Roborock surprisingly didn’t do well in VacuumWars best vac/mop awards
In a more standardized test using lab-certified dust done by a German-based YouTube channel, Roborock's flagship has the weakest vacuuming power of embedded sand on carpet compared to Dreame, Roomba S9+, Dyson vis nav, and even Electrolux's first robot vacuum from the '90s. This is due to ineffectiv

is this a good find?
S9+ It came out in 2019 and is arguably the BEST roomba for straight cleaning performance especially carpet due to its large front rollers and non restrictive rear air exhaust. It still ranks on the top for robot vacuums based on cleaning performance especially on carpet It lacks obstacle avoidance

Teachers of Reddit, what are your most terrifying "Gen Alpha Can't Read/Behave/Etc." horror stories?
I'm GenX. I just bought a Roomba S9+ for super cheap at a thrift store. Took it home, and it worked pretty well, but it kept stopping with an error code that it was near an edge - there was no edge. After a bunch of rebooting and easy troubleshooting, it still had the same issue. More reading led me

Favorite model in terms of power
The roomba s9+ is the most powerful roomba The 2nd most powerful is the 980. Because both have exhaust fans on the rear of the unit, not downwards and could be obstructed by carpet like the i and j models, the s9 and 980 can provide consistent extreme suction on carpets.

L50 Pro Ultra seems just like X50 besides a few differences—what’s the catch?
I’ve had the Dreame L50 Pro Ultra for about two weeks now, and I’m honestly super happy with it. I upgraded from a Roomba S9+, and the difference is night and day. I was really torn between the L40s Pro Ultra, the L50 Pro Ultra, and the X50 Ultra. My home is completely flat (no thresholds/steps), so

CarefulDrive Question
All of the below is speculation. Why it's not available on all front-camera-based models (i.e. j5, j6, j7 too): probably just a matter of feature segmentation, just like how the PrecisionVision obstacles detection is only enabled to detect "pet waste" and wires/cables on the j6 series (it won't avoi

Quick question, do u guys life in your households? Cause my roomba gets caught on everything
The 690 is like the bare bones with very old tech. When iRobot switched to the rubber beater bars that really helped with getting tangled in wires and the cleaning/tracking was much more efficient. The j series brought object detection which means it usually will go around said object. The newest se

Flow 2 is great
My sentiments exactly. coming from an S9+ roomba. It was/is credible but the flow 2 is impressing me.Hope they up their game on the app soon. Map editing/tweaking is a PITA IMHO

Vacuum recommendations
We've seen great success with the Roomba S9+. We have two German Shedders. But you have to maintain the Roomba. Cleaning it often and cleaning the filters is a MUST.
