Our Review

Here is my opinion on the Mammotion Luba mower after 5 months of use:

Setup

I found that following Mammotion's tutorial videos on setup and mapping, accessible from the app, was more useful than the included quick start guide. By doing what the videos showed to do, step-by-step, I had no issues setting up the mower and mapping my zones.

RTK Reference Station and Charging Station Placement

I mounted the RTK reference station using the supplied mounting pole about 10 feet away from the back of my single-story house at the edge of my deck. This was far enough out from the house that it could get a clear view of the sky. I placed the charging station at the same location. The reference station does not need to be in the line-of-sight of the entire lawn. Mine is located behind my house, completely out of view of the front lawn.

Overall efficient cordless mower, I would recommend 100%.

Our Review

This is my 4th year using my 450X, I run it 5 days a week from 8:00AM to 8:00PM although I could set up any schedule I want. I have an 1 ½ which is supposed to be over the limit but it does just fine. I built a little doghouse for it where it will automatically go to recharge and spend the night.

My yard always looks well groomed and my neighbors who have to run their noisey gas hogs every weekend love it also. No gas, no oil, no noise, no maintenance, perfectly reliable. Simply amazing!

Our Review

I purchased my Segway Navimow H800N-VF via Indiegogo, arrived in August. Initially, I faced setup issues but I received a replacement from Segway after a month. 100% satisfied with this mower for almost a month now, as I’m primarily mowing a 1,900 sq ft rear lawn due to concerns about street accidents.

Note: Advertised 8,600 sq ft cutting capacity ideal for flat yards. With hills, it pauses at 70%, takes 3 hours 45 minutes to complete. Mounted GPS antenna on a pole to avoid signal issues. Despite minor hiccups, I would buy it again.

How to Choose a Robot Lawn Mower Without Perimeter Wire

When choosing a robot lawn mower that does not require a perimeter wire, there are several factors to consider to ensure you select the best model for your needs. Here are some key considerations:

Grass Sensors vs. Perimeter Wire

Some robot mowers without a perimeter wire use grass sensors to detect the lawn area and mow it accordingly. This eliminates the need for a physical boundary wire, offering a more seamless and flexible mowing experience.

GPS RTK Technology

Certain advanced robot mowers utilize GPS RTK technology to map out the mowing area without the need for a perimeter wire. This high-precision GPS technology allows the mower to navigate and mow the lawn with accuracy and efficiency.

Mowing Area Size and Complexity

Consider the size and complexity of your mowing area. While some wire-free robot mowers are suitable for small, simple lawns, others are designed to handle larger, more intricate landscapes. Choose a mower that can effectively navigate and mow your specific lawn layout.

Battery Life and Charging

Evaluate the battery life and charging capabilities of the robot mower. Look for a model with a long battery life and efficient charging system to ensure continuous and reliable operation.

Best Robot Lawn Mower Without Perimeter Wire: FAQs

What are the cons of robotic lawn mowers?

Robotic lawn mowers offer convenience, but there are some drawbacks to consider. These may include the initial cost of the mower, the need for regular maintenance, the installation of boundary wires or sensors, and the potential for technical issues or malfunctions.

How deep can you bury the Automower boundary wire?

When installing the boundary wire for an Automower, it is recommended to bury it between 2 to 5 inches deep to protect it from damage and ensure reliable operation. Burying the wire at this depth helps to prevent it from being exposed or damaged by lawn maintenance activities.

What allows a robotic lawn mower to map out the yard?

Robotic lawn mowers use various technologies to map out the yard and navigate the mowing area. This may include GPS, gyroscopes, accelerometers, and other sensors that enable the mower to create a map of the yard and mow in an efficient and systematic pattern.

What is the perimeter wire on a robot lawn mower?

The perimeter wire is a crucial component of a robot lawn mower's operation. It is installed around the perimeter of the mowing area to define the boundaries and guide the mower. The wire emits a signal that the mower's sensors detect, allowing it to stay within the designated mowing area.

How long do robotic lawn mowers last?

The lifespan of a robotic lawn mower can vary depending on factors such as the model, usage, maintenance, and environmental conditions. With proper care and maintenance, a high-quality robot mower can last for many years, providing reliable mowing performance.

Are robot mowers heavy on electricity?

Robot mowers are designed to be energy-efficient, and their electricity consumption is relatively low compared to traditional lawn mowers. The exact energy consumption will depend on the model, mowing area, and mowing frequency, but in general, robot mowers are not heavy on electricity.

Are robotic lawn mowers worth it?

Robotic lawn mowers can be worth it for those who value convenience, time savings, and a well-maintained lawn. While they require an initial investment, they offer benefits such as automated mowing, reduced noise, and emissions, and a consistently manicured lawn.

Do robot mowers cut wet grass?

Most robot mowers are designed to mow dry grass and may not perform as effectively on wet grass. Mowing wet grass can lead to clumping, uneven cutting, and potential damage to the mower. It is generally recommended to avoid mowing wet grass with a robot mower.

What is the major disadvantage of using a robot lawn mower?

One major disadvantage of using a robot lawn mower is the initial cost and installation effort. Additionally, some models may require the installation of a perimeter wire or sensors, and there is a potential for technical issues or malfunctions that may require troubleshooting or repairs.
