It depends on your needs. The S1 Pro is worth it if you have thick carpets, pets, or need quality mopping. For hard floors and light-use homes, the E25 offers excellent value and will satisfy most basic cleaning needs.Which Eufy model is quieter?

The E25 is quieter, running at a background-hum level similar to conversation in the next room. The S1 Pro on high suction is noticeably louder, though both have quieter eco modes and most owners schedule cleaning while away.So you’ve decided a robot vacuum is the answer — no more guilt-tripping yourself about the dusty corner behind the couch. Smart move. But now you’re staring at two Eufy models and wondering: do I go for the fancy S1 Pro that costs roughly three times as much, or is the E25 secretly doing the same job in cheaper clothes
