What we like about Einhell TC-VC 18/20 Li S

  • Cordless freedom of movement via Power X-Change battery system
  • Lightweight and highly mobile with four swivel castors
  • Sturdy and rust-proof 20-litre stainless steel tank
  • Good suction power when paired with high-amperage batteries (4.0 Ah or higher)
  • Versatile integrated blowing function for hard-to-reach areas
  • Convenient on-board storage bracket for nozzles and accessories

What we don't like about Einhell TC-VC 18/20 Li S

  • Battery and charger are sold separately (Solo model)
  • Relatively short battery runtime (approximately 20 minutes on a 4.0 Ah battery)
  • Suction power drops noticeably if a low-amperage battery is used
  • Suction hose and extension tubes can feel stiff or cheaply made
  • Changing and cleaning the filters can be cumbersome and fiddly

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.
