Restaurants, hotels, stores, and care facilities are all short on staff hours, and many of those hours go to the same trips: plates to tables, towels to rooms, stock to shelves, mops across floors. Service robots take over those trips so people can spend their time with guests, customers, and patients.
Keenon builds robots for each of those jobs, and Knoxlabs carries five of them. This guide compares the DinerBot T9, DinerBot T10, ButlerBot W3, CourierBot S100, and KleenBot C40: what each one does, which industries it fits, what it costs, and what your site needs before you order.
Knoxlabs does more than ship the box. Hardware, software, and deployment support can be quoted together, and our team helps with configuration, integration, shipping, and support.
Commercial service robots handle repetitive indoor jobs in spaces built for people. Keenon's lineup covers three kinds of work: delivery, room service, and floor cleaning.
All five robots map the building, plan their own routes, avoid people and obstacles, and return to charge on their own. They use the corridors and doors already in place, and with integration, the elevators too. A deployment is usually a site survey and configuration, not construction.
Staff stay in charge. Someone loads the tray or compartment, picks a destination on the screen, and the robot does the walking.

Labor is the cost restaurants feel most. Citing National Restaurant Association benchmarks, QSR Pro puts labor at 25–35% of revenue for quick-service locations. QSR Research Hub reports that food-service workers often quit at more than 3% of the workforce each month.
Robots for restaurants don't replace servers. They take over the walking. A robot waiter carries plates out and dirty dishes back, so servers stay at the tables where tips and reviews are earned.
The T9 is built for volume. It carries four trays at up to 10 kg each, 40 kg in total, with adjustable tray heights for plates, bowls, and bus tubs. A battery rated for up to 18 hours covers a full day of service, and it docks and charges on its own.
It needs a 70 cm (27.6 in) path. Busy dining rooms, buffets, banquet halls, and fast casual concepts with long runs from kitchen to table get the most out of it.

Keenon DinerBot T9
Four trays, 40 kg capacity, and up to 18 hours of runtime for high-volume food service.
List price $16,400 · Ships within 10–15 days
View the DinerBot T9The T10 delivers food and sells while it does. A 23.8-inch screen shows menus, specials, or ads between runs, and its movable head turns toward guests. AI tray detection recognizes when a tray has been cleared, so the robot heads back without anyone pressing a button.
It carries 40 kg on an open tray and fits 59 cm (23.2 in) aisles, the narrowest in the lineup. Battery life runs 9 to 12.5 hours. It suits restaurants with tight layouts and venues where the robot doubles as a greeter or marketing screen, including retail.

Keenon DinerBot T10
Food delivery with a 23.8-inch promotions screen, built for tight aisles and customer-facing service.

View the DinerBot T10Choose the T9 if trip volume and long shifts matter most. It has the bigger battery, multiple trays, and the lower price.
Choose the T10 if your aisles are tight or you want the robot to promote specials while it works.
Many busy restaurants run more than one robot. Fleet size depends on route length, trip frequency, and the peak hour, not the average one.
Hotel teams field a steady stream of small requests: towels, toiletries, chargers, a takeout order left at the lobby. Each one pulls someone off the front desk or out of housekeeping. Robots in hotels take those runs.
The ButlerBot W3 carries up to 20 kg in as many as four enclosed compartments with automatic doors, so items stay private and protected on the way up. It rides elevators through IoT integration, so one robot can serve every floor. Keenon rates the battery at up to 12 hours, based on three five-minute deliveries an hour.
It needs a 70 cm (27.6 in) path, which most hotel corridors clear easily. For heavier back-of-house loads such as linens and luggage, hotels pair it with the CourierBot S100 below.

Keenon ButlerBot W3
Enclosed, multi-compartment delivery for guest rooms, with elevator riding for multi-floor buildings.
List price $19,600 · Ships within 10–15 days
View the ButlerBot W3Not every delivery is a plate or a towel. Supplies, packages, inventory, and carts of linens are heavy, and moving them eats hours that staff could spend elsewhere. The CourierBot S100 is Keenon's indoor delivery robot for those loads.
It carries more than 100 kg (220 lb). Obstacle avoidance covers the full 360 degrees, and three emergency stop buttons give staff direct control. Battery life is up to 8 hours, and a 15-second battery swap keeps it running through back-to-back shifts.
The S100 needs a 90 cm (35.4 in) path, the widest in the lineup. It fits hotels, grocery and convenience stores restocking from the backroom, retail floors, offices moving mail and supplies, and light industrial sites.

Keenon CourierBot S100

View the CourierBot S100The KleenBot C40 sweeps, vacuums, scrubs, and dries in a single pass, covering up to 11,840 sq ft (1,100 m²) an hour. It scrubs for up to 5 hours on a charge and handles hard floors and short-pile carpet. Like the delivery robots, it can integrate with elevators and doors.

View the KleenBot C40Hospitals and senior living communities run on the same kind of repetitive trips: meals to rooms, linens, supplies, items moving between departments. Staffing in both is stretched, and every trip a nurse or aide doesn't have to walk is time back with patients and residents.
The ButlerBot W3's enclosed compartments keep deliveries private, and elevator riding lets it work across floors. The CourierBot S100 moves heavier carts of supplies and linens. In senior living dining rooms, a DinerBot T9 can carry meals and clear tables, and the KleenBot C40 keeps hallways and common areas clean on a schedule.

Most sites need no building work. These five checks decide whether a robot will run smoothly from day one:
Knoxlabs reviews your floor plan and routes with you, sizes the fleet, and handles configuration, integration, shipping, and support. Keenon deployments also come with partner support from ProServBots.
The DinerBot T9 suits most busy restaurants, with four trays and up to 18 hours of runtime. The DinerBot T10 is the better choice for tight aisles or when you want an on-screen promotions display. The KleenBot C40 handles floors after close.
The T9 focuses on capacity and runtime, with four trays and a longer battery at a lower price. The T10 adds a 23.8-inch promotions screen and AI tray detection, and fits narrower aisles.
The W3 delivers smaller items in enclosed, private compartments, which suits guest rooms and patient rooms. The S100 carries heavy loads of over 100 kg for supplies, packages, and inventory.
At Knoxlabs, the DinerBot T9 lists at $16,400 and the DinerBot T10 at $19,600. Total cost depends on fleet size, integration, and support, which Knoxlabs quotes together.
Yes, with integration. The ButlerBot W3 rides elevators to reach every floor, and other Keenon models can be set up for multi-floor routes. Elevator integration is checked during the site review.
Usually not. They navigate existing corridors and doors and need a charging spot. Wi-Fi coverage and elevator integration are the two things to check early.
Financing is available for qualified business buyers. Ask about options when you request a quote.
Delivery and cleaning robots suit both settings. The W3 and S100 handle deliveries and supplies, the T9 can serve meals in dining areas, and the C40 cleans common areas.
