The real disadvantages of motorised blinds are cost, a second thing that can fail, and dependence on charge. A motorised roller blind runs about R2,500 to R6,000 per blind supplied and installed against roughly R450 to R900 per square metre for the manual equivalent — often three to four times the price for the same fabric on the same window. Everything below is the honest list; we fit these every week and would rather you spent the money where it earns its keep.
1. The Cost Premium Is Real
Motorising is priced per blind, not per square metre, so it is proportionally most expensive on small windows. On a narrow bathroom or landing window the motor can cost more than the blind itself. Retrofitting a motor to blinds you already own adds R1,800 to R3,500 each, which is why whole-house motorisation is rarely the sensible first purchase.
2. A Motor Is One More Failure Point
A manual roller blind has a clutch and a chain. A motorised one has a motor, a battery, a remote and sometimes a hub — four more components, each of which can fail or lose pairing. In practice the order of failure is battery flat, then handset pairing lost, then the motor itself. Motors are replaceable, but a replacement is a call-out rather than a part you swap yourself, and out-of-warranty motors are not cheap.
3. Batteries Need Recharging
A rechargeable lithium motor holds about three to six months of daily use before it needs charging. That is not onerous, but it is a recurring chore, and on a high stairwell window — exactly the window motorisation suits best — recharging may mean getting a ladder out. Solar-assisted motors largely solve this on a sunny aspect and do almost nothing on a south-facing one.
4. Wired Motors Mean Cabling — and Load-Shedding
A 240V motor needs a cable brought to each window, which is straightforward during a build or renovation and disruptive afterwards. It also stops during load-shedding, unlike battery and solar motors, which store their own charge. If mains wiring is the plan, the cabling decision has to be made before the walls close.
5. Not Every Blind Retrofits
Retrofit depends on the tube diameter and headrail profile of the existing blind. Some mechanisms take a motor cleanly, others cannot be adapted and need a new blind. This has to be assessed on the actual blind — it cannot be answered from a photograph of the room.
Where They Are Still Worth It
None of this argues against motorisation where it solves a real problem: windows you cannot safely reach, wide living-room spans that are heavy to lift by hand, homes with young children where hanging cords are a hazard, and rooms where grouping blinds on a timer genuinely cuts afternoon heat. On those windows the premium buys something. On an easily reachable bedroom window it mostly does not.
