There, the 5 Ah battery was recharged to 90 percent in just over an hour, so that it was quickly back on the lawn to continue the work. Around 70 Wh went into the battery. We measured the standby consumption, i.e. when the robot is waiting in the charging station with a fully charged battery for the next use, at around 4 W.
We evaluate the energy efficiency of the robot mowers we test based on the assumption that a 500 square meter area is mowed three times a week. This is somewhat more difficult with this test candidate due to the chaotic approach. Roughly extrapolated, this results in approx. 7 kWh per month, although complete coverage and accuracy cannot be guaranteed. Overall, the energy requirement is therefore limited, although a systematically navigating robotic lawnmower is definitely more efficient.
We measured the noise level at around 55 dB, although this also depends on the mowing activity. Overall, the RoboUp Raccoon 2 SE was pleasantly quiet in the test, making it an unobtrusive garden helper for small city gardens.
