A neatly cut lawn takes more work than it looks, and finding the time can be difficult, between work obligations, as well as recreational events and activities that all require some of your free time. Trusted by more than 750,000 families worldwide, MAMMOTION’s latest robot mowers can keep the grass maintained throughout the week without monopolizing your schedule. The timing is particularly good if you have been considering one: From August 12 to 31, MAMMOTION is discounting both the flagship LUBA 3 AWD 3000H and the LUBA mini 2 AWD 1500H as part of its 10th Anniversary Sale, with savings up to $560 plus a free Mower Wash Stand worth $79. New customers will also get $50 when making an online store purchase. Features that matter most in a robot lawn mower A good robot mower should maintain the lawn with little input once the schedule is set. These five features have the biggest impact on how reliably it works and how much time it saves you. Navigation to every part of your lawn Credit: MAMMOTION Smart, reliable navigation helps a robot mower cut in straight, evenly spaced lines without missing grass or covering the same area twice. Robot lawn mowers typically rely on RTK for wide, open lawns or a combination of LiDAR and cameras for areas under trees or around buildings, where satellite reception may be weaker. The LUBA 3 AWD combines all three through MAMMOTION’s Tri-Fusion Navigation System. It can navigate complex lawns and mow in straight lines even across broad, open areas, where LiDAR-only robot mowers can struggle. Unlike previous models, the LUBA 3 now features Network RTK, which works over 4G across the US, meaning there is no need to bury boundary wires or install a local RTK reference station. Handling slopes and uneven ground Credit: MAMMOTION All-wheel drive may not be essential for a small, flat lawn, but it can make a major difference on slopes, damp grass, and uneven ground. The LUBA 3 AWD and LUBA mini 2 AWD use independently driven wheels to climb gradients of up to 80%, or 38.6 degrees, and cross roots, curbs, and other rough sections. That means fewer stalls and fewer trips outside to rescue the mower. Avoidance of people, pets, and other obstacles Family lawns are rarely completely clear. Toys and garden furniture get left behind, while pets may wander into the mower’s path. The LUBA 3 AWD uses cameras to recognize and avoid more than 300 types of obstacles, while the LUBA mini 2 AWD uses 360-degree LiDAR to scan its surroundings without blind spots, including in low light. Completing the job quickly A mower can navigate accurately and still be inconvenient if it takes all day to cover the lawn. With a 15.7-inch cutting path and two cutting discs, the LUBA 3 AWD can mow up to 5,400 square feet per hour and cover as much as 0.42 acres per charge. It runs for more than three hours, returns to recharge when necessary, and resumes where it stopped. While robot mowers cut more frequently than traditional mowers, their electricity use remains relatively low. A typical model uses around 4 to 8 kWh per month to maintain a 1,000-square-meter lawn during the mowing season, without using gasoline or producing direct exhaust emissions. The LUBA 3 also adjusts its power use based on grass thickness, helping it maintain a clean cut while using less energy. Simple and thorough app control A useful app should reduce work rather than give you another screen to manage. The LUBA 3 AWD lets you divide a property into as many as 50 zones, then give each one its own schedule, cutting height, and mowing route. You can also save up to 10 maps, create lawn patterns, limit how fully the battery charges, and schedule charging during off-peak hours. The result is a mower that can accommodate different parts of the yard without requiring you to adjust it every time. Choosing the right LUBA for your lawn Both LUBA models bring MAMMOTION’s AWD traction to slopes and uneven ground, but each is built for a different type of lawn. The right choice comes down to the size and layout of your property, including how much open ground it has and whether the mower needs to navigate around trees, walls, and narrow passages. LUBA 3 AWD 3000H: For large, complicated lawns MAMMOTION LUBA 3 AWD Brand Mammotion Cutting Height Standard Version 1.0"-2.7" / High Version 2.2"-4.0" Maximum gradient 80% Normal running time 215 minutes The MAMMOTION LUBA 3 is made to tackle larger backyards, mowing 0.42 acres at a time. But not all yards are the same, with obstacles and gradients to contend with. To contend with this, the LUBA 3 has Tri-Fusion Navigation, LiDAR, and cameras so that it's always on track and avoids objects. The LUBA 3 AWD 3000H has a lot going for it, but its biggest advantage is how quickly it can cover ground, making it ideal for large, open lawns. Its two cutting discs provide a 15.7-inch cutting width, so it cuts more grass with each pass than the LUBA mini 2. A larger battery enables it to mow up to 0.42 acres per charge, making the LUBA 3 the better choice when you need to cover a large lawn in less time. Credit: MAMMOTION That said, large lawns are not always simple, which is where Tri-Fusion Navigation comes in. Network RTK keeps the mower on course across open grass, where LiDAR alone might struggle. That said, it still has LiDAR and cameras to help mow efficiently around trees and buildings. You can also manage up to 50 zones through the app, and iNavi NetRTK removes the need for a boundary wire or local reference antenna. LUBA mini 2 AWD 1500H: For smaller lawns and tighter spaces MAMMOTION LUBA mini 2 AWD Navigation 360 LiDAR and Dual-Camera AI Vision Waterproof Rating IPX6 Brand MAMMOTION Normal running time 150 minutes MAMMOTION's LUBA mini 2 is adept at keeping smaller lawns fully manicured. Its smaller footprint allows it to navigate smaller spaces freely, so every inch of grass is covered. It has a larger main cutting disc designated for most of the mowing responsibility, as well as a smaller side disk to get close to edges and fences. This model has 360-degree LiDAR and handles slopes. The LUBA mini 2 AWD 1500H is designed for smaller lawns with narrow sections, fence lines, and flower beds. Its main cutting disc works alongside a smaller side disc that cuts closer to the edges, leaving less grass for you to trim manually. Credit: MAMMOTION Its smaller body can move through tighter spaces, while 360-degree LiDAR and vision map the lawn during the day or at night. It does not cover open ground as quickly as the LUBA 3, but it can handle the same slopes of up to 80%. DropMow mode also lets you mow a temporary area without saving a new map. Save during MAMMOTION’s 10th anniversary sale MAMMOTION’s 10th Anniversary Sale runs until August 31. The LUBA 3 AWD 3000H receives the larger discount, reducing by $560 to $2,239, while the LUBA mini 2 AWD 1500H is $200 off at $1,799. Both models come with a free Mower Wash Stand worth $79.

Either way, the discounts make this a better time to take regular mowing off your weekend schedule.
