The spec-sheet read

Our analysis of the sourced spec sheet — positioning and trade-offs, not a hands-on review. We don't score mowers we haven't tested.

Gardena's compact wired city robot for 250 m²: a 35% slope rating that only the Worx Landroid M500 Plus matches among the small wired machines here, 57 dB(A), and the CorridorCut narrow-passage mode.

The Sileno city 250 is Gardena's wired robot for small urban lawns, rated for 250 m² with a 35% slope limit — steeper than the 25% of both the SILENO minimo and the Husqvarna Aspire R4 that compete at this size. It cuts across a 20–50 mm height range, is quoted at 65 minutes of mowing against a 75-minute recharge, and carries IPX5 sealing at 7.3 kg with a 57 dB(A) rating, app control and anti-theft protection. Gardena's CorridorCut function lets it work through narrow passages between lawn sections.

Its natural comparison is with Gardena's own SILENO minimo 250, which we also list: the minimo is 1.2 kg lighter and matches the city on noise, but the city takes steeper ground and cuts 5 mm higher at the top of the range, so on a banked or longer-grass small lawn the city is the more capable of the two. The record has two gaps worth knowing: Gardena does not publish a cutting width for this model, and no standard price could be confirmed — the base city 250 was listed as discontinued or on promotion by every retailer checked, often with the separate 'smart' Wi-Fi variant substituted.

Verification note: Specs are quoted from GARDENA's international product page and cross-checked against an independent specification listing. Cutting width and battery capacity are not published by Gardena and are left unspecified. No price is shown because only promotional, discontinued or wrong-variant ('smart') figures were found at capture. This is a reading of the published specification, not a hands-on test.
