Best Value Used Robots UK 2026: 10 Models Worth Buying Secondhand

> QuickAnswer: The best value used robots in the UK have three things in common: a large gap between new and used price, a mature software ecosystem that keeps them useful for years, and an active support network for parts and service. The UR5e, MiR250, and Unitree Go2 Pro lead on all three counts.

Best Value Used Robots UK 2026: 10 Models Worth Buying Secondhand

Not all depreciation is equal. A robot that costs 50% less used than new is excellent value if it has 8 years of service life remaining and robust manufacturer support. The same discount on a model with a discontinued software platform and no parts availability is a false economy.

This guide applies a consistent value framework to identify the 10 used robots that represent the best purchase decisions in the UK in 2026. The criteria are: capability relative to used price, remaining service life, SDK and software support quality, parts and integrator availability, and Robot Resale Index pricing trends.

How We Define Value

Value = Capability Gap x Support Quality x Remaining Service Life / Used Price

The robots on this list score highly on the numerator and have used prices that reflect the denominator accurately. They are not necessarily the cheapest robots available, but they are the ones where the mathematics of the purchase is most favourable.

The 10 Best Value Used Robots in the UK

1. Unitree Go2 Pro — Best Value Quadruped

Used price: £1,800 - £2,300 New price: ~£2,800 Saving: 18 - 35% Resale trend: Rising (+18.4% year on year)

The Go2 Pro is the most capable research quadruped available at its price point, new or used. 4D LIDAR, Intel RealSense depth camera, ROS2 and Python SDK support, and an active developer community make this the benchmark used advanced robot for 2026.

Prices are rising, not falling. The developer ecosystem has matured around units that have been in deployment for 12 to 24 months, which means 2023 to 2024 production units with documented histories command premiums. Waiting for prices to drop is a strategy that has not paid off for the past two years.

Inspect: joint condition (each of the twelve joints manually with power off), battery cycle count (target under 200 cycles), all sensor outputs. Best for: university robotics labs, commercial R&D, developer and SDK projects.

2. Universal Robots UR5e — Best Value Cobot

Used price: £10,000 - £18,000 New price: ~£26,000 - £32,000 Saving: 40 - 55% Resale trend: Stable with increasing supply

The UR5e is the single most defensible used robot purchase for UK small and medium manufacturers. Nothing in the cobot market matches the breadth of its integrator ecosystem: thousands of UK and international integrators have experience programming and deploying UR cobots, which means commissioning costs are competitive and support is available even if Universal Robots' direct service is unavailable.

The e-Series platform introduced improved force sensing, teach pendant, and safety capabilities over the original UR5. Used e-Series units are the version to buy. Verify the software version (Polyscope) is current and that the control box has not been damaged.

Inspect: joint calibration (run Polyscope diagnostic), teach pendant condition, control box fans, cable management. Best for: small manufacturers, assembly applications, machine tending, pick and place.

3. PUDU BellaBot — Best Value Service Robot for Hospitality

Used price: £8,000 - £11,000 New price: £14,000 - £18,000 Saving: 30 - 40% Resale trend: Increasing supply in 2026

The BellaBot leads the UK used service robot market by transaction volume. PUDU has an established UK service network, making parts and repair accessible. The 2021 to 2022 deployment cohort is now producing used units at increasing rates as restaurant operators refresh their fleets.

The cat-face interaction interface is well-received by restaurant customers, which matters for front-of-house applications where customer comfort is important. The four-tray configuration handles most UK restaurant service scenarios.

Inspect: fleet software licence transfer (critical), LiDAR calibration, battery health (BMS report), tray flatness. Best for: restaurants, cafes, hotel dining, care home meal delivery.

4. MiR250 — Best Value AMR

Used price: £18,000 - £28,000 New price: £40,000 - £55,000 Saving: 35 - 50% Resale trend: Stable, increasing supply from logistics refresh

The MiR250 is the most widely deployed AMR in UK manufacturing and logistics environments, which means used units are relatively easy to find, parts are available, and local integration expertise exists. It carries a 250 kg payload, navigates autonomously in mixed-use environments, and integrates with most warehouse management systems through the MiR Fleet platform.

Battery condition is the critical variable. MiR uses Lithium Iron Phosphate (LiFePO4) batteries with a rated cycle life of 2,000+ cycles. A used MiR250 with under 1,500 charge cycles still has significant battery life remaining. Above 2,000 cycles, budget for battery replacement at £3,000 to £5,000.

Inspect: battery cycle count (BMS report), LiDAR sensor calibration, wheel wear, fleet management software licence status. Best for: manufacturing intralogistics, warehouse transport, distribution centre applications.

5. DOBOT CR5 — Best Value Budget Cobot

Used price: £4,000 - £7,000 New price: £9,000 - £12,000 Saving: 35 - 50% Resale trend: Stable

The DOBOT CR series is the most accessible cobot family in the UK at new prices, and the used market reflects that with the lowest entry point for a capable 6-axis cobot. The CR5 handles 5 kg payload at 900 mm reach, covering the majority of light assembly, dispensing, and pick and place applications.

DOBOT's UK presence has grown significantly since 2022. The Lua and Python programming environments are more accessible to non-specialist operators than some alternatives. For cost-sensitive buyers who need a working cobot rather than one with premium integrator ecosystem depth, the CR5 used is the starting point.

Inspect: joint play (check for excessive backlash), teach pendant function, controller unit condition. Best for: SME manufacturers, light assembly, dispensing, educational applications.

See the DOBOT CR cobot buying guide for more detail.

6. KUKA LBR iiwa 7 — Best Value Research Cobot

Used price: £22,000 - £35,000 New price: £65,000 - £80,000 Saving: 50 - 60% Resale trend: Stable

The KUKA LBR iiwa 7 is a 7-DOF research and collaborative robot with integrated torque sensing in every joint, making it the gold standard for contact-rich manipulation research, compliant assembly, and human-robot interaction studies. New price makes it inaccessible for most university research groups. Used, it becomes viable.

7-DOF with joint torque sensing is not a feature available at any comparable price point. KUKA's iiwa has been the workhorse of academic manipulation research for over a decade. The large existing literature base, open-source software (iiwa_ros2, LBRiiwaRos2), and academic familiarity with the platform make used iiwa units genuinely useful assets for research groups.

Inspect: joint torque sensor calibration (requires KUKA diagnostics), software version compatibility with ROS2 drivers, sunrise cabinet condition. Best for: university robotics research, manipulation studies, compliant assembly R&D.

7. NAO v6 — Best Value Educational Humanoid

Used price: £3,000 - £6,000 New price: ~£9,500 Saving: 35 - 55% Resale trend: Stable

The NAO v6 is the de facto standard humanoid for educational robotics at secondary school and university level. It has 25 DOF, a well-documented Python and C++ SDK, and 15 years of accumulated educational resources, open-source projects, and community support.

Used NAO units from universities, research labs, and schools are consistently available. The Choregraphe programming environment is well-supported and accessible to students without specialist robotics experience. For educational institutions with limited budgets, a used NAO v6 delivers more educational value per pound than any alternative.

Inspect: joint wear (wrists and ankles most commonly affected by demonstration use), camera and microphone function, battery condition. Best for: university robotics courses, RoboCup SPL teams, secondary school STEM, research demonstrations.

8. Boston Dynamics Spot — Best Value Industrial Quadruped

Used price: £40,000 - £70,000 New price: £70,000 - £95,000 (configuration-dependent) Saving: 20 - 35% Resale trend: Stable

Spot is the most capable industrial quadruped available used in the UK. The saving versus new is meaningful at this price point, and Spot's operational software, payload ecosystem, and UK support infrastructure from Boston Dynamics are the most mature in the category.

Spot is not for every buyer. It requires operator training, has ongoing software licence costs, and the value case depends on an application that genuinely benefits from its terrain capability and payload ecosystem (inspection, data collection, remote operations). For the right application, used Spot is a strong purchase. For applications that a cheaper AMR or cobot could serve, it is not the right tool.

Inspect: all payloads and associated licences must transfer explicitly, leg joint condition, battery condition, arm attachment (if included) calibration. Best for: industrial inspection, hazardous environment data collection, construction site monitoring, research.

9. Franka Research 3 — Best Value Research Arm

Used price: £12,000 - £20,000 New price: £30,000 - £38,000 Saving: 35 - 50% Resale trend: Stable

The Franka Research 3 (FR3) is the dominant robot arm in academic manipulation research globally. Its combination of 7 DOF, joint torque sensing, sub-millimetre repeatability, and comprehensive ROS2 support (franka_ros2) makes it the most capable accessible research arm available.

Universities and research groups that deployed Franka Panda and FR3 units in 2021 to 2023 are beginning to refresh or redeploy, producing used supply. A used FR3 at 40 to 50% below new, with documented research lab history, is one of the strongest purchases available for any research group working on manipulation, learning from demonstration, or human-robot interaction.

Inspect: joint stiffness calibration, torque sensor baseline against specification, controller unit, FCI software licence status. Best for: university manipulation research, reinforcement learning, learning from demonstration, assembly research.

10. Husqvarna Automower 315X — Best Value Domestic Robot

Used price: £600 - £1,000 New price: £1,500 - £1,900 Saving: 40 - 55% Resale trend: Stable with steady supply

The Automower 315X is the outlier on this list: the only domestic robot that consistently holds value and makes genuine sense to buy used. Husqvarna's product has a track record measured in decades, a UK dealer network for service and parts, and a real secondary market with reliable pricing.

Unlike robot vacuums (which are typically not worth buying used due to battery degradation and rapidly obsoleting technology), the Automower's core function is mechanical: cutting grass reliably and repeatedly. Battery replacement is straightforward and affordable (approximately £120 to £200). Blade replacement is routine maintenance.

A used 315X with a mid-life battery and verified charging dock is one of the most practical used robot purchases available at any price point.

Inspect: blade condition and housing, boundary wire kit (confirm included), battery capacity, charging dock condition, GPS module function. Best for: gardens up to 1,500 sq m, low-maintenance regular mowing, anyone who wants reliable automation without complexity.

How to Use the Robot Resale Index to Find Value

The Robot Resale Index tracks used robot prices across every major category and model in the UK market. For buyers, the most useful data points are:

• Current average used price vs new price — the percentage gap tells you where the value is
• Price trend direction — rising prices mean buy now; flat or falling prices mean you can afford to be patient
• Price volatility — high volatility means the market has not settled and you can potentially find outlier deals

For the categories on this list, the Index currently shows the UR5e at the widest gap between new and used prices of any cobot, the MiR250 with increasing supply from logistics refreshes, and the Go2 Pro rising against trend (the only model on this list where the urgency of buying now is highest).
