Decent Accessory Kit
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
This is a decent accessory kit I got for my E28! This kit comes with so many of the parts I needed to keep my E28 up and cleaning well. The accessories each fit my bot very well - the roller brush slid on with no issue and it didnt bind in any way. The knap on the brush is decent (a bit knappier than the OEM). This is nice because I have textured tile so a better knap will help clean inside the nooks and crannies. The kit comes with a lot of the needed items for the bot.
One negative (but I didnt take away a star because this can happen in others as well) was that the cardboard on the dust bag didnt have enough glue to keep the bag on the stock board - it tore away super easily which was a bummer to lose a whole bag. Not the end of the world, but be carful inserting the bag properly to avoid tearing it away/open.
All in all this is a decent kit and is a fraction of the price of others. Additionally, it is one of the least expensive kits on Amazon, which is nice - because we all could stand to save a buck or two.

Eufy Replacement Parts
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
The 14-piece replacement parts for the Eufy E25 Omni made a huge difference. It came with a roller mop, roller bushes, air filters, and dust bags. I hadn’t replaced any of my parts for quite a while and the vacuum was starting to not work very well. I ordered this set hoping for the best and was really impressed by the quality of the parts. Everything worked beautifully and installation was a breeze. After just a few seconds I replaced everything that needed to be changed and was scheduling for a cleaning. The new parts made a big difference in how well the vacuum performed and I couldn’t believe how much cleaner the floor was. I am totally happy with my order and will continue to use these parts.
