Quick Answer: Gardena and Husqvarna are sibling brands under the same parent — Husqvarna Group, which invented the robotic mower category in 1995 and acquired Gardena in 2007. The Gardena Sileno Flex covers up to 0.2 acre for $599.98 at Home Depot but still needs a buried boundary wire, while the Husqvarna Automower 420 iQ covers 0.5-1 acre for $3,499.99 using wire-free EPOS satellite navigation and carries a 4-year unit warranty plus a separate 3-year battery warranty, per Husqvarna. Buy Gardena for the lowest price in the family; buy Husqvarna for wire-free installation, bigger coverage, and a longer warranty.
Most brand-vs-brand comparisons pit two genuinely independent companies against each other. This one doesn’t — Gardena and Husqvarna are both owned by Husqvarna Group, so the real question isn’t which engineering is better, it’s how much the Husqvarna name and wire-free tech are worth over Gardena’s budget pricing.

The Flex undercuts Husqvarna’s cheapest wire-free model by nearly $2,500, but it’s still boundary-wire, and its 0.2-acre ceiling means it’s only realistic for a small-to-mid suburban lot. Full lineup in our Gardena Sileno review.
Husqvarna: wire-free navigation, bigger coverage, longer warranty
Husqvarna Automower 420 iQ
- Covers 0.5 to 1 acre using wire-free EPOS satellite navigation — no buried perimeter wire, per Husqvarna.
- Backed by a 4-year unit warranty plus a separate 3-year battery warranty, well beyond Gardena's standard consumer coverage.
- Part of a full iQ-series range from 0.5 acres (410 iQ) up to 2 acres (440 iQ), plus the AWD 435 iQ for slopes up to 70% (35°).
- Sold through a global dealer network with professional install available, on top of retail/Amazon availability.
Husqvarna’s premium comes with real tech: skip the trenching, cover more ground, and get a warranty that outlasts Gardena’s by years. See our full best Husqvarna Automower guide for the complete iQ lineup.
Head-to-head: who wins each category
- Upfront price: Gardena. The Sileno Flex costs less than a sixth of Husqvarna’s flagship 440 iQ.
- Navigation: Husqvarna. Wire-free EPOS across the entire iQ series; every US Gardena still needs a buried wire.
- Coverage ceiling: Husqvarna. Up to 2 acres residential (more with AWD/commercial tiers) versus Gardena’s 0.2-acre max.
- Warranty: Husqvarna. A 4-year unit plus 3-year battery warranty beats Gardena’s standard consumer coverage by years.
- Slope handling: Husqvarna. The AWD 435 iQ climbs up to 70% (35°); Gardena tops out at 35% across the line.
- Small-yard value: Gardena. Consumer Reports named the Sileno Minimo its top pick for small yards in 2026 — Husqvarna doesn’t compete meaningfully below 0.5 acre.
Gardena vs Husqvarna by the numbers
- 2007: The year Husqvarna Group acquired Gardena, making these two brands corporate siblings rather than true competitors.
- 1995: The year Husqvarna Group’s original Solar Mower created the robotic lawn mower category — the shared engineering root behind both lineups.
- $599.98: The Sileno Flex’s Home Depot price — less than one-sixth of Husqvarna’s 440 iQ ($4,299.99).
- 10x: Roughly how much more coverage Husqvarna’s 440 iQ (2 acres) offers versus Gardena’s Sileno Flex (0.2 acre).
- 3 years: How much longer Husqvarna’s unit warranty (4 years) runs than Gardena’s typical consumer coverage (1-2 years).
The bottom line
If budget is the deciding factor and your lawn is under a quarter-acre, the Gardena Sileno Flex delivers real Husqvarna Group engineering for under $600 — you just accept a wire install and a smaller footprint. If you want wire-free navigation, bigger coverage, and a warranty that actually protects a $3,000+ purchase, the Husqvarna Automower is worth the premium.
