Price comparison
Universal Robots sells through distributors and does not publish a global list price. Vention, a U.S. automation supplier, lists the UR20 at $62,990, shipped with its matching control box and teach pendant. Unchained Robotics, a European automation marketplace, lists the CS620 at €30,720 excluding VAT. At an exchange rate of €1 = $1.1229 (19 October 2026), that is about $34,495.
UR20: $62,990
Elite CS620: about $34,495 before VAT
Difference: about $28,495
The UR20 listing is about 1.8 times the CS620 price
The CS620 costs roughly 45% less
The two prices come from different markets. The UR20 figure is a U.S. price, while the CS620 figure is a European price before VAT, import and local support. Palletizing projects also need grippers, pallet sensing, guarding and integration, so itemized quotations remain essential. Even so, the hardware gap is large enough to influence the business case for multi-line palletizing.
Payload
Both robots are rated for 20 kg. Universal Robots also publishes a 25 kg rating for the UR20 under specific boundary conditions defined in its manual, which can help with occasional heavier cases.
In palletizing, the gripper often accounts for 4–8 kg of the payload budget, so the usable case weight is lower than the headline rating. Both manufacturers' payload curves should be checked against the real gripper and case size.
Reach and pallet coverage
The CS620 reaches 1800 mm, 50 mm more than the UR20's 1750 mm. For full-height pallet stacks, both robots typically benefit from a lifting column or pedestal, and Elite offers a lifting column as part of its CS620 palletizing package.
Both robots rotate ±360° on every joint, and their footprints are similar at about 240–245 mm.
Speed and cycle time
The UR20 publishes a maximum tool speed of 5 m/s. Elite publishes a 3.9 m/s maximum for the CS620 in its palletizing announcement and a 2 m/s typical TCP speed in its datasheet. Joint speeds are close, with both robots reaching 210°/s on the wrist joints.
In palletizing, cycle time depends heavily on the gripper, case weight, stack pattern and the safety zone configuration. On paper the UR20 has the higher speed ceiling, which can matter in fenced or area-scanned cells.
Repeatability
Both robots publish ±0.1 mm repeatability, which is more than adequate for palletizing, case handling and heavy machine tending.
Protection and environment
Both arms are rated IP65 as standard. Elite also offers an IP68 CS620 option. The CS620 is rated for −10 to 50 °C, which suits unheated warehouses and cold storage areas, while the UR20 is rated for 0 to 50 °C.
Safety and force sensing
The UR20 publishes 23 configurable safety functions certified to EN ISO 13849-1, PLd Category 3, and complies with EN ISO 10218-1 and UL 1740. A built-in six-axis force/torque sensor rated to ±200 N and ±20 Nm supports force-controlled tasks and payload verification.
The CS620 provides more than 20 configurable safety functions and lists ISO 13849, ISO 10218 and ISO/TS 15066, along with UL and CE. Its control box includes 8 configurable safety inputs and outputs. Buyers who need a documented performance level should request the declarations for the exact configuration.
Neither robot is automatically safe in every application. A palletizing cell still needs a risk assessment covering the gripper, falling cases and operator access.
Controller, programming and connectivity
Universal Robots UR20
The UR20 uses a 12-inch teach pendant running PolyScope. The control box provides 16 digital inputs, 16 digital outputs, 2 analog inputs, 2 analog outputs and 4 quadrature inputs, with Modbus TCP, EtherNet/IP, PROFINET with PROFIsafe and ROS/ROS2.
Elite Robots CS620
The CS620 uses a 12.1-inch teach pendant with a graphical interface, Python scripting, free-drive and offline programming, and can also be operated from a web interface. The control box provides 24 digital inputs, 24 digital outputs, 2 analog inputs, 2 analog outputs and 4 high-speed inputs, with Modbus TCP/RTU, EtherNet/IP and PROFINET. The tool flange supplies up to 5 A at 24 V, which helps with vacuum generators and heavier grippers.

Final verdict
Choose the UR20 when cycle time, built-in force sensing, documented PLd Category 3 safety and access to the UR+ ecosystem justify a higher investment. It is a strong fit for high-throughput palletizing and heavy machine tending in established automation programs.
Choose the Elite CS620 when the priority is cost-effective palletizing and heavy handling. Its 1800 mm reach, IP68 option, wider temperature range, high tool current and turnkey palletizing package make it a strong value option, especially for multi-line deployments.
Both robots handle 20 kg with ±0.1 mm repeatability. The decision mainly comes down to speed, safety documentation and ecosystem against a hardware saving of roughly $28,000 per robot.
