The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other dog and cat food, health, gear and grooming we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.

Overview

The GIOTOHUN S11 holds 74 ounces (2.2 liters) of water in a stainless steel housing that weighs about 0.57 kilograms (1.25 pounds), sized at 7.68 by 7.68 by 4.53 inches, similar in size to other compact fountains in this category.

Filtration comes from a two-part system, a carbon filter paired with a sponge filter, plugged into a standard corded electric pump built for indoor use. At $19.95, it undercuts most stainless steel competitors while still using metal rather than plastic for the main bowl.

What sets it apart on this list is its review count, over 12,800 ratings at a 4.3 star average, plus a strong number 5 ranking in the Cat Fountains category, giving it more real-world feedback to judge by than most of the other options here.

Pros

  • Stainless steel construction at a budget price of $19.95
  • Two-stage filtration with a carbon filter and sponge filter
  • Backed by over 12,800 ratings, more feedback than most fountains in this list
  • Compact size (7.68 x 7.68 x 4.53 in) fits tight spaces
  • 2 year warranty

Cons

  • 2.2 liter capacity may run low fast in multi-cat homes
  • Corded design ties it to an outlet, unlike battery or wireless models
  • No app or smart monitoring features

Performance notes

At 0.57 kilograms and 2.2 liters capacity, this is a light, compact fountain built for indoor use. The carbon and sponge filter combination is standard for this price range, and the corded electric pump means it needs to sit near an outlet rather than running cordless.

What buyers say

A 4.3 star average from 12,821 ratings is one of the stronger review profiles in this roundup, and its number 5 ranking in Cat Fountains backs that up, suggesting consistent satisfaction across a large number of buyers.

Frequently asked questions

What kind of filter does the S11 use?

It uses a two-part filter system, a carbon filter for odor and taste plus a sponge filter for debris, both included with the unit.

Is this fountain corded or battery powered?

It's corded electric, so it needs to be plugged in near an outlet rather than running on battery power.

How does it compare to pricier stainless steel fountains?

At $19.95 it's one of the more affordable steel options here, and its large review base, over 12,800 ratings at 4.3 stars, suggests it holds up well despite the lower price.
