Roomba 620

No there was no air problem. I just could not give water. I also checked for chalk but there was none. I had it for 2 month or so and it was already defect. I asked what I can do and they said that I should send it back. Thats what I did. Then I bought the L10s ultra gen 2 and had it for about 2 month. Every time I started the robot it left big stains of water. It also was not mopping correct. There was always a dry line between the two mops. It is kind of unbelievable what garbage they are selling. My Roomba 620 is still working after 15 years. Of course it is a completely different thing but everything from dreame does work for two or three month or so. It is a joke. Also Ecovacs is imho total garbage. I had a Roborock which was better but I received it with a broken part in the station. Therefore I am looking for a new robot.

I’ve never understood this. I have an old Roomba 630 that “blindly bounces around” and it’s fine. Bought almost a decade ago and I still use it every day. Easy to get spare parts on eBay. I dread the day that it dies and I need to buy a cloud-connected model. How much better are these newer mapping / cloud-connected ones? Do they really add that much value?

Someone will buy it. The product line won't go away. Regardless the vacuum will work fine for a long time even if app access is lost. I have a 2014 version I still use on the regular. 

Probably a used roomba 600 series on eBay or FB marketplace. It’s reliable and parts can be found easily. It’s very no nonsense

Four cats, two with LOTS of hair. Our old Roomba 600-series works just fine, both on persian carpets and wooden flooring.
