Tapo RV20 Max Robot Vacuum vs Shark ION Robot Vacuum R75

Buy the Tapo RV20 Max if you want one robot that vacuums and mops, with strong suction and long runs. The Shark ION R75 is a simpler dry-only vacuum that charges faster and sits lower under furniture. The Tapo wins on features and suction; the Shark wins on simplicity and a lower profile. Owners of both report the usual robot limits: hair tangles in the brush and mapping is basic on the Shark.

• Choose the Tapo RV20 Max if you want vacuuming and mopping in one robot, high suction for pet hair, and app features like no-go zones and scheduling.
• Choose the Shark ION R75 if you only need dry vacuuming, want a low-profile robot that fits under low furniture, and prefer a quick-charging, no-frills setup.
