How the family developed
Leju identifies Kuavo 3, introduced in December 2023, as the model that took its large humanoid program into the market. Kuavo 5 and 5-W followed in October 2025. The family's stated applications include research, data collection, commercial services and industrial manufacturing.12
That range of jobs calls for a more precise brief than “a robot that helps.” A research team may need access for collecting demonstrations; an industrial team may need reliable movement between two workstations. A household project needs evidence of the whole task, including recovery when the surroundings change.24
Kuavo 4Pro
In Leju's May 2026 filing, Kuavo 4Pro is listed at 166 cm, 55 kg and 40 degrees of freedom. It is the upgraded fourth-generation model, still named in the current catalogue. Those figures describe this configuration, not every machine sold under the Kuavo name.12
For an existing development project, the useful question is whether the offered machine matches the hardware and software the project already supports. Confirm the exact sensors, firmware and tools before assuming that work prepared for another Kuavo version will transfer unchanged.31
Kuavo 5 and Kuavo 5-W
The same filing lists the biped Kuavo 5 at 173 cm and 63.5 kg, with 41 degrees of freedom. Kuavo 5-W is the wheeled version for flat factory-floor work, listed at 156 kg and 200 cm when extended. Its 40 degrees of freedom should not obscure the basic difference in mobility.1
Leju lists a 5 kg maximum single-arm load for all three highlighted configurations. Its battery figures differ: at least two hours for 4Pro and 5, with hot swapping, and at least eight hours for 5-W. The stated duty cycles are not equivalent, so ask for an estimate based on the intended activity.1
Software and ownership
Leju provides a Kuavo desktop client for visual motion editing and describes imitation learning on the product page. A buyer should establish which client and firmware support the supplied model, which functions are included and how recorded demonstrations are stored or shared.34
Kuavo belongs to an actively marketed commercial family, but a complete home purchase package is not established here. Request a quotation for the exact configuration, country, software and support. A home-service illustration should not be treated as a promise that a robot arrives ready to manage ordinary household routines.143
