How can the Gardena SILENO sense cover 600 m² with only 40 minutes of mowing per charge?

By mowing little and often. Gardena rates the GARDENA smart SILENO sense for 600 m² and quotes about 40 minutes of mowing per charge, so the rating assumes many short sessions spread through the day, with trips back to the charging station in between. Gardena doesn't publish the charge time on its UK page, which makes it hard to work out how many sessions fit into a day.

Two other limits squeeze the working window. The mower relies on its camera, and Gardena says it needs daylight, so night-time runs are off the table. And the cut is 160 mm wide, which means more passes to cover a given area than a wider-deck mower.

Put together, the 600 m² figure is best read as a ceiling for a simple, open lawn with a generous daytime schedule. Gardena also states its area ratings with a tolerance of plus or minus 20%. For lawns of about 500 m² or less, the sense fits comfortably. For something closer to the limit, or a garden with lots of beds and corners, look at a model with a longer run time, such as the GARDENA smart SILENO free, which Gardena says mows for about 140 minutes per charge.
