Parts fit my Eufy like they should. The side brush has held up nicely.

Bang for buck
Size: 11SMax-24Pack
You get a lot for the price. And it fits. Recommended. It is a little noisier than the original bit functions are the same

Works great, easy to setup. It's my second unit for the basement level. Picks up all the fur from a large Rottweiler and a small Rat Terrier.

Not worth it
Style: L50 SES
Worked great for 5 months and then the WiFi connectivity stopped working rendering the vacuum useless. Because it’s refurbished it was past its warranty and the company refused to do anything about it other than offer a discount on a product that cost four times as much even after the discount.
