Shark Matrix Self-Empty Robot Vacuum vs Shark ION Robot Vacuum R75

The Matrix is the better pick for pet owners and anyone who wants to stop emptying a bin by hand. It self-empties into a dock, has a low 4.19 in profile, and Shark claims 50% more suction than the iRobot i3. The ION R75 is lighter, quieter, runs up to 60 minutes, and has a true HEPA filter, but it lacks self-emptying and its 2.6 in height is its main edge for sliding under furniture. Owners of both report the usual robot-vacuum trade-offs: good daily pickup, weaker deep-cleaning than a full upright.

• Choose the Shark Matrix if you have pets or heavy shedding and want the vacuum to dump its own bin for weeks at a time.
• Choose the Shark ION R75 if you want a light, quiet, HEPA-filtered vacuum for everyday upkeep on carpet and tight under-furniture spaces.
