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

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

Robotstofzuiger

Hier ook de Dreame L40 Ultra rondrijden, ding werkt inderdaad echt fantastisch. Heb een huis met 2 kids en een hond dus er zwerven nog wel eens losse dingen door het huis (schoenen, speelgoed, kabels) en daar gaat hij moeiteloos mee om.

Ik heb uiteindelijk voor een Dreame L40 Ultra AE gekozen. Voornaamste reden is dat hij een thuisstation heeft en hij ook prima dweilt. Je hebt ze met allerlei verschillende dweilsystemen, de Dreame heeft 2 ronddraaiende pads die hij ook zelf schoonmaakt en minder water gebruikt dan veel anderen. De

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

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

Dreame L40s Ultra or Dreame L40 Ultra AE?

Yeah, the L40s Pro Ultra is basically Dreame’s “middle-child” model for Europe. It mixes the obstacle-avoidance hardware from the AE with the edge-cleaning and detergent setup from the L40s Ultra. It’s not super well-documented yet, but early listings look solid. If it’s close in price to the L40s U

New L40s Pro Ultra on old robot's map?

Dreame robots store maps in the cloud, not tied super tightly to the hardware. If the new L40s Pro Ultra is the same model and firmware family, restoring the old map is officially supported and often saves time. That said, a fresh remap is safer if any of these apply: The old unit had navigation qui

What’s the real difference between Dreame L50 Pro Ultra and L40S Pro Ultra? Is the L50 worth the extra $200?

The main upgrades on the L50 Pro Ultra vs L40S Pro Ultra are: Battery: 6,400 mAh vs 5,200 mAh (longer runtime, less mid-clean charging in big homes) Retractable LiDAR dome: lets it get under slightly lower furniture compared to the fixed L40S sensor Minor suction spec bump (19,500 vs 19,000 Pa — not
