r/eufy

A few weeks ago, I posted here about my brand-new Eufy Omni S2 making an insanely loud whistle during mop washing:

Eufy Omni S2 – extremely loud high-pitched whistling noise during mop washing

Here’s the ending to that story, because somehow Anker managed to make it even more ridiculous.

I sent Anker a video of the whistle right at the beginning.

Their first answer:

“Within product specifications.”

I didn’t buy that, especially because Eufy’s own global troubleshooting page specifically mentions a “high-pitched whistling sound” during mop washing/wastewater draining and says it can be caused by vibration of a duckbill valve in the dirty-water system.

So I tried Eufy’s recommended adjustment.

No change whatsoever. Still WHISTLEEEEEEEEE.

I contacted Anker again. They sent my video to their headquarters for further review.

Headquarters came back with:

“Normal operating sound during water intake.”

Apparently my ¥200,000 flagship robot vacuum had simply decided that mop washing should include a free musical performance.

Meanwhile, another S2 owner in my original thread was kind enough to record his own mop-washing cycle for comparison.

His S2?

No whistle.

After more back-and-forth, something interesting happened.

Anker’s position changed from “normal operating sound” to “the product is likely to have a fault.”

They collected the entire S2 and base station.

Then I waited.

And waited.

For about two weeks I had no S2 and essentially no useful status information.

Then a large package unexpectedly arrived.

I opened it.

Brand-new S2.

Not my repaired unit. A completely new one.

Naturally, there was only one thing I cared about.

I charged it, started the same mop-washing operation, and waited for the supposedly “normal” whistle.

...

Nothing.

Absolutely nothing.

No whistle.

Not a quieter whistle.

Not an improved whistle.

Not a whistle that became acceptable after some adjustment.

There is no fucking whistle.

So, just to recap:

Brand-new S2 #1: WHISTLEEEEEEEEE
Me: This seems wrong.
Anker: Within specifications.
Me: Here’s your own documentation about this exact kind of whistle.
Anker HQ: Normal operating sound.
Other S2 owner: Mine doesn’t do that.
Anker later: Actually, yours is likely faulty.
Anker: takes the whole machine away
Two weeks later: Brand-new S2 #2 appears.
Brand-new S2 #2: ...

Silence.

So yes, I eventually got a working replacement.

But I started this adventure with a brand-new S2, spent weeks convincing Anker that my brand-new S2 had a problem, went without the machine while they dealt with it, and eventually received...

a brand-new S2.

Incredible upgrade.

I didn’t need compensation. I didn’t need an upgrade. I didn’t need weeks of troubleshooting and arguments over whether an ear-piercing whistle was somehow a feature.

I just needed the brand-new machine I paid for to work like a normal one.

And apparently that took a month.

Hello everyone,

On the day of the update, our doorbell rang by itself. After checking the cameras, no one rang.

We took the opportunity to recharge it, and before putting it back, out of curiosity, I tried pressing it, but it no longer rang on the Homebase.

The camera works on the app, but not the doorbell. Even trying to reset the ringtone on the Homebase in the app didn't work.

So I had the idea to remove it from the app and add it again, but now I can't add it.

At the step where you have to press the Sync button on the back, there should normally be one beep, but it doesn't do anything. I tried pressing and holding Sync to reset it, but still nothing happens.

Is it broken? It worked perfectly before this update 🫤

I bought one and its wifi is faulty. eufy told me it's also been discontinued and to get a replacement or refund.

I heard that the eufy Pet app is no longer supported, and to use the Anker eufy app. Does it still function the same? Has this camera held up for others?

My other option is a Furbo, but I am turned off by the subscription model.

I have been annoyed for quite awhile at the slow, even intermittent, camera display. I blamed the app. Finally got around to reorganising the top shelf of the cupboard which also houses our Internet Router. They now have almost a metre of separation. Viewing camera events is noticeably quicker. Well worth doing.
