Key specs

Suction: 30,000 Pa (eufy claim)
Mopping: HydroJet 2.0 self-cleaning roller mop
Self-emptying: Yes
Plumbing: Optional auto refill and drain kit

Our verdict

A strong flagship if you want the plumbing option and big suction. If mopping is your priority, the cheaper C28 scored better in that area.

What we like

Vacuum Wars found better carpet cleaning than the previous S1
Highly rated obstacle avoidance
Can connect to household plumbing so you never fill tanks

What to know

Vacuum Wars measured weaker mopping than its predecessor
Priced against Roborock and Dreame flagships with longer track records
