Husqvarna Aspire R4

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.

Husqvarna's wired small-garden Automower: a 400 m² boundary-wire robot with a 16 cm cut, the lightest body in our robot set at 5.9 kg, and a 59 dB(A) rating.

The Aspire R4 is the boundary-wire member of Husqvarna's entry-level Aspire pair — the wire-free R6V we also list is its sibling. Husqvarna rates it for 400 m² with a 25% slope limit, a 16 cm cut and a 20–45 mm height range. At 5.9 kg it is the lightest robot in our catalogue, and its 2 Ah battery is quoted at about 70 minutes of mowing against a 75-minute recharge, with IPX5 sealing, a 59 dB(A) rating, app control and anti-theft protection.

Two comparisons frame it. Against its own R6V the wired R4 costs less (an £849 RRP), cuts narrower (16 cm against 22 cm), covers less (400 against 600 m²) and needs the perimeter cable laid — in return for the positional certainty of a wire and no dependence on satellite or camera visibility. Against Gardena's wired SILENO minimo 250 the spec sheets are near-identical — 16 cm cut, 20–45 mm, a 25% slope, around 70 minutes per charge — with the R4 rated for a larger 400 m² area and 0.2 kg lighter, but 2 dB(A) louder and slower to recharge (75 against 60 minutes).

Verification note: Specs are quoted from Husqvarna's Irish product page. The £849 is the RRP as labelled by a UK dealer, with that dealer's discounted sale price excluded; at capture Husqvarna's own UK and Irish pages showed the model as discontinued with no price displayed, so check availability before buying. Warranty and multi-zone support are not stated and are left unspecified. This is a reading of the published specification, not a hands-on test.
