The rails look perfect BUT the description of replacing them with the N79S is very misleading due to the supposed simplicity. In fact, this vacuum cleaner model has to be almost completely disassembled to access the wheels. All YT videos are for different models with MUCH easier wheel access. Most people trying to replace the Debit N79S will find themselves left with a bunch of screws and small parts that they'll never figure out. When it got to the point where I had to rip the wiring out of the motherboard to get to the next screw, I was all set. Maybe I'll try again, just for a smile, when it's time to send the vacuum cleaner to the big robot junkyard in the sky and I've got nothing to lose.
