The thinkstar 3-in-1 is a low-cost robot that sweeps and wet-mops at the same time, with drop and collision sensors, automatic recharging, scheduling and remote or app control. It is aimed at small apartments and hard floors rather than whole-house carpet cleaning. Against established rivals like Roomba, Roborock and Eufy, it lacks the suction power, self-emptying base and reliable mapping those models are known for. Treat it as a basic starter robot for light daily upkeep, not a deep cleaner.

Owner feedback on budget robots of this type is mixed. People like the hands-off daily dusting and the stair sensors, but many find the suction weak and the navigation random.
The thinkstar 3-in-1 Robot Vacuum Cleaner is a cordless robot that sweeps and wet-mops floors at the same time. It removes dirt, pet hair and debris from hard floors and carpet.
Smart navigation maps the space and plans efficient cleaning routes. Drop sensors help it avoid stairs, and collision sensors help it avoid furniture. It has multiple cleaning modes for different cleaning needs.
The robot recharges automatically and can be scheduled to clean. You can control it with a remote or a smartphone app. A large dustbin means it needs emptying less often.
