Version 1.1 in Arknights: Endfield has taken a surprisingly easygoing turn with the Cleanse and Rinse event, live from March 29 to April 19, 2026. If you've spent the past few weeks buried in combat routes, material runs, and map clearing, this mode feels like a proper breather. Some players are already pairing their routine grind with Arknights endfield boosting just to keep pace elsewhere, and that makes this event stand out even more because it asks almost nothing stressful from you. Instead of dodging danger or managing a messy fight, you're walking around Wuling City and cleaning things up. It's simple, a bit silly, and honestly kind of relaxing once you get into it.

How to Unlock It

You won't see the event right away on a fresh account. First, you need to finish Chapter II Process II: Where Danger Sleeps. After that, Wuling City opens properly on the map, and the event becomes available through the Events menu. Hit the prompt, follow the marker, and you're in. That's one of the better parts here. There's no awkward entry cost, no special farming checklist before you start, and no need to build around it. You just unlock the city through normal story progress and go. For players who hate busywork before limited content, that's a nice change.

What You Actually Do

The event itself is built around Auntie Yu, who's overseeing sanitation work in the city. She gives you a set of cleanup jobs that are about as direct as they sound. You wash graffiti off walls, clear away grime from public spots, and spray down Burdenbeasts covered in mud. That's the whole loop. No combat jumps in halfway through, no hidden gotcha. You use the Spray Tool or Drone Jet on marked targets, and the ferrium-treated water is provided for the mission, so you're not burning through your own resources. A lot of players will probably be surprised by how satisfying it is. You point, spray, and watch the mess disappear. It's low stakes, but it works.

Daily Missions and Rewards

At the start, only a small set of tasks is open, including missions like Critter's Trail and Cold Shower. Then more stages unlock day by day in a normal forward schedule, so there's always a reason to check back without feeling overwhelmed. Most of them are quick enough to finish in a short session, which matters if you only log in for a bit after work or class. The rewards aren't throwaway either. You get useful progression materials such as Oroberyl, Marks of Perseverance, and Advanced Cognitive Carriers. There's also an exclusive Expert Cleaner portrait waiting at the end for players who finish the full event line, which gives the whole thing a little extra personality.

Why It Feels Worth Doing

What makes Cleanse and Rinse land so well is the pace. It doesn't try too hard. It gives you a look at Wuling City from a different angle and lets you mess around in the overworld without pressure hanging over every second. That sort of event can do a lot for a game that's usually heavy on systems and tension. Even if you're mainly focused on progression, resource gain, or looking up where to buy Arknights endfield boosting for the more demanding parts of your account, this event still earns a spot in your daily routine because it's quick, useful, and weirdly pleasant to play.
