the roomba, despite having worse navigation, seems much more reliable in terms of not getting stuck and emptying the bin every time

The J7+ Combo supposedly had great "poop avoidance" features but it ran over the poop and smeared it all over our floors on two separate occasions, lol.

What Roborock S8 MaxV Ultra owners say

it has been amazing so far. All I have to do is clean the air filter on the dust bin every 3 days and change the bag out every 3 weeks or so when I refill the detergent. Come home every day to perfectly clean floors with extremely minimal maintenance.
