Quick Answer: Robomow undercuts Husqvarna on price at every comparable size — the RS630 covers up to 3/4 acre with a 22-inch dual-blade deck for $2,499.00 at Home Depot, while Husqvarna’s wire-free Automower 420 iQ covers less ground (0.5-1 acre) for $3,499.99. The catch is navigation and coverage: every Robomow still needs a buried boundary wire and carries only a 1-year limited warranty per Home Depot’s listing, while Husqvarna’s EPOS satellite navigation skips the wire entirely and comes with a 4-year unit warranty plus a separate 3-year battery warranty. Buy Robomow for a lower price and a wider deck; buy Husqvarna for an easier install and far stronger warranty backing.
Robomow and Husqvarna are the category’s two oldest names — both trace their first robot mowers back to 1995 — but they bet on opposite navigation technologies and never really converged. Below is what each brand actually delivers per dollar in 2026, model by model.

Robomow: lower price, wider deck, still wired
Robomow RS630
- Covers up to 3/4 acre with a 22-inch cutting width — wider than Husqvarna's standard deck, meaning fewer passes on a comparably sized lawn.
- Cutting height adjustable 0.8-3.4 inches across dual brushless motors.
- Rated for slopes up to 20 degrees (roughly 36%) — enough for rolling suburban lots, short of Husqvarna's AWD hill specialist.
- Backed by a standard 1-year limited warranty, per Home Depot's listing — no published multi-year coverage in the US.

The RS630’s case is simple: for a 3/4-acre lawn, its wide deck and $2,499.00 price beat Husqvarna’s equivalent-coverage 440 iQ by well over $1,500. The tradeoff is a one-time wire trenching job and a warranty that’s a fraction of Husqvarna’s. Full lineup and pricing in our Robomow review.
Husqvarna: wire-free navigation, stronger warranty
Husqvarna Automower 420 iQ
- Covers 0.5 to 1 acre using wire-free EPOS satellite navigation — no buried perimeter wire, no antenna trenching, per Husqvarna.
- Backed by a 4-year unit warranty plus a separate 3-year battery warranty — three years longer on the unit alone than Robomow's published coverage.
- Part of a full iQ-series range from 0.5 acres (410 iQ) up to 2 acres (440 iQ), plus the AWD 435X for slopes up to 70% (35°).
- Sold and serviced through a global dealer network built around robotic mowers since 1995, per Husqvarna.
Husqvarna’s edge isn’t cutting width — it’s what you don’t have to do: no wire to bury, no antenna to mount, and warranty coverage that outlasts Robomow’s by years, not months. See our full best Husqvarna Automower guide for the complete iQ lineup.
Head-to-head: who wins each category
- Upfront price at any given coverage tier: Robomow. The RS630 undercuts Husqvarna’s comparable 440 iQ by well over $1,500.
- Cutting width: Robomow. A 22-inch dual-blade deck beats Husqvarna’s standard single-blade width.
- Installation: Husqvarna. Wire-free EPOS skips the trenching entirely; Robomow requires it on every model.
- Warranty: Husqvarna, decisively. A 4-year unit plus 3-year battery warranty versus Robomow’s 1-year limited coverage.
- Slope handling: Husqvarna. The AWD 435X climbs up to 70% (35°); Robomow’s RS630 tops out at 20° (~36%).
- Corporate backing: Tie, different kind. Robomow sits inside Stanley Black & Decker’s tool empire since 2021; Husqvarna is an independent, dedicated robotics manufacturer since 1995.
Robomow vs Husqvarna by the numbers
- 1995: The year both brands built their first robot mowers — Husqvarna’s original Automower and Robomow’s Friendly Machines prototype, making these two the only founding-era brands still selling in the US.
- $1,500+: The price gap between Robomow’s RS630 ($2,499.00) and Husqvarna’s comparably sized 440 iQ ($4,299.99), per Home Depot and Husqvarna pricing.
- 3 years: How much longer Husqvarna’s unit warranty (4 years) runs than Robomow’s (1 year), per Home Depot’s published coverage terms.
- 22 inches: The RS630’s cutting deck width, wider than any standard Husqvarna Automower.
- 70% vs 20°: The AWD Husqvarna 435X’s max slope rating versus the Robomow RS630’s — the widest gap in this comparison.
The bottom line
If price and cutting width matter most, the Robomow RS630 covers a 3/4-acre lawn for over $1,500 less than a comparable Husqvarna — you just have to bury a wire once and accept a shorter warranty. If installation ease and long-term coverage matter more, the Husqvarna Automower skips the trenching and backs you with 4 years of unit coverage.
