Rojeco PTM673 water dispenser without filter

The Rojeco PTM673 is a filterless water dispenser for cats, equipped with a 3.5-liter tank for fresh water and a separate 2-liter tank for used water. The device uses a 2000 mAh battery, is charged via USB-C and can operate without being constantly connected to an outlet, so you can easily place it in a convenient place in your home. The dispenser allows you to program water dispensing times and select portion sizes of 80, 110 or 140 ml, and its noise level during operation is below 30 dB. The PTM673 model measures 332 × 230 × 153 mm, and its design combines ABS plastic with SUS 304 stainless steel components.

No filters or additional consumables

The dispenser design does not require replaceable filter cartridges, so there is no need to regularly purchase new filters during use. Instead of a traditional water circulation system, separate tanks for clean and used water are used, which prevents drain or contaminated water from mixing back into drinking water. This solution also simplifies the daily operation of the device and reduces the number of components that you need to monitor during use.

Programming 24-hour water dispensing

The control panel allows you to set the time of water dispensing and adjust the amount to your pet's needs. You can choose between 80, 110 and 140 ml portions, allowing you to create a schedule that suits your cat's daily routine. The 2000 mAh battery allows for cordless use of the device during operation, and the operating time can last up to approximately 180 days, depending on the settings and frequency of use.

Stainless steel bowl and easy cleaning

The bowl from which the cat drinks water is made of SUS 304 stainless steel, which is very suitable for components that come into regular contact with water. The wide and relatively shallow design allows your cat easy access to the water, and the silicone nozzle directs the water directly into the bowl. The individual components can be disassembled, which makes it easy to remove deposits and regularly clean the dispenser; however, please note that the main part is not waterproof and should not be washed under running water.

Stable construction and quiet operation

The Rojeco PTM673 has a low center of gravity, a large base and non-slip elements that reduce movement and the risk of the device accidentally tipping over. The container is additionally secured with a lock, ensuring that the dispenser remains firmly in place during use. With a noise level of less than 30 dB, the device can also be placed in a bedroom or living room, and the transparent container with a scale allows you to quickly check the remaining amount of clean water.

It is important to know

Before choosing a Rojeco PTM673 filterless water dispenser, it is important to consider how this product will fit your daily needs and routine in caring for a cat or small dog. The most important practical consideration is the balance between the convenience of smart features and the need for maintenance, especially if you want simple use without worrying about accessories. Before buying, pay attention to the role of the filter, capacity and the possibility of easy cleaning.

• Since the product does not contain a filter, water hygiene is entirely dependent on regular cleaning - for some users this will be more practical, but for others it may mean additional care.
• Smart features on a dispenser can make it easier to monitor water levels, but they still require at least basic setup and maintenance from you.
• If you have multiple animals or are away for a longer period of time, it is important to check whether the capacity is large enough, as a model without a filter does not improve the preservation of water freshness.
• Without replaceable filters, you reduce the cost and complexity of maintenance, but you lose the added security of filtration in hard or impure water.

Suitable with limitations – although the dispenser allows for automatic water supply, the absence of a filter means that freshness still needs to be taken care of during extended absences.

Very suitable for users looking for a basic solution without the need for filters or special accessories.

🔴 Caring for larger dogs or multiple animals at the same time

Less suitable, as the capacity and design are mostly optimized for a single cat or small dog.
