Quick Answer: Gardena’s Sileno robot mowers are the budget sibling to Husqvarna’s Automower — both brands sit inside the Husqvarna Group, which invented the robotic-mower category in 1995, and Gardena has been part of that group since 2007. The Sileno Minimo (Consumer Reports’ 2026 pick for small yards, just over $600, up to ~2,600 sq ft) and the newer Sileno Flex ($599.98 at Home Depot, up to 0.2 acre) anchor the 2026 US lineup. The trade-off: every current Sileno sold in the US is still boundary-wire only — Gardena’s wire-free Sileno Free has launched in Europe but not yet in America.
If you’ve seen a Gardena Sileno recommended as the “cheaper Husqvarna,” that reputation is earned — and it’s more literal than most brand comparisons on this site, since the two companies are the same corporate parent. Here’s what that actually buys you in 2026, and where it falls short of newer wire-free rivals.
A Husqvarna Group brand since 2007
Gardena started in 1961 in Ulm, Germany, founded by Werner Kress and Eberhard Kastner as a garden-tool maker, long before robot mowers existed. Husqvarna Group acquired Gardena in 2007, folding it into the same Swedish parent company that, in 1995, built the original Solar Mower — the machine that created the robotic lawn mower category. Today Husqvarna Group sells robot mowers under four brands: Husqvarna, Gardena, McCulloch, and Flymo, with Gardena positioned as the accessible, garden-tool-store-friendly name and Husqvarna as the premium, dealer-serviced flagship.
That shared parentage is the whole story of what a Sileno is: not a knockoff or a rebadge from a different factory, but the same engineering lineage sold at a lower price point and through different retail channels — Home Depot and Amazon instead of a Husqvarna dealer network.
Gardena Sileno 2026 lineup at a glance

Confirmed 2026 US pricing: the Sileno Flex lists at $599.98 at Home Depot, and the Sileno Minimo runs just over $600 per Consumer Reports’ 2026 testing. City and Life pricing varies more by coverage variant and retailer promotion — check current listings before buying.
1. Gardena Sileno Flex — Best Overall
Gardena Sileno Flex
- Covers up to 8,600 sq ft (0.2 acre) — Gardena's widest coverage in the current US Sileno line.
- 1–4 inch cutting height range, the widest adjustment span in its class, per Gardena's own specs — useful for mixed grass types or a lawn that's been let go a week too long.
- Rated for slopes up to 35%, in line with the rest of the Sileno line.
- Bluetooth app control, SensorControl adaptive scheduling; boundary wire required, no RTK or GPS.
- Lists for $599.98 at Home Depot, occasionally discounted further with a store card promotion.
Setting up a boundary-wire mower for the first time usually means an afternoon of trenching and staking before the first cut even starts — start a free Audible trial and queue up something to listen to while you lay the wire around flower beds and trees.
The Flex is the clearest “best overall” Gardena in 2026: at $599.98 it undercuts most wire-free rivals by hundreds of dollars while covering a genuinely useful 0.2 acre, and its 1–4 inch height range handles more grass types than the narrower-range City or Minimo. The catch is the same one that applies to the whole brand — no wire-free option yet in the US. If skipping the trench matters more than price, compare it against our robot lawn mower without perimeter wire guide before buying.
2. Gardena Sileno Minimo — Best for Small Yards (Consumer Reports’ Pick)
Gardena Sileno Minimo
- Consumer Reports named the Sileno Minimo its top robotic lawn mower for small yards in 2026, covering up to roughly 2,600–2,700 sq ft.
- Three mowing-height settings and a passcode safety lock to prevent accidental starts, per CR's testing notes.
- Rated among the quietest in its class at roughly 57 dB(A), per Gardena and Amazon's listing — see our full [quietest robot lawn mower](/best/quietest-robot-lawn-mower/) rankings for how that compares brand to brand.
- Honest caveat: 3.6 out of 5 stars on Amazon, with recurring owner complaints about a finicky wire install, occasional getting stuck, and irregular cutting patterns.
For a small, fenced, relatively simple lawn, the Minimo is the rare budget robot mower with a genuine third-party win behind it rather than just marketing copy. It’s not flawless — CR and Amazon reviewers agree the wire install takes patience and the mower can wander on complicated layouts — but at just over $600 for a Consumer Reports small-yard winner, it’s hard to beat on value.

Gardena vs. Husqvarna Automower — same parent, different price
Because Gardena and Husqvarna share the same Swedish parent company, the comparison isn’t “which brand is more trustworthy” so much as “how much are you paying for the Husqvarna name and dealer network.” Husqvarna’s Automower lineup runs from boundary-wire entry models to wire-free RTK GPS flagships like the 430X and 450X, sold through a dealer-service network with professional installation available. Gardena’s Sileno line stays boundary-wire only, sells through Home Depot and Amazon instead of dealers, and costs less at every comparable coverage tier. See our full Husqvarna Automower guide for the premium side of the same family tree, or our Husqvarna Automower vs. Worx Landroid comparison for how the flagship stacks up against a completely different brand.
Gardena Sileno vs. the wire-free competition
Gardena’s biggest gap in the US market is navigation tech. Every Sileno model sold here in 2026 still needs a buried perimeter wire, at a time when Segway Navimow, Mammotion, and Kress have all shipped wire-free RTK GPS models that map a lawn from a single walked perimeter. Gardena does sell a wire-free Sileno Free in Europe starting in 2025 (from 1,499.99 euros), but it has not launched in the US as of 2026. Until it does, Gardena’s advantage stays squarely on price and Husqvarna-family engineering, not navigation convenience — if wire-free is a hard requirement, see our dedicated robot lawn mower without perimeter wire guide instead.
Gardena Sileno by the numbers
- 1961: The year Gardena was founded in Ulm, Germany, as a garden-tool maker — decades before robot mowers existed.
- 2007: The year Husqvarna Group acquired Gardena, making it a sibling brand to Husqvarna Automower rather than a competitor.
- 1995: The year Husqvarna Group’s original Solar Mower created the robotic lawn mower category — the shared engineering root behind every Sileno sold today.
- Just over $600: Consumer Reports’ cited 2026 price for the Sileno Minimo, its top pick for small-yard robot mowers.
- 0.2 acre (~8,600 sq ft): The Sileno Flex’s max rated coverage, the largest in Gardena’s current US lineup.
- 57 dB(A): Gardena’s approximate noise rating across the Sileno line, among the quietest tier we track alongside the Segway Navimow’s 54 dB(A).
The bottom line
Gardena’s Sileno line is exactly what its Husqvarna Group parentage suggests: the same category-founding robotic-mowing engineering as the Automower, sold cheaper and through mainstream retail instead of a dealer network. The Sileno Minimo is a genuinely credentialed small-yard pick backed by a Consumer Reports win, and the Sileno Flex covers a useful 0.2 acre for under $600. What Gardena isn’t, in the US as of 2026, is wire-free — every current model still needs a buried perimeter wire while rivals move past it.
