Worked for over 10 years. I completely disassembled it, cleaned it out 2 kg / g ., lubricated wd-40, hung it in place. Can be cleaned without removing from the wall. Pull the impeller towards you, it comes off the rod and everything is ready for cleaning. Parsing to the rotor is described below in the reviews, not very difficult. Italy is written on the motor. I recommend to all. All relatives work with several pieces, bought at different times. WD-40 washes out the grease from the bearings, starts to ring softly. Do not use.
