Quick winner

eufy Robot Lawn Mower E18 leads this comparison.

The winner is based on current MowScout Score and the yard-fit specs that matter for small flat-yard buyers choosing between the two simple vision models. That does not mean every buyer should choose it. A lower-scoring mower can still be the smarter purchase if it fits your lawn size, tree cover, slope, budget, or setup tolerance better. Treat this page as a structured decision guide, then run the configurator before buying.

The score gap is 1 points and the current street-price gap is $400. Those two numbers matter together. A small score gap with a large price gap may favor value; a large score gap may justify paying more if the added capability addresses your yard's hardest constraint.

Robot Lawn Mower E15

The smaller eufy model keeps the same no-RTK setup story for compact flat lawns.

Score67/100

It trails the comparison winner on the current score, but it can still be the smarter buy for the right lawn. For small flat-yard buyers choosing between the two simple vision models, the important specs are 0.2 acres of rated area, 32% slope support, VISION navigation, RWD drive, and 8 supported zones. Because this model avoids an external antenna, the setup path may be easier for buyers who want fewer install variables. The practical question is whether those strengths solve your hardest yard constraint or simply add capability you will not use.
