Disassembly Xiaomi Roborock S5: detailed instructions with photos and tips

Why Roborock S5 Disassembly May Be Needed and What You Need to Know

Xiaomi Roborock S5 is a reliable cleaning assistant, but even the best equipment requires maintenance. Over time, dust, hair and debris accumulate inside the case, which can not always be removed by standard methods.

Deep cleaning of turbine fan, brushes and sensors, replacement of worn parts (for example, side brushes or main shaft), and also for diagnostics of malfunctions - if the vacuum cleaner is not sucking, arbitrarily stops or does not charge. However, it is important to understand that improper disassembly can lead to loss of warranty (if it is still valid) or damage to fragile elements, such as a laser rangefinder LDS.

This guide will help you disassemble the Roborock S5 without the risk of breaking the device, and we will cover all the steps from tool preparation to reassembling, and give you tips on how to avoid typical errors. If you have never understood the technique before, start by watching video guides (links at the end of the article) and carefully study the mounting schemes.

Preparation: Tools and precautions

Before you start disassembling, make sure you have everything you need. Here's the minimum toolkit:

• ✅ Plastic blade (or mediator) - for careful tweaking of the latches of the body.
• ✅ Cross screwdriver (size) PH0 or PH1) — bottom-cover.
• ✅ Tweezers – help to extract small details, such as spring contacts.
• ✅ Soft fabric or wipes – so as not to scratch glossy surfaces.
• ✅ Container for screws (or magnetic substrate) - so as not to lose fasteners.

Also, prepare the workplace: a flat surface (better cover it with a light cloth so you can see the fallen parts), good lighting and a camera / phone - take pictures of each stage of dismantling.

⚠️ Warning: Don't take down Roborock S5 If you're powered on, disconnect the device from the charging station and hold the 10 seconds power button to discharge the capacitors, which will keep you from shorting.

Step-by-step disassembly: remove the bottom cover and the main modules

So, to start with, the simplest thing is to remove the bottom cover, and this step will open access to the main nodes: the turbine, the brushes, the battery, and the control board.

1. Turn the vacuum cleaner upside down and remove the dumpster and water tank (if installed).
2. Unscrew 4 screws on the bottom cover (they can be hidden under stickers - gently tuck them with a spatula).
3. Insert a plastic blade into the gap between the top and bottom of the case (start at the back where the charging contacts are located). Carefully drive the blade around the perimeter, snapping the clamps.
4. Take the lid off and put it aside, and you'll see the insides of the vacuum cleaner: the battery, the turbine, the control board and the motor of the wheel.

At this point, you can do the initial cleaning, remove the dust from the turbine, check the rotation of the brushes, and inspect the contacts of the battery for oxidation, and if your goal is just cleaning, then you don't have to take it apart.

Disassembly of turbine and suction system: eliminate blockages

If the vacuum cleaner is not good at sucking or making unusual sounds, the problem is most often the turbine or ducts.

1. Disconnect the duct hose from the turbine (it is attached with a plastic clip - squeeze it from the sides and pull it up).
2. Unscrew the 2 screws holding the turbine and carefully remove it. Be careful: inside there may be hair or threads wrapped around the shaft.
3. Take off the turbine impeller (which is mounted on the latches or screw) and clean it of debris. Check the bearings, if they are a luft, the turbine will have to be replaced.

Pay special attention to the air channel, which is where the blockages often form, blow it with compressed air or clean it with a thin wire, and if you notice cracks in the hose, it's better to replace it, too.

⚠️ Warning: Do not use metal objects to clean the turbine! They can damage the blades or the body. To remove plaque, use cotton swabs soaked in alcohol.

Dismantling of battery and control board

If the vacuum cleaner doesn't turn on or discharges quickly, the problem may be in the battery or the control board.

1. Disconnect the battery connector from the board (it is usually black and located next to the battery).
2. Unscrew the 4 screws that hold the battery, and carefully remove it. Pay attention to the polarity when you reverse install it!
3. To access the control board, unscrew another 3 screws (they can be hidden under stickers or thermopaste).
4. Carefully raise the charge by disconnecting all the plumes. Don't pull the wires - they're fragile!

Check the board for darkened elements (this is a sign of overheating), bloated capacitors or oxidized contacts. If you are not an electronics expert, you should take a picture of the board and show the photo to a specialist.

💡

Before disconnecting the plumes, take a picture of their location! This will help to connect them back correctly and avoid errors in the assembly.

Disassembly of laser rangefinder (LDS) and sensors

Laser rangefinder LDS — One of the most vulnerable elements of Roborock S5. He's responsible for building a map of the room, and damage to it can make the vacuum cleaner incapable of navigation. LDS It is only in the extreme case, for example, if:

• 🔴 The vacuum cleaner sees no obstacles or faces them.
• 🔴 The Mi Home app displays an error LDS Error.
• 🔴 The laser module does not rotate or makes creaks.

To get to LDS:

1. Remove the upper cover of the vacuum cleaner (it is attached to the latches - gently put it with a spatula on the back side).
2. Unscrew the screws holding the laser module (usually 3-4).
3. Disconnect the power plume and remove the LDS. Don't touch the mirror or lenses - they're sensitive to contamination!

Clean the module with a soft brush or compressed air, and if you're having a problem with the rotational mechanism, you can drop a silicone lubricant on the axis, but remember, LDS is a non-repairable assembly, and if it breaks down, you'll have to replace it completely.

Cleaning the vacuum cleaner: how to avoid mistakes

Building the Roborock S5 is as much a process as disassembling, and here are the key points to consider:

1. Check all connectors: the plumes should be connected before clicking, without distortion.
2. Make sure the battery is polarized correctly, plus to plus, minus to minus. Mixed contacts can knock the board out!
3. Twisting all screws evenly, without putting excessive effort (especially plastic fasteners).
4. Check the rotation of the wheels and brushes manually - they should move freely, without jamming.

Don't turn on the vacuum cleaner after assembly.

1. Make sure all the covers fit tightly, there are no backlashes.
2. Put the vacuum cleaner on the charging station and wait until it is fully charged (this will take 4-5 hours).
3. Run a test cleaning in a small room, observing the behavior of the device.

⚠️ Warning: If the vacuum cleaner doesn't turn on or behaves inadequately after assembly (e.g., spins in place), immediately turn it off and double-check all connections. A common error is an unconnected collision sensor that causes the robot to "not see" the wall.

💡

The key to assembly is to take your time! Most of the problems after dismantling are due to haste: unconnected plumes, skewed lids or forgotten screws inside.

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when disassembling the Roborock S5, and here are the most common ones and ways to prevent them:

• 🔧 Broken case latches - don't use metal tools to lick the lid! Only plastic shoulder blade.
• 🔋 Short circuit – always turn off the battery before working with the board.
• 🌀 Lost screws – fold them in separate containers or photograph the location.
• 📡 Damaged. LDS — Do not touch the laser module with your fingers, do not drop it.

If you have a problem that is not on this list, check:

• ✅ Roborock Ownership Communities on Forums (e.g., Roborock Owners’ Communities, 4PDA ordredit).
• ✅ Official documentation (the scheme is available on the website Xiaomi).
• ✅ YouTube video showdowns (look for high-rated videos).

Remember, if you're not confident, you should go to a service center, and self-repairing can be more expensive if you accidentally damage the fee or the LDS.
