Anyone with a small, flat lawn who wants to spend as little as possible on a robot will come across two boundary-wire models. The Husqvarna Automower Aspire R4 from Husqvarna Group cost PLN 1,999 (≈ EUR 460) on promotion on 10 October 2026, and the GARDENA SILENO minimo 500 m² from GARDENA PLN 2,299 (≈ EUR 525). On paper they are near twins: a 16 cm disc, 20–45 mm cutting height, slopes up to 25%, about 70 minutes of mowing and 75 minutes of charging. The differences lie in the details: rated area, noise, how you control the robot and what comes in the box. For anyone who does not need satellite navigation and is happy to lay a wire, those details will decide the choice.

Design and specifications
Both robots work inside a physical boundary wire and have neither satellite navigation nor obstacle detection. Both have a lift sensor. Husqvarna adds a tilt sensor, GARDENA a frost sensor that pauses mowing when temperatures approach freezing. A three-blade disc cuts a 16 cm swath, and height is set between 20 and 45 mm, by hand on the Aspire R4. Both handle slopes of up to 25% inside the lawn and 10% along the wire.
The Aspire R4 weighs 5.9 kg and has a 2 Ah battery; the SILENO minimo weighs 6.1 kg. Both are IPX5 and neither has a display. Both makers state noise the same way, as perceived noise in dB(A): 59 dB(A) for the Husqvarna and 57 dB(A) for the GARDENA. GARDENA describes the minimo as the quietest in its class. It also has CorridorCut, which takes the robot through passages 60 cm wide.
Price and availability in Poland
On 10 October 2026 the Aspire R4 cost PLN 1,999 (≈ EUR 460) gross in Husqvarna's Polish online shop. That is a promotional price; the regular price is PLN 2,799 (≈ EUR 640). The SILENO minimo 500 m² cost PLN 2,299 (≈ EUR 525) gross in GARDENA's Polish online shop that day, with no promotion noted. Both were in stock. Once the promotion ends, the Husqvarna becomes the more expensive of the two.
The GARDENA kit contains 150 m of boundary wire, 150 pegs and 3 m of low-voltage cable. You install it yourself or pay someone to do it. For the Aspire R4 we have no description of the box contents, so before buying check how much wire you get and whether you need to buy more. With either model, allow time to lay and peg the wire around the lawn. Cheaper and pricier alternatives, including wire-free ones, are listed in “Robot lawn mowers”.
Which model for which job
Both models are meant for a small, flat gardens. A 10% limit along the wire means the edge of the lawn should not run along a bank.
The Aspire R4 covers up to 400 m². It has the edge in connectivity: the Automower Connect app works over Bluetooth and Wi-Fi, and the robot also has buttons. Husqvarna lists its limitations: no display, no object detection and no option for GPS theft tracking.
The SILENO minimo covers up to 500 m², and CorridorCut lets it pass through narrow links between parts of the lawn. Set-up and scheduling run through the GARDENA Bluetooth app within 10 m, with no remote access over the internet. The frost sensor pauses work when temperatures approach freezing. The lower noise level helps when neighbours live close by.
Conclusion
The Automower Aspire R4 and the SILENO minimo 500 m² are near twins: boundary wire, 16 cm disc, 20–45 mm cutting height, slopes up to 25% (10% along the wire), about 70 minutes of mowing and 75 minutes of charging. The Husqvarna covers up to 400 m², connects to its app over Bluetooth and Wi-Fi, and cost PLN 1,999 (≈ EUR 460) on promotion on 10 October 2026 (regular PLN 2,799 (≈ EUR 640)). The GARDENA covers up to 500 m², is quieter on the same measure (57 against 59 dB(A)) and has CorridorCut and a frost sensor, but its app works only over Bluetooth within 10 m. It costs PLN 2,299 (≈ EUR 525). On promotion the R4 is cheaper; a larger lawn favours the GARDENA.
Lawn of up to 400 m², Wi-Fi connectivity and the lowest price right now: the Husqvarna Automower Aspire R4, as long as the PLN 1,999 (≈ EUR 460) promotional price applies.
Lawn of 400 to 500 m², narrow passages, neighbours close by: the GARDENA SILENO minimo 500 m². It covers a larger area, is quieter on the same measure and comes with wire and pegs in the box.
If the Husqvarna goes back to PLN 2,799 (≈ EUR 640), the GARDENA will be cheaper and cover a larger lawn, leaving the Aspire R4 with Wi-Fi as its main advantage. If the lawn has a bank at its edge or slopes above 25%, both are out, and you should look for a model with a higher slope rating in robot lawn mowers. In short, both are simple and cheap, and the choice comes down to lawn size and how you want to control the robot.
