About MowerRanker

Two mowers rated for half an acre can behave nothing alike on the same half acre. One follows a wire you buried around every bed and does not care that a maple shades the side yard; the next needs a clear view of satellites and quietly gives up in that same shade. A third reads the lawn with a camera and needs daylight to do it. Rated area cannot separate those three, so the catalog is cut by navigation first: 67 of the 89 mowers here need no perimeter wire, and the ones that do are not the losers of the category — they are the answer under a canopy.

Slope is the second thing the box under-explains. Makers print a percent grade; almost nobody looks at a hill and thinks in percent, so every slope figure carries its degree equivalent beside it. 17 of these mowers drive all four wheels, which is the spec that decides wet grass rather than the headline grade.

Cutting width, cut-height range, rated area, slope limit, runtime, charge time, noise, weight, drive, obstacle sensors, cellular terms and warranty are copied from each manufacturer’s published specification or manual for that model, then put in one set of units — square feet, percent grade, inches, minutes, decibels — so a Husqvarna row and a Mammotion row line up without footnotes. Nothing is measured here. There is no lawn, no test plot and no equipment behind this site, and the pages never pretend otherwise.

The navigation class is the one field we assign rather than copy, because brands sell the same hardware under different names. A mower is filed under boundary wire, RTK GPS, RTK plus vision, vision only or LiDAR based on what its own documentation describes it doing, so that the 5 groups mean the same thing from one brand to the next. The methodology page runs down the full sheet, field by field, and says why each one earns its row.

Everything on a mower’s page that is not a number came from people who put one on their lawn and then said what happened, together with published write-ups that ran past a single afternoon. Robot mowers turn over fast — the catalog runs from 2018 models still on sale to the 2026 arrivals, and the newest of those have not had a season of owners behind them yet. 48 of the 89 entries are written from owner accounts; the other 41 are marked as written from the spec sheet and press reviews alone, and their pages say so on their face. No page here puts words in the mouth of an owner base that does not exist yet.

Stars work the same way from the other end. A mower shows one only when some named, linkable place publishes an average from the people who bought it — 26 of 89 clear that today, and the remaining 63 carry none. Amazon averages are never republished and nothing is ever scored by estimate: a made-up rating says something about strangers’ lawns that nobody could go and check.

Some makers publish a runtime; others publish only “mows until it needs a charge.” Right now the sheet has no runtime for 22 mowers, no charge time for 23, no decibel figure for 9 and no weight for 16. Nothing gets borrowed from the sibling model to fill those in. A number that looks like it was measured, and was not, does more damage to a sheet than an obvious hole in it. Rated lawn size is recorded exactly as the maker states it, best case and all, and the spec guide explains how much to discount it for islands, narrow passages and shade.

Two of us, on evenings and weekends. No office, nobody on payroll, and no relationship with any mower dealer. Not one manufacturer has paid for a place in the catalog, for a better place in it, or to get a complaint taken off its page, and none of them has ever shipped a mower here — there is nowhere to put one. If that ever changes, it gets written on the methodology page before it changes anything else. The privacy policy covers the other half of that question — what visiting here leaves behind.

Every price here wears a tilde because it is a reading taken on one day, not a quotation. Wire mowers in particular are discounted hard at the start of each mowing season, so treat the figure as the band a model sits in and check the seller before you buy.

There is no publishing schedule. New models get added when they ship, discontinued ones stay until the maker stops supporting them, and a firmware update that changes what a mower can do — which happens constantly in this category — gets folded into its page when it lands. These mowers were last read through on September 26, 2026, and that single date is what every listing page, hub and sitemap entry is stamped with, so you can always tell how old the sheet in front of you is.

Found something wrong — a spec that does not match the manual, a mower that should be in here, a price that has moved? Point at the figure. Corrections are the cheapest improvement this site gets.
