> Quick answer: A used MiR250 in good working condition sells for £18,000 to £28,000 in the UK, saving £15,000 to £25,000 versus the new price of roughly £45,000. Battery health is the most important inspection item: check it via the web interface before committing. Confirm fleet software licence status separately, as it does not transfer automatically with the robot.
The MiR250 is Mobile Industrial Robots' mid-range autonomous mobile robot (AMR), positioned above the MiR100 and MiR200 series in payload capacity and navigation performance. With a 250 kg payload, 2 m/s top speed, and a flexible top module system, it has become one of the most widely deployed AMRs in UK warehouses and manufacturing facilities since its launch in 2019.
When these robots are decommissioned, leased units are returned, or facilities are upgraded to larger MiR models, they appear on the UK secondhand market at significant discounts to new pricing. This guide covers everything a UK buyer needs to know to assess, price, and purchase a used MiR250 with confidence.

| New MiR250 with shelf module | £47,000–£53,000 |
| Used MiR250, excellent condition, low hours | £24,000–£28,000 |
| Used MiR250, good condition, moderate hours | £18,000–£24,000 |
| Used MiR250, fair condition, high hours or battery due | £12,000–£18,000 |
| Used MiR250 top modules (shelf, conveyor, lift) | £1,500–£6,000 each |
Prices at auction can fall below these ranges, particularly for units sold without a MiR Fleet licence or with uncertain battery health. Factor in battery replacement (£2,500 to £4,000) if the state of health is below 75%.
Battery Health: The Most Important Inspection Item
The MiR250's lithium-ion battery pack is the component most likely to require near-term replacement on a used unit. Battery degradation on a heavily used MiR250 can be significant: a unit running two shifts per day for two years may have accumulated 1,000 or more charge cycles, which meaningfully reduces capacity.
How to check battery health:
- Connect to the robot via Ethernet or Wi-Fi and open the MiR web interface (typically at 192.168.12.20 or the assigned IP)
- Navigate to System > Battery
- Note the state of health percentage (80% or above is good; below 70% indicates near-end-of-life)
- Check the charge cycle count
- Review the battery error log for any reported cell faults, overtemperature events, or charge failures
A battery at 65% state of health will deliver significantly reduced runtime: a robot that ran for 9 hours on a new battery will run for roughly 5 to 6 hours in the same load conditions. This is manageable if you have time for mid-shift charging, but it affects operational planning.
MiR uses proprietary battery packs. Replacement must be done through MiR's UK service network or an authorised partner. Budget £2,500 to £4,000 for parts and labour.
Fleet Software Licence Transfer
The MiR Fleet software is a central management platform that coordinates multiple MiR robots, manages maps and missions, and provides scheduling and reporting. Licences are tied to MiR accounts and do not transfer automatically when a robot changes hands.
Before purchasing a used MiR250, clarify:
- Was the robot previously managed under MiR Fleet?
- Is the Fleet licence included in the sale, or does it require a new subscription?
- What map and mission data (if any) is available from the previous installation?
For a single-robot standalone deployment, MiR Fleet is not strictly required: the robot can be operated via its local web interface. For multi-robot deployments or sites requiring centralised scheduling, a Fleet licence will be needed. Current MiR Fleet pricing is subscription-based; your MiR UK distributor can confirm current rates.
If the previous installation's map data is available and your facility layout is similar, it can save significant commissioning time. More commonly, a new site map will need to be created.
Safety Sensor Calibration
The MiR250's safety scanners (Sick nanoScan3) perform zone-based protective stopping. If these zones are misconfigured or the scanners have drifted, the robot will either stop unnecessarily (nuisance stops) or, more seriously, fail to stop appropriately.
Check the following:
- Scanner alignment: the two safety scanners are mounted at the front and rear corners. Verify they are physically undamaged and correctly aligned with the chassis (no visible impacts or misalignment).
- Zone configuration: review the configured safety zones in the MiR web interface. They should match the robot's current top module configuration.
- Nuisance stop frequency: ask the seller about the frequency of unplanned stops in normal operation. Occasional stops in cluttered environments are normal; frequent stops in open areas indicate misconfigured zones or sensor faults.
- Scanner firmware: confirm the Sick nanoScan3 firmware version. MiR updates sometimes require scanner firmware updates; your integrator can verify compatibility.
A full safety sensor recalibration by a MiR-trained technician costs approximately £300 to £600 and is advisable when purchasing a used MiR250 for a new facility.
What to Inspect Before Buying
Beyond battery and safety systems, a thorough pre-purchase inspection of a used MiR250 should cover:
Chassis and Drive System
- Inspect the chassis for any signs of collision damage, particularly to the bumper and scanner mounting points
- Check the drive wheels for wear: the polyurethane tyres should be evenly worn and not cracked or chunked
- Check the castor wheels for smooth rotation and any flat spots
- Verify the drive motor operation by running the robot through a simple mission: listen for any grinding or irregular sounds from the drive motors
Charging and Connectivity
- Test the automatic charging dock connection: the charging contacts on the robot and dock should be clean and making good contact
- Verify Wi-Fi connectivity and that the robot connects to your test network without issues
- Test Ethernet connectivity via the service port
Software and Configuration
- Confirm the MiR software version and check whether it is current
- Review the error and warning log for recurring faults
- Confirm what maps and missions are saved on the robot
Top Modules
If purchasing with a top module (shelf, conveyor, pallet lift, MiR Hook), inspect the module separately:
- Check the mounting interface for wear or damage
- For powered modules (conveyors, lifts), verify all axes and actuators function correctly
- Confirm the module is correctly configured in the MiR interface
Typical UK Use Cases
The MiR250 is deployed across a wide range of UK facilities. Common applications include:
- Warehouse goods movement: transferring picked orders from storage aisles to packing stations, replacing tugger trains on fixed routes
- Manufacturing line feeding: delivering components from a central storage area to assembly lines on a demand-pull basis
- Inter-department transfer: moving goods between departments in large facilities (e.g., from goods-in to quality control to production)
- Hospital and healthcare logistics: transport of linen, waste, and consumables in large NHS and private hospitals (MiR250 is used in several UK hospital trusts)
- Automotive: parts delivery to assembly stations in automotive plants
The MiR250 handles most indoor floor types encountered in UK facilities, including polished concrete, vinyl, epoxy coatings, and standard industrial flooring. It handles floor transitions and expansion joints up to approximately 10 mm step height. It is not suitable for loose surface materials, significant floor gradients above 5 degrees, or outdoor use.
MiR250 vs New: Is Used Worth It?
For most UK buyers, yes. The MiR250's core technology (laser SLAM navigation, safety architecture, top module interface) has not changed significantly since 2019. A 2021 or 2022 unit in good condition with a healthy battery pack will perform identically to a new unit for the vast majority of applications.
The main risks of buying used are battery condition (addressable by inspection and, if needed, replacement) and software version compatibility with your existing MiR Fleet setup (addressable by upgrading the robot software before deployment).
The £15,000 to £25,000 saving versus new is substantial. For a single-robot pilot deployment or for adding capacity alongside existing MiR units, a used MiR250 makes strong financial sense.
