Great idea, bad execution. Mine started rusting after 90 days (see images) – (30/10) – Roborock published a fake review count and rating from this website on their Dyad page (https://roborock.com.au/products/roborock-dyad). On 16/09/2022, the Roborock website falsified that there hundreds of reviews (as of today, there are 15), as well as a more positive rating than this website showed. ProductReview were notified and Roborock's website now shows the actual live widget with the correct information.

-- UPDATE 3 (27/10/2022) [TL;DR] Roborock requested to be sent my Dyad from the Service Centre. I do not know where it is and they will not provide me with a tracking number. They have gone silent and I can't get in touch. They owe me $799 and are ghosting me. Do not buy this product, fair reader.] --

ORIGINAL

TL;DR: I've had my dyad for 4 months and all of the metal parts I can see on the exterior are rusting (including the charging contacts). I dread to think of the state of the internals. Roborock have said this isn't an issue - which is obviously not accurate. They offered to "repair" it, but only if there is no water damage. How is it possible that a device like this will not have been in contact with water?

I purchased my Dyad on 22/04/2022 from the offical Roborock Australia website. Initially, the product was excellent and I couldn't believe no one had through of this design or approach before.

After about 90 days of weekly / bi-weekly usage, I noticed the screws below the clean water tank (the one up top) were rusting. See image 1. I contacted Roborock about this and their response was:

"I just consulted the seniors with the provided picture. The current state of the screws will not affect the normal use of the machine, pls don't worry. Pls don't use the third-party cleaner solution in the future in case of deepening the corrosion."

I wasn't happy with this response (especially since I had not used any third-party cleaners), because as we all know, rusting is a process that will continue until eventually the metal part is corroded to the extent that it won't function.

It was during this correspondence that I noticed that all of the other exposed metal parts were also rusting. This includes the screws in the dirty water tank (image 2), the small clip which holds the front roller in place during use (image 3), and even the charging contacts on the dock (image 4). This last one is actually stopping it from charging. It is also giving me Error 3 (water tank empty) randomly when the tank is full.

I've sent this information to Roborock, who are about to send me a return shipping label so that they can inspect the device. They've cautioned me that if there is liquid damage, then it is not covered by warranty. Now, this last point is ludicrous. Here, we have a product which advertises that it INHERENTLY deals with liquids. It contains not 1, but 2 water tanks, and advertises its ability to clean wet and dry messes. We have metal parts, which BY THE VERY DESIGN of the product will come into contact with water. How is it possible that warranty can be denied?

I will update here as I go through this process with Roborock.

One other thought as to the product as a concept: It bills itself as being self cleaning, and mostly, this is accurate. However, in reality, you would only use this product once or twice per week. In that time, mildew and bacteria have built up on the rollers. So yes, it does self-clean after you've finished cleaning, but since it doesn't dry the rollers, what's the point? If you wait a week then clean again without taking them off and cleaning / drying them yourself, your whole house smells like mildew. It needs a drying function.

--UPDATE 1 (15/09/2022)-- (THE REPAIR)

The device is on its way back to me from NSW, Australia, and I expect to receive it early next week (end-to-end, the total repair time will be around 3 weeks).

It's worth noting that the repairs are carries out by a service provider in Technocity (http://www.technocity.com.au/shops.html). The repairer was excellent, so I dealt directly with them. I requested for photos of the inside of the unit (photos 5 and 6 below). You can see there is internal corrosion.

They've advised me that they've replaced all the rusted parts, however no one has been able to answer my question: "won't it just rust again?" I'm hoping the screws (at the very least) have been replaced with galvanised or stainless steel ones.

Join me soon for my (re)unboxing!

--UPDATE 2 (03/10/2022)-- (THE REPAIR PART 2: REVENGE OF THE REPAIR)

I received the allegedly-repaired Dyad back on 19/09. Upon first use, it started to make a thumping noise, then a grinding noise, then the front roller stopped working. Something has gone wrong with the repair.

I emailed Roborock, who then advised me it's the wrong department. Then I emailed (they don't have a phone number) the Roborock AU store. They said they were happy to repair it again, however I'm not going through that twice.

After a couple of escalations, they've agreed to replace it for me. That was 21/09. I followed up on 27/09, and they've indicated I need to ship it to the repairer to confirm it is indeed broken (despite my comprehensive video evidence.)

I've now followed up again today to get the return shipping label.

Suffice to say I'm not happy, but let's keep going!
