For starters, HolaBot is quite spacious, with four large trays that have a capacity of 15kgs or 34 pounds each. That means when filled to the brim, the HolaBot is capable of holding 132 pounds of dirty cups, dishes, bowls, utensils, whatever else you want it to transport. For the average person, just carrying that much weight would require at least 3 to 4 trips back and forth from the table. Even if a utility cart was being utilized, that's a lot of weight to push around in a cart while still having to be careful to prevent any spillage while transporting the bussing tubs. Mindful of that, HolaBot is fully enclosed on the front and sides, so only the rear opening is exposed for quick loading and unloading of the bussing tubs.
