One To Avoid

SUPERLEX Cordless Window Vac Rechargeable, 3-in-1 Window Cleaner

Not Recommended

We tested the SUPERLEX Cordless Window Vac, and while it offers some convenient features, it falls short in critical areas, making it hard to recommend.

Why We Don't Recommend This Product

• Water Leakage (Critical): The device exhibits persistent water leaks during normal operation, which defeats its primary purpose of removing water without mess. This creates additional cleaning work rather than solving the window cleaning problem.
• Inadequate Suction Power (High Severity): Suction power is insufficient for removing condensation and water droplets effectively, particularly on larger or wetted surfaces. Results in subpar cleaning and incomplete drying.
• Excessive Noise (Moderate Severity): The motor produces notable noise during operation, suggesting potential design or manufacturing defects. This detracts significantly from user experience, especially for morning/evening cleaning tasks.
• Insufficient Tank Capacity (High Severity): The 60ml water tank is substantially smaller than competitors, requiring constant emptying mid-task and making it impractical for anything beyond small-scale cleaning.

Specification	Value
Battery Capacity	1500mAh
Battery Runtime	30+ minutes
Water Tank Capacity	60ml (inadequate)
Cordless	Yes
3-in-1 Functionality	Yes (but poorly executed)
Reliability Rating	Below average

The cordless design and 2-in-1 water tank system are well-conceived. Being able to spray and vacuum without additional tools is handy, and the rechargeable battery allows for some freedom of movement.

On smooth surfaces like mirrors and tiles, it delivers a streak-free finish, which is one of its better qualities. However, the negatives overshadow these positives. The small water tank quickly fills up during use, requiring frequent emptying, which interrupts the cleaning process.

The suction power, while sufficient for light tasks, struggles with heavier dirt or larger surfaces. Additionally, it's noisy for such a compact device, which detracts from the overall experience.

Perhaps the most frustrating issue is its tendency to leak water during use, leaving behind more mess to clean. For a product designed to simplify window cleaning, this flaw makes it impractical for regular use.

While there are some redeeming features, the SUPERLEX Cordless Window Vac is ultimately a disappointment. If you're looking for a reliable cleaning tool, we'd suggest exploring other options. This one misses the mark.

Better Alternatives: For budget constraints, consider the DOVAMAN WC01A. For mid-range options, the Tower T131000BLG RWV20 or Kärcher WV 2 Plus N offer far superior reliability. For premium performance, the Vileda WindoMatic Power is the clear choice.

How We Evaluated and Chose the Best Window Vacs on the Market

When determining the best window vac, we didn't just clean windows and call it a day. We explored every feature and functionality that matters to you, ensuring a thorough and unbiased evaluation. Here's how we did it:

Performance Testing

Performance is the backbone of any window vac. We started by testing suction power on a variety of surfaces, including windows, mirrors, shower screens, tiles, and car windows.

To measure efficiency, we timed how quickly each vac removed condensation and grime while checking for streaks or residual moisture. Versatility was another key factor—could the vac handle different surface types seamlessly?

To ensure thorough testing, we compared results with and without cleaning solutions, noting how well each model performed in delivering streak-free results.

Ease of Use

A great window vac should be effortless to use. We assessed the ergonomics of each device, focusing on handle comfort, weight distribution, and overall balance during extended use.

Flexibility played a significant role—how easily could the head or neck manoeuvre around tight corners, edges, or high spots? Additionally, we evaluated the water tank for ease of detachment, emptying, and cleaning. Models prone to leaks or spluttering, when the tank was full, were noted for improvement.

Battery Life and Charging

Battery performance is vital for uninterrupted cleaning. We tested runtime under continuous use to identify how long each vac could operate before needing a recharge. Any noticeable drop in suction power as the battery depleted was noted.

We also timed the recharging process and verified the accuracy of battery indicators, ensuring you always know how much power is left during tasks.

Build Quality and Durability

Durability is crucial for a long-lasting tool. We examined each vac for the quality of its materials, paying attention to sturdiness and resistance to wear and tear.

Durability tests included simulating accidental drops from a reasonable height and using the vac repeatedly over several days to evaluate its resilience. Models that cracked, flexed, or showed signs of weakness were marked down.

Extra Features

Some models came equipped with additional features that added significant value. We thoroughly tested adjustable suction modes, interchangeable nozzles, and LED battery indicators to ensure these extras worked seamlessly.

Accessories like spray bottles and microfiber cloths were evaluated for their practicality and convenience, helping to determine whether they truly enhanced the cleaning process.

Noise Levels

Noise can be a deal-breaker for many users. Using a decibel meter, we measured noise output during operation to compare sound levels across models. Quieter devices were rated higher for offering a more pleasant cleaning experience without unnecessary disturbance.

Price and Value

Finally, we compared each vac's features, performance, and durability against its price to ensure value for money. Premium-priced models underwent extra scrutiny to confirm that their higher cost was justified by superior performance or innovative features.

Budget-friendly options were assessed to ensure they still delivered reliable cleaning results.

Frequently Asked Questions

Can I Use a Window Vac in a Shower?

Yes, you can use a window vac in a shower. All recommended window vacs excel on smooth bathroom surfaces including shower screens, tiles, and mirrors. Their powerful suction effectively removes water, condensation, and moisture, leaving surfaces completely dry and streak-free. The Kärcher WV 2 Plus N and Vileda WindoMatic Power are particularly praised for shower screen performance.

Can I Use Vinegar with a Window Vac to Clean Glass?

Yes, window vacs work effectively with various cleaning solutions including vinegar-water mixtures, commercial glass cleaners, and proprietary solutions. However, always wipe surfaces with a cloth before using the vacuum to distribute the cleaning solution evenly. The spray bottle included with most models makes this process seamless.

Do Window Vacuums Only Clean Glass?

No, window vacuums do not only clean glass. They are versatile tools that can clean a variety of smooth surfaces, including mirrors, tiles, shower screens, and even countertops.

Can Window Vacs Clean the Window Screen?

How Long Does a Typical Window Vac Battery Last Per Charge?

Battery runtime typically ranges from 30 to 40 minutes on a single charge, with the Vileda WindoMatic Power providing the longest coverage at 120 m² (approximately 40 minutes). The Kärcher WV 2 Plus N runs for 35 minutes covering 105 m². Most models provide sufficient runtime for cleaning multiple windows and surfaces in one session before requiring recharge.

Are Window Vacs Suitable for Cleaning Car Windows?

Yes, most models including Vileda WindoMatic Power, Kärcher WV 2 Plus N, and DOVAMAN WC01A are explicitly suitable for car windows and outdoor glass surfaces. Their cordless design and powerful suction make them ideal for vehicles and exterior applications. Ensure you're holding the device vertically or horizontally as appropriate to prevent water leakage.
