Works great!
Style: with Pre-Filter
I bought this set to put on my original euphy robot vacuum. It works perfect! All pieces fit perfectly and were so easy to change out. Iโ€™ve had the new parts installed for a few weeks and it works so much better now. I recommend them for sure if you need any new parts for yours!

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 Eufyโ€™s but for the value you do get a lot of product. So only 4 stars but just for the brushes โ€œappearing 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 isnโ€™t clogging it. Also, replacing the spinning brush quieted it down significantly, it sounds like new again.
