Releasing aromas: Enjoying wine is all about aromas. It’s the same joy as smelling bacon frying or sniffing a hot cup of Chai tea. With wine, the aromas are released as the alcohol volatilizes from the surface of the wine. Having an increased surface area is a benefit to optimize releasing aromas while drinking. There have been studies to show how swirling wine increases surface area.

Improved safety: In any kind of work, labour-intensive lifting and carrying of heavy objects make people susceptible to Musculoskeletal Disorders (MSDs). A substantial proportion of MSDs was due to back pains. However, the usage of trolleys and hand trucks, wherein loads are pushed or pulled, decreases the incidence of such injuries.

No Compromise on Suction: Traditional vacuum cleaners rely on filters and bags to trap dust and dirt. Air filters, in theory, should catch the dirt and dust, only allowing purified air to flow through. However, bags and filters clog over time which reduces the vacuum’s cleaning performance and degrades the exhausted air quality. As water never clogs, water filtration vacuum cleaners never lose their suction.

The first disadvantage is that they are disposable. Recently, CO2 cylinders can be purchased for about 200 yen per cylinder, so the cost is not that high, but compared to portable pumps that can be used forever until they break, the cost performance is not so good. Also, as for the amount of luggage, portable pumps are getting smaller and smaller these days, so the size is not that much different compared to the size of two CO2 cylinders and an inflator in the front and back.

Simpler design: Hydraulic and pneumatic actuators can have many more parts within their system than an electrical actuator, and they can be much more complicated to incorporate into your design. The simpler design of electrical actuators results in savings in terms of design and maintenance because of lower initial and ongoing costs, higher reliability, and fewer spare parts to stock in the case of needed repairs.
