Very good Value for replacement part and reliable
Style: with Pre-Filter
Very good product for the price - the front brushes wear fast compared to the original Eufy’s but for the value you do get a lot of product. So only 4 stars but just for the brushes “appearing to not last as long and bend but the buy is worth the extras. The filters look and work identical to the OEM. Good stuff - thanks!

Perfect fit, 11s running like new!
Style: with Pre-Filter
All parts fit perfectly. My vacuum lasts about 20 min longer since the filter isn’t clogging it. Also, replacing the spinning brush quieted it down significantly, it sounds like new again.
