A roller mop robot that also gives you a portable carpet and upholstery cleaner in the dock. Vacuum Wars measured 85% sand pickup, a strong 127 stain score and 23 of 24 obstacles avoided. Long hair tangles badly, so skip it if your household sheds long hair.

A good fit for busy homes with carpet, pets and clutter on the floor, since it was the only robot here to avoid all 24 obstacles in Vacuum Wars testing and it never tangled hair. Mopping is fine for daily grime but several reviewers found it weak on tough dried stains. Skip it if stain removal matters most or if you mind paying for Eufy's own detergent and fragrance refills.
