  • ECOVACS GOAT A1600 RTK: The innovative robotic lawnmower without boundary wire in the test

    A robot mower without boundary wire, with a grey and white casing, moves from a brick patio onto a green lawn bordered by stones and gravel. www.commaik.de

    A robotic lawnmower without boundary wires can revolutionize lawn care – no more laying and repairing wires, just precise navigation with RTK technology. The ECOVACS GOAT A1600 RTK promises exactly that. After more than 10 years with the Gardena Sileno+, which was regularly slowed down by broken cables, we needed an alternative. In this test, I show how the GOAT A1600 RTK performs in practice: from installation and mapping to mowing quality and safety. Is the cordless robotic lawnmower really convincing? Here is the answer.

  • Installing a lawn sprinkler: Step-by-step instructions for watering your garden

    A person holds a trencher, creating trenches in a grassy yard for irrigation. Several orange buckets filled with soil are placed around the dug areas, with a brick path on the right and a stone building in the background. www.commaik.de

    Installing lawn sprinklers and setting up efficient lawn irrigation – that’s exactly what this article is about. I show how I planned my garden irrigation system, laid the PE pipes and equipped the system with automatic irrigation. I explain step by step how to excavate the trenches, connect the sprinklers with Hunter Swing-Joints and test for leaks. In the end, the irrigation runs reliably and saves time when watering.

    A pair of secateurs lies on a wooden board and cuts a branch in the midst of green plants and flowers in a sunlit garden, with a bench and a house in the background. www.commaik.de

    High-quality secateurs are essential for the care of plants, shrubs and trees. But which secateurs are the best? In my large garden shears test, I tested various models and compared them with each other. I took a close look at both bypass pruning shears and anvil pruning shears to find out which are best suited to different applications. Whether you want to cut fine branches, thick twigs or dry wood – in this garden shears comparison you will find the best models for every requirement.

  • Laying the water pipe in the garden: tips for connecting the water supply to the garden irrigation system

    Open trench in a paved area with exposed cables, pipes, and a water pipe in the garden, surrounded by loose soil, bricks, and paving stones—signs of ongoing underground utility or lawn irrigation work. www.commaik.de

    Laying a water pipe in the garden is a crucial step for efficient garden irrigation and reliable lawn watering. In this project, the pipeline had to be routed under an existing cobblestone path. The paving stones were removed, a trench dug and the pipes laid together with empty conduits for control and power cables. In addition to the right choice of material, frost resistance also plays an important role. The entire process – from planning and leak testing to restoring the sidewalk – is described in detail in this article.

  • Installing lawn irrigation: Valve box, Hunter solenoid valves and Rain Bird water distribution in detail

    Lawn irrigation system components, including pipes, valves, and wiring, are laid out on the ground next to an open valve box in a grassy area. A green garden hose and plastic cover are also visible. www.commaik.de

    Efficient lawn irrigation starts with a well-planned valve box, which forms the heart of the entire garden irrigation system. In this article, I will show you how I set up my valve box, selected the right components and optimized the water distribution. This involves installing the manifold, connecting the Hunter solenoid valves and laying the pipes safely. I also explain why I rely on a modular design so that the system can be flexibly expanded at any time. All the details on material selection, pressure resistance and optimum connection technology can be found here.

    Robotic lawn mowers without boundary wires make lawn mowing smarter and more flexible. Instead of perimeter wire, they rely on GPS, RTK navigation and camera technology – this saves installation effort and offers more precise control. My detailed comparison shows which models are convincing in the test, where the strengths and weaknesses lie and which robotic mower is best suited to which garden conditions.
