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

My t30s ai no issue at all after 18mths of use daily /twice daily 1000sq ft engineered hardwood and wools rugs
I run my whole smart home primarily on smartthings, about 150 devices, so it can definitely work as a great platform. One of the problems though, is that any premium device type that Samsung makes (Washer, dryer, vacuum, tv) they always make the third party integrations either not function or be pretty much useless if it does. They want you to buy the Samsung stuff at a $$ premium. For a vacuum I use an ecovacs vacuum mop combo. It doesn't work with smartthings, but because my robot vacuum doesn't really need to interact with anything else, it's never been an issue. Highly recommend ecovacs, roborock, or eufy as brands.
I honestly want nothing to do with the new models. I have A T30S. I've had it for two years and it does exactly what it's supposed to do. Personally, I would stick to the older models That have a decent track record. The new models are too expensive and you can find them for 50% off just 18 months later.
Longtime Neato, Roomba, and Braava owner here. Tried smarter bots and found the Ecovacs Deebot T30S disappointing but am very happy with two Dreame X50 Ultra bots, one white and one black. My Roomba 980 and Neato XV Signature Pro are still good for turning loose in areas the new ones can't get to by themselves. Tried a new Roomba Combo to future-proof those areas but it was basically a downgrade. We wore out the little Braava 380t, but I haven't looked for parts because the Dreame bots do a much better job with much less effort from me.
In USA they seem to cover warranties without argument. I don't think much of the features or the quality, but Ecovacs did replace my Deebot T30S when the dock started leaking. The replacement is for sale now because I've moved on to Dreame, but I may try an Ecovacs window bot as they seem to have unique expertise in that area.
Read the reviews. The Dreame X50 has won awards and most of their lineup is highly regarded. I haven't tried the top-of-the-line Ecovacs but I had a midrange T30S and the Dreame X50 Ultra is so vastly superior I bought a second one to replace the Ecovacs.
I had a T30S which is a mid-range model so this is not a 1-to-1 comparison with the top-of-the-line Dreame X50 Ultra. I suspect T50 is also mid-range and that something like the Ecovacs X90 would be a better comparison. Having said that, I'll just say that the T30S drop sensors, optical encoders, climbing, navigation, mapping and app features are inferior to the X50 Ultra's. When the T30S dock sprung a leak, Ecovacs would not engage with me about a replacement part and just replaced the whole package — a leak and a swap being situation normal with any of these Chinese brands — so since I was going to lose the map anyway I decided to replace the replacement with a second Dreame X50 Ultra. Have not regretted it one bit.
I’ve got ecovacs model too, and it is t30s. A robot vacuum really saves me a lot of time with floor cleaning, and this one I’ve been using it for a few months now, no major problem so far.
Maybe. But the discounts can change from year to year, I got my deebot during last year’s bf. I’m actually proud that I’ve managed to keep up the habit of cleaning it regularly ever since:)
We have a ecovacs deebot T30s doing about 1200 sqft and it works well for daily stuff, but it DOES NOT replace actual mopping. No robot can fully replace vacuuming or mopping, they’re more for ongoing maintenance. You still need to do a deep clean once a month or so, properly two-bucket mop, and vacuum all the corners. That said, it’s amazing and we’re so glad we have it!
