Robot lawn mowers have gotten a lot better over the last couple of years, but the ones that can deal with a big or hilly yard still cost a pretty penny. Right now, Mammotion is taking $560 off the LUBA 3 AWD 3000H, which brings it down to $2,239, from $2,799, and $200 off the smaller LUBA mini 2 AWD 1500H, down to $1,799, from $1,999, through Aug. 31.
The LUBA 3 deal is at Amazon, while the mini 2 is on Mammotion's own store, where new customers can also grab a coupon for an additional $50 off. Both offers also come with a free $79 cleaning stand, so that's some more bang for your buck.
The LUBA 3 AWD 3000H is the bigger mower of the two, and it's the follow-up to the LUBA 2, which is our pick for the best robot mower overall after a year of testing. We haven't tested the LUBA 3 yet, but it gets some significant upgrades over the last model.
Most robot mowers that use satellite positioning need a separate base-station antenna mounted somewhere with a clear view of the sky. Positioning that antenna ends up mattering a lot, and it can be a hassle. The LUBA 3 has NetRTK, which is basically the ability to receive satellite corrections over 4G or Wi-Fi instead. That makes the setup much simpler, letting you set it up by pretty much just walking the mower around the edge of your lawn with the app.
You get a 360-degree LiDAR sensor and a pair of cameras to handle the obstacles. Mammotion says it can recognize more than 300 types of obstacles, so it should be able to steer around the kids' toys and the dog on its own. It'll also switch between satellite and LiDAR based on the situation.
The LUBA 3 is rated for yards up to 0.75 acres, and the app lets you split that into as many as 30 zones, so you can use different schedules for the front, the back, and the driveway. All four wheels have their own motor, which is why it can climb slopes as steep as an 80% incline, which is steeper than most people would want to push a regular mower up. The suspension also lets it roll over curbs and roots up to 50 mm, or about 2 inches, high.
