3rd-Gen Hand held Vacuum Pump VM4: Crafting Ingenious Quality from User Feedbacks
When the Hand held Vacuum sealer VM2 gained market recognition for its portability, we have always regarded every user suggestion as a driving force for progress. Today, the 3rd-generation upgraded model, the VM4 Hand Held Vacuum sealer which has undergone numerous design adjustments, mold optimizations, and production refinements, makes its official debut. This new product is not only an iterative version of the VM2 but also a profound response to user needs. Every upgrade, from appearance and core functions to energy efficiency details, accurately addresses the pain points of the previous generation, aiming to provide a more tailored vacuum preservation solution.
We first focused on the most intuitive user experience feedback, making improvements in both appearance and operational safety:
More Elegant Appearance: In response to Vacuum Pump VM2 users' suggestions for optimizing the body proportion, the VM4's body height was repeatedly adjusted during the design phase, ultimately presenting a more slender and smooth outline. This modification not only eliminates the bulkiness of traditional small home appliances, making it more stylish when placed on the kitchen countertop but also saves space when stored in a handbag;
Mis-touch Prevention: Addressing the common market pain point of "one-touch activation" – many users have experienced idle operation, power waste, and machine damage due to accidental touches – the VM4 is equipped with a "2-second long-press for power on/off" mechanism. This fundamentally avoids the risk of mis-touch, allowing users to operate without worrying about "unintentional activation".
The Electronic Vacuum Pump VM2's "damage-free water extraction" design has been recognized by users, but there are still two pain points to resolve: the need for manual monitoring of the water tank level and water splashing during extraction. The Electronic Vacuum Pump VM4 provides targeted solutions:
A dedicated flat gasket and matching tube are added to the original design: The flat gasket has a built-in intelligent water level sensor, which automatically triggers a shutdown when the water tank is full, fundamentally preventing water from seeping into the machine and causing damage. The matching tube optimizes the water flow path, completely solving the problem of water splashing, turning water extraction from a "constant monitoring task" into a "set-it-and-forget-it process".
We delved into users' potential needs for "preservation effectiveness" and "battery durability", achieving breakthroughs in core performance and energy efficiency:
Stronger Vacuum Power: The negative pressure value is increased from -35Kpa (VM2) to -40Kpa (VM4). With stronger vacuum extraction capability, it can more thoroughly remove air from the packaging bag, slow down food oxidation and deterioration, and further extend the preservation period compared to the previous generation;
More Energy-Saving Standby: The automatic shutdown logic for inactivity is optimized, reducing the time from 3 minutes (VM2) to 30 seconds (VM4). This prevents power waste during long periods of standby, making it especially suitable for scenarios like outdoor camping and effectively extending the usage time per charge.
"Not knowing the remaining battery level" and "not knowing how long the vacuuming will take" -these two frequent feedback points have become key directions for the VM4's function upgrade. We innovatively added a dynamic display function:
During vacuuming, the screen displays the remaining time in real-time, allowing users to accurately track progress without repeated checks;
After the vacuuming is completed, the display automatically switches to show the remaining battery level, clearly indicating the power status. Whether used at home or during outdoor trips, users can plan their usage in advance, completely eliminating the anxiety of "unknown battery level".

| Fluid collection cab | Yes, fluid vacuuming adaptable | Yes, fluid vacuuming adaptable |
| Drain cleaning function | Yes | Yes |
| Water pumping without machine damage | Yes | Yes |
| Air Release Valve (or Solenoid Valve) | Yes,it has a solenoid valve that releases pressure after vacuuming, and the vacuum nozzle will not be adsorbed on the plastic air valve. | Yes,it has a solenoid valve that releases pressure after vacuuming, and the vacuum nozzle will not be adsorbed on the plastic air valve. |
| Bag vacuming speed | The VM4 is an 8L pump, while the VM2 is a 3.5L pump. For bags of the same size, the VM4 vacuums air faster, cutting the vacuuming time in half. | |
| Blue LED Display or LED Display Lends | Use 4 LED lights to display power and charging status | LED display lens shows the vacuuming progress time by seconds in real time during operation, and automatically switches to show the remaining battery volume once vacuuming is done.It shows LO for low battery and flashing % marks incidates charging. |
| Fluid exit tube | No tube, machine can not install the tube, the liquid will spray out directly. | Yes,fluid tube exit marinated fluid out of machine and dismiss odor. |
| User Controlled Negative pressure | No | It is used to control the intensity of the negative pressure to avoid deformation of fragile objects such as fruit, toast, etc. Operation: Press and hold the power button when vacuuming, release it when the desired negative pressure is reached. There is no need to vacuum to the set maximum negative pressure. |
| Fluid shut sheet | No | The VM4 features a spring-loaded waterproof silicone sheet to prevent water that hasn't entered the machine from flowing back onto the plastic valve or bag when vacuuming stops, or only allow a small amount of water dropped on the plastic surface. This also provides better protection against water damage to the machine. This waterproof structure is patent-pending. |
| Auto shut off | No work 3 minutes shut off | No work 30s shut off |
From collecting user feedback on the Vacuum Pump VM2, to determining each upgrade direction for the cordless handheld vacuum sealer VM4, and then to design sketches, repeated mold modifications, and production line debugging – every step of the Vacuum Pump VM4's development has undergone days of refinement. We firmly believe that a good product is not about "quick replication" but "thoughtful response to needs". The 3rd-generation handheld vacuum Pump VM4 centers on user needs, addresses real pain points through detailed upgrades, and transforms every vacuum preservation experience from "barely usable" to "effortless and enjoyable".
