KEENON C55 vs C40 vs C30 Cleaning Robot Comparison

KEENON Robotics is doubling down on intelligent facility automation with a complete range of cleaning robots designed for different floor types and operational scales. The new flagship C55 joins the existing C40 and C30 models, forming a versatile trio aimed at commercial spaces that require reliable, autonomous cleaning. As KEENON Robotics continues to dominate global shipments in the service robot sector, this lineup reflects the company’s strategy to match cleaning performance with the diverse realities of modern indoor environments.

C55: High-Capacity Cleaning for Large Indoor Spaces

The C55 stands at the top of the series with its large-scale coverage and high-power suction. Engineered for environments over 3,000 square meters, it combines sweeping, scrubbing, and suction into a single workflow supported by a triple-roller dry-wet separation system. The standout features include a strong 21,000Pa suction system and a sizable 110L clean-water tank, allowing it to operate all day with minimal human input. At 2,376 square meters per hour, the C55 delivers the fastest cleaning rate in the lineup, making it suitable for airports, malls, convention centers, and wide industrial halls.

C40: Balanced Sweeping and Scrubbing for Commercial Facilities

The C40 sets itself apart with synchronized sweeping and scrubbing, offering a versatile approach for medium-sized venues such as supermarkets, office buildings, and retail corridors. While not as powerful as the C55, the C40 is optimized for mixed flooring conditions and prioritizes efficiency and maneuverability. Its compact frame enables easier navigation through tight corners, and its energy-efficient design suits facilities that want steady cleaning performance without requiring the extensive capacity of the C55. As a balanced option, the C40 is ideal for businesses seeking a dependable daily cleaner that still handles substantial commercial traffic.

C30: Specialized Carpet Care for Soft Flooring

Unlike the C55 and C40, which focus on hard-floor maintenance, the C30 distinguishes itself with carpet-specific cleaning powered by a deep extraction mechanism. The robot targets dirt, dust, and embedded debris using its dedicated roller system designed to lift particles from the carpet surface. This specialization makes the C30 the right fit for hotels, conference rooms, carpeted offices, and entertainment venues where soft flooring dominates. Its lightweight build enhances mobility, allowing it to move across carpeted areas with minimal resistance. The C30 rounds out the trio by covering a flooring category that general-purpose robots often struggle to handle effectively.

Operational Intelligence Across the Lineup

All three models benefit from KEENON’s unified intelligence platform, integrating 360-degree perception, LiDAR navigation, and remote management tools. The C55 introduces a more advanced dual-battery hot-swap system, while the C40 and C30 use single-battery designs optimized for daily routines. The shared ability to generate reports, dock autonomously, and avoid obstacles ensures consistent performance across different scenarios.
