When you are choosing care equipment such as an electric nursing bed, a walking robot or a washing robot, you will often see terms like "IP rating" or "IPX6" on the specification sheet. Ingress protection (IP) ratings describe how well a device's enclosure keeps out dust and water. For equipment that is cleaned, disinfected and used around liquids every day, understanding these ratings is the key to choosing products that stay safe, reliable and easy to maintain.
An IP rating is the internationally recognized way of classifying the degree of protection provided by an enclosure against dust and water. It is defined by the IEC 60529 standard. The rating is made up of two numerals: the first describes protection against solid objects such as dust, from 0 (no protection) to 6 (dust tight), and the second describes protection against water, from 0 (no protection) to 9 (protected against high-pressure and high-temperature water jets).
For water exposure, the second digit is what matters most. These are the common water ratings you will meet on care equipment:
A device rated IPX6 can withstand powerful jets of water, while a device rated IPX7 can survive brief immersion. A full rating such as IP67 means the device is both dust tight and protected against temporary immersion.
Care equipment lives in a wet environment. Nursing beds are wiped down with disinfectant, washing robots work directly with water, and rehabilitation robots are cleaned between patients. Water can find its way into motors, controllers, batteries and hand remotes, where it can cause short circuits, corrosion and premature failure.
For a nursing bed, the electric motor, controller and hand remote are the parts most at risk. If these are sealed to a sensible water rating, the bed can be cleaned safely and will keep working reliably for years. For a washing robot, water protection matters even more, because the device is designed to work around water and cleaning tasks by nature.
Mona Care (Oakon Tech Inc.) is an online sales platform for life care products. Working directly with producers, it strives to provide genuine products that focus on good quality and competitive prices. Its range covers nursing beds, exoskeleton robots, patient transfer devices, walking robots and wheelchairs, laser pain relief devices and washing robots.
Mona Care's electric multifunction nursing bed offers back lifting, leg lifting and lowering, left and right turning, catering and in-bed toilet functions. Because these beds are used in welfare institutions and homes, where they are cleaned and disinfected regularly, water-resistant electrical construction helps keep them safe and durable.
Designed to help caregivers with bathing and cleaning, a washing care robot works directly with water, so its water protection is a core design consideration from the start.
Lower limb exoskeleton robots such as Bear Adult, Rabbit Kid and Gait Assist are used in rehabilitation departments, neurology and intensive care units. They are cleaned between patients, and their electrical control systems benefit from proper sealing against moisture. This is one of the reasons Mona Care's lower limb exoskeleton robot range is built to a safety and reliability standard that suits demanding medical environments.
Patient transfer and mobility devices such as hug moving devices and wheelchairs are wiped down frequently, so easy-to-clean surfaces and moisture-resistant components matter for long-term use.
There is no single "best" rating. The right level depends on where the device is used and how it is cleaned:
When you compare products, ask the supplier for the specification sheet and check the IP rating of the electrical components, not just the frame. Remember that an IP rating describes the protection at the time of testing; it does not mean the device can be soaked in hot, soapy or salty water, which can degrade seals over time.
Understanding ingress protection helps you choose care equipment that is safe, reliable and easy to maintain. Whether you are equipping a rehabilitation department or setting up home care, checking the water protection of the electrical parts is a small step that pays off in the long run. Mona Care works directly with producers to offer genuine, quality life care products, and its team is happy to answer any questions about specifications and suitability.
