A manual roller blind runs on a chain and a clutch. A motorised one has a tubular motor sitting inside the tube, and the choice usually comes down to how high the window is, how heavy the blind is, and whether you can get power to it.
What a chain and clutch actually do
You pull the chain, the clutch turns the tube, and a brake holds the fabric wherever you stop it. It is simple gear and it lasts for years. On a small or medium blind there is nothing wrong with it at all.
It gets less pleasant as blinds get bigger. A wide blockout on a long drop is a lot of fabric to wind by hand, and you feel it twice a day. High windows over a stairwell or above a kitchen bench are worse again, because you need a pole or a ladder just to reach the chain.
Where the motor actually sits
The motor is a tube inside the tube. It slides into a 38mm or 45mm roller, so a motorised blind looks no bulkier from the room and there is no box hanging off the bracket. The upper and lower limits get set at install, so the blind stops in the same two spots every single time.
That repeatability is the part people underestimate. Four blinds across one wall finish dead level, which a chain never quite manages.
Battery, plug pack or hardwired
- Rechargeable lithium battery motors. Nothing to wire, and you charge them with a lead every six to twelve months depending on how often the blind runs. Easiest option in a house that is already finished.
- Low voltage motors on a plug pack. Quiet in operation, and they need a power point within reach of the head of the blind.
- Hardwired mains motors. Neatest finish, no visible lead anywhere, and the cabling is a licensed electrician job.
A new build or a renovation with the walls still open is the moment to run cable. Retrofitting a hardwired motor into finished plaster is possible, it is just more work than it needs to be.
What you get besides not pulling a chain
Remotes with separate channels, so one button runs a room and another runs the lot. Wall switches that look like a light switch. Timers, so the sunscreens drop before the afternoon sun lands on the west side of the house. Sun and temperature sensors, if you want the blinds working while nobody is home.
Awkward windows are the strongest case. Anything above a stairwell, behind a kitchen sink, over a bath, or in a raked ceiling where the head of the glass is out of reach. A motor turns a blind you avoid using into one you actually use.
The child safety angle
A motorised blind has no chain, so there is no loop anywhere near a cot or a bed. That is often what decides it in a nursery.
Manual blinds are safe too, provided the install is done properly. The Australian rules require a cleat or a tensioner fixed to the wall so a loose chain cannot form a loop of 220mm or more within 1600mm of the floor. We fit those as standard, but they only work if the chain actually gets wound onto the cleat.
Where we would still fit a chain
Small windows. Blinds you barely touch, like a laundry or a spare room. Anywhere with no power nearby and no appetite for charging a battery every so often. A guest bathroom does not need a remote control.
Mixing the two is completely normal. In most houses we do, the big living room spans and the high windows get motors, and the rest of the house runs on chains. That is usually the sensible middle.
A chain is also the simpler thing to live with in a holiday place or a rental, because there is no battery to charge and no handset for the next person to lose.
Things worth asking before you decide
Ask where the charge point or the power point will be, because a lead dangling down a wall is the one regret people mention. Ask how the motor is programmed, so you know you can add a handset later. And ask about the tube, since a motor needs 38mm or more and that can change the bracket projection on a shallow reveal.
We can show you a motor running at the window during the free measure and quote, which beats any description. Have a look at the motorised roller blind options, the wider roller blind range, or get in touch and book a time that suits you.
Common questions
Do motorised roller blinds need power at every window?
Not necessarily. Rechargeable lithium battery motors need no wiring at all, just a charge every six to twelve months depending on use. Low voltage motors need a power point nearby, and hardwired mains motors need cabling run by a licensed electrician.
Are motorised blinds safer around children?
There is no chain, so there is no loop near a cot or a bed, which is why nurseries often get motors. With a manual blind the Australian rules require a cleat or tensioner so a loose chain cannot form a loop of 220mm or more within 1600mm of the floor.
How long does a battery motor run before it needs charging?
Six to twelve months in most rooms, depending on how many times a day the blind runs and how heavy the fabric is. A big blockout on a wide tube draws more than a small sunscreen. Charging takes a few hours with the lead supplied.
