X20+

I've a xiaomi x20+ which mops with rotating disks.  if there is a dried stain it doesn't clean it, but after mopping the floor feels noticeably cleaner to my bare feet, and the dirty water tank is definitely dirty!

I personally can heavily recommend Xiaomi. Idk how exactly the circumstances are, but Xiaomi and Roborock make the same vacuumrobots with Roborock just doing the "premium line". But you will get 90% of what the Roborock does, but mutliple times cheaper. Just compare the Xiaomi X20+ with the Roborock S7 Max Ultra and their prices when they released... idk was like 500€ vs 1800€. Our old Ecovacs constantly rotated its map and thus was completely useless.

I have a dog and have a Xiaomi X20+. While it is great for cleaning, the main issue is that you cannot add cleaning solutions to them. They expect you to wash with just water, which is not enough. It won't eat dog's toys, but it will push them around or go around them. That said, there are cleaning solutions online but they are a tad pricey.

Here's a review of my Xiaomi X20+ Positives: bargain price, good mopping, good tank size, effective vacuuming (into the robot), capable app with good mapping, surprisingly good object avoidance, solidly built. Negatives: carpets have to be entered manually on the map, dust emptying (from the robot to the base station) often inadequate meaning the machine has to be regularly cleaned out manually; finger dexterity required. The biggest negative is the failure to empty the dust properly. It actually would be a deal breaker for me had I known this beforehand. I assumed it might improve over time as the vacuum cleaner got rid of the worst, but it hasn't Would I recommend it? If you don't have pets and keep tidy home with very few hairs on the floor, just light dust, and you need good mopping, then yes at this price it's a bargain and will probably do the job. If you need a capable vacuum cleaner which can deal with even small amounts of hair and fluff, then no. Owned for about 2 months now and in use fairly regularly.

S20+ and the l10s ultra gen 2 are miles apart. I’d get the l10s ultra gen 2 since it’s at the same price. Same if you meant the X20+

The Xiaomi X20+ can also use the same antitangle brush.

The x20+ is going to be a pretty good budget choice for you.
