Verdict

The WORX WX031.9 is a 20V cordless wet-dry vacuum and blower featuring a high-efficiency brushless motor that delivers up to 16 kPa of suction power and an airflow rate of 1.1 m³/min. It offers a versatile 2-speed operation, an 8-liter dry dustbin capacity, a 3-liter liquid capacity, a 2-meter extendable hose, and a washable HEPA filter. Main advantages include its portable, 3 kg lightweight design, integrated shoulder strap for effortless carrying, and seamless compatibility with the Worx PowerShare battery ecosystem. However, a notable con is that this specific model (.9) is sold as a bare tool without the required battery or charger included, and its bulky body can make reaching tightly confined spaces somewhat difficult.

Fantastic, powerful suction for cleaning dry debris, sawdust, and wet spills
Versatile multi-functionality, serving as a wet/dry vacuum and a blower
Large-capacity dust bin that holds plenty of rubbish and water
Compatible with the [WORX PowerShare System](https://uk.worx.com/20v-cordless-brushless-compact-wet-and-dry-vacuum-cleaner-with-4-0ah-battery-charger-wx031/), allowing you to use existing 20V batteries to save money
Compact and lightweight with an included shoulder strap for good portability around the workshop or jobsite
Useful for connecting directly to other power tools (like sanders) for dust extraction

What customers dislike about WORX WX031.9?

Filter requires frequent cleaning to maintain peak suction and performance
Battery drains quickly in full-power mode, making larger capacity batteries almost a necessity
Included shoulder strap is not very comfortable, and the weight can become noticeable over time
Sold as 'body only' (or bare tool), meaning batteries and charger must be purchased separately
Flexi-hose can occasionally slip out or become clogged with larger pieces of debris
Hose length is sometimes too short for deep cleaning inside vehicles

Summary of the review

Worx Cordless Compact Vacuum Cleaner tried & tested by car advice experts

The Parkers review highlights the Worx Cordless Compact Vacuum Cleaner as a robust, well-built tool featuring a unique design with a high-capacity dust bin, a convenient extendable hose, and efficient 20V PowerShare battery compatibility. While praised for cleaning multiple vehicles, the device is criticized for a poor-quality shoulder strap, occasional hose clogs with larger debris, and a filter prone to trapping fibrous dirt, making it best for general rather than heavy-duty cleaning.
