are a total of 6 Cleanup Commission stages in the event. The first time you complete a stage, you'll obtain the event item "Wastewater" as well as Primogems, Mystic Enhancement Ore, Hero's Wit, and other rewards.
# Before completing all stages, each stage can be replayed without spending Stamina (but no additional rewards will be obtained). After completing all stages, you can replay Stage 6 "A Classic Play" to obtain extra Wastewater.
