Shark Matrix Plus Robot Vacuum and Mop vs Samsung POWERbot R7065

The Shark Matrix Plus is the better pick for most homes. It vacuums and sonic-mops, self-empties, and handles pet hair with a self-cleaning brush roll. The Samsung POWERbot R7065 is a dry-only vacuum with a low 3.8-inch profile that fits under low furniture, but it lacks mopping and self-emptying and its 3.7 rating trails the Shark's. Owners praise the Shark's suction and time savings, though some report hair collecting under the dust intake.

• Choose the Shark Matrix Plus if you want one robot that vacuums and mops, empties itself, and is built for pet hair on mixed floors.
• Choose the Samsung POWERbot R7065 if you only need dry vacuuming and a low-profile body that slides under low-clearance furniture.
