Best praise vs top criticism for Dreame L40 Ultra
Best Praise
+23 pts“I’d go in with the understanding that the latest and greatest today will be outdated tomorrow. So I went for the best bang for my buck. I just got a Dreame L40 which was only $475. I actually like the performance. And really if money wasn’t an issue, I’d do a nice professional install to hook it up to my plumbing so I don’t have to fill it up or empty the dirty water. Then by a new best band for buck model every few years. If money is no o next and I could wait for it to come to the US I’d probably get the Dreame L40S (notice the s) which has 19,900 Pa for vacuum or Dreame x50 (dreames X line is their top of the line while the L is more midrange. With that said, I feel that Roborock is the more solid and reliable brand. But Dreame has its bells and whistles. Theres a lot of debate over mopping. Roller vs spinning. And for me personally with light traffic and a no shoes indoor home, I find the spinning mop good. The base washes the mop with hot water, and it picks up a lot of dirt. I also go to vacuum wars for reviews. Their top is Ecovacs, roborock, Yeedi and Dreame/Mova (mova is subsidiary of Dreame) Not everyone is impressed with Dreame but I like it so far.”

+8 pts“There’s also a Roborock specific sub with a lot of q revo discussion that’s not in this sub. I am always recommending the q revo from Costco because a lifetime return policy for a robot is amazing with all the wear & tear it gets”
r/RobotVacuums
ViewTop Criticism
+19 pts“I agree, robot vacuums have BY FAR some of the most confusing naming conventions. For example, you look at the Roborock moderately priced Qrevo series. You have: Qrevo Series Qrevo Slim Qrevo Master Qrevo MaxV Qrevo Plus Qrevo Pro Qrevo S Qrevo Who the hell comes up with these names? You can barely remember what is what, even if you are familiar with the brand!”
