I got the Roborock QX Revo Arc for $600 flat at Costco and it's already paid for itself in just a couple of months. We used to need housekeeper every 2 weeks cause the kitchen and dog area was just disgusting esp with the self feeding toddler. I would spend sooo much time vacuuming and swifering and it was still so gross. We only need housekeeper every 3 weeks now, saving like $2K a year now. Even if the robot breaks down after a year from us running it 3x a day I'm still saving $1400 lol
By the QX Revo Arc, and try it yourself, the best way to know how good something is, is to try it yourself, sometimes, you just gotta take advantage of costcos return policy lmao
If you want to buy from Costco, the qx revo arc, everything about is good except for the obstacle avoidance which is pretty bad.
If you want some other options, you could get a roller mop vac from amazon like the eufy e25(will require more maintenance, but it’s a roller mop)
I have what I think is called the [Roborock QX Revo Arc Robot Vacuum and Mop with Duo Anti-Tangle System | Costco](https://www.costco.com/p/-/roborock-qx-revo-arc-robot-vacuum-and-mop-with-duo-anti-tangle-system/4000400650?langId=-1). It has the Duo anti-tangle system...according to the ad. My model has an attempted solution for the beater brush by making it 2 pieces. I do not know if it works as I don't have a shedding dog. The second of your issues is the clogged vacuum tank. If you are referring to it not clearing at the dock, I found this on mine, with a new rug. The tank would only partially clear during the Dock session. I manually cleared it and will try again.
The Revo Arc does require bag changes every 5ish runs in a 2500sqft home with two short haired dogs. The mopping will empty clean water after two full runs. You should also clean the mop cleaner tray often so muck doesn't dry on and be painful to clean off.
I have had mine 3 weeks and I will be checking the rollers tonight as well.
There is maintenance with the Arc, but frequency and environment will determine how often.
I went the Costco route so that I could return it should it suck.

Reliable, great mopping (lifts pads), but poor cable avoidance.
