Silent Gliss vs SwitchBot: Which Works Out Cheaper Over Time?

Two very different ways to motorise your curtains

If you want your curtains to open and close on their own, there are two routes that come up again and again, and they sit at opposite ends of the market. One is the SwitchBot Curtain, a small battery robot that clips onto the track or pole you already have and pulls the curtain along for you. The other is a proper motorised track like the Silent Gliss Autoglide 5100, which replaces your track entirely with a motor built into the rail.

This is an honest comparison. We sell Silent Gliss and have done since 1986, and we do not sell SwitchBot, so we are biased and you should factor that in. But the SwitchBot Curtain is a genuinely clever little product and it suits a lot of people, so we are going to give it the credit it deserves and then be straight about where it stops making sense, especially once you look at the cost over a few years rather than just the price on day one.

What the SwitchBot Curtain offers

The SwitchBot Curtain is a retrofit gadget. You clip it onto your existing curtain track or pole, it grips the curtain, and a little motor drives it open and closed. There is no drilling, no wiring and no installer. Most people have it working in a few minutes, and if you move house or change your mind you just unclip it and take it with you. For a renter, or for someone who wants to try automated curtains without committing to anything, that is a real advantage.

It runs on a built-in rechargeable battery, so there is no cable trailing down your wall. On its own it works over Bluetooth from your phone when you are in the room. Add the SwitchBot hub and you also get voice control through Alexa or Google Home, timers, and the ability to open or close the curtains when you are away from home. It is a proper little smart-home product and the app is well made.

At the time of writing a single Curtain robot costs around £90. That is the headline number that makes it look cheap, and for one curtain on a light, free-running pole it is cheap.

What it actually costs once you live with it

This is where the day-one price and the real cost start to drift apart.

Most curtains open from the middle and draw to both sides, and each robot only drives one curtain panel, so a normal pair that meets in the middle needs two robots, which is around £180 rather than £90. If you want voice control or you want the curtains to work while you are out, you also need the hub, which is roughly another £30 to £80 depending on which one you choose. The battery needs recharging every few months, which is a small chore but a chore all the same, so a lot of people end up buying the add-on solar panel at around £25 to keep it topped up. By the time you have a pair of robots, a hub and a solar panel, the "£90 gadget" is closer to £250, and you still have your old track doing the actual work.

That last point matters more than people expect. The robot does not replace your track, it just drives the curtain along whatever track or pole you already have, so it is only ever as good as that track. If your existing track is old, stiff or a bit sticky, the robot has to fight it, the curtains can stutter, and the battery drains far faster than the claimed life. Heavy or interlined curtains make this worse, because the little motor is designed for lighter, free-running curtains, not theatre-weight fabric. And it is a visible plastic unit sitting at the top of your curtain, which is fine in a home office and less ideal in a front room you have spent money on.

Then there is lifespan. The SwitchBot Curtain is consumer electronics with a rechargeable battery, and like anything in that category the battery degrades and the unit has a finite life before you are replacing it. A motorised track is a piece of engineered hardware built to keep running for many years. Cheap things you replace, and the replacement cost is part of the real price even though it never shows up on the first receipt.

How the Silent Gliss Autoglide 5100 compares

The Silent Gliss Autoglide 5100 takes the opposite approach. Instead of bolting a robot onto your old track, it replaces the track with a made-to-measure rail that has the motor built in. The motor lives inside the rail, so there is no gadget on show, the curtains glide silently at around 35 to 38 dBA, and a single track handles a full pair of curtains drawing from the middle without needing two of anything.

It is mains powered through a standard UK plug, so there is no battery to recharge and nothing to keep topped up. It is made to measure up to 6 metres and handles up to 30kg of curtain weight on a straight track, which covers normal lined and interlined domestic curtains comfortably, the kind of weight a clip-on robot would struggle with. Prices start from £483 for the 5100 B, which includes a wireless wall button, and you buy it directly from us, configured to your exact measurements and delivered to your door.

Fitting it is a DIY job. The track comes with the brackets, fixings and step-by-step instructions, and if you can use a drill and a spirit level you can have it up in under an hour. If you want it to run on a timer, the 5100 T opens and closes at set times on its own, and the 5100 TC adds a remote as well, all built into the product with no separate hub to buy. For basic voice control you can put a smart plug on the mains connection and use Alexa or Google Home without any extra kit.

We should be fair about where it costs more. The 5100 is a bigger outlay on day one and it is a permanent fixture, so it is not the right answer if you are renting or you just want to experiment. It replaces your track rather than working with it, which is more commitment than clipping on a robot. For the right person that permanence is exactly the point, and for the wrong person it is overkill, which is what the rest of this comes down to.

Side-by-side comparison

	SwitchBot Curtain	Silent Gliss Autoglide 5100
What it is	Battery robot that clips onto your existing track	Made-to-measure motorised track that replaces your existing one
Fitting	Clips on in minutes, no tools	DIY install, around an hour with a drill
Power	Rechargeable battery (recharge every few months, or add solar)	Mains via UK plug, nothing to recharge
A normal pair of curtains needs	Two robots (one per side)	One track
Curtain weight	Best with lighter, free-running curtains	Up to 30kg straight (lined and interlined fine)
Noise	Audible motor on the curtain	~35-38 dBA, runs quietly inside the rail
Look	Visible unit at the top of the curtain	Motor hidden inside the track, built-in look
Timer / remote	Via app, hub needed for away-from-home and voice	Built in (T = timer, TC = timer and remote), no hub
Starting price	Around £90 per robot (about £250 for a pair with hub and solar)	From £483 (track with wireless wall button)
Lifespan	Consumer gadget, battery degrades over time	Engineered track built to last years
If you move	Unclip and take it with you	Stays with the window

So which one works out cheaper over time?

If you only look at the first receipt, the SwitchBot wins easily, and nothing here changes that. The question is what happens over the next few years.

The SwitchBot route starts cheap but the real cost climbs once you add the second robot, the hub and the solar panel, and it keeps a slow tail of cost through batteries that fade and a unit you will eventually replace, all while leaning on whatever track you already own. The Silent Gliss route costs more up front and then stops costing, because there is no battery, no hub, no second unit and nothing to replace, just a track that keeps doing its job. So the honest answer is that SwitchBot is cheaper to try and cheaper for a year or two, and a proper motorised track tends to come out cheaper the longer you keep it and the more you care about it looking and sounding built-in.

Which one makes sense for you?

The SwitchBot Curtain makes sense if you are renting, you do not want to drill or replace anything, your curtains are light and your existing track already runs smoothly, and you want to dip a toe into automated curtains for as little money as possible. For that person it is a great little buy and we would not pretend otherwise.

The Silent Gliss Autoglide 5100 makes sense if this is your home and you want it done properly, you want the motor hidden and the curtains silent, you have normal-weight or heavier curtains, and you would rather pay once for something that lasts than keep topping up a gadget. Most of our customers fall into that second group, which is why they come to us in the first place.

If you are weighing it up and you are not sure which way to go, you can browse our full electric curtain track range or get in touch and we will give you straight advice with no obligation. We have been doing this since 1986, so we have seen where the cheap option works fine and where it ends up costing more than doing it once.
