Husqvarna publishes the more usable spec data, and Gardena’s official pages gave us almost none to compare against. Husqvarna’s US Automower page lists a rated lawn size for each of its 10 models, a slope figure for one of them, and a boundary type for each. The Gardena SILENO pages we could read list no lawn area, slope, cutting height or noise level. So a fair Gardena vs Husqvarna robot mower comparison has to start with the same few fields on both brands and say plainly where the data stops.
The short answer
- Lawn size: Husqvarna rates each Automower model, from 0.5 acre (410 iQ) to 2 acres (440 iQ, 580 EPOS). Gardena’s official SILENO pages give no area.
- Slope: Husqvarna says the 435 iQ AWD “navigates slopes up to 70%.” No Gardena slope figure appears on the pages we read.
- Boundary: Husqvarna lists physical wire or virtual wire per model and calls its EPOS line wire-free. Gardena’s SILENO accessories include a 150 m boundary wire.
- Noise: Husqvarna states about 60 dB for an Automower against about 90 dB for a gas mower. No Gardena dB figure was published on the pages we read.
- Our reading: for any Gardena vs Husqvarna robot mower shortlist, confirm lawn size, slope and boundary type in the model’s manual before you compare prices.
What the official gardena vs husqvarna robot mower pages publish
Husqvarna’s US robotic lawn mower listing shows 10 Automower models and names a lawn size for every one of them. Slope and cutting height are much less consistent: only one model carries a slope rating, and none of the listed models gives a cutting height or noise level on that page. The comparison page explains the general case, with a typical Automower at about 60 dB.
Gardena’s official pages were a different story. The Canadian product page for the SILENO legacy model (article 4052-60) gives no area, slope, cutting width, cutting height, noise or battery figures. Its accessories list includes a “Boundary Wire 150m” and couplers, which suggests a boundary wire system, but the page does not say so for this model. The international SILENO page (article 4052-20) lists spare parts and manuals without technical specifications. Retailer listings for Gardena models were not used here, because the retailer pages we tried could not be read during this check.
Husqvarna Automower lineup by lawn size
Husqvarna’s listing rates each model by lawn size, with a tolerance of about 20 percent. The table below uses those ratings and the boundary types the page shows. It is the most complete official data we could read for either brand.
| Husqvarna model | Stated lawn size | Boundary type listed |
|---|---|---|
| Automower 410 iQ | 0.5 acre | Physical wire, virtual wire |
| Automower 420 iQ | 1 acre | Physical wire, virtual wire |
| Automower 440 iQ | 2 acres | Virtual wire, physical wire |
| Automower 435 iQ AWD | 1.3 acres | Virtual wire, physical wire |
| Automower 435X AWD | 0.9 acre | Physical wire |
| Automower 560 EPOS | 1.5 acres | Virtual wire |
| Automower 580 EPOS | 2 acres | Virtual wire |
| Automower 535 AWD EPOS | 1 acre | Physical wire, virtual wire |
| Automower 580L EPOS (golf and sports turf dealers) | 2 acres | Virtual wire |
| CEORA | 6 acres | Virtual wire |
Read the table as a starting point, not a verdict. A rated size tells you the area the model is built for, but it does not tell you how a particular yard’s shape, trees or slopes will affect run time. Gardena’s official pages give no matching size column, so a size-for-size comparison against Gardena is not possible from the sources we read. Our guide on how to choose a robot mower by lawn size shows how to measure your own yard first.
Slope and all-wheel drive
Slope is where the two brands are hardest to compare on official data. Husqvarna’s listing states that the 435 iQ AWD “navigates slopes up to 70%,” and the same page offers a slope filter running from 45 to 68 percent without tying those values to specific models. The listing does not say which other models handle which slopes. Husqvarna’s Automower 435 iQ AWD product page adds detail for that one model: slopes up to 70% inside the installation area and 50% at the boundary. Our guide on how steep a hill a robot mower can handle explains how to read such ratings.
Our reading is that a 70 percent claim should be checked against the actual slope in your yard, measured as rise over run, and against the manual’s own limit for the model you buy. We found no Gardena slope figure on the official pages we read, so no slope comparison between the two brands is possible from these sources.
Boundary wire versus wire-free
Most robot mowers need a boundary wire, which is laid around the lawn to define the cutting area. Husqvarna’s listing tags each model as physical wire, virtual wire, or both. The comparison page goes further: “EPOS robotic mowers are wire-free!” It does not explain how EPOS finds its way, and it does not say how the wire-free models are installed.
The Gardena legacy page includes a 150 m boundary wire in its accessories, which points to a wire-based system for that model. Our reading is that the boundary type decides installation time and how easily you can reshape the cutting area later, so confirm it model by model before you compare brands. For the basics, see whether robot mowers need a boundary wire.
Noise on the lawn
Husqvarna gives the most direct noise comparison. Its comparison page says an Automower “produces around 60 decibels of sound” and that a typical gas lawn mower produces around 90 decibels. The company says this makes the robot “33% quieter than gas,” which it describes as about the level of an average conversation.
These are Husqvarna’s general figures, not per-model measurements, and the page does not state Automower noise by model. The 435 iQ AWD page does list 60 dB(A) as that model’s perceived sound level. Gardena’s official pages gave no dB figure, so the Gardena side of this comparison is missing. If noise matters for neighbors or for running early in the morning, ask both sellers for the measured dB rating of the exact model. For more context, see how loud robot mowers are.
What Gardena’s pages do not tell you
The gap is the main finding of this Gardena vs Husqvarna robot mower comparison. The Gardena pages we could read name the SILENO models and link to manuals, but they do not publish the fields that buyers usually compare: lawn area, slope, cutting width, cutting height, noise and battery. Anyone looking for those numbers will need the operator’s manual for the specific model or a spec sheet from the seller. Our guide to reading a robot mower spec sheet explains what each field means.
That gap does not show that Gardena mowers are weaker or stronger. It only means the figures are not in the sources we could check, so this article does not rank the two brands.
Who each brand suits (our reading)
For a Gardena vs Husqvarna robot mower decision, our reading is that the choice starts with lawn area and slope, because those set the limits of every model. Husqvarna’s listing gives a size and, in one case, a slope for each model, which makes it easier to match a model to a lawn before you buy. A buyer who needs a wider range of published numbers will get more from the Husqvarna pages today.
A buyer who already has a Gardena model in mind should request its full spec sheet, including area, slope, cutting height and noise, and compare those against the same yard measurements used for Husqvarna. Without matching numbers, the brand comparison rests on a single side.
How to compare any two robot mowers
Use the same five steps for a Gardena vs Husqvarna robot mower check or any other pair of models.
- Measure the lawn first. Record the area, the steepest slope, and the number of tight corners or narrow passages.
- Match the rated size with a margin. Leave room above the lawn’s real area, because the listed sizes carry a tolerance.
- Check the slope limit in the manual. Do not rely on a slope claim from a marketing page alone.
- Confirm the boundary type. Physical wire, virtual wire and wire-free systems install very differently.
- Ask for the noise rating. Request a measured dB figure for the exact model, not a brand average.
Frequently asked questions
Which brand has the larger lawn range?
In the Gardena vs Husqvarna robot mower match-up, Husqvarna’s US listing rates its 10 Automower models from 0.5 acre to 2 acres, and its CEORA model at 6 acres. Gardena’s official pages we read published no lawn area, so a range comparison cannot be made from those sources.
Do Husqvarna wire-free mowers need no boundary wire?
Husqvarna says its EPOS robotic mowers are wire-free. The comparison page does not describe the installation, and the listing does not say which models use which system, so check the manual for the model you want.
How loud is a robot mower compared with a gas mower?
Husqvarna states that an Automower produces around 60 decibels and a typical gas mower around 90 decibels. These are general figures, and the page does not give per-model noise levels.
Can a robot mower handle a steep yard?
Husqvarna’s listing says the 435 iQ AWD navigates slopes up to 70 percent. It does not give slope ratings for the other models. Measure your yard’s slope and confirm the limit in the manual before buying.
