eufy S1 Pro vs Omni S2

The eufy Omni S2 and eufy S1 Pro are both high-end vacuum-and-mop combos with similar designs, but the older S1 performs better overall. It picks up more debris on bare floors, and its roller mop clears dried-on stains much more effectively. The one place the newer S2 has the edge is when it comes to adapting to your household's layout. It cleans around furniture more smoothly and clears slightly taller thresholds. The S1 Pro spots and avoids small items on the floor slightly better, but both handle most clutter well. Neither is ideal for plush carpet or shedding pets. The S2 also adds a fragrance diffuser, but its scents are strong and chemical-smelling, so most people can skip it.
