What size lawn is the Gardena SILENO city really suited to?

The GARDENA SILENO city sold new in the UK is rated for 500 m², but it's most comfortable on lawns of up to about 400 m². Gardena states its area ratings with a tolerance of plus or minus 20%, and the figure assumes a simple, open lawn.

Two things eat into that rating in real gardens. First, the cut is narrow at 160 mm, so the mower needs many hours to cover the ground. Gardena quotes about 65 minutes of mowing per charge followed by roughly an hour on the charging station. Second, every narrow passage, island bed and awkward corner adds time, because the mower has to find its way in and out of each one.

You'll also see older 250 m² SILENO city models, smart and non-smart, as old stock or second-hand. Gardena lists those as legacy products and no longer publishes their specifications.

If your lawn is over about 400 m², look at the GARDENA SILENO life, which has a wider cut and larger ratings. Our lawn size tool helps you measure the area first.
