Vacuum wet and dry dirt in and around your home with the Kärcher WD 4 P S V-20/5/22 (YSY). Thanks to the 20L capacity, the container won't fill up quickly and you can continue working for a long time. You can use the construction vacuum with or without a dust bag, so you can choose what suits your job. You can also connect tools to the construction vacuum via the socket. This is useful, because you can vacuum dust directly while working this way. See dirt in a hard-to-reach place? Easily blow it away with the blow function. You can hang the vacuum hose on the vacuum. This saves space when you store the construction vacuum. The stainless steel drum lasts a long time.
