The SwitchBot Curtain Track 4 is a small retrofit robot that clips onto existing U-rail tracks and turns regular curtains into smart curtains in as little as 30 seconds. SwitchBot says a new Battery+ version runs for up to 12 months on a single charge, and you remove only the battery module to recharge it while the motor stays in place. The company says it is available from November 11, 2026, through its own store and Amazon.
Curtain Track 4 clips onto U-rail tracks you already own
The device attaches to the rail and moves your curtains open and closed along the track. Curtains can be scheduled to open in the morning or close in the evening, and a feature SwitchBot calls Touch&Go starts the motor with a gentle pull. SwitchBot says the motor moves curtains weighing up to 12 kg.
Battery+ runs up to 12 months and detaches for charging
SwitchBot says the Battery+ version can run for up to 12 months on a single charge, depending on use. It combines a built-in battery with a detachable module for 6,400 mAh of total capacity.
You detach just the battery module when it needs charging, while the main motor stays mounted on the curtain track. A separate Solar version pairs the robot with a solar panel to cut down on manual recharging when there is enough sunlight.
Installation takes as little as 30 seconds
SwitchBot presents the setup as something you can do in as little as 30 seconds, without replacing your curtains or modifying your home. The device goes onto the existing U-rail, and SwitchBot says no positioning magnets are required.
What you need
Curtain Track 4 is designed for compatible U-rail tracks. SwitchBot lists a required wall clearance of 20 mm and dual-track spacing of 40 mm.
Control comes through the SwitchBot app, an optional SwitchBot Remote, or a gentle pull on the curtain. Voice and platform control is a separate step: SwitchBot says a compatible SwitchBot Hub is needed to add Alexa, Google Assistant, Siri Shortcuts, SmartThings, and Matter, and the Hub and Remote are sold separately unless included in the package you pick.
