I’ve had this little vacuum since 2019 (~7 years at the time I’m writing this).
I replaced the batteries a couple of years ago and more than doubled the runtime when it was new. I had to take the battery apart and weld new cells in, it’d be nice if they sold replacement batteries.
In the last few months, it’s started making a terrible squealing noise with no suction. The squeal will go away if I bump the vacuum really hard or turn it on and off several times in a row, but it’s been getting worse requiring more bumps or on/off cycles.
I finally got around to taking the vacuum apart again, and the brass bushings on the motor are shot. I suspect you could extend the life of the vacuum by putting some oil on the bushings once a year but mine are too far gone for that.
The motor is labeled:
Leshi Motor
LS-545PC-63483
14.4V
180120/C
I was not able to find that part number for sale anywhere.
Here are the dimensions of the motor:
The motor is apparently a standard size overall “rs-545”, but this motor has a very long shaft. It looks like most of the motors sold in this size have a ~8mm long shaft. I think you could JUST get away with using a motor that has a 15mm shaft, but 20-30mm would be better. This motor from eBay for ~$12 including shipping (vmotor v060268), has been working fine for a week in the vacuum.
I did drill a hole in the motor shroud so I could get to the end bearing without complete disassembly, I think the front bearings are JUST reachable with the shroud on. Hope this motor lasts at least as long as the first one did!
