The Grimsholm Green Wall Mount is a dedicated storage solution for the Mammotion Luba 2 AWD robotic mower. Designed to hold the mower securely against a wall, it helps homeowners reclaim valuable floor space in garages, sheds, or workshops. This mount is particularly useful for anyone looking for safe winter storage or a more organized storage area.
Its primary benefit is space efficiency. By raising the mower off the ground, the mount prevents the unit from taking up floor space and reduces the risk of accidental bumps or damage.

As long as it is anchored to solid wall studs or masonry, it should provide a stable, long-lasting storage solution. There are no complex moving parts, which means less that can go wrong over time.
The main limitation is compatibility: it is made specifically for the Mammotion Luba 2 AWD, so owners of other robot mower models will need to look elsewhere. Also, because the product is relatively new, there is no extensive track record of long-term performance from other users. This is something to consider if you prefer products with a larger base of customer reviews.
For Mammotion Luba 2 AWD owners who need to maximize space and protect their investment during the off-season, the Grimsholm Green Wall Mount is a practical choice. It offers a secure, space-saving storage option at a reasonable price point. If you have a solid wall to mount it on, this bracket will keep your mower safe and out of the way until the next mowing season.

Buying Guide for RTK-Free Robot Mowers
When shopping for a robot mower that doesn’t depend on RTK, focus on these critical aspects. They directly affect performance, reliability, and ease of use.
Navigation Technology Without RTK
The best RTK-free mowers use a mix of LiDAR, AI vision, and inertial sensors. For example, the Mammotion LUBA 3 AWD combines 360° LiDAR with dual cameras to map your yard in real time. This system identifies over 300 obstacle types and avoids them without needing a satellite fix. If you want a mower that navigates reliably even under dense trees or near buildings, prioritize models with sensor fusion rather than pure RTK.
For a deeper dive into hybrid navigation, read our Best Hybrid Navigation Mower for Rough Terrain article. It explains how LiDAR and vision work together to handle slopes and obstacles.
Terrain Adaptability and Slope Handling
Without RTK, the mower must rely on its own torque and suspension to climb slopes. The Mammotion LUBA 3 AWD features four independent motors and adaptive suspension, letting it conquer slopes up to 80% (38.6°). Its omni wheels pivot 360 degrees, so you get tight turns without damaging the turf. For existing Dreame A2 owners, upgrading to the Mammotion Omni Wheels for LUBA 2 AWD/LUBA mini AWD can dramatically improve mobility on uneven ground without requiring any RTK setup.
If you frequently mow hills or bumpy lawns, check out our All-Terrain Mowers category for more options built for rough conditions.
Cutting Performance and Battery Life
RTK-free mowers still need strong cutting power. Look for models with dual high-torque motors and intelligent speed adjustment. The LUBA 3 AWD uses two 165W motors with six blades, automatically adjusting speed based on grass density. It runs up to 175 minutes per charge, covering 500 m² per hour. That means you can handle medium to large lawns without frequent recharges. For smaller yards, the same accessory platform works well with the best dreame robot mower models that don’t require boundary wires.
Storage and Maintenance Accessories
Even the best mower needs proper storage. The Wall Mount for Mammotion Luba 2 AWD from Grimsholm Green keeps your machine off the ground and saves space. It’s especially useful during winter months or when you want to avoid floor clutter. A clean, dry storage spot extends the life of your mower’s battery and chassis. This accessory works with most Mammotion models and is a smart addition if you’re moving away from RTK-dependent systems.

Frequently Asked Questions
Can I use the Dreame A2 without RTK?
The Dreame A2 is designed to work with RTK for boundary-free navigation. However, you can use it in a limited area without RTK by setting manual boundaries, but accuracy and coverage will suffer. For full RTK-free performance, consider a model like the Mammotion LUBA 3 AWD that uses LiDAR and vision instead.
What is the best robot mower that doesn’t need RTK in 2026?
In 2026, the Mammotion LUBA 3 AWD 3000 is widely regarded as the top RTK-free option. Its combination of 360° LiDAR, AI vision, and NetRTK (which uses internet-based corrections rather than a local base station) gives you reliable navigation without a dedicated RTK setup. For budget-conscious buyers, adding omnidirectional wheels to an existing Mammotion model is a great upgrade.
How does LiDAR compare to RTK for lawn mowing?
LiDAR creates a 3D map of your yard using laser pulses, working even under tree cover or near buildings. RTK relies on satellite signals and a base station, which can be blocked or require line-of-sight. LiDAR is more forgiving in complex environments, while RTK offers centimeter-level accuracy when signals are strong. For most homeowners, a LiDAR-based system provides sufficient precision without extra infrastructure.
Are Mammotion mowers compatible with Dreame accessories?
No, Mammotion and Dreame use different chassis and mounting systems. However, the accessories we recommend, such as the wall mount and omni wheels, are designed specifically for Mammotion models. If you’re switching from Dreame to Mammotion, you’ll need to purchase brand-specific accessories. Check our Best Dreame Mower to Buy guide if you prefer to stay with the Dreame ecosystem.
