What Makes a Good Robot Lawn Mower for Hills?

1. Slope

Always check how the model handles different slopes and gradients. Depending on how your lawn is designed and its inclination rate, you have to go for a lawn mower that is rated to meet that specific inclination percentage or degree. 

Further, you can always check online slope calculators to help you determine the slope of your garden if you aren’t sure.

2. Wheel Design

You have to also consider the wheel design in terms of the number of wheels, size, and overall traction. When mowing a sloping lawn or garden, a four-wheeler is always better than a two-wheeler. They give better balance, grip, and traction on inclined areas. 

To handle raised areas, the wheels will need more power and torque. This means that they will face less resistance moving uphill. 

Wet weather can also play its part too – wetter surfaces can reduce the overall performance level. Always take this on board if testing models in wet conditions.

3. Drive Motor

Ultimately, a more powerful lawn mower motor offers better performance. Again, you have to pick a mower equipped with a motor that meets the demands of your garden or lawn. 

The motor’s power determines how effective your lawn mower will be when trying to maneuver and climb hills. It also covers how they maintain traction and cut the entire lawn area. Generally, steep slopes and hills require more power than flat surfaces so consider that when making your choice.

4. Area Coverage

Before you rush off to choose a lawn mower, it is important to pay attention to the important features that will serve your space best. After all, you don’t want to invest in a tool that ends up not getting the job done. 

This is even more important for robot lawn mowers than regular ones. That's because you have to consider how much power it has. Too much power is counterproductive in small, cramped areas.

Alongside that, the shape and size of the garden may affect the mowing patterns themselves. Anything that has an awkward shape could cause an uneven cut if not configured properly.

Therefore, always calculate the dimensions of your space and compare them against the lawn mower model you are interested in.

5. Features

Robotic lawn mowers often come with additional features that help enhance their functionality.

Some lawn mowers offer condition reports such as weather detection to prevent further damage. Others can sync directly with other smart devices to allow easier operation and guidance. This means that they will allow you to remotely operate them or set mowing schedules from anywhere.

Some robot mowers pair with smart systems such as Google Assistant and Amazon Alexa to allow full voice control from inside your home.
