I purchased a refurbished Robovac L50, and was excited to see if it was an improvement from my old 1s. Unfortunately the dust basket was missing a pin and that plastic screen that keeps the filter and foam in. I contacted the vendor, and Eufy responded quickly. The unit itself has laser guidance and a great app that lets you control it and set times, etc. It’s a definite evolution from the 1s. It is faster, cleans better, and allows you more ways to control it This is a great value for the money, especially for the refurbished price and the outstanding customer service.

Eufy beats the other guys in everything

Size: L60 Hybrid-renewed

We thought our old Eufy died so I ordered this since I always wanted the self-emptying model and the roller hair cutter was a big bonus since we have a chocolate lab that sheds a small bunny's worth of hair every day. Easy to set up, get added to the app, and just works. I will have to order more bags for the cleaning station, but overall very happy with this purchase even though the old Eufy started to work again right after this arrived.

Eufy vacuum

Size: L50 Hybrid-renewed

The device works really well. The battery doesn’t last that long which is a bummer but the product does what it states. I hope I don’t have to replace the battery yearly. My floors are clean tho and I have a dog and cat and multiple surfaces, all of which it cleans well even with difficult door thresholds.

I’m happy with it

Size: L50 Hybrid-renewed, Size: L50 Hybrid-renewed

Works great. Edit: After a week that I wrote works great, it had the issue that when it starts cleaning it looses power and shuts off after it leave the dock. When it disengages from charging it’s dead basically so unfortunately I returned it. But I will buy it again I was happy with it.

Charging base makes awful high pitch noise.

Size: L50 Hybrid-renewed

It cleans fine but the charging base emits a terrible high pitch noise. I have to unplug it when nearby. Cats no longer want to sleep in the same room as the vacuum base. Update: A little over a year later and it appears the vacuum's onboard wifi module has passed the rainbow bridge to electric heaven. Can no longer connect the L50 to the app or local wifi. Tried resetting, reverting to older version of app, changing my wifi to 2ghz only. Trying setup in airplane mode. Nothing works.
