Product Sheet
Product Manual
The Einhell TC-VC 1820 S wet & dry vac is a powerful helper with a 1,250 W rating for in-depth and thorough cleaning jobs. A wet and dry vacuum cleaner provides good service for the careful cleaning of surfaces that are not sensitive to water.
For household work, for carpets or fixed textiles, tiles or all types of glazed tiles with open pores, normal surface cleaning alone is often not enough. A wet & dry vac can also be used for cleaning the insides of all kinds of vehicles, right to the tips of the textile material, be it seats and roof linings or mats and interior trim.
The wet & dry vac from Einhell is equipped with a rust-proof and sturdy stainless steel tank with a capacity of 20 liters. The hose system with a diameter of 36 mm maintains high air and dirt flow. The blow connection is for blow-cleaning hard-to-reach areas such as in awkward corners or behind solid cupboards.
For easy transport and flexibility in use there are castors. For tidiness during use there is a practical accessories holder and a cable holder on the housing.
The product is supplied complete with a 1.50 m plastic suction hose with three-piece extension tube, a floor nozzle for carpets and smooth flooring along with a crevice nozzle, plus a foam filter, a blue filter bag and a paper dirt bag, so that nothing stands in the way of getting started right away.
