How Motorised and Cordless Roller Blinds Work

Grenoble Herve Thiery 2019 007 1

Motorised roller blinds have a small motor inside the tube that raises and lowers the blind at the touch of a button, by remote, wall switch, app or voice, so there's no chain to pull. They run on either a rechargeable battery or hardwired mains power, and the right choice mostly comes down to whether there's power at the window.

What "motorised" actually means

Inside a motorised roller blind, a motor housed in the tube does the lifting that a chain would otherwise do. You control it however suits you: a handheld remote, a wall-mounted switch, a wand, or an app on your phone that also works with Alexa and Google Home for voice control and schedules. Cordless means the same thing, no operating chain hanging from the blind, which is part of why people choose it for children's rooms.

Rechargeable vs hardwired

The big advantage of rechargeable is that it avoids needing an electrician or existing power at the window, it just charges via a USB cord plugged into the blind.

 

Hardwired makes sense when wiring can be run during a build or renovation, so you never think about charging.

The honest truth about battery life

How often a rechargeable motor needs charging varies, and it's worth being straight about this, because some competitors advertise "charge once a year" as if it's fixed. It isn't. Charge frequency depends on three things: the size of the blind, the weight of the fabric, and how often you use it. A large blockout blind lifts a lot more weight than a small sheer, so it depletes faster, in practice, top-ups range from roughly once a year to a few times a year.

 

Two more things worth knowing: lithium batteries naturally hold less charge as they age over several years, so an older motor will need charging a little more often, that's normal, not a fault. And leaving a blind on charge overnight, every night, actually shortens battery life rather than helping. Charge it when it needs it, not constantly.

Why people motorise

Child safety: no chain at all means no cord within reach, the main reason people motorise a child's room.

 

Hard-to-reach windows: high windows, stairwell windows and rooms full of blinds become one-touch.

 

Longevity: because no one handles the chain or fabric, there's less wear, so the blind tends to last longer.

 

Convenience: schedules and voice control across a whole room.

The bottom line

A motorised roller blind uses a motor in the tube and a remote, app or voice command instead of a chain. Rechargeable motors avoid needing an electrician and charge by USB; hardwired motors run off mains and suit new builds. Battery life varies with size, fabric weight and use, anywhere from once to a few times a year, so treat "charge once a year" claims with caution.

Frequently Asked Questions

How do cordless roller blinds work?

A motor inside the tube raises and lowers the blind, controlled by a remote, wall switch, app or voice, so there's no chain to pull. The motor runs on either a rechargeable battery or hardwired mains power.

How often do you charge battery roller blinds?

It depends on the blind's size, fabric weight and how often it's used, typically from about once a year to a few times a year. Larger, heavier blinds need charging more often, and batteries hold less charge as they age.

Are motorised blinds better for child safety?

Yes. With no operating chain, there's no cord for a child to reach, which removes the main hazard of a corded blind. It's the most common reason to motorise a nursery or child's room.

Do motorised roller blinds work with smart home systems?

Yes, they work with Alexa and Google Home, so you can use voice control and set open/close schedules.
