2026 verdict
Curtains that already hang and a budget that matters: the SwitchBot Curtain 3 wins this comparison over the Yoolax Motorized Roller Shade on price, retrofit fit and battery life.
It clips onto an existing rod or rail with no tools, pulls up to 15 kg of fabric, runs below 25 dB in silent mode and is rated about eight months per charge, with Home Assistant able to drive it over Bluetooth without a SwitchBot hub. The Yoolax Motorized Roller Shade is a made-to-measure blackout roller with a thermal insulated backing, a remote that handles up to 16 shades and a three-year warranty, ordered with a Bluetooth, Zigbee or Matter over Thread motor. The Yoolax is the one that darkens a room and reaches every platform; the Curtain 3 is the one that keeps the curtain you already own. Pick the SwitchBot Curtain 3 to motorize existing curtains, and the Yoolax Motorized Roller Shade for a custom blackout covering.

What the differences mean
Retrofit or replacement
The SwitchBot Curtain 3 clips onto an existing rod or rail with no tools and no drilling, keeping the curtain you already own. The Yoolax Motorized Roller Shade is a made-to-measure replacement, cut to the submitted window size and installed with tools, with no retrofit kit.
What it moves
The SwitchBot Curtain 3 walks along the rail dragging the fabric, with position control and Touch and Go manual operation. The Yoolax Motorized Roller Shade raises and lowers a single roller panel on its own tube, which is a window covering in its own right.
Light and heat
The Yoolax Motorized Roller Shade is blackout with a thermal insulated backing, so it darkens the room and slows heat through the glass. The SwitchBot Curtain 3 leaves the light control to whatever fabric is already hanging, which may or may not block the sun.
Battery life
The SwitchBot Curtain 3 is rated about eight months per charge and the Yoolax Motorized Roller Shade about six. Both sell a solar panel separately, so neither is tied to frequent charging, but the Curtain 3 goes longer between them.
Warranty
The Yoolax Motorized Roller Shade carries a three-year warranty against one year on the SwitchBot Curtain 3, the longer cover sitting on the more expensive product.
Connectivity
The SwitchBot Curtain 3 is Bluetooth on its own, with a SwitchBot hub needed for Matter, voice assistants and sunrise triggers. The Yoolax Motorized Roller Shade is ordered with the radio you want, so a Matter over Thread motor reaches Apple Home, SmartThings and Home Assistant without a SwitchBot hub.
Which one to buy if
- you want to motorize curtains you already own
The SwitchBot Curtain 3 clips onto the existing rod or rail with no tools and keeps the fabric.

- you want the widest platform choice without a SwitchBot hub
The Yoolax Motorized Roller Shade can be ordered with a Matter over Thread motor that reaches every major platform.
- you want the lower price and the longer battery
The SwitchBot Curtain 3 costs less and goes about eight months per charge against six.

What owners say
SwitchBot Curtain 3 owners describe the install as the easy part, with adapters for different rails and rods and an app walkthrough that gets it moving without modifying anything. They like the build quality and how quietly it draws up to 15 kg of curtain, and the common pattern is a first unit becoming a second and a third for other rooms. Sunrise opening is the feature they call out as the reason they bought it, and the optional solar panel removes the recharge for high windows. Their warnings are that heavy lined drapes or a bent rail make it stick and need recalibration, and that voice control and sunrise triggers wait on a separately sold hub.
Frequently Asked Questions
Which is better overall: SwitchBot Curtain 3 or Yoolax Motorized Roller Shade?
The SwitchBot Curtain 3 wins on price, retrofit fit, battery life and its Bluetooth Home Assistant path. The Yoolax Motorized Roller Shade answers with blackout fabric, thermal insulation, a wider choice of radios and a three-year warranty, which is what matters if you want a new covering rather than a motorized existing one.
What is the biggest difference between the SwitchBot Curtain 3 and the Yoolax Motorized Roller Shade?

Do I need a hub for either covering?
The SwitchBot Curtain 3 is Bluetooth on its own and needs a SwitchBot hub for Matter, voice assistants and sunrise triggers. The Yoolax Motorized Roller Shade depends on the motor ordered: Bluetooth needs no hub, Zigbee needs a Zigbee hub, and Matter over Thread needs a Thread border router.
