The best robot mowers for small yards, our 2026 picks

What to look for on a small lawn

• Lawn size. The table shows how much lawn each brand says its mower covers. Take about a fifth off that figure for beds, paths and corners. Then compare your lawn with what is left. All three cover a lawn under 5,400 sq ft500 m², about an eighth of an acre.
• Gate width. Measure the narrowest gap the mower must drive through, usually a side gate. Only GARDENA gives a figure: 24 in61 cm for the minimo.
• How it finds its way. The GARDENA minimo follows a wire you lay around the lawn, so shade does not matter. The Navimow i105 uses satellites and needs open sky over the whole lawn. The eufy E15 steers by camera and needs daylight and a clear edge between grass and path. In deep shade most of the day, the satellite mower cannot find its position and the camera mower misses patches.
• Noise. All three run at 56 to 58 decibels. Normal talk is 60 to 70 decibels, says the US National Institute on Deafness. So all three run quieter than two people talking.
• Running cost. Blades are the main cost. You replace them a few times a season. The GARDENA adds the wire, which you lay yourself or pay someone to lay.

Best overall: eufy Robot Lawn Mower E15

The eufy E15 covers the most lawn of the three, up to 8,600 sq ft800 m². The other two stop at 5,400 sq ft500 m². On a lawn under 5,400 sq ft500 m² it has more capacity than it needs. So it finishes sooner each day, and it can still mow the whole lawn in May when the grass grows fast.

It steers by a camera on its front. There is no wire to lay and no satellite receiver to put up on a pole. You set it up by walking it once around the edge of the lawn, phone in hand. It learns the shape from that walk. Compared with the Navimow i105, a tree or two over the lawn does not stop it. Compared with the GARDENA minimo, you skip a weekend of laying cable. It can also remember a front lawn and a back lawn as two separate areas. The GARDENA cannot.

It talks to your phone over Bluetooth and your home Wi-Fi, so you start it and check on it from home. It has no cell signal of its own. It runs at 56 decibels, the quietest of the three, so it can mow under a neighbor’s window without disturbing them. It cuts an 8 in20 cm strip on each pass, the widest of the three, so it needs fewer passes to finish. It senses rain and drives back to its charging station on its own. It climbs a rise of 40 ft40 m for every 100 ft100 m forward, the steepest of the three.

The Navimow i105 protects itself better against theft. The E15 has a PIN code and sends an alert to your phone if someone lifts it. The Navimow adds a GPS tracker and an alarm, so its app can show where the mower went. The GARDENA minimo does better in deep shade. The E15’s camera needs daylight and an edge it can see between the grass and the path. So it mows by day only, and it can miss patches in deep shade. eufy also says not to use it on Zoysia or St. Augustine grass, so check what grows on your lawn. Read our full review of the eufy E15 for the details.

Best for a small, open lawn: Navimow i105

The Navimow i105 works out where it is from satellites. A small receiver on a pole in your yard picks up the same signals and corrects the mower’s position. With open sky over the whole lawn, it knows where it is to within a few inches. That gives it the cleanest, straightest edge of the three. The eufy E15’s edge depends on how clear the border of your lawn looks to its camera. The GARDENA minimo cuts its edge along the line where you laid the wire.

It is the pick for a front lawn by the street. It has a GPS tracker, a PIN code and an alarm. If someone carries it off, the app shows where it went. The eufy has no tracker, and the GARDENA has only a PIN. You can also pay for a cellular plan, and then the app reaches the mower from anywhere.

You mount the receiver on its pole and put the pole where nothing blocks the sky. Then you run a power cable out to it. After that, you steer the mower around the edge of the lawn with your phone, and it remembers the shape. It runs at 58 decibels, the loudest of the three. It cuts a 7 in18 cm strip on each pass. You set the cutting height by hand on the mower. The app cannot change it. Its lowest cut is 2 in5 cm, so it cannot cut a lawn shorter than that.

The eufy E15 covers more lawn, works under more trees and climbs steeper ground. One large tree or a tall wall next to the lawn can block the Navimow’s view of the sky. In that corner it no longer knows its own position. It leaves the grass there uncut. It climbs a rise of 30 ft30 m for every 100 ft100 m forward. Along the edge of the lawn it handles only a rise of 10 ft10 m for every 100 ft100 m forward.

Buy the Navimow i105 if your small lawn has open sky all over it and you want a sharp edge. It is also the one to buy if the mower will sit out front by the road.

Best for a shady or tight yard: SILENO minimo 500

The GARDENA minimo follows a wire you lay around the edge of the lawn. You lay the cable once and pin it down, and the mower stays inside it. After that, trees and shade make no difference to it. The Navimow i105 needs open sky, and the eufy E15 needs daylight and a visible edge. The GARDENA minimo needs neither. So it is the one to buy for a lawn in shade most of the day. It also suits a lawn with tall fences on every side.

It is also the only one of the three with a published figure for narrow gaps. GARDENA says it fits through a passage 24 in61 cm wide. If you reach a side lawn through a gap that narrow, check this one first. The other two makers give no figure, so you would compare your gap with the width of the mower itself.

Laying the wire is the biggest piece of work this mower needs. You walk the edge of the lawn with the cable and pin it down with pegs. Then you plug both ends into the charging station. Plan a weekend for it, or pay someone. Once the wire is down there is nothing to put up on a pole and no lawn shape to teach. It talks to your phone by Bluetooth only, so you start it or change settings while you stand near it. It stores one mowing area, so it suits a lawn that is all one connected piece. It runs at 57 decibels, between the other two.

The other two need no cable, and both do more from the phone app. The GARDENA cuts a 6.3 in16 cm strip on each pass. That is the narrowest of the three, so it takes more passes to finish. It climbs the least of the three, a rise of 25 ft25 m for every 100 ft100 m forward. At the edge of the lawn that drops to a rise of 10 ft10 m for every 100 ft100 m forward. Against theft it has a PIN code and nothing else. So it is the wrong one for a front lawn by the street. It does cut as low as 0.8 in2 cm, the lowest of the three.

How loud it runs

Buy the GARDENA minimo if your lawn sits in shade for most of the day and you will lay the wire. It is also the one to buy if the mower must fit through a 24 in61 cm gap.

Which one for your lawn?

• If your small lawn has a tree or two over it, buy the eufy E15.
• If your lawn sits in shade for most of the day, buy the GARDENA minimo and lay the wire.
• If your lawn has open sky all over it, or sits out front by the street, buy the Navimow i105.
• If the mower must fit through a gap 24 in61 cm wide to reach the grass, buy the GARDENA minimo.
• If your grass is Zoysia or St. Augustine, skip the eufy E15 and choose between the other two.

Questions people ask

Is a robot mower worth it on a small lawn? Yes, if you want the lawn mowed without doing it yourself. A small lawn takes a robot less time to cover, so a cheaper, simpler mower does the job. The grass gets cut a little at a time instead of once a week.

Do I have to lay a wire? Only for the GARDENA minimo. The eufy E15 steers by camera and the Navimow i105 uses satellites, so neither needs a wire. Each of those needs something else instead: daylight and a visible edge for the eufy, open sky for the Navimow.

Which one is the quietest? The eufy E15, at 56 decibels. The GARDENA minimo runs at 57 decibels and the Navimow i105 at 58. All three sit within two decibels of each other, and all three run quieter than two people talking.
