Eufy dropped the ball on this vacuum
Style: L50 SES
I’ll start by saying the reason I purchased this vacuum, is because I have a Eufy 25c robot vacuum that is very dependable. I decided I wanted an upgrade because the 25C was great for cleaning, but I had to empty it way too often. I just knew I would love the L50 SES. I thought it was just what I was looking for a self emptying robot vacuum with a 60 day fill capacity. Allowing 2 months before I needed to touch my vacuum. Here’s where things went wrong. I never got a chance to test the vacuum because it wouldn’t connect to my WiFi and I tried everything. Now this wouldn’t have been a problem if the L50 came with a remote control like the 25C. Unfortunately I had to rely on the App and since the L50 couldn’t connect to my WiFi, I couldn’t control the vacuum. The reason I gave 2 stars is because the customer service at Eufy is awesome. I was given the option to replace the vacuum with a new one but after researching the L50 i decided to return it for a refund. Apparently this model has a defect, because I found so many negative reviews about the same issue with the same model. The thing is I never read reviews because I have a Eufy smart scale, 25C robot vacuum and an Eufy security system and everything works perfectly. So in the end I purchased a Shark Matrix Self emptying robot vacuum and a Shark self emptying stick vacuum. If Shark’s vacuum preforms well, Eufy might have lost a valued customer. I hope this review helps someone make a informed decision. By the way Eufy self emptying vacuum needs replacement bags and the Shark Matrix robot vacuum doesn’t need bags. I will say the suction and design on the Eufy L50 SES was great.

Much better than the old model.
Style: L50 SES
I had an old s11 that finally died. This one is much better. It maps the house and follows a snake pattern. Once the mapping is finished you can select what rooms you want to clean. I like the self emptying feature. Plenty of battery life.

Good performance, flaky Wi-Fi connection
Style: L50 SES
The L50 physically works great - it does a good job of picking up dust and dirt at the end of the day. The pathfinder and route planning algorithm is fairly efficient at determining the best way to clean a room. Sometimes it kicks around bits of dust with its spinning brush without picking it up, but it's not often.
What has been terrible, however, is the Wi-Fi support. Since our provider disabled 2.4 GHz support from their router modem without notice, I use a Mac Mini to supply the 2.4 GHz signal, and even though the Eufy is next to it and my phone gets full signal strength, it still can't connect to it half the time. After it fails to connect, it needs to be restarted or even reset to try to get the connection again. Support doesn't seem to be helpful in offering a solution.

Perfect Replacement Roller Mop for Eufy Robot Vacuum
This replacement roller mop fits perfectly and works just like the original. Installation was quick and easy, and the quality feels durable and well-made.
It does an excellent job picking up dust and light debris while providing consistent floor cleaning performance. The roller is washable, easy to maintain, and holds up well after multiple cleaning cycles.
I appreciate that it restores the robot’s cleaning effectiveness without any compatibility issues. If you own a compatible Eufy model and need a replacement, this is a reliable option that keeps your robot performing at its best.
Highly recommended for maintaining optimal cleaning results.
