Eufy and Mammotion Tackle Robot Mowers' Last Manual Chore: Edge Trimming

At IFA 2026, Eufy and Mammotion both unveiled robot mowers with edge-trimming capabilities, targeting the perimeter strips that prior generations left for manual string trimming. Eufy's S2 Max uses an extendable trimming arm; Mammotion's Luba 4 AWD uses an edge-cutting attachment — though its largest 3-acre model lacks the feature. Edge finishing follows navigation as the category's next battleground.
