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+23 pts“I’d go in with the understanding that the latest and greatest today will be outdated tomorrow.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.”

+11 pts“in the UK the two most talked about Roborock models aren't actually available (Qrevo CurvX and Saros 10R). Deals on Dreame seem better right now. I was considering a Saros 10 but just ordered an X50 Ultra, quite a bit cheaper plus seems like more robot for the money 🤷♂️”

+18 pts“I just went through a month of hell, dealing with dreame, trying to return an x50 for refund. I will NEVER own another one of their products after seeing their customer service in action. I had to send over 25 emails over the span of a month to finally get my return and refund completed. I can’t even imagine trying to work a warrant claim.”
