Verdict

The AR Blue Clean 3670 is a robust, 3-in-1 wet-dry vacuum cleaner and blower powered by a 1600-watt motor that generates a vacuum pressure of 19 kPa and an airflow rate of 37 l/s. It features a heavy-duty 30-litre stainless steel tank designed to efficiently collect solid debris and liquid spills across indoor and outdoor spaces up to 40 square metres. Main pros include its versatile functionality, a high-efficiency washable filter that protects the motor, a convenient drain plug for effortless liquid emptying, and high portability stemming from its lightweight 6.5-kilogram build with castor wheels. However, potential cons include its corded design which limits operational range based on power outlet proximity, its lack of variable speed controls to adjust the high suction power, and a bulky physical footprint compared to standard stick vacuums.
