  • Preparing Your Robotic Lawn Mower for Winter: Properly Storing the Battery, Charging Station, and RTK for the Winter

    A robotic lawn mower parked on its charging station in a lawn, ready to be prepared for the winter months while you store it for the winter. www.commaik.de

    To me, winterizing a robotic lawn mower means more than just turning it off and storing it away. Using the ANTHBOT M9 PRO as an example, I’ll show you how I clean it, change the blades, and care for the battery so the robotic lawn mower can stay protected over the winter. I’ll also address the questions that come up every year: Does the charging station need to be dismantled? Does the RTK antenna stay outside? And when does the battery need to be recharged? I’ll explain my approach, highlight differences compared to other models, and show what I look out for when storing it for the winter and when…

  • Winterizing Your Pool: Drain the Water, Store the Equipment, and Cover the Pool

    A rectangular swimming pool that has been prepared for the Pool Winterfest: It is covered with a gray tarp secured to a stone terrace with blue water hoses. www.commaik.de

    To winterize my pool and protect the equipment from frost, I cleaned the pool, backwashed the filter, and lowered the water level. I also moved the BAYROL dosing system and other components to the basement for the winter. I’ll describe my process, including how I stored the sensors in a humid environment and how I protected the pipes. New this time was the winter cover with aluminum struts and water bags: it was meant to solve the problems I’d had with my previous tarp and pool cushions.

  • Variable-Frequency Drive for a Pool Pump: Installation, Settings, and Saving Electricity

    A swimming pool in the backyard with patio furniture and text indicating a 52% savings thanks to a variable-frequency drive. www.commaik.de

    Retrofitting a variable-frequency drive to my pool pump, regulating the speed, and saving electricity in the process—that’s exactly what I did with my SPECK BADU Magic II 8. With the AquaForte Vario+ II, the daily energy consumption of the pump and UV-C lamp dropped by about 43 percent, and at the same time, the system became significantly quieter. I’ll show you how I installed, connected, and configured the variable-frequency drive, what the measured values were, and why the lowest speed wasn’t the best choice in the practical test. I’ll also cover operating times, costs, and the requirements for a suitable retrofit.

  • High Chlorine Consumption in the Pool: Why 20 Liters of Chlorine Disappeared in Two Weeks

    An almost empty swimming pool with some dirt on the bottom, a green hose, and a small pump. A staircase leads down to the pool, which is surrounded by light-colored tiles—factors that can affect chlorine usage when you’re preparing the pool for use. www.commaik.de

    Too much chlorine in the pool, a chlorine canister that’s constantly empty, or water parameters that don’t add up even though the water is clear: There are many possible causes for high chlorine consumption. In addition to sunlight, temperature, and swimming activity, the pH level, the chlorine products used, and cyanuric acid also play an important role. Even a good redox value does not automatically mean that the measured chlorine level in the pool is interpreted correctly. I noticed the problem after installing the BAYROL Automatic Cl-pH. In just under two weeks, the dosing system used about 20 liters of liquid chlorine—even though the water was clear and the system…

  • TerraMow V1000, V600, and Mini 500 Review: Robotic Lawn Mowers Without RTK and Lidar?

    Two robotic mowers, the TerraMow V600 and the V500, are sitting on the lawn; cameras are mounted on their sleek gray bodies and wheels. The word “TERRAMOW” is clearly visible on both of them. In the background, you can see a hedge and a building—the perfect setting for an outdoor test. www.commaik.de

    A robotic lawn mower without RTK, LiDAR, or a boundary wire is supposed to map the yard on its own and still navigate reliably. This is exactly where the TerraMow Mini 500, TerraMow V600, and TerraMow V1000 come in, with their camera-based TerraVision 2.0 technology. I’ve tested the Mini 500 and V600 extensively and am comparing them to the larger V1000. This article highlights the differences in navigation, obstacle detection, the app, coverage area, and edge cutting—and explains which model is the best choice for which type of garden.

  • ECOVACS GOAT O1200 LiDAR PRO Review: Perfect Edge Mowing Without Any Touch-Ups?

    An Ecovacs Goat robotic lawn mower with a black-and-white body stands in the sunlight on a green lawn; it has a red button and a front brush. www.commaik.de

    Lawn edges are among the biggest weak spots for many robotic mowers. The open lawn area is mowed neatly, but a narrow strip often remains unmowed along walls, hedges, or barriers that the mower cannot cross. That’s exactly where the ECOVACS GOAT O1200 LiDAR PRO comes in, with its side-extending TruEdge Trimmer. I tested the robotic lawn mower on three separate lawns, evaluating features such as automatic mapping, navigation, app control, the mowing pattern, and edge cutting. I was particularly interested in whether the built-in trimmer could actually reduce the need for regular touch-ups with a handheld trimmer. The first impression in the ECOVACS GOAT O1200 LiDAR PRO review was…
