Guide to cleaning and maintaining your YUKA with Sweeper: what to do (and what to avoid)

Why is maintenance of the YUKA with Sweeper so important?

When it comes to garden care robots, few models stand out as clearly as the YUKA with Sweeper by Mammotion. This remarkable device is the only lawn-mowing robot in the world that combines two functions in a single body: mowing the lawn and automatically sweeping hard surfaces. Thanks to its integrated Sweeper module, YUKA not only keeps the lawn perfectly trimmed, but also removes leaves, pine needles and small debris—leaving the garden neat and clean in every season.

The motorised cleaning system works in synergy with Mammotion’s RTK and 3D vision technology, ensuring precise work paths and higher efficiency than traditional robot mowers. In practice, the YUKA with Sweeper brings together automation, intelligence and sustainability:

• reduces the time you spend on lawn maintenance,
• limits the use of noisy blowers or vacuums,
• and contributes to quieter, more environmentally friendly gardening.

However, precisely because we are dealing with a complex, multi-function machine, the YUKA with Sweeper requires regular maintenance to perform at its best. Like any precision tool, the Mammotion robot can see its performance reduced if exposed over time to dust, moisture or organic residues. In addition, the presence of the Sweeper module—with rollers, brushes and moving mechanical components—makes care even more important: attentive maintenance prevents wear, keeps sensor accuracy high and ensures a long operating life for the robot.

In the following sections you’ll find a complete, up-to-date guide to cleaning and maintaining your YUKA with Sweeper: practical tips, mistakes to avoid and a checklist to keep your robot efficient season after season.

Routine cleaning of the YUKA with Sweeper: what to do after every use

Proper routine cleaning of the YUKA with Sweeper is the first step to preserving its efficiency over time. At the end of each work session, just a few minutes are enough to remove grass clippings, leaves and dust that could interfere with the cutting system or the Sweeper module. These small efforts help prevent malfunctions and ensure the robot always runs smoothly and quietly.

✓ Removing grass, leaves and debris

After use, manually remove grass and leaves that have accumulated underneath and around the Sweeper module. Use a soft brush or a dry cloth to clear slots and edges of the robot, without applying pressure or using metal tools. If needed, you can use a small air blower or a low-power blower to eliminate finer dirt. Avoid any direct contact with water or high-pressure jets, which could compromise internal components.

Thorough cleaning of areas where grass tends to build up—particularly around rollers and brushes—prevents blockages or unusual vibrations. According to Mammotion, keeping air passages and intake openings clear is essential to ensure consistent performance over time.

✓ Checking and cleaning the brushes and wheels

The Sweeper module’s brushes are responsible for picking up leaves and small debris. After every use, check that the bristles are free and not entangled with grass threads or residues. You can gently remove any obstructions using a plastic comb or tweezers. Free and even rotation indicates the system is clean and ready for the next cycle.

The wheels can also accumulate mud, sand or small pebbles, especially on damp ground. Wipe them with a dry cloth or brush to remove such materials: keeping the wheels clean improves traction and reduces tyre wear. A clean contact surface also ensures a smooth return to the charging base, avoiding slipping or deviations.

✓ Cleaning the sensors and the RTK camera

The YUKA with Sweeper’s precision depends on the clear visibility of its sensors and the RTK (Real-Time Kinematic) camera, which allows the robot to orient itself with exceptional accuracy. Even a small amount of dust or condensation can affect vision quality or obstacle recognition.

We recommend gently cleaning optical surfaces with a dry microfiber cloth, or lightly dampened with a neutral cleaner. Absolutely avoid solvents, alcohol or abrasive cloths. Regular sensor maintenance ensures that YUKA continues to operate with the same precision described in Mammotion’s official specifications.

Spending just a few minutes on daily cleaning preserves the robot’s most advanced functions, reduces the need for technical interventions and keeps your garden well maintained with minimal effort.

Periodic maintenance: weekly or monthly

In addition to routine cleaning, the YUKA with Sweeper requires some simple periodic maintenance tasks to keep performance steady over time. These checks—performed once a week or once a month depending on usage—help prevent minor issues and prolong the life of mechanical and electronic components.

✓ Battery and charging contact check

The YUKA with Sweeper’s battery is designed to provide extended runtime, but its efficiency also depends on the cleanliness and proper condition of the charging contacts. Dust, wet grass or soil residues can accumulate on the metal connectors, reducing contact quality and slowing down charging.

Each week, visually check the contacts on both the robot and the charging base. If you notice residues or signs of oxidation, clean them gently with a dry microfiber cloth. Avoid liquid products, solvents or conductive sprays: moisture could compromise current transmission. Small regular upkeep prevents connection errors and helps the battery maintain maximum charging efficiency.

✓ Keeping the charging base clean

An often overlooked aspect concerns the charging base, which can become dirty over time as the robot returns. Each time YUKA comes back from work, the wheels and brushes can drag mud, dust or grass clippings onto the platform, creating a layer that hinders proper alignment of the electrical contacts.

For this reason it’s advisable to periodically clean the base surface with a dry cloth, also removing residues from the side guides and the connector area. If the base is placed on natural ground, make sure it remains level and stable: an uneven or damp surface can cause slight misalignment that prevents automatic charging from starting.

These simple precautions improve the reliability of the charging system and reduce the likelihood of error messages or repeated docking attempts, ensuring YUKA is always ready for the next session.

✓ Cleaning the Sweeper module

The Sweeper module is the heart of YUKA’s collection system. During operation, the front brushes and inner roller capture leaves, needles and small debris that are channelled into the collection bin. To maintain efficiency, it is important to empty the container regularly and clean the bristles.

After each week of use, open the rear compartment and carefully remove accumulated residues. If the brushes appear deformed or worn, you can easily replace them by following the instructions in the official Mammotion manual. A visual check of the roller and side brushes helps identify foreign objects (twigs, grass threads or small stones) that could impair rotation.

Never wash the Sweeper module under running water: moisture can damage the internal motors. Instead, use a dry brush or microfiber cloth to remove debris. Thorough and consistent cleaning ensures efficient collection and reduced energy consumption.

Finally, remember to periodically update YUKA’s firmware via the dedicated Mammotion app: updates improve energy management, optimise work paths and often include fixes that increase the Sweeper module’s precision.

What to avoid: common mistakes in caring for the YUKA with Sweeper

Even though the YUKA with Sweeper is designed to withstand various environmental conditions, there are some practices to avoid in order to preserve performance over time. Small improper habits can compromise sensors, reduce battery efficiency or damage mechanical components. Knowing these common mistakes is the best way to ensure a long operating life for your robot.

✗ Do not use direct water or pressure washers

A frequent mistake is to wash the YUKA with direct water jets or pressure washers. Even if the shell is robust, high-pressure water can penetrate seals and reach internal motors, sensors and electrical contacts.

For cleaning, a dry or lightly damp microfiber cloth is sufficient, along with a small soft brush to remove grass and dust. Avoid harsh detergents, degreasers or alcohol: these may damage plastic surfaces or reduce the clarity of the RTK optics.

✗ Avoid prolonged exposure to sun or rain

Although the YUKA with Sweeper is designed for outdoor use, continuous exposure to sun, rain and moisture can, over time, compromise some parts of the robot. UV rays can fade plastics or dry out seals, while prolonged rain may encourage condensation and corrosion on electrical contacts.

If the robot sits under the sun for long periods, internal temperature can rise, temporarily reducing battery efficiency. Similarly, moisture after heavy rain can make dust and residues adhere to the body or the charging base, creating build-up that may eventually interfere with proper connector docking.

For this reason, it’s good practice to store YUKA in a dry, ventilated place when not in use, especially in bad weather or during extreme seasons. In the next section we’ll see how proper protection and a stable resting area can decisively contribute to the robot’s longevity.

✗ Do not leave the robot idle with a flat battery

Leaving YUKA inactive for extended periods with a completely discharged battery is another mistake to avoid. Lithium-ion batteries can deteriorate internally and lose capacity if left flat for too long.

If you don’t plan to use the robot for several weeks, charge it to about 60–70% and disconnect it from the charging base. Store it in a dry environment away from direct heat sources. This simple precaution preserves battery health and ensures YUKA is immediately operational when it’s time to use it again.

By avoiding these three common mistakes, you can keep your YUKA with Sweeper consistently efficient, minimise the need for technical assistance and extend its useful life over time.

How to protect the YUKA with Sweeper between uses

After each work cycle, the YUKA with Sweeper automatically returns to its charging station. This is exactly where most mud, cut grass and moisture tend to accumulate. Over days, these residues can dirty the charging contacts and make more frequent cleaning necessary. Taking care of this detail is a fundamental part of good maintenance.

The platform: a smart solution against mud and build-ups

Every time the robot performs return manoeuvres, it tends to compact the ground and drag mud and grass residues beneath the charging base. In damp gardens or with tall grass, this area quickly becomes critical: the soil gets dirty, grass grows unevenly and electrical contacts get dirty faster. A platform under the base helps reduce these issues, keeping the surface clean and even.

Using a platform under the charging base therefore simplifies day-to-day maintenance, keeps the return point clean and reduces mud formation even after rainy days. A small trick that results in an efficient robot and a tidier garden.

The role of the garage: protection and design for the YUKA with Sweeper

After covering daily maintenance and charging base cleaning, one fundamental aspect remains: protecting the robot when it is not in use. Although the YUKA with Sweeper is designed to withstand rain and temperature fluctuations, constant exposure to the elements can, over time, affect sensor precision, the aesthetic appearance of the shell and the overall performance of the Sweeper module.

An appropriate cover is not just about keeping off the rain: it preserves cleanliness and reduces the maintenance load. During wetter months, rain and wind can deposit mud and foliage around the robot and on the charging station, increasing the need for frequent cleaning and risking dirty electrical contacts. A well-designed shelter prevents all this and helps keep the robot ready to use at any time.

Why a fully covering shelter matters

When choosing a garage or cover for a robot mower, it is essential that it covers the entire machine, including the Sweeper module and the rear bin. Some partial solutions leave crucial parts of the robot exposed—such as the collection bay or rear sensors—allowing rain and dust to build up exactly where it’s most delicate. Over time, this can mean more manual cleaning, minor malfunctions or material degradation.

A complete cover protects not only the top of the robot, but also the sides and rear, creating a dry, shaded micro-environment that prolongs the life of electronic and mechanical components. It also keeps the work area clean, preventing water from carrying debris towards the platform or charging base.

A complete, well-ventilated shelter is therefore more than simple protection: it’s a piece of preventive maintenance that simplifies care, reduces dirt and keeps cutting and collection efficiency steady. A small investment in order and practicality that makes a long-term difference.
