Best praise vs top criticism for Dreame X40 Ultra
“I am often surprised, and offended at how much difference there is in premium robots (which is what I tend to test, rather than budget or midrange). You should expect, if you pay that much, for a robot to work. This problem is much worse in lawnbots, but there is no condition under which I would purchase a Roomba or Eufy on purpose. Doesn't matter what model. I'm most impressed by Roborock, Dreame and Ecovacs. That said, each model is different. For instance, I thought the X40 was just fine. Didn't blow me out of the water. But I think the X50 is quite good, although it still has some navigation issues. I haven't tested the Monsga line, sorry.”
“Roborock saros 10r top of our list Eufy E25 2nd this is already at BF pricing according to eufy Dreame/mova same company and had x40 returned it Narwal not seeing the fantastic reviews from individuals and the onboard bin might be too small for 2000sqft home with 2 shepherds even with daily vac JMHO”
