Editorial QA
Checked for sourced parameters, internal links and prohibited claims.
Lower-body assist exoskeletons for logistics are procured to reduce hip and back load during repetitive lifting and walking. The three systems in the ExoSelect database differ sharply in drive type, commercial model, and disclosed data, so a generic top-10 list is useless for a sourcing decision. This FAQ answers the procurement questions that actually determine fit: what is documented, what is missing, and where each system is the wrong choice.
The database classifies three products under logistics with lower-body assist: SafeBoost by Verve Motion, H-WULF by ULS Robotics, and CLOi SuitBot by LG Electronics. SafeBoost is an active soft exosuit using flexible actuators and sensor-triggered hip assistance. H-WULF is a passive waist-assist exoskeleton with aluminium and steel construction and no sensors. CLOi SuitBot is an active wearable lower-body assist robot with joint sensors and an IMU, offering walking and standing assist modes.
These are not interchangeable. SafeBoost targets frequent lifting with hip extension assistance; H-WULF provides passive waist support for repeated lifting; CLOi SuitBot supports mobility and repetitive work with active torque. The drive type alone changes maintenance, battery logistics, and user training requirements.

For a side-by-side view, use the comparison tool and filter by logistics.
Peak assist torque for SafeBoost is unknown. The datasheet gives 80 N assist force and 15 kg lift support, but torque at the hip is the parameter that determines whether the suit matches your lift frequency and load. Without it, you cannot compare SafeBoost to CLOi SuitBot's 25 Nm or to passive systems. Ask Verve Motion for a torque curve at the target hip angle.
Peak assist force for H-WULF is unknown. H-WULF states 30 kg lift support, but passive waist-assist systems deliver force through a spring or elastic element whose output varies with posture. The absence of a force figure means you cannot verify whether the 30 kg rating is a structural limit or an assist target. Request the force-displacement curve and the definition of lift support.
CLOi SuitBot's certifications and standards are unknown. For a powered lower-body device, CE marking and the referenced standard (e.g., ISO 13482) are baseline procurement gates in Europe. LG lists neither, and availability is limited to Asia-Pacific. If you plan to deploy in Europe, you must confirm whether the unit can be CE-marked and under what standard before any pilot.
Warranty and lead time are unknown for two of three systems. SafeBoost states 12 months; H-WULF and CLOi SuitBot do not disclose warranty. Lead time is programme-dependent for SafeBoost and unknown for the other two. In a subscription model, warranty may be embedded, but you still need the service-level agreement terms. For H-WULF, a 3,600 USD indicative price without warranty or lead time is not a total cost of ownership figure.
Clinical evidence is unknown for SafeBoost and not applicable for the others. This is a logistics procurement, not a medical one, but if your safety case relies on reduced injury claims, the absence of published clinical evidence for SafeBoost means you cannot cite it. H-WULF and CLOi SuitBot are not positioned as clinical devices, so that gap is expected.
SafeBoost is available in North America and Europe only, via a subscription programme. That model shifts capital expense to operating expense and includes fleet telemetry, but it also means you do not own the hardware and pricing is not public. For a multi-site logistics operator, the subscription may simplify scaling but complicates exit and data ownership. Confirm data residency and telemetry retention in the contract.
H-WULF is available in Asia-Pacific only, on inquiry, at an indicative 3,600 USD. It is passive, so no battery, charging, or connectivity. That reduces infrastructure but also means no usage data. If your procurement requires fleet analytics, H-WULF cannot provide it. Also confirm whether the CE mark is valid for your jurisdiction and whether the indicative price includes duties and service.
CLOi SuitBot is limited availability in Asia-Pacific, with no public price, no certifications listed, and unknown height range. The 4 h battery life and 1.5 km/h max speed suggest a narrow operating envelope. For a warehouse with 8 h shifts, you would need battery swaps (swappable: yes) and a clear path speed limit. The unknown height range is a fit risk: without it, you cannot confirm whether your workforce falls within the adjustable range.
Only H-WULF has an indicative price (3,600 USD). SafeBoost and CLOi SuitBot have no public price. A total cost comparison therefore cannot be completed from the database. For SafeBoost, the subscription likely bundles service and telemetry, but the monthly fee, minimum term, and replacement policy are undisclosed. For CLOi SuitBot, limited availability and unknown warranty mean you must request a formal quote with support terms.
Battery logistics differ: SafeBoost 8 h with 2 h charge and swappable battery; CLOi SuitBot 4 h with 2 h charge and swappable battery. For a two-shift operation, SafeBoost may cover a full shift without a swap, while CLOi SuitBot would need at least one swap per shift. That affects charger count and spare battery inventory. H-WULF has no battery, so no charging infrastructure, but also no active assistance.
Do not choose SafeBoost if you need a capital purchase with public pricing and a published torque figure. The subscription model and undisclosed price make it unsuitable for buyers who require a fixed asset and a competitive tender based on unit price. Also, if your safety case requires clinical evidence, SafeBoost has none listed.
Do not choose H-WULF if you operate outside Asia-Pacific or need usage data. Regional availability is Asia-Pacific only, and the passive design has no connectivity. If your procurement mandates fleet telemetry or a standard beyond CE (which is listed but without a referenced standard), H-WULF cannot meet it. Also, the unknown warranty is a risk for a 3,600 USD unit.
Do not choose CLOi SuitBot if you need CE marking for Europe or a documented height range. Certifications and standards are unknown, availability is limited to Asia-Pacific, and the height range is not disclosed. For a European deployment, the absence of a CE mark is a hard stop until LG confirms it.
From Verve Motion: peak assist torque curve, subscription pricing schedule, data processing agreement, and the ISO 13482 test report. From ULS Robotics: peak assist force and its measurement method, warranty terms, lead time, and confirmation that the CE mark covers your country. From LG Electronics: certification status (CE or equivalent), user height range, connectivity options, warranty, and a firm price and lead time for limited availability.
Use the inquiry form to request these parameters from the makers, or contact the ExoSelect selection desk for a documented gap analysis. For a broader view of logistics systems, see the logistics category.
The database lists SafeBoost as CE marked and referencing ISO 13482. That is a manufacturer claim; request the certificate and test report to verify scope.
H-WULF lists CE but regions are Asia-Pacific only. CE marking alone does not guarantee availability or service in Europe; confirm with ULS Robotics.
Price is undisclosed. LG lists limited availability and no public price; a formal quote is required.
