X50 - far better than its reputation in here
Totally agree — it's refreshing to hear some positivity! Most folks (understandably) post here when something goes wrong, but the silent majority probably have experiences closer to yours. I’ve been running an L40 Ultra for about a month and it's been similar: hands-off, reliable, and shockingly low

AMA - Robotporszívó tesztelőként dolgozok évek óta, mire figyelj oda ha robotporszívót vennél?
vacumwarst imádom, szerintem jó, követem évek óta. Szinte mindig ugyanazok jönnek ki nála, mint nálunk. (Csak sajnos sok modell nem elérhető) Rtings kevésbé, egyéb területeken (pl. füles, gaming egér) nagyon jók, itt kevésbé, szerintem nem értenek annyira hozzá csak kellenek a látogatók :D Én a legj

Anyone still using the Dreame L10s Ultra?
I loved my L40 Ultra until it wouldn't recharge and started acting crazy. Sent it in on the warranty I bought with Amazon, and they refunded me the same day they got it! Ordered a new Dreame via the Reddit special, the X60 Max Ultra complete. Will see how that is vs the L40 Ultra. Enjoy yours - it's

Best self emptying robot vacuum that can be an alternative to Roborock?
I got dreame l40s pro ultra instead of curv 5a1 and I’m really surprised with it! No regrets

Dreame L40s Ultra or Dreame L40 Ultra AE?
I was looking at various Roborock models too. The Dreame L40s Pro seems to have a lot better features compared to the Roborock models priced up to £500 that th L40s Pro Ultra is currently on offer for.

Dreame L40s Ultra or Dreame L40 Ultra AE?
Went with the L40S Pro Ultra, returned it because even though it was good, its extra features weren’t worth the extra price. Picking up the Dreame L40 Ultra AE instead with a 5 year warranty plan so I’m guaranteed it lasts. Do feel like the Dreames are more delicate than Roborocks.

Saros 10R or Z70 or New QRevo Edge 2 Pro
I got a 10R to replace a failed Dreame L40s Pro Ultra that Dreame wouldn't/couldn't fix.I should have researched further as apparnetly they're both White Labelled Xiaomi vacuums. Anyway, it works fine. It's not quite as good as the L40s PU I had in these ways:- Lack of LIDAR, the TOF sensor is just

Dream L40 AE Ultra
The main difference between the L40s Ultra and the L40 Ultra AE comes down to overall cleaning performance vs value. While both have strong suction on paper, the L40s Ultra is the more premium model with a better dual-brush system, more precise edge cleaning, and a more refined mopping performance,

Robotdammsugare, VILKEN SKA MAN HA?!
Dreame är ett fantastiskt märke. Har en l40 ultra som är grym. Roborock är också bra, men lite väl dyr i jämförelse. Du får lika bra, till och med bättre, prestanda med en dreame.

dreame L40s Pro Ultra / Matter Support ?
The L40s Pro Ultra already has Matter support rolling out via firmware 4.3.9_3276. A few people have confirmed they’re running it now, so the hardware itself isn’t the blocker. If you don’t see it yet, it’s almost certainly just a staged rollout by region, which Dreame tends to do pretty slowly.
