Product Overview
The GIOTOHUN S11 is an indoor electric pet water fountain designed to circulate and filter drinking water for cats and other small pets. It has a 2.2-liter, or approximately 74-ounce, reservoir constructed from 304 stainless steel. A transparent water-level window allows the remaining supply to be checked without removing the fountain’s upper section.
The S11 uses a submersible electric pump to circulate water through a replaceable filtration system. The main filter combines several filtration materials, including activated carbon, ion-exchange resin, and a filtering layer, while a separate high-density sponge helps capture debris before it reaches the pump. The fountain supports two drinking configurations: water can flow through the removable faucet-style spout or bubble upward from the central outlet when the spout is removed.
A blue LED illuminates the water-level area during operation. The fountain operates continuously while connected to electrical power and is intended for indoor use. Routine maintenance includes washing the stainless-steel components, cleaning the pump and impeller, rinsing or replacing the pre-filter sponge, and periodically replacing the main carbon filter.

Common Uses
The S11 provides continuously circulating drinking water in indoor environments. Its capacity and drinking-surface design allow it to serve cats and other appropriately sized household pets.
- Providing circulating drinking water for indoor cats
- Providing water for small household pets that can safely use an open fountain
- Serving households with more than one cat
- Offering a running-water drinking point through the faucet attachment
- Providing a lower bubbling flow when the faucet attachment is removed
- Filtering hair and small debris from recirculating water
- Allowing water level monitoring through the illuminated viewing window
Maintenance & Care
The fountain should be disassembled regularly so the reservoir, upper tray, faucet, and other water-contact surfaces can be washed with soap and water. Stainless-steel parts should be rinsed thoroughly before the unit is reassembled.
The main filter should generally be replaced about every two to four weeks. Replacement may be required more often in multi-pet households or when water quality, debris accumulation, or reduced flow indicates that the filter is becoming saturated.
The pump’s sponge pre-filter should be cleaned approximately every one to two weeks and replaced when it becomes worn or difficult to clean. GIOTOHUN maintenance documentation also recommends cleaning the pump about every two weeks. Pump cleaning includes removing the pump cover, impeller cap, and impeller so accumulated hair and residue can be removed.
Water should remain above the minimum operating level. Running the pump without adequate water can reduce cooling and lubrication around the impeller and may shorten pump life.
Safety Information
- The fountain is intended for indoor use.
- Disconnect electrical power before disassembling or cleaning the pump.
- Do not operate the pump without sufficient water in the reservoir.
- Route the electrical cord so pets cannot easily chew, pull, or become entangled in it.
- Do not use the fountain if its pump, cord, adapter, or electrical connection is damaged.
- Keep the electrical adapter and wall connection away from spilled water.
- Place the fountain on a stable, level surface during operation.
- Check the water level regularly to prevent the pump from running dry.
- Unplug the fountain before removing the pump cover or impeller.
- Rinse cleaned components thoroughly before returning the fountain to pet use.

Compatibility
The S11 uses replaceable GIOTOHUN fountain filters designed for this 2.2-liter stainless-steel platform. Replacement filter sets are available with both main filter cartridges and foam pump filters.
GIOTOHUN identifies S11-compatible replacement filter packages separately from filters intended for larger fountain models. Replacement cartridges should therefore be matched by model rather than selected only by shape or brand.
The pump, faucet, filter holder, and reservoir components should also be checked for explicit S11 compatibility before replacement. Similar-looking parts from other pet fountains may differ in size, electrical connection, or water-flow design.
Frequently Asked Questions
How can I identify this GIOTOHUN fountain?
The model is S11. The model designation is useful when locating replacement filters, instructions, pump components, or support information.
Is the S11 made entirely from stainless steel?
The primary reservoir and drinking surfaces are constructed from stainless steel. Functional components such as the pump, filter materials, viewing window, and electrical parts use other materials as required.
How does the filtration system work?
Water passes through a replaceable filter containing multiple filtration materials. A separate sponge positioned around the pump helps capture hair and larger debris before they enter the pump mechanism.
Why does the fountain have both a filter and a pump sponge?
The components perform different functions. The main cartridge treats the circulating water, while the sponge acts primarily as a mechanical pre-filter that protects the pump from hair and debris.
How often should the main filter be changed?
A replacement interval of roughly two to four weeks is documented. Multi-pet use, debris, local water conditions, and visible changes in water quality can require more frequent replacement.
How often should the pump be cleaned?
GIOTOHUN maintenance guidance recommends cleaning the pump about every two weeks. Hair and mineral residue around the impeller can reduce water flow and increase pump noise.
Can the pump be taken apart for cleaning?
Yes. The pump cover and impeller cap can be removed, followed by the impeller itself. These components can then be cleaned before the pump is reassembled.
What should I do if the water flow becomes weak?
Check the reservoir level first. If sufficient water is present, inspect the main filter and pump sponge for clogging and clean the pump and impeller if necessary.
Why has the fountain become noisier?
Low water, pump contamination, vibration, or an uneven placement surface can increase operating noise. Refilling the reservoir, cleaning the pump, and checking the fountain’s position are standard troubleshooting steps.
Does the fountain operate automatically?
The pump runs continuously whenever the fountain is assembled, filled with water, and connected to electrical power. It does not require the pet to activate a sensor.
Does it have different drinking modes?
Yes. The faucet creates a raised stream of circulating water. Removing the faucet allows water to bubble from the central outlet into the drinking surface.
What is the blue light for?
The integrated LED illuminates the water-level area. This makes the remaining reservoir level easier to see in lower-light conditions.
Can the fountain be used without a filter?
The fountain’s documented operating design includes both the main filter and pump sponge. Using the intended filtration components helps reduce debris and protects the circulation system.
Can the S11 be used outdoors?
The S11 is specified for indoor use. Its electrical pump, adapter, and connections should not be exposed to outdoor weather or standing water.
Can dogs use this fountain?
The fountain can provide water for appropriately sized household pets. Its compact reservoir and drinking area make pet size and daily water requirements important considerations.
Does it need plumbing?
No. The S11 is a self-contained reservoir fountain. It is filled manually and requires an electrical outlet rather than a connection to household plumbing.
What warranty applies to the S11?
Public documentation for the model identifies two-year replacement coverage. Warranty claims remain subject to the applicable manufacturer’s conditions and support procedures.
Buying Considerations
The S11 is a corded fountain, so placement requires access to an electrical outlet. The power cord should also be positioned where it is unlikely to be chewed, pulled, or exposed to standing water.
The 2.2-liter reservoir is compact compared with large multi-pet fountains. Water consumption, evaporation, and the number of pets using the fountain determine how frequently it will need refilling.
Ongoing maintenance includes both cleaning and replacement consumables. The main filter requires periodic replacement, while the pump sponge and impeller need routine cleaning to maintain water flow.
The stainless-steel reservoir simplifies access to the main drinking surfaces, but the fountain still contains smaller pump and filter components that need separate cleaning. Owners comparing fountains should account for this recurring maintenance rather than evaluating the reservoir material alone.
Customer Feedback Summary
This section summarizes recurring themes found in publicly available customer feedback and independent product discussions. These observations are generalized user reports rather than verified technical specifications or first-hand testing by iGiftCardz.
Positive feedback commonly focuses on relatively quiet operation, straightforward assembly, and the stainless-steel drinking surfaces. Users also frequently mention the visible water-level window as useful because the reservoir can be checked without fully disassembling the fountain.
The removable faucet and circulating flow receive favorable comments from owners whose cats are attracted to moving water. Routine washing of the reservoir is also commonly described as manageable when the fountain is regularly disassembled.
Reported limitations mainly involve the maintenance required by the pump and filtration system. Some users describe reduced flow when hair or residue accumulates around the filter or impeller. Isolated reports also describe pump or light failures after extended use, making regular cleaning and access to compatible replacement components relevant for long-term ownership.
