Impossible – My Two-Month Experience with the Mammotion Luba
Owning the Mammotion Luba has felt like dating that gorgeous, high-maintenance girlfriend who promises the world, dazzles you at first sight… and then slowly drives you mad. After two months together, I’m ready to break up. I live in Denmark, and before purchasing I made sure that Luba’s integrated SIM-based 4G navigation was supported here. I was assured it was – and technically, it is – but in reality, it works very poorly. Almost daily (or at best every other day) I get the error telling me to “install the RTK antenna,” which makes no sense because in my country SIM navigation is supported. To clear the error, I usually have to restart the robot, and often even reset it entirely. This means losing my map and having to remap my garden at least once, sometimes twice, a week. Obstacle avoidance is equally disappointing. I have it set to high sensitivity, but it fails to detect garden hoses, children’s toys, and even 7-cm-tall stone tiles – it ran straight over them and damaged the blades. The only things it reliably avoids are very large, obvious objects like trees. For a 2,500-euro mower claiming advanced navigation, this is unacceptable. The problem isn’t the cutting quality – when it works, it cuts well. The issue lies in the poorly designed navigation system and app. Luba only performs consistently if you have a perfect, obstacle-free lawn where it can run the exact same pattern every day. My garden has five raised beds and various children’s play items – in practice, I have to “prepare” the space before each mow, which defeats the whole point of an autonomous mower. Customer support is another disaster. Not only is communication slow, but the agents clearly have little product knowledge, often respond with irrelevant scripted replies, and struggle with clear English. Every interaction leaves me more frustrated. Other daily frustrations include: • Frequent loss of Bluetooth or Wi-Fi recognition, requiring me to physically carry the mower to the lawn. • Random overnight changes to settings and language after automatic updates. • Skipping entire lawn sections for no apparent reason. • An inflexible app that doesn’t allow splitting or editing maps without remapping from scratch. • Complete inability to navigate dynamically like a modern indoor robot vacuum – if a narrow path between the base and the lawn is blocked, it simply stops instead of finding a way around. For the price, I expected a product that could run on schedule with minimal intervention. Instead, I spend more time monitoring, resetting, and remapping Luba than I would actually mowing the lawn myself. Bottom line: The concept is excellent, but the execution is deeply flawed. The Luba is not worth €2,500 in its current state. If I could, I would return it without hesitation.
