Two Robots, Two Pain Points
At TCL Top’s Zhongshan appliance plant, Lepu relieved two repetitive posts with one A300 Pro delivery robot and one S140 floor cleaner under its robot staffing model – a 200-meter cart shuttle and hour-long sweeping runs, with staff redeployed to higher-value work.
Two Robots, Two Pain Points
The Hidden Cost of Repetition
On the surface it looked like a small problem: a cart shuttling parts between two points on the line – about 100 meters each way – and a spacious shipping floor that kept collecting dust and packaging scraps. Underneath sat real costs: one full-time employee doing nothing but pulling a heavy cart back and forth; delivery timing that drifted with fatigue and shook the line’s rhythm; cleaning coverage that missed corners under heavy workloads; injury risk from repeated heavy labor; and chronically high turnover on the dirty, tiring, repetitive posts that are hardest to hire for. For appliance makers watching labor costs climb, these low-value posts are a quiet, persistent drain.
A300 Pro Takes the Shuttle
Every production cycle used to send a worker hauling a loaded cart from point A to point B – about 100 meters each way, 200 meters round trip. An A300 Pro now runs the route on its own: 300 kg rated capacity easily carries the cart and its parts; SLAM 2.0 mapping with front-and-rear dual LiDAR builds a high-precision map for centimeter-level positioning and smart routing; fused lidar, depth-camera and ultrasonic sensing reads static and moving obstacles for safe human-robot cooperation; and when the battery runs low it recharges itself and resumes work, enabling 24-hour unattended operation. Single-trip delivery time has fallen from 3-5 minutes to about 2 – roughly 60% faster.
S140 Owns the Shipping Floor
The finished-goods shipping area is wide open, busy with people and transfer carts, and constantly collects dust and packaging scraps. An S140 now cleans it on a scheduled loop: a self-lifting roller brush hugs edges for zero-gap wall-side cleaning of oil, dust and industrial debris; floor-scrub and dust-push modules swap quickly for varied tasks with no manual intervention; multi-sensor AI perception recognizes handrails, isolation barriers and forklifts and steers safely through dense foot traffic. It refills and drains water itself, resumes after power cuts and re-covers missed patches, archives data to the cloud, and takes remote commands from mini-program, app or web. Manual passes that took over an hour now finish in about 30 autonomous minutes, never interrupting shipping.
Robot Staffing, Zero Asset Risk
Both robots are delivered under Lepu’s robot staffing model: the customer pays rent by period while Lepu covers deployment, commissioning, maintenance and ongoing service – no depreciation or repair risk on the customer’s books. The two dedicated posts previously cost 110,000-120,000 RMB a year in labor; the robots’ annual investment now runs about 72,000 RMB. The former cart handler has moved on to assembly and quality-inspection posts, and cleaning staff focus on finer tasks. The workshop lead’s verdict: ‘The two robots just run by themselves, so people can take on more skilled work.’
Lightweight Deployments, Fast Payback
Two robots under one rental model relieved two repetitive posts, with staff redeployed to higher-value work.
Line delivery about 60% faster: 3-5 minutes down to 2
Stable material flow takt with consistent 5S housekeeping standards
Cleaning passes halved, from over an hour to about 30 minutes
Two posts' 110-120k RMB labor replaced by 72k robot annual cost
Robot staffing rental: no depreciation, no repair risk
