Gardena Sileno minimo (250 m²)

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.

The entry point to Gardena's SILENO line: a wire-guided robot rated for 250 m², lighter than the Sileno city but with a lower slope limit and Bluetooth-only control.

The SILENO minimo 250 is Gardena's small wire-guided robot, rated for 250 m² ± 20% and supplied with a 150 m boundary cable — so it needs the usual perimeter-wire installation rather than the antenna-and-satellite setup of the wire-free generation. Gardena publishes a 16 cm cutting width, a 20–45 mm height range, 6.1 kg, IPX5 sealing and 57 dB(A), with roughly 70 minutes of mowing per charge against a 60-minute recharge. It is rated for 25% slopes inside the working area and 10% at the boundary wire, and Gardena states it will thread a 60 cm passage.

Against its own sibling the trade-offs are specific rather than generational. The minimo is 1.2 kg lighter than the Sileno city 250 and matches it on noise at 57 dB(A), but the city takes steeper ground — 35% against 25% — and cuts up to 50 mm rather than 45 mm, so the smaller machine is the more limited one on banks and in longer grass. Control is over Bluetooth rather than Wi-Fi, which means scheduling from beside the mower rather than remotely; Gardena's 'smart' SILENO variants are the ones that add app access from away. Warranty is two years, extended to three on registration.

Verification note: Cutting width, cut heights, weight, runtime, recharge and IPX rating are quoted from Gardena's Australian product page; working area, both slope figures, noise, the 60 cm passage and Bluetooth control are confirmed on Gardena International. A German robot-mower portal independently corroborates the cut width, heights, weight and runtime, but states a 75-minute recharge against Gardena's 60 — the manufacturer figure is used here. Gardena publishes no RRP on its international, UK or Australian sites, and observed street prices vary too widely to quote a standard figure, so no price is shown. Battery voltage and capacity are not published by Gardena and are left unspecified. This is a reading of the published specification, not a hands-on test.
