How to read this table: multipliers and Water prices for pumps through Venom are confirmed by independent in-game verification plus the actual Roblox developer-product feed; values above that tier rest on a single guide lineage and are labeled accordingly on each pump's page. Two naming notes from primary sources: the top 759-Robux pump is listed in-game as Planet (guides call it Dianeti), and the OG pump appears as Ignisthul. Efficiency score is our original metric: (multiplier − 1) ÷ Water price, normalized 0–100 — see the methodology. Guides also disagree on the pump-shop currency's name (Water vs Cash) — amounts are corroborated either way.
Related: the aura ladder
Auras are a separate Cash-bought Water boost track, documented in-game by Bloxron (August 28, 2026). Smaller than pumps, but they stack on top.
| Aura | Water multiplier | Cost | Robux |
|---|---|---|---|
| White | ×1.2 | 100K | 19 |
| Green | ×1.4 | 1M | 39 |
| Blue | — | — | 99 |
| Purple | — | — | 149 |
| Gold | — | — | 299 |
| Rainbow | ×10 | — | 799 |

Pumps FAQ
What is the best pump in +1 Drain Water Per Click?
Dianeti is the strongest pump: ×4,000,000 Water per click for 15B Water (or 759 Robux). Community tier lists call it the only S-tier pump, with Rocket, Cake, Amethyst and Ice Penguin anchoring the endgame A-tier.
What pump should I buy first?
After the free Water Pump Plus (×5), buy Lucky Clover (×12) for 300 Water, then Sunflower (×30) for 3,000. The standard strategy is to keep buying the next pump you can comfortably afford rather than saving for a big jump.
Do pumps cost Robux?
No. Every pump except Unicorn Fantasy (×31K, 80 Robux) and Cake (×1M, 399 Robux) can be bought with Water. Robux prices are an optional shortcut for the same pump — nothing is Robux-exclusive in effect.
How many pumps are in the game?
21 pumps are documented by public sources as of August 28, 2026, from the free Water Pump (×1) to Dianeti (×4,000,000). New pumps are usually added in updates — we update the table when that happens.
