Dreame L40 Ultra vs Qrevo Curv: L40 wins for edge-to-edge carpet cleaning

The Dreame L40 Ultra reaches closer to edges and has higher suction, making a real difference on thick carpets over time. The Qrevo Curv cleans well but leaves a thin strip of uncleaned carpet along skirting boards and baseboards. If you care about edge-to-edge cleaning on thick carpets, the L40 earns its place.
