My last motor lasted exactly 20 years. I?d be happy to get the same out of this one.

Easy to install. Saved me a little $$$ ($100-$300 depending on where I buy it)

Even seems a little quieter.

Glad I researched and found you guys on-line.

Thanks!!!

Best price I could find on a replacement motor for our Central Vac. The motor was exactly the same as the original.

Vac works fine now.
