Each rise in the grade of the watering can permits it to water a larger rectangle of tiles with one tool use. While the upgrade allows the tool to spread the water more effectively, reducing water usage per tile, one tool use at a higher level of operation does still consume a greater quantity of water overall. The base operation uses one water charge per tool use. The copper operation uses two charges per tool use, the steel operation, three, the gold operation, four, and the iridium operation, five. But the iridium operation waters eighteen tiles, meaning it uses only five eighteenths (a little over a quarter) as much water per tile. Thus, the upgraded tool not only has more charges, but each one can spread water over a greater territory.

With only 40 charges, the base level tool can cover 40 tiles before it needs refilling. With 55 charges, the copper tool, using the '''base''' operation, covers 55 tiles. But using the copper '''operation''', it covers 84 tiles. Using two charges per tool use, 27 tool uses consume 54 charges, leaving only one charge. The game does not treat the tool as empty, however, but allows one more use (the 28th), and since each use covers three tiles, 28 times 3 accounts for the 84 tiles the watering can can cover in one refill.

That is more than double the maximum coverage of a base-grade tool.

In general, if any near-empty upgraded tool contains a smaller number of charges than normally required by an advanced operation, the game permits that one final operation before it is considered empty. The gold grade tool, capacity 85 charges, used four at a time, gives 21 tool uses (84 charges) plus one more (for 22 uses), and each use covers 9 tiles, for 22 times 9 (198) tiles watered with one fill. Maximum coverage for a steel can works out to 120 tiles. An iridium can's maximum is 360 tiles.
