Replacement Roller brush for my robovac
when you have long-haired dogs... these rollers WILL get tangled up with yards of hair...and although you can (and we do) take them out...and clean them off, after a while, the design of the roller is changed because of these tangles... This replacement roller is great, easy to install, and cost effective. would recommend if for no other reason, than keeping my house cleaner

Fits Perfect
This fits my cordless P10 Pro perfectly. It has some foam and hard grooves for picking up debris. The part feels very solid, not cheap or low quality at all. Be sure your Dreame is one of the models listed as this only fits those. It won't fit any of the other brands that share some of the Dreame parts (like Mova, for example). The rollers do eventually wear and reduce performance. This is a nice alternative to the name brand.

Perfect Fit & Performance
Style: with Pre-Filter
These are an excellent, cost-effective alternative to OEM parts. The brushes and filters fit securely, restore full suction power, and hold up well to daily use. A must-have for maintaining a Eufy RoboVac without the high brand-name price tag.

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!
