This guide provides an in-depth analysis of the differences between hydraulic elevators and vacuum elevators, helping you determine which offers better value for money.
What Is a Hydraulic Elevator?
Working Principle
A hydraulic elevator is a vertical lifting device powered by an electrically driven hydraulic system.
When upward movement of the car is required, the control system receives a call command and starts the motor to drive the hydraulic pump; the pump draws hydraulic fluid from the reservoir and continuously pressurizes it, thereby driving the plunger or piston upward to lift the car directly or indirectly.
When the car needs to move downwards, the control system receives a downward command and opens the oil return passage; the weight of the car and passengers then drives the plunger/piston down, while a throttle valve precisely regulates the hydraulic fluid flow rate to ensure a steady descent.
Key Features
Hydraulic elevators have a high load capacity and operate smoothly and comfortably with minimal vibration. Furthermore, thanks to over a century of development, hydraulic elevator technology is mature and adaptable to various building structures; additionally, the fact that the downward movement relies on gravity makes them safer to operate. However, hydraulic elevators typically have a short travel range, making them suitable only for installation in three- or four-story residences.
What Is a Vacuum Elevator?
Working Principle
Vacuum elevators operate based on the air pressure difference above and below the cabin.
When the elevator receives an upward command, the vacuum pump at the top extracts the air above, creating a low-pressure environment that allows atmospheric pressure from below to push the car upward. When the elevator receives a command to descend, the valve at the top opens to admit air, balancing the air pressure above and below; as the pressure difference disappears, the car descends naturally.
Key Features
Pneumatic elevators dispense with traditional cables, pulleys, and counterweights, relying instead on an open, cylindrical shaft to create an air-cushioned lift car. Vacuum elevators have a small footprint; the cabin is housed within a circular glass shaft, offering excellent visibility and a 360-degree panoramic view. In addition, vacuum elevators have a low load capacity and a short travel distance, but they are easy to install.

Cost Comparison
When costs are categorized into long-term and short-term components, hydraulic elevators have lower short-term costs, whereas vacuum elevators offer a cost advantage in the long run.
Hydraulic elevators: Their cost comprises three fundamental components—equipment costs, installation costs, and maintenance costs. The equipment cost for an economical hydraulic elevator ranges from $3,500 to $7,000, while the price of a standard residential hydraulic elevator is between $7,000 and $14,000.
The average installation cost for a hydraulic elevator is approximately $12,000, and the average annual maintenance cost ranges from $400 to $600.
Vacuum Elevators: Due to the technology not yet being fully mature and the limited number of manufacturers, vacuum elevators are more expensive than hydraulic elevators. Prices range from $15,000 to $18,500 for the basic model, and from $25,000 to $32,000 for a standard residential model.
Vacuum elevators have a relatively simple structure; the average installation cost is around $9,000, and the average annual maintenance cost is $350–$500. However, if replacement parts for the vacuum elevator are needed, they must be imported from the United States, Italy, Germany, France, or India.
Installation Requirements
First, regarding installation scenarios, hydraulic elevators are often suitable for installation in newly constructed or renovated residential buildings. Vacuum elevators are more suitable for existing residential buildings.
Secondly, vacuum elevators require minimal alteration to the building structure during installation. Hydraulic elevators require the construction of shafts and pits, which imposes certain civil engineering requirements on residential buildings.
Third, hydraulic elevators can be customized in size according to the available space on site to make them more suitable for installation. Vacuum elevators have fixed specifications.
Fourth, vacuum elevators are usually installed in living rooms and stairwells, while hydraulic elevators can be installed both indoors and outdoors.
Fifth, the installation cycle of vacuum elevators is short, and can be completed in as little as 2 days, while the installation cycle of hydraulic elevators is long, usually requiring 5 days.
Space Requirements
Vacuum elevators require less space than hydraulic elevators due to their smaller cabin design. In addition, vacuum elevators have built-in supports, eliminating the need for shafts, machine rooms, and pits. A few models of hydraulic elevators come with built-in supports, but most require a shaft and pit to house the machine parts.
Maintenance and Lifespan
Vacuum elevators are designed for a lifespan of 25-30 years, while hydraulic elevators are designed for a lifespan of 15-20 years.
Hydraulic elevators contain oily liquid and require custom inspections and replacements, making them more frequently maintained than vacuum elevators.
The main components of a hydraulic elevator to be maintained are the hydraulic pump station, hydraulic cylinders, valve groups, and control system. For vacuum elevators, the focus of maintenance is on the vacuum pump, sealing rings, and control system to prevent air leaks that could render the elevator unusable.
Overall, the maintenance costs of hydraulic elevators are higher than those of vacuum elevators.
Design and User Experience
Vacuum elevator: The pneumatic is more like a display item.
Vacuum elevators have a fixed shape and style, with limited design freedom. The main body is composed of circular glass, offering a 360-degree panoramic view, making them suitable for modern or futuristic residential decoration styles.
When riding a vacuum elevator, you will feel a slight change in air pressure. In addition, vacuum elevators produce more noise than hydraulic elevators.
Hydraulic elevators: Hydraulic elevators place greater emphasis on blending with the style of the house.
Hydraulic elevators offer a high degree of design freedom, and their shapes can be regular or irregular, such as horseshoe-shaped. In addition, families who want a wider view can also customize a sightseeing model—exquisite and compact, with a panoramic view.
Hydraulic elevators are classic, high-end, and luxurious, offering a wide range of materials and styles, with a focus on customization options to perfectly match your home.
Safety Features
Vacuum elevator: When there is a sudden power outage, the elevator slowly descends using the principle of air pressure balance until it reaches the lowest floor and opens the door.
Vacuum elevators have a relatively simple structure and do not have steel cables, so there is no problem of wear and breakage. Furthermore, multiple mechanical locks operate continuously during elevator operation to prevent the car from falling.
Hydraulic elevators: Hydraulic elevators have a natural advantage in preventing falls. When the elevator descends, it is driven by the pressure generated by its own weight, and the protruding hydraulic cylinder can directly lift the entire car, so it is not affected even if there is a power outage.
Hydraulic elevators have very mature safety devices, including speed governors, safety clamps, door interlocks, light curtain protection, and emergency stop devices, which prevent and protect the safety of users from all aspects.
In addition, hydraulic elevators can provide stable support and drive capabilities, ensuring safe operation even with heavy loads.
What To Consider Before Choosing?
Available Installation Space
First consider your available space to avoid the possibility that the purchased equipment cannot be installed successfully. The minimum footprint for a vacuum elevator is 0.45–0.70 ㎡, while the minimum footprint for a hydraulic elevator is 0.81–1.00 ㎡.
If installation space is limited, vacuum elevators have an advantage; if installation space is ample, hydraulic elevators offer more flexibility.
Home Design Style
Make the most suitable choice based on your home decor style. A classically styled residence is not suitable for installing a modern, high-tech vacuum elevator. Similarly, a futuristic residence is not suitable for a classic, luxurious hydraulic elevator.
An elevator that harmonizes with the residence can enhance the aesthetics and value of the house.
Customization Needs
If your reserved space is irregular, and if you prefer a home elevator with a strong sense of uniqueness, then a hydraulic elevator with strong customization features is more suitable for you.
Conversely, if you have standard reserved space and don’t have many special requirements for the style of the elevator, then a simple and elegant vacuum elevator is very suitable for you.
Budget and Long-Term Value
Budget and expected long-term value are also important factors influencing your choices. If you have a sufficient initial budget, you can choose a vacuum elevator, which can save you on future costs and has a long service life.
If the initial budget is limited, a hydraulic elevator is also a good option. Choosing a professional manufacturer through evaluation can also help you save on long-term costs.
In addition, if you are looking for long-term property display value, vacuum elevators have a greater advantage, while if you are looking for long-term functional value, hydraulic elevators are superior.
