The Keenon BUTLERBOT W3 is a multi-floor hotel service robot engineered for contactless room service, amenity delivery, and guest communication across multi-story hospitality properties. Standing 108.1 cm tall and weighing 48 kg including battery, the W3 is available in two-, three-, or four-compartment configurations — each compartment independently lockable with automatic doors that open only for the specific guest room that placed the order via a unique PIN or phone notification. Total internal storage across all compartments reaches 90 liters, sufficient to carry multiple simultaneous room service orders with serving accessories in a single trip. The 11.6-inch 1080p HD touchscreen serves as the primary guest interaction interface and marketing display during transit. Keenon's 2023 strategic cooperation agreement with Wyndham Hotel Group — one of the world's largest hotel chains with properties in over 95 countries — established the W3 as a validated platform for global hospitality procurement.

The W3's multi-floor navigation capability handles elevator dispatch autonomously, enabling delivery from the kitchen to any guest floor without staff escort. The contactless compartment system addresses the post-COVID preference for privacy in room service delivery: neither the robot nor any staff member enters the guest room, with the guest retrieving their order from the compartment at the door threshold. Four-compartment loading allows the W3 to complete four simultaneous deliveries to four separate rooms in one kitchen-to-floor trip, substantially reducing the number of trips and the number of robot units required to cover a hotel's full room service volume.
