The capacity is way overstated. Based on the weight of the battery and the lifespan right out of the box, this is a very poor quality battery. It performs worse than the "worn out" one it was supposed to replace.

Great value for the cost seems like the vacuum runs longer than it did with the original battery

The Robit R3000 is only one of many brands using identical internal hardware so any parts you need are readily available.The additional power this battery has compared to the original battery makes for much longer running times - to the point that my Robit becomes annoying after running for much longer than it did when new.Be aware, to store this battery the manufacturer recommends storing it fully charged.HIGHLY RECOMMENDED

My ionvac smart clean 2000 was only running 9 mins with a full charge. the manufacturer battery was only 2600 mah this is 3500mah. charge time does take longer due to increased battery size. does fit a bit tight but is able to fully close the battery compartment. tested for 2 days now. getting about 80mins of total run time compared to 9 mins. seems to be working good as of right now. happy with purchase.

My Eufy G30 stopped running for more than 5 minutes. Checked online and it figured it was the battery most likely. Ordered this because the reviews looked ok and wanted to see if a larger battery would help. The vacuum works now. It does take a lot longer to recharge, but I haven’t noticed it run longer when cleaning. So far it’s working. We’ll see how the performance goes as time goes on.

Battery fits pretty tight in battery housing of Eufy 11s but works really well. Ran for roughly 1.5 hours on first charge. So far so good. Will update review if performance doesn’t hold up reasonably.
