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. I’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 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!
