The Dreame L40 Ultra gets closer to edges than the Qrevo Curv

The Dreame L40 Ultra has higher suction and reaches closer to edges than the Qrevo Curv, which makes a real difference on thick carpets over time. Dirt accumulates along skirting boards and baseboards, and the L40 gets at it.

The Qrevo Curv handles carpet well — there’s no question it cleans — but it’s more cautious near walls. It leaves a thin strip of uncleaned carpet along the edge that you’ll eventually notice. If your home has thick carpets and you care about edge-to-edge cleaning, the Dreame L40 Ultra earns its place.
