Samsung SC4470 vacuum cleaner with a Karcher VC 6 motor

Bagless Samsung SC4470 vacuum cleaner with a Karcher VC 6 heart (corded model). 3500 dinars. The automatic cord rewind mechanism does not work. The motor has been replaced with a serviced Karcher VC 6. This motor uses about three times less electricity than the original motor, but has almost the same suction power (300 watts now instead of the 370 stated by Samsung). The vacuum cleaner has been cleaned inside and out. The brush shows signs of use. Belgrade, Zvezdara.
