How The UMEK Window Cleaning Cart Delivers Spotless Results with Zero Residue

While you’re still struggling with water stains left after cleaning or frustrated by streaks on curtain wall glass, Hebei UMEK Environmental Protection Equipment Co., Ltd. has redefined cleaning standards with its self-developed window cleaning cart. Integrating advanced water treatment technology, this mobile cleaning system combines membrane separation technology and fluid dynamics design. It not only proves its technical strength with data but also delivers a cleaning experience that is residue-free, efficient, and widely compatible—a true fusion of technology and artistry.

The heart of the cleaning cart lies in its three-stage deep purification system, which performs a full purification “surgery” on each water molecule.
First, the raw water flows through a pre-filtration stage equipped with a CTO compressed activated carbon filter. Like a precision mesh, it removes large particles such as rust and sediment, while also adsorbing residual chlorine and organic contaminants—ensuring that the water quality entering the core system meets strict standards.
Next, the pretreated water passes through a reverse osmosis (RO) membrane module. Driven by external pressure greater than the osmotic pressure, water molecules pass through nano-scale membrane pores (0.1–0.001 nm), while calcium, magnesium, sodium ions, sulfates, colloids, and bacteria are rejected and discharged with the concentrate.
Finally, the RO product water (which still contains trace ions) enters a resin filter. Here, mixed bed resin further removes any remaining calcium, magnesium ions, and residual chlorine through ion exchange reactions.

Engineers Ares and quality inspector Adolph conducted detailed testing on carts with both single and dual membrane configurations. By precisely controlling inlet pressure, and using municipal tap water with a TDS of 650 ppm as raw water, the team achieved consistently stable 0 ppm output thanks to high-purity mixed resin.

These sophisticated technologies ultimately translate into three key user benefits:

Outstanding Cleaning Effect
Thanks to the 0 TDS ultra-pure water, vehicles cleaned with the UMEK cart require no manual drying—air drying alone leaves a mirror-like shine. Black car paint retains its rich gloss, and glass surfaces remain crystal clear without mineral deposits.

High Efficiency
The single-membrane model is ideal for households and small-scale use, while the dual-membrane version supports commercial cleaning needs. With a flow rate of 10–15 L/min, it enables uninterrupted operation and improves efficiency by over 3 times compared to traditional hand-washing methods.

Wide Compatibility
The system is compatible with municipal tap water, operates in temperatures from 5–40°C, and tolerates pH levels between 5–10. Its robust adaptability means a service life of up to five years (excluding filter media). The durable, corrosion-resistant metal cart with glossy finish is built for both indoor garage car washing and outdoor high-rise glass or solar panel cleaning—one cart for multiple uses.

Now, this high-performance, user-friendly window cleaning cart is ready for your evaluation—with visible technology and tangible value.
Choosing the UMEK cleaning cart means choosing a precise, efficient, and worry-free modern cleaning solution.
