The Best Enclosed Delivery Robots for Multi-Floor Offices 2026

Introduction

In a multi-floor office, internal deliveries quietly use up a lot of staff time. Parcels, documents, IT equipment and lunch orders all have to move from the ground floor or mailroom to individual teams, often several floors up. A delivery robot helps only if it can keep items secure, ride the lifts on its own and hand each delivery to the right person.

This ranking compares the PUDU FlashBot, Robotise JEEVES and KEENON BUTLERBOT W3 on that job. All three carry items in closed compartments rather than on open trays, and all three are aimed at multi-floor buildings. The top two finish level on points, and the third is only 1.5 points behind.

Each robot is scored out of 10 on five weighted criteria: enclosed handoff, elevator workflow, corridor access, shift continuity and building integration. Overall scores out of 100 and the ranking order follow ROBOT24’s desk review. The ranking reflects documented capability and editorial assessment, not matched-condition testing in a live building. The methodology appears below.

AT A GLANCE

Rank	Robot	Overall score	Standout specification	Best suited to
1	PUDU FlashBot	82.5/100	IoT elevator and automatic-door integration; password, phone or NFC pickup	Buildings where lifts and doors can be connected to the robot
2	Robotise JEEVES	82.5/100	Modular drawers; cloud lift control used with major lift brands	Offices that need a defined parcel and messenger service
3	KEENON BUTLERBOT W3	81.0/100	Up to four independently accessible compartments with automatic doors	Multiple drop-offs per trip across several floors

The Robots Behind the Rankings

1. PUDU FlashBot: The building-integration specialist

Overall score: 82.5/100

The PUDU FlashBot shares the top score and leads this ranking on building integration, where it earns 9/10, the highest in the group. Its documented elevator integration is the main reason. Sellers describe IoT integration with lifts and automatic doors, and PUDU also offers its own hardware elevator-control solution for buildings where cloud control is not an option.

It matches the other two on enclosed handoff at 9/10. Items travel in enclosed, lockable compartments, adjustable from two to four, and recipients collect them using a password, phone number or NFC verification. It scores 8/10 for elevator workflow and corridor access.

Its weaker area is shift continuity, at 7/10. Published run-time figures vary between sellers, from about 8 to 12 hours, with a charge of around 4 hours and automatic return to the dock. Offices with long or overlapping shifts should confirm real-world endurance.

The FlashBot suits buildings where the lifts, doors and turnstiles can be connected to the robot, and where that connection is the deciding factor.

2. Robotise JEEVES: The office messenger

Overall score: 82.5/100

The Robotise JEEVES is level on points with the FlashBot and has the more even profile: 9/10 for enclosed handoff and 8/10 on every other criterion. Its strongest point for offices is an explicit parcel and messenger workflow, rather than a hotel room-service model adapted for office use.

JEEVES carries items in modular drawers mounted on a motorised base, and the container setup can be tailored to the building. In an office, that means it can run supplies such as printer paper and stationery, or carry parcels and documents between the mailroom and individual teams.

Its lift integration runs through the Robotise Operations Center, a cloud service that calls the elevator and allows 24/7 remote fleet monitoring. JEEVES has been deployed with lift systems from brands including KONE and Schindler, and it uses an on-board motion sensor to confirm which floor it is on. Compared with the FlashBot, it scores one point lower for building integration but one point higher for shift continuity.

JEEVES suits offices that want a defined internal mail and messenger service across several floors.

3. KEENON BUTLERBOT W3: Four drop-offs per trip

Overall score: 81.0/100

The KEENON BUTLERBOT W3 finishes just 1.5 points behind the leaders. KEENON markets it as an IoT elevator rider, and it shares the top enclosed-handoff score of 9/10.

Its compartment design is its strongest practical feature. It can be set up with up to four independently accessible compartments with automatic doors, so one dispatch can serve up to four locations. Sellers list a 20 kg total load, up to 12 hours of battery life and a 70 cm minimum passage width. It scores 8/10 for elevator workflow, corridor access and shift continuity.

Its lowest score is 7/10 for building integration. Lift riding is documented, but the reviewed material says less about door, turnstile or access-control integration than it does for the FlashBot. It also needs about 6.5 hours to charge, which should be planned around the office day.

The BUTLERBOT W3 suits offices where one trip regularly needs to serve several desks or floors.

The tie-breaker is the building itself

The PUDU FlashBot and Robotise JEEVES finish level on 82.5 points, and the KEENON BUTLERBOT W3 is only 1.5 points behind. All three score 9/10 for enclosed handoff, so the decision comes down to how each robot fits the building.

The FlashBot has the strongest documented building integration, including lifts and automatic doors. JEEVES has the clearest office parcel and messenger workflow and slightly better shift continuity. The W3 stands out for serving up to four locations in one trip.

The building’s lift and access-control compatibility should break the tie. Before choosing, offices should check which lift brands and control systems are installed, whether cloud or hardware lift integration is supported, how the robot will pass security doors or turnstiles, and who on the facilities side will own the integration. A robot that cannot ride a particular lift is effectively a single-floor robot in that building.

RANKING EXPLAINED

Parameter	What we assess	Weight
Enclosed handoff	Closed, lockable compartments and secure recipient pickup, such as PIN, phone or NFC verification.	25%
Elevator workflow	How reliably the robot calls, boards and leaves lifts and confirms the right floor.	25%
Corridor access	Minimum passage width and ability to move through office corridors, doors and shared areas.	20%
Shift continuity	Run time, charging time and automatic return to the dock across the working day.	15%
Building integration	Documented integration with lifts, automatic doors, turnstiles and access control.	15%

Each criterion is scored out of 10, and the weighted scores combine into an overall score out of 100. Enclosed handoff and the elevator workflow carry the most weight because secure, multi-floor delivery is the job these robots are bought for.

SCORING DETAIL

These scores are editorial assessments based on documented information and the multi-floor office delivery use case. They are not the result of matched-condition independent testing. Real-world performance will vary with lift brand and control system, access-control setup, corridor layout, configuration and the integration work carried out on site. Lift compatibility, optional features and support terms should be confirmed with the manufacturer, integrator or building owner before purchase.
