The Tertill Garden Weeding Robot is great in covering its specified area of around 200 square feet. If you are someone who hates the process of weeding and would like to cut time, then the device will be a great option.
The Tertill, like a Roomba for weeds, has multiple features such as weather resistance and clean energy to help maintain the weeding process in any season.
It can even be connected to the smartphone app through Bluetooth for better control.
However, I would not recommend the Tertill for larger gardens, as it will not be able to accommodate such areas.
Also, if you are a keen gardener, you’d probably rather stick to weeding yourself, but for its price, the Tertill Weeding Robot can be a valuable gardening companion that will be suitable for those that just want a little help.
- Greatly Saves Time
- Low Ongoing Costs thanks to Solar power
- Gentle with Plants
- Has problems with very low weeds
- Terrain can affect maintenance frequency
- Small coverage
As seen on the pros and cons, the advantages win the match. Yes, the Tertill Weeding Robot may not be able to cover a large area, but this functionality is proportional to its cheap price.
Also, the issue concerning the terrain is optional since not everyone has very complicated garden bed layouts. Overall, the time that this robot can save is unmatched, and maintaining it can be a good activity not only for you but also for your kids.

Full Tertill Garden Weeding Robot Review
How solar-powered weeding robot works
Unlike many garden robots, the Tertill does not require any power outlet, as it is solely powered by the Sun’s energy. The device is placed on an enclosed area in the garden that is surrounded by plants and weeds.
The robot has a weed whacker at its bottom which turns on every time a weed is detected under the bumper through the sensor. Once the presence of objects is detected, the weed is cut immediately.
Another way that the Tertill Weeding Robot works are through its wheels. As it moves around, the wheels scrape the ground slightly to kill possible weed seeds that are on the ground’s surface before they even emerge.
The device uses Capacitive Sensing Technology which it senses the capacitance of slightly conductive materials such as weeds, plants, or fences. Different materials each have their own conductivity, and the Tertill uses these values to determine whether to avoid or cut what is in front or underneath it.
It also uses height sensor technologies to identify the difference between plants and weeds. As we all know, weeds are significantly shorter, so if the Tertill Weeding Robot passes under the robot’s shell, the cutting protocol is initialized.
If you have baby plants in your garden bed, there is no need to worry as plant collars are available to protect them.
Recharging of the robot is never a problem since the Tertill Weeding Robot uses a solar-powered energy source. It also automatically configures the process in such a way that weeding patrols are scarcer when cloudy weather is present.
The Tertill is great in weeding, and it does not need much power to finish its task. The grooved sideway wheels never get stuck even in wet dirt or soil, and the plastic case of the robot is built to withstand hot or cold conditions. You can even water the garden bed as the robot weeds it, as it is built to accommodate water thanks to its weather-resistant technology.
The robot does not touch any of your plants thanks to the sensors that are placed all around it. It works like the touch response in our smartphones, but this is not created for human hands, but tall plants in your garden. This way, it still performs well in cutting the weeds placed on the garden landscape without harming your beloved plants.
What sets this robot apart from others in terms of performance is that it does need self-docking to recharge. Instead, it can just lay in your garden and wait for the sun to show so that it can proceed to gain energy. Once the battery is filled up, it will go back to its usual routine of clearing weeds in the garden.
One of the main limitations of the robot is that it needs an enclosed area to operate. Thus, there is a need to put up a fence or any sort of barrier around your garden to avoid the robot from wandering outside. The good news is that a minimum of 4 inches is enough to keep the Tertill at bay.
In terms of area coverage, the small robot can only do so much. It can handle up to 200 square feet of the garden area and nothing more, as it is designed for smaller garden sizes. While this might not be a large space, it is a common garden size for casual gardeners.
Another limitation that the robot has is that a specific garden layout is necessary for its optimal use. This layout specification is included upon the purchase of the product, and it includes the position of the irrigation hose, distance of the plants from each other, and distance of the vegetation from the fence. This can be a bit jarring especially for garden owners who have a compact area with not a lot of space.
The presence of many rocks in the vicinity can also affect the frequency of maintenance, some particles may get stuck under the weed whacker or wheels. Thus, owners must remember to check on the robot occasionally to help it perform better in the long run.
Ease of set up and use
The first step to do when using the Tertill is to make sure that you have a physical boundary or barrier to define the robot’s working area. Wood or conductive materials such as wires are recommended. On the other hand, plastics are discouraged as it causes problems on the Capacitance Sensors.
There might be a need to weed the garden at least once before proceeding to use the robot, as long patches of weed might interfere with the system. Programming of the Tertill is not necessary, and all you need is to put the robot in the middle of the garden and then press the button to initiate the robot’s operation.
Small plants should be provided with row guards or plant guards so that the robot will avoid them. The top of the guard should be in line with the top of the plant to guarantee that the robot will easily sense it.
The recommended distance for plants is 12 inches apart, and you should make sure that slopes in your garden are not more than 6 degrees. Once a steep elevation is detected, the robot will simply turn around and ignore the area.
One might need to watch out for ruts or holes that might interfere with the robot’s operation, as it can fall in these places. A good tilling or clearing session might be necessary to smoothen the garden area.
Hoses also need to be placed a bit buried on the ground so that the robot does not bump. Once all these cautions are secured, the use of the robot will be straightforward and easy.
The device is very reliable in its operation. It features a non-stop working system wherein it can stay in your garden even if it is recharging. Thus, there is no need for any homeowners to take the Tertill away from its designated garden area, landscape, or backyard.
The robot can also be connected through your smartphone using the App. Its main mode of connecting is Bluetooth, and this is a very accessible way to manage the device.
However, remote controls are non-existent, and you only get to view the Tertill’s status in terms of battery, temperature, and charging status. You can also check for firmware updates for better features from time to time.
While the lack of remote-control access might seem to be a disadvantage, it does not really matter that much as the Tertill is designed to be fully autonomous. All you need to do is to place the robot in the garden and it will do its job masterfully.
There are some issues regarding the robot being stuck on holes or medium rocks, but this is not a problem for those who set up their garden in the correct manner.
Wheels and Case
Some maintenance for the garden weeder robot involves cleaning the wheels and the unit especially when rainy weather is present.
Mud may get stuck in between the wheels, and there might be a need to clear them off using a brush or scraper if the movement of the Tertill is impeded. To care for the case, a cloth is necessary.
Remember to not use water to spray the underside of the weed-cutting robot as this may cause problems for the circuitry.
Another maintenance job that you need to do is the replacement of the whacker string. When you notice that it has shortened by an inch, then you should do these steps.
First, push the string into the hub with your fingers or pull it at the back using pliers. Then, you need to install the new strings by reversing the process that you just did. The string will be in place once the black film is all the way down the designated slot.
Extra Purchases and ongoing costs
Additional purchases for the device include Plant Guards and Row Guards (for protecting small plants) and whacker replacement kits.
These can be bought at the official store for $25 or less. As for the main product, some bundles include seeds or stickers to make the Tertill more kid-friendly. You may notice that some of these prices may be higher than the initial $350 cost of the product.
The garden weeder does not need ongoing costs as even electricity bills are canceled thanks to Solar-powered technology. The unit will save you a lot in the long run as the Tertill does not draw power from your electrical outlets.
How do you keep the unit from running off to the lawn?
A physical barrier such as a fence is required to keep the Tertill in its assigned area. You can use various materials like wood, wires, or electric barriers for this. No need to worry, it only needs a minimum of 4 inches for the length of the boundaries.
Can the device deal with weeds in concrete floors?
The answer to this question is no since the theTertill is only designed to deal with weeds that are in the dirt or soil. It has no features to cater to concrete floors, as the whacker string works best with the land.
When do I need to pick the Tertill weeding robot up?
Tertill only needs to be picked up during cleaning times. Other than that, you can leave the bot in your garden 24/7. The Tertill does not need to be plugged into a wall socket thanks to the solar-powered panels attached to the robot which uses sunlight to gain energy.
How do I connect to the app?
First, you need to download the Tertill app on your smartphone by going to the Playstore for Android devices or AppStore for iOS devices. Then, you need to connect the Tertill through Bluetooth and pair it with your device.
Will it climb hoses placed in my garden?
Yes, it does well with climbing hoses. However, gardeners need to make sure that the hose is laid flat on the ground by digging a bit so that it does not produce a high bump when the Tertill runs over it.
The Tertill Garden Weeding Robot can be considered as a very helpful technology for all your weeding needs. Like any other home robot companion, it serves well in automating the weeding process without the need for human intervention.
The Solar Power technology paired with an entry-level price makes it a bang-for-the-buck device worthy of your admiration. Say hello to more precious time with your beloved plants if you decide to get this robot for your house or home garden.
