How They Compare
With regard to usage, Richtech DUST-E S is recorded for applications of commercial floor cleaning whereas KEENON KLEENBOT C20 is recorded for small-to-medium sized indoor facilities comprising workplaces, cafes, retail outlets, hotels and clinics. Both are intended for commercial indoor cleaning, yet the market-research data records for the KLEENBOT C20 list different intended use environments.
On the recorded performance figures, Richtech DUST-E S is about 25.9kg while KEENON KLEENBOT C20 is 22kg and both have a top speed of about 0.6m/s. DUST-E S has a recorded operational time of 3-4 hours and a charging time of two hours, while KLEENBOT C20's charging time is about four hours, with operational time not separately recorded.
A Clean Assist Richtech DUST-E S is documented with sweeping, vacuuming, scrubbing and mopping in a single pass, while KEENON KLEENBOT C20 can do sweeping, vacuuming and mopping with its 3-in-1 cleaning system. Cleaning speed for DUST-E S is estimated at around 756 m/h compared to up to 400 m/h for KLEENBOT C20 and up to 2,000 m per charge. These are recorded figures and are not representative of a single cleaning test.
Water Capacity As per the ROBOT24.com market-research database records, Richtech DUST-E S is available with 10 L tank and 15 L tank capacity, though their roles are not categorized in the provided records. KEENON KLEENBOT C20 has 7 L clean-water tank capacity and 5 L dirty-water tank capacity.
Navigation and autopilot for autonomy and perception Richtech DUST-E S Autonomous multi-sensor navigation and auto-docking requires LiDAR, depth camera, monocular camera and edge, low-obstacle and carpet sensors. KEENON KLEENBOT C20 LiDAR + VSLAM navigation with auto-route planning LiDAR, 3D vision, VSLAM camera, IMU, cliff sensors and collision sensors.
They have other features to cater for different working needs. DUST-E S with a self-maintenance station for automatic water refilling and wastewater emptying, and KLEENBOT C20 with a lower profile, automatic charging and an app/web dashboard for cleaning management.
Summary
Richtech DUST-E S and KEENON KLEENBOT C20 are considered similar equipment within the same general autonomous commercial cleaning market, but the ROBOT24.com market-research data records show different cleaning function, performance, water capacity, charging time, navigation, perception and operation figures for each. The figures above should be read as a head-to-head comparison of specifications between the current ROBOT24.com market-research data records for these cleaning robots.
