Verdict

The DEWALT DXV20S is a corded, industrial-grade wet-dry vacuum cleaner featuring a powerful 1,050W (1.4 hp) motor that delivers a 37.8 L/s air flow rate and a 15 kPa working pressure. Built with a robust 20-litre stainless steel tank, this 5.1 kg machine excels at workshop cleanup through its dual suction and integrated blower functionalities, a large waterproof on/off switch, an integrated tank drain for seamless liquid disposal, and a smooth-rolling wheel setup. Key pros include its highly durable, lightweight housing, a washable and reusable cartridge filter, and excellent mobility, whereas its main cons are a relatively short 3-metre power cord and a 2.1-metre hose that limit its overall cleaning radius without an extension lead.
