Keenon DinerBot T8 vs DinerBot T5: Two Robots from the Same Family for Restaurants

The T8 is 111 cm tall (body 384×468×1111 mm), weighs 34 kg and travels at up to 1.0 m/s. It carries dishes on three trays with a combined payload of 20 kg, has a 10.1-inch touchscreen and, according to the maker, fits through a corridor from 55 cm wide. Navigation relies on triple stereo vision. The battery lasts “up to 15 hours”; older commercial offers stated 9–12 hours.

The T5 is heavier at 55 kg, which is 21 kg more, and faster at 1.2 m/s. Payload is also 20 kg, but spread over four trays. A 48 V/12 Ah battery (576 Wh) gives 12 hours of work, and up to 15 according to one seller. The robot has a dedicated mapping system for unattended operation, detects moving objects and protects itself against collisions. The height and dimensions of the T5 are not stated in the material available. The difference between “up to 15 hours” and “hours under full load” is therefore worth clarifying with the seller before you sign the order (“How to Read a Robot Datasheet”).

Abroad, the T8 comes out cheaper. In July 2026 US sellers listed the T8 at USD 5,500–11,000 depending on configuration; we took USD 7,000 (about PLN 27,130 (≈ EUR 6,220) at the rate of 3.8762 on 1 October 2026). Dentrealstore prices the T5 at USD 10,000 (about PLN 38,800 (≈ EUR 8,890)), which is 43 percent more than the T8.

In Poland both models are stocked by NetVet (Wrocław) and Edikson (Gdańsk). NetVet lists the T8 at PLN 55,348.77 (≈ EUR 12,680) and the T5 at PLN 61,498.77 (≈ EUR 14,090), so here the T5 is about 11 percent dearer. Take off 23 percent VAT and the two amounts come to exactly PLN 44,999 (≈ EUR 10,310) and PLN 49,999 (≈ EUR 11,460), which suggests the shop shows gross prices. Edikson prices the T5 at PLN 35,900 (≈ EUR 8,230) (without saying whether net or gross) and gives no price for the T8 robot itself. The nominal spread between Polish offers for the T5 therefore exceeds PLN 25,000 (≈ EUR 5,730); always ask for the net price, the scope of delivery and service. We calculate total cost as in “Humanoid Robot TCO: How to Calculate Total Cost”.

The smaller, lighter T8 is sensible in a restaurant with narrow passages and a moderate number of tables (restaurants): the maker states a minimum passage width of 55 cm, and up to 15 hours covers a whole shift. The T5, with four trays and a speed of 1.2 m/s, makes sense in a large dining room, a hotel restaurant or at banquets (hotels), where the number of plates per run counts. Alternatives are the Pudu BellaBot with four trays and 40 kg, the Bear Robotics Servi at a lower price, or the lighter Pudu KettyBot Pro. The whole segment is covered in the category “Service robots”.
