Amazon is hosting its fifth consecutive October Prime Day sale, featuring some of the best discounts we've ever seen -- especially on big-ticket items like robot mowers. The Ecovacs Goat A3000 is one of the best LiDAR robot mowers I've used, and I wholeheartedly recommend it for people with a fenced-in yard, even if you have garden beds. This mower performs very well, capable of handling up to 0.75 acres a day. It's typically priced at $3,000, but a Prime Big Deal has dropped its price by 31%, making it available for $2,085.

Because it uses LiDAR for navigation and mapping, the Ecovacs Goat A3000 robot mower doesn't require you to dig a boundary wire around the perimeter of your yard or to waste an afternoon finding the best spot for an RTK antenna. Instead, this robot operates similarly to a robot vacuum: its set of 360-degree LiDAR and ToF sensors captures its surroundings, and the robot processes the information to recognize what is in front of it.

Aside from offering the easiest installation you can find from a robot mower, this model works best in yards that have clear visual or physical boundaries. If you have garden beds you'd like the mower to avoid, it's best if they're clearly defined with mulch, gravel, or a border, though you can also add no-go zones after creating a map. The Ecovacs Goat A3000 LiDAR has a 13-inch cutting width, which is very generous in the robot mower market. Its wide cutting area reaches almost to the edge of the mower, offering one of the closest-edge cuttings I've seen thus far. This mower can handle slopes of up to 50%, and you can adjust its cutting height between 1.2-3.5 inches. I run my robot mowers a few times a week to keep the grass trimmed, so I appreciate being able to control everything from my phone app. I can set the Goat A3000 to cut specific areas, trim edges, or even handle heavy-duty mowing for overgrown areas or an initial mow. For a limited time, you can get the Ecovacs Goat A3000 LiDAR for $2,085, down from $3,000, during Amazon's October Prime Day sale, happening now. More Prime Day robot mower deals How I rated this deal I gave this deal a 4/5 because it's one of the best prices I've seen for a robot mower of its caliber. This deal for a LiDAR-powered robot mower stands out because it's a truly plug-and-play device that doesn't require extensive tinkering or a complex setup. Having tested and compared multiple robot mowers, I can confidently say that this $910 discount makes the Goat A3000 LiDAR one of the best buys during Prime Day for anyone looking to reclaim their weekends from yardwork. When will this deal expire? This deal appears to be a part of the Amazon Prime Big Deal Days, also known as October Prime Day, so I'd expect it to expire when the end of the event rolls around on Oct. 8. While many sales events feature deals for a specific length of time, these deals are often limited-time offers, making them subject to expiration at any moment.
