is the 360 Vis Nav really this bad.

Update - so the latest replacement also just stops mid clean also. Very disillusioned. 

Same here. The robot “dies” mid-clean, just turns off, "Connection lost” in the app. Sometime after 3 mins, sometimes after 10 mins. But happens almost every clean!  Wasn't doing it at first, but after one of recent updates.

Wasn't offered a replacement, but a “repair” that would take unknown time. What should I do?

This seems to be the same as the old 360 eye. It just dies mid-clean and does not return to dock. I thought it is because its battery is old but apparently this is just the signature dyson software engineering. Unstable is one thing one would say… unusable is another.

Yes, it really is that bad.  I bought mine eight months ago, and the software is absolutely terrible.  Dyson refuses to answer any questions about missing functionality in the app, saying “they won’t comment about future product direction,” even though the Vis Nav is missing the most basic functionality...functionality that could be FIXED in an app update.  But Dyson won’t tell us anything about whether these features will be coming anytime soon...like maybe adding diagonal room dividers.  I’ve been waiting over 8 months, and have given up.  

Also, the bin fills quickly, and it doesn’t auto-empty.  And what’s up with it not being able to operate at night with low light?  My old Roomba that cost half the price can vacuum in the dark.  

I WANT TO LOVE THIS, but Dyson chose to put out a robot vacuum that doesn’t live up to the Dyson name.  I have a LOT of Dyson products, but this vacuum has been the worst Dyson product I’ve ever owned.  And Dyson’s lack of meaningful customer service means that customers who bought a VERY expensive vacuum are being strung along and treated really badly.  This vacuum is literally unusable.

Thanks for your insight. I am minded to give it one last roll of the dice with another replacement then return it within my 90 day window at the first sign of failure as so far with 3 of them I have only had one occasion where the £1000 machine finishes and job and return to the properly located dock. Strong hardware lousy programming and iffy optical  navigation. 

What's your software/firmware version?

I've got RB03PR.01.08.005.4317, wonder if that's the one they rolled back.

I'm getting a replacement now too.

Yep. I’m getting this behavior with scheduled cleaning and the room is furthest from the wifi access point where the base is located. Unlike my irobot which can handle switching to a stronger wifi access point, the dyson either is missing this feature or poor exception handling on weak wifi signal (i.e. pause, send notification to mobile app, etc.). After reading they are replacing units, I’m wondering if mine has broken hardware.

Got the replacement. The same. Worked ok for 2 weeks, then started dying mid-clean. Yesterday it died 3 times before I gave up.

Hi Daedra 

Sorry to hear that. So I have just paid £600 for a Roborock and it is so much better - laser navigation and whilst not as powerful as the Dyson it finishes the job and carpet is ultimately just as clean as does not need that power once on top of things. Charge lasts so much longer and on the one occasion it got stuck it has a resume setting. Better in every way. Makes me sad to say as a Dyson fan but imho the Vis Nav is underdeveloped, overpriced and only the Dyson service makes it even a contender.  It is not fit for my purpose and at £1000 is a bad joke. 
 

Sorry Dyson but there it is. 

Did you manage to return yours with full refund?

I had a 90 day return period or in truth would never have bought it given mixed reviews. Hopefully Dyson would take it back out of goodwill without your needing small claims action for the product not being fit for purpose. Make sure you have records of what has happened. Good luck.
