Perfect Fit for Eufy E25 - Great Way to Refresh Your Vacuum
Size: Eufy E25 Omni / E28 Omni E28
This replacement kit worked perfectly with my Eufy E25 robot vacuum/mop. All of the parts fit as expected, and it was nice to be able to swap everything out at once rather than replacing pieces individually. After installing the new brush, mop, filters, and other components, my machine is running noticeably better. Super easy to do. The set includes a good assortment of replacement parts, making it a convenient way to refresh your vacuum and keep it working efficiently. A great value and an easy way to extend the life and performance of your robot vacuum.

Complete Replacement Set
Size: Eufy E25 Omni / E28 Omni E28
This replacement parts kit is a convenient way to keep a compatible robot vacuum running efficiently without having to source each component separately. The included rolling brush and side brushes help maintain strong cleaning performance by picking up debris effectively, while the filters support proper airflow and dust capture. The dust bags are a useful addition for keeping the self emptying system working smoothly over time. The roller mop also fits well and helps maintain the mopping function without needing frequent replacements. Having a full set like this makes routine maintenance much easier and helps extend the overall lifespan of the vacuum.

Mop won’t lock and black roller won’t fit
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
We’ve had our E28 for about a year now, so it was time to change out some of the more worn parts. This kit looked to have everything I wanted to swap out. It came with two sets of sweeper brushes, two center brushes, the roller mop brush, two dust bin filters and several disposable dust bags. I was able to get all of the parts to fit on our E28 except the black side main brush. It looks like the diameter of the hole isn’t correct for the model, but the grey side was (see photos and video comparing this set to factory set). The roller mop looked very similar except it had a slightly less high pile. The pieces all seemed good quality over all. Putting the new parts on was easy otherwise and they fit well. I sent out our E28 for a whole house cleaning and it did well both vacuuming and mopping, or at least on-par with the factory parts with the same noise level. The aim issue was that the roller mop wasn’t locking in place, and when it went to try to wash the mop and popped the whole vacuum out of its base cradle and threw an error a couple times throughout the cleaning. I just had to manually push the roller mop back in and it worked fine until the last wash and then I couldn’t get it to stop throwing the error. So, 2/5 stars for the one piece not fitting and the roller mop having issues during the mop washing process. Guess I’ll have to order from Eufy directly.

Direct replacment for omni E28!
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
This kit is an excellent value and contains direct replacement parts for the Eufy E28 Omni. Everything in the box from the rolling brush and the roller mop to the filters and dust bags matches the original components perfectly in size and fit. ​I found that the side brushes and the main roller installed easily without any forcing, and the vacuum performance remained consistent with no loss of suction or strange noises. The HEPA filters fit snugly in the housing, and the dust bags slide right into the docking station just like the brand-name ones. It is much more cost-effective to get this entire bundle than to buy these items individually. If you need to refresh your E28 Omni, this set is a reliable way to get it back to peak performance.

Works Perfectly
Color: 12PCS side brushes for Freo X Ultra/Freo Z Ultra/Freo X Plus
The side brushes work perfectly in my robot vacuum and mop and are a better price than the brand replacements. I'm happy with my purchase.
