Mammotion Yuka review ft. long wet grass + sweeper

Most robot mowers only cut grass. The Mammotion Yuka was built to clean up as well: with its sweeper kit attached, a rear brush sweeps leaves, small twigs and clippings into a bin, and the mower drives to a chosen spot to empty itself before carrying on. That makes it a different buy from other RTK mowers. This guide covers the Yuka 2000 and Yuka 1500 specs, how the sweeper kit works, what it costs in slope and battery, what to check on stock and bundles, and which mowers to consider instead.

Quick Verdict

• The Yuka is the pick for flat to gently sloped lawns with trees that drop leaves, where a self-emptying sweeper saves raking. Stock on the Yuka 2000 sweeper bundle has been limited, so the Mammotion YUKA 1500 is worth checking as well. Check whether the sweeper kit is included before buying.
• Pick the Mammotion LUBA 3 AWD 3000 for hills and larger lawns. It has no sweeper, but its all-wheel drive is rated for 80% slopes on up to 0.75 acre.
• Pick the Dreame A3 AWD 1000 for a quarter-acre yard with heavy tree cover, where LiDAR navigation avoids RTK signal problems entirely.

Yuka Specs by Size

Mammotion's Yuka spec sheet lists the two sizes as the same machine with different area ratings:

Both connect over 4G, Wi-Fi and Bluetooth and work with Alexa and Google Assistant. Amazon listings rate the mower for slopes up to 45% (24°) without the sweeper. The size to buy comes down to lawn area and how many separate zones the yard has.

Picking the right size

Measure the grass, not the lot. At 350 square meters per hour, the 1500 needs a little over four hours of mowing time to cover its full rated area and the 2000 close to six, spread over several sessions with recharges in between. A lawn near the top of either rating leaves little room for sweeping runs on the same schedule, so stepping up a size buys slack in leaf season. The 2000's extra zones also matter on yards split into front, back and side strips.

How the Sweeper Kit Works

The sweeper kit clips onto the back of the mower. A powered rear brush flicks debris up into a collection bin, a design closer to a robot vacuum's side brush than to a lawn mower bagger. Mammotion says the Yuka can sweep before, during or after mowing, and lists these sweeper details:

• What it picks up: leaves, grass clippings and small twigs up to about 1.4 inches (3.5 cm) across, including wet leaves after rain.
• Bin size: about 22 liters (0.78 cubic feet).
• Self-emptying: when the bin fills, the mower drives to a dumping spot set in the app, tips the bin out, and returns to where it left off. Mammotion's U.S. page lists up to 100 dumping spots.
• Battery: the sweeper configuration uses the larger 9 Ah battery.

The Trade-Offs of Sweeping

Slope drops sharply with the kit on

The sweeper shifts weight to the back of the mower. Mammotion's spec sheet lists the maximum slope with the sweeper fitted at 18% grade (about 10°), far below the no-sweeper rating. In practice, the Yuka with a sweeper belongs on flat or gently sloped lawns. Hillside yards need a different machine or a plan to remove the kit for the steep sections.

Wet, heavy clippings are harder than leaves

Dry leaves are the sweeper's best case. Large volumes of long, wet grass clippings are the hardest: they clump, fill the bin fast, and can wrap around a brush. The workable approach is the one robot mowers are designed for anyway: mow often so each pass removes only a little, and run the sweeper when the lawn is dry. After a long gap in mowing, cut the grass down first and sweep on a later dry day.

Plan the dumping spot

The dump zone needs to be off the lawn but reachable, such as a mulch bed edge, a compost corner or a spot by the fence. Dumped piles still need to be cleared now and then, and a dump spot on bare soil can turn muddy in a wet week.

Setup: RTK Station, Mapping and Zones

The Yuka uses an RTK reference station plus cameras. The station goes in an open spot with a clear view of the sky, and Mammotion says the enhanced RTK station can connect to home Wi-Fi or 4G. The cameras keep the mower on track under trees and near buildings where satellite signal weakens, and they detect more than 100 obstacle types, backed by a U-shaped bumper. Lawns are mapped and edited in the Mammotion app, with no-go zones for beds, play areas and pools, and channels connecting zones through narrow passages. The Goat O1000 RTK guide covers antenna placement in more detail; the same principles apply here.

Two practical notes. The Yuka has two drive wheels and a front caster, so deep holes and soft spots can trap the caster; filling holes before the season helps. And Mammotion's own U.S. store now steers buyers toward newer models, so check which version and bundle a listing actually ships, and whether the sweeper kit is in the box.

Routine care

• Pull hair, string and grass wraps off the sweeper brush after heavy runs.
• Wipe the camera lenses so obstacle detection and edge tracking stay sharp.
• Check the cutting discs and swap dull blades, which tear grass instead of cutting it.
• Empty and rinse the bin at the end of leaf season before storing the kit.

Alternatives Worth Comparing

Mammotion LUBA 3 AWD 3000

For sloped or larger yards, the LUBA 3 AWD trades the sweeper for traction. It combines 360-degree LiDAR, network RTK correction and dual-camera AI vision, drives on four independent motors rated for 80% (38.6°) slopes, steps over curbs and roots up to about 50 mm, and covers up to 0.75 acre across 30 zones. Mammotion lists up to 175 minutes of runtime per charge.

Dreame A3 AWD 1000

The Dreame A3 AWD navigates with 360-degree LiDAR and binocular AI vision, so it needs no wire or RTK station and holds position under heavy tree cover. It is rated for 80% slopes and obstacles up to about 2.2 inches, detects more than 300 objects, and is sized for about a quarter acre. An optional trimmer module tightens the edge gap.

For a flat lawn without leaf problems, a camera-only mower is simpler; see the eufy E18 and E15 guide. For multi-acre properties that also need leaf and snow clearing, the Yarbo guide covers a modular yard robot.

Who the Yuka Suits

Good fit: lawns up to half an acre (2000) or 0.37 acre (1500), mostly flat, with deciduous trees, and an owner who would rather not rake every fall. Homes where clippings get tracked indoors also benefit from a lawn that gets swept.

Look elsewhere: slopes steeper than about 10° when the sweeper is needed, thick warm-season turf that grows fast and wet, or properties that would rather mulch clippings back into the lawn. Mulching returns nutrients to the soil, so leaving clippings is a perfectly good choice for many lawns; the sweeper earns its keep mainly in leaf season.

Bottom Line

The Mammotion Yuka is still one of the few robot mowers that can also pick up after itself. Its RTK and vision navigation, two cutting discs and self-emptying sweeper make it a strong match for flat, leafy lawns. The catches are the low slope limit with the sweeper on and spotty stock on the sweeper bundles, so confirm the exact kit before ordering. For hills, an all-wheel-drive LUBA 3 or Dreame A3 is the safer choice.
