Welche Anschaffung habt ihr 2025 getätigt, die ihr absolut nicht bereut habt?
Hab mir zu Weihnachten den Dreame l40s Pro Ultra gekauft. Das Ding geht wie Sau. Wohnung ist echt super sauber. Vorausgesetzt er kommt überall hin. Kannst alles auf dem Boden liegen lassen, die Kamera Erkennung ist brutal gut. Zu black Friday gab’s den für ca 600€. Und wenn du nur ein bis zwei Mal d

Megéri a robotporszívó, álló porszívó mellett?
Belépő szintű szerintem pénzkidobás(de szerintem még a középkategória alja is). Ha csak mechanikai ütközésérzékelős, akkor a "térkép" is elég gyatra lesz, sok mindennek neki fog ütközni, ami hosszú takarítási időt fog eredményezni. A LIDAR-osok már jobbak. Annak se látom értelmét, mikor a por meg ví

should I get a dreame or roborock - ecovacs disapointed me hard
I have a Dreame L40s Pro Ultra. The first 6 months were great. Other than filling/emptying tanks and bags, washing mop pags etc, it just did its thing and cleaned daily. The object avoidance was quite good and it rarely got stuck. But then it stopped being able to mop. I reached out to Dreame AU sup

Anyone switched from Roborock to a new robot vacuum company?
I moved to Dreame, my L40 ultra refurbished did absolutely amazing with obstacle avoidance, I just bought a L40s Ultra AE for my basement to replace a Roborock Q5+. Meanwhile my Saros 10 which mind you cost $1,500 new keeps getting caught on shit. Recommend getting the tricut brush (yes it's expensi

Robot Vacuum: A Need or A Hyperixation?
Will you be able to keep the floor clean enough to use it (or get one smart enough to avoid obstacles)? I had a perfectly good robovac but I stopped using it because I'm really bad at keeping the floor clear. Earlier this year, I upgraded to one with camera-based obstacle detection in addition to LI

Considering replacing trusty Roborock S5 with a flavor of Eureka J15
I have an S4 Max in Home Assistant (not eligible for Valetudo) and moved onto a Dreame L40 Ultra (with Valetudo). The L40 Ultra has great Valetudo support and similar functionality that you are looking for, it also regularly goes on sale for even cheaper. L40 Ultra / Valetudo features with it... Has

Confused by Dreame’s naming? Here’s a simple cheat sheet.
Yea I take back my statement on that. I have a L40s Ultra AE for the first floor (all wood), works great, love the camera. I needed a second vacuum for the second floor, a lot of carpet so I was intrigued by the increased vac power. I ended up just ordering a second L40s Ultra AE from Dreame's ebay

L50 ultra vs L40 ultra Gen 2?
The Dreame L40 Ultra Gen 2 actually has the stronger suction at 25,000 Pa, while the L50 Ultra has 19,500 Pa. That said, the difference in real-world performance comes down to design focus: L40 Ultra Gen 2 (25,000 Pa): Higher raw suction power for deeper carpet extraction and stronger pickup of embe

L40 Ultra "gen 2"
As an owner of both an L10s Ultra and L40 Ultra.. the L40 is sooo much better. It cleans better, is way better at obstacles, way longer runtime, etc. I recently got the refurb L40 on Dream's eBay shop for $250 US, hard to beat that. I'm actually hoping another one shows up so I can ditch the L10s ul
