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

I’m a big fan of my dreame x30
As long as you have a 'no questions asked' decent return policy....then it's an OK model. (I think the battery may be a little less than average before it has to return to the dock.) Put it through it's paces a lot. I mean a lot! You don't want to find an intermittent problem that only becomes apparent after the return period has expired.
Dreame's and MOVA's robots with an extending mop will excel at cleaning edges like these since the algorithm is very aggressive compared to other brands. Any model from the X30 Ultra and newer or the P10 Pro Ultra and newer can do this.
1. Anything that moves can break. So I suggest buying from a retailer with a good return policy + a good protection plan. 2. For base station cleaning: Dreame (some models), eufy, Narwal, roborock, and Xiaomi have completely removable mop washboards. I’m not a fan of the wiper driven mop washboards on the Dreame X/L30 and X/L40 ultra and the MOVA P10 Ultra/Pro Ultra simply because there’s too many nook and crannies to clean. However their new aceclean dryboard on the L/V/X50 Ultra and newer is much easier to clean even when only the filter is removable since there’s no nooks and crannies for dirt to hide in and dirt only really collects under the removable filter which is easily removed with a wet wipe or a Clorox wipe. I’d avoid bagless base stations. Spinning mop combo robots are less maintenance than roller mop robots.
I have the dream x30. Wonderful robot. Have it set up to vacuum and mop daily and floors are great. One feature I thought I'd never care for is the remote access. You can connect to the robot and drive it around. Been useful on vacation.
I have a Dreame X30 and bought the cutting blade for it. It has a blade under the bristles so it can cut the hairs into smaller pieces. It doesn’t cut cords though. It has object detection to avoid things like toys and poop. Buy the refurbished version from the official store on EBay. There’s often a 20% off coupon. The refurbs are just new units they sell discounted so it doesn’t undercut the new ridiculous sales price. I’ve had it for about 9 months now and it’s been amazing. It vacuums and mops. It cleans its own mop pads and self empties.
Well I had a similar experience when I bought the X30. Sent it to them for repair, took 4 months to get it back, and it broke within 8 months. Sent to repair again, and complained about it to them that it takes a long time. I do feel like you that they take so long to reply to emails. I guess I got "lucky", in my case they sent me a free upgrade (X40), The only strange thing is that they told me to remove my negative review from Amazon to get the free upgrade.
My original X30 got a crack in the front wheel housing (after 4 months of daily use). I think it happened because I have 3 dogs and hair got caught up inside of the wheel, I wasn't aware until I noticed that it kept making a dragging noise and struggled to turn. I removed the front wheel and cleaned it, but it turns out that the hair was holding it together, so once cleaned the front wheel kept falling out due to the large crack. Dreame sent me a new X30. The issue I had with the second one was that it refused to drain and the overflow sensor stopped working, so after every session there was a huge puddle of water around the base station. It was either the pump had gone bad or there was a clog in the line inside of the base station. (Happened after 4 months of daily use)
