How we compare robot mowers
There is no lawn behind this site. MowerRanker is a catalog: 89 robot mowers from 26 brands, each written up on the same spec sheet so a $600 wire mower and a $5,000 AWD RTK flagship sit in one table with nothing hidden. What follows is where every number comes from, how the lists are ordered, and the things the site refuses to do.
Where the specs come from
Every figure is copied from the maker’s own spec sheet or manual and converted into one set of units: square feet for rated area (acres alongside), percent for slope, inches for cutting width and height, minutes for runtime. That is what lets a Husqvarna and a Mammotion share a row without footnotes. When a number is the maker’s best case (rated lawn size is the obvious one) it is recorded as stated, and the spec guide says so, instead of dressing it up as a measurement.
Why some mowers show no star rating
Stars only show when a named retailer or the maker’s own store publishes an owner-review average that can be linked to — 26 of the 89 mowers clear that bar today. The rest simply have no stars. Amazon’s ratings and review counts are never reused, and no score is ever estimated: an uncited number would be a claim about real customers that nobody could check.
Where the pros, cons and owner notes come from
The pros, cons and owner notes are distilled from people who own the machine: retailer reviews, the makers’ own community forums, lawn-care forums, and long-term published tests. Robot mowers turn over fast and some models are too new for any of that to exist yet; 41 of the 89 entries are marked as written from the spec sheet and press reviews alone, and the page says so. Nothing on the site says “owners report” about a mower whose owners nobody here has read.

How lists are ordered
The listing opens sorted by cited owner rating, with unrated mowers after the rated ones, never mixed in above them. Sort it by price, rated lawn size, slope or review count instead whenever you like. Buying guides are written pieces, and every mower they mention links back to its own catalog entry with the same specs and the same cons, so the argument can be checked against the data.
How the site makes money
When a mower is sold on Amazon, its buy button carries an Amazon Associates tag and MowerRanker earns a small commission on what you buy in the next day. It costs you nothing extra. Mowers sold only through the maker or a dealer link straight to that store, untagged, and earn nothing. Commissions never affect which mowers appear, how they rank, or what the cons say — the sort order is owner rating, price or a spec, never who pays.
What we never do
No paid placement, no pay-to-rank, no award badges for sale, no invented ratings, no invented owners. If any of that ever changes, this page changes first.
Update cadence
New models, discontinued ones, firmware updates that change what a mower can do, and price moves get folded in as they happen rather than on a schedule. Catalog last updated September 2026.
Check the work
Put any two mowers in the catalog side by side and see whether the sheet holds up.
