TL;DR
SwitchBot says its Curtain Track 4 retrofit motor can run for up to 12 months on a charge, using a 6,400mAh battery setup in the Battery+ version. The motor is listed for sale from Nov. 11, 2026, starting at US$109.99, and requires a compatible SwitchBot hub for Matter and Apple Home integration.

The product is scheduled to be available from Nov. 11, 2026, at prices starting at US$109.99; its Matter and Apple Home integration requires a compatible SwitchBot hub.

The Curtain Track 4 is designed to attach to an existing curtain track without replacing it or making permanent modifications. SwitchBot says the motor has a slimmer body that needs 20 millimeters of wall clearance. For dual-track setups, the company specifies at least 40 millimeters between tracks. The device is rated to move curtains weighing up to 12 kilograms, but that rating does not confirm that every track or curtain arrangement will work. Track shape, tight bends, joints and obstructions may affect compatibility.
SwitchBot says installation can take as little as 30 seconds, and the motor does not require positioning magnets. The design also adds self-lubricating rollers, which are intended to reduce friction and vibration while the unit moves along the track. The company has not provided independent performance testing in the announcement, so the installation time and noise benefits should be treated as manufacturer claims rather than guaranteed results for every home.
Two configurations are offered: Battery+ and Solar. Battery+ combines an internal battery with a removable module for a stated total capacity of 6,400mAh. The module can be taken off and charged without removing the motor from the track. SwitchBot’s “up to 12 months” estimate is not a universal runtime guarantee: battery life will vary with curtain weight, travel distance, how often the curtains move and other operating conditions. The Solar version includes a panel intended to reduce manual charging, though the amount of sunlight reaching the panel will affect its usefulness.
Other controls include the SwitchBot app, scheduled opening and closing, an optional remote and Touch&Go, which starts movement when a user gently pulls the curtain. QuietDrift moves the curtains at 0.5 centimeters per second to reduce operating noise. At that speed, a two-meter movement would take about six minutes and 40 seconds, making the mode a slower alternative to standard operation.
Curtain Track 4 automates existing rails with a claimed year between charges
SwitchBot’s retrofit motor adds scheduled and app control to compatible U-rail curtains. Battery life, track fit and smart-home features depend on your setup.
What the retrofit changes
The motor attaches to an existing compatible track, so replacing the rail is not required.
Removable charging module
Charge the battery module without taking the motor off the track.
Panel-assisted charging
Sunlight can reduce manual charging; shaded windows may still need it.
More ways to move curtains
Use schedules, the app, an optional remote or Touch&Go pull activation.
Check the track before buying
Weight capacity alone does not confirm that a particular rail and curtain setup will fit.
The motor needs 20 millimeters of wall clearance; dual tracks need at least 40 millimeters between them.
Bends, joints and obstructions can affect compatibility.
The stated limit is 12 kilograms, but that does not guarantee every lighter setup will work.
Smart-home control needs a hub
The motor does not connect to Matter independently.
| Control option | What to know |
|---|---|
| SwitchBot app | Schedules and device controls |
| Matter and Apple Home | Requires a compatible SwitchBot hub |
| QuietDrift | Moves at 0.5 centimeters per second; a two-meter movement takes about six minutes and 40 seconds |
Battery and Hub Costs Shape the Upgrade
The advertised battery life could reduce how often owners need to reach a curtain motor to recharge it, while the removable Battery+ module avoids taking the motor off its track for charging. That may be useful for high or awkwardly placed windows. The claim is qualified, however: users with heavier curtains or frequent operation may get less time between charges, and the announcement does not specify a standard test schedule behind the 12-month figure.
Smart-home buyers also need to account for the hub requirement. Matter is not built directly into the motor; a compatible SwitchBot hub is needed to connect it with Apple Home and other supported platforms. Buyers who do not already own a suitable hub may face an additional cost, and some device-specific settings may remain accessible only through the SwitchBot app.
The product’s retrofit approach could let users automate curtains while keeping their existing track. That convenience depends on the track meeting the device’s compatibility requirements. The stated weight capacity alone is not enough to determine fit, particularly for tracks with bends or obstructions.

How Track 4 Fits SwitchBot’s Lineup
The Curtain Track 4 is the latest version of SwitchBot’s curtain motor, a product category intended to add powered control to curtains already installed in a home. Rather than replacing the curtain track, the unit travels along a compatible existing rail. The new model’s headline changes are its smaller form, revised battery options, self-lubricating rollers and removal of the magnet-positioning step described for some earlier models.
SwitchBot lists Alexa, Google Assistant, Siri Shortcuts and Samsung SmartThings support when the motor is used with a compatible hub. The same hub acts as a bridge for Matter integration, including Apple Home control. Matter support may allow the curtains to be included in scenes and automations, such as scheduled opening or closing, but the company says the motor itself does not connect to Matter independently.
SwitchBot lists prices starting at US$109.99, CA$139.99, £99.99 and €99.99. Pricing may differ by configuration, and the company says coupons may be available. A hub, remote or other accessory may be an additional purchase depending on the package selected.
““Up to 12 months” of operation on a single charge for the Battery+ configuration.”

Runtime and Track Fit Vary
The announcement does not specify the usage pattern, curtain weight or travel distance used to calculate the up-to-12-month battery estimate. Actual runtime is also likely to depend on how frequently the motor is used. Solar charging performance will vary with sunlight, and shaded installations may still need occasional manual charging.
It is also not yet clear how the motor will perform on individual tracks with tight bends, joints or other obstructions. SwitchBot’s 12-kilogram capacity is a stated load limit, not confirmation that all curtains below that weight are compatible. The announcement does not detail whether every app feature, including QuietDrift and Touch&Go settings, will be available through Matter-connected platforms.
Prices are listed by configuration and region, but final package contents and the cost of any required hub or accessories may vary. Buyers should check the specific listing and track requirements before ordering.

Key Questions
How long does the SwitchBot Curtain Track 4 battery last?
SwitchBot claims the Battery+ version can run for up to 12 months on a charge. The company says actual battery life depends on factors such as curtain weight, travel distance and frequency of use.
Does the Curtain Track 4 work with Matter without a hub?
No. The motor does not have native Matter connectivity. A compatible SwitchBot hub is required to bridge it to Matter and platforms such as Apple Home.
Can the motor fit any curtain track?
No. The Curtain Track 4 is designed for U-rail tracks, and track shape or obstructions may affect compatibility. SwitchBot lists a 12-kilogram curtain limit, but that does not establish that every setup below that weight will work.
What does QuietDrift do?
QuietDrift moves the curtain at 0.5 centimeters per second to reduce operating noise. A two-meter movement would take about six minutes and 40 seconds at that speed.
When does the Curtain Track 4 go on sale?
SwitchBot lists availability from Nov. 11, 2026, through its official online Amazon store. Listed starting prices vary by region and configuration.
