Verdict

The Einhell TC-VC 18/20 Li S is a portable cordless wet-dry vacuum cleaner operating on the 18V Power X-Change battery system with a 3.5 kg lightweight design, an 80 mbar (8 kPa) maximum suction power, and a 72 dB(A) noise level. It features a robust 20-litre rust-proof stainless steel tank, an integrated blowing connection for hard-to-reach areas, four swivel castors for enhanced mobility, and a 36 mm diameter hose system measuring 1.5 metres in length. Main pros include its highly flexible cordless mobility, the versatility to handle both liquid spills and dry debris, a durable tank construction, and a convenient on-board accessory holder for the included crevice, upholstery, and combination nozzles. However, it is typically sold as a bare tool without the required battery or charger, lacks a power tool take-off socket, has no speed regulation adjustment, and some users note that the plastic extension pipes and included cleaning accessories can feel somewhat flimsy.
