• Weight (150 kg), max speed (1.2 m/s), sound level (at least 66 dB(A)), 36 L recovery tank and 'up to 4.5 h' maximum running time are not on the official web page; they come from the CenoBots product catalog PDF hosted by distributor Nasco (https://www.nasscoinc.com/literature/Cenobots_Autonomous_Brochure.pdf, fetched 2026-10-17). RobotLAB also gives 4.5 h, 331 lbs (150 kg) and about 2.7 h charging. battery_hours is left null because only a maximum is published.
• The Nasco catalog lists a 32 TOPS NVIDIA AI chip for the L4; the current official page says 100 TOPS. The official page is used.
• No IP rating, battery capacity or operating temperature is published on the pages read. Optional CWS-01 workstation (auto water fill, drain, charging, detergent) is available for the L4 and L50 per the catalog.
• Cleaning Parts Direct lists the L4 at $33,967 to $41,060 depending on warranty and workstation, but marked it sold out on 2026-10-17, so it is not recorded as a current price. A RobotLAB manufacturer listing was seen at $32,600 only in search results and not on a fetched page; RobotLAB's own L4 pages show $35,833.
