When choosing a folding-arm awning there is a decision as important as fabric and colour but discussed far less: how will the awning open? With a hand-turned crank, or at the press of a remote? At first glance that looks like a comfort preference; in fact it determines many things, from the width limit to sensor use, from daily habit to fabric life. In this article we compare the two options technically.
A manual folding-arm awning works with a crank handle or strap mechanism. When you turn the crank the roller rotates, the fabric unrolls and the folding arms extend forward under spring pressure, holding the fabric taut. To close it you turn the crank the other way. The mechanism is plain; it needs no electricity, motor or cable. Fewer components mean less chance of a fault.
A motorised folding-arm awning works with a tube motor placed inside the roller. The motor is invisible and not noticeable from outside. It is operated by remote control, wall button or mobile app. It requires an electrical connection and supply line, so the electrical infrastructure must be planned before installation.
The first criterion when deciding is frequency of use. On a holiday home where the awning opens a few times a season, the manual model is more than sufficient; the cost of a motor and electrical infrastructure would be an unnecessary burden. On a home terrace used daily, or a café awning opened at every service, turning a crank by hand quickly becomes a tiring routine.
The second and more decisive criterion is width. As the awning gets wider, the weight of the fabric and the spring pressure in the arms increase, and so does the force needed to turn the crank. At narrow sizes manual operation is comfortable, but on wide awnings every opening and closing becomes serious physical work. Above a certain width, manual operation stops being practical; we state that limit during the survey based on your dimensions.
Accessibility is a heading often skipped but important. Turning a crank requires shoulder and arm strength. For older users, people with restricted mobility, or venue staff who must open and close the awning often, that is a real difficulty. The motorised model does the same job at the touch of a button. The user profile can be as decisive as the technical criteria.
Sensor compatibility is the most critical difference between the two models and often decides the matter on its own. Wind, rain and sun sensors work only on motorised systems; a sensor cannot be used on a manual awning. That is because the motor must engage for the system to respond automatically to the condition the sensor detects. On a manual awning only you can provide that response; if you are not at home, you cannot.
This has a direct consequence for awning safety. An awning is a system with a flexible surface and must be retracted above a certain wind speed; otherwise the fabric and arms are strained. Wind often strengthens suddenly. On a motorised awning the wind sensor retracts the system automatically; on a manual one you must either be at home to intervene or accept the damage. We therefore recommend the motorised model on wind-exposed façades.
Fabric life is also indirectly affected by this difference. Fabric retracted while wet sets the ground for mildew and staining. On a motorised system the rain sensor closes the awning in time and it is easy to open and dry it after rain. On a manual system, especially on an awning not used often, the fabric can stay wet for long periods. This is one of the most common reasons fabric life is shortened.
The electrical requirement is the motorised model's only real drawback. A supply line must be run to the point where the awning sits. If an existing building has no such line, cable routing and plastering work come into play; if visible trunking on the façade is unwanted, labour increases. We therefore recommend deciding on a motorised awning before installation; adding later usually means visible cabling.
Power cuts should be considered too. Most quality tube motors have a manual override; with a crank handle you can retract the system by hand. That feature matters especially for closing an extended awning before a storm. When buying a motorised model we suggest confirming this mechanism is present; we show its location and use at handover.
In terms of maintenance load the two systems are close. In both, fabric cleaning and checking arms and joints are done the same way. On a manual system the crank mechanism and gearbox are checked additionally. On a motorised system the operation of the motor and sensors is reviewed. The motorised model has more components, but with regular maintenance that does not create a clear disadvantage.
The cost difference is real and comes from two items: the motor itself and the electrical infrastructure. If a sensor is added, the gap widens further. Whether that difference is meaningful depends on the criteria above. On a narrow awning opened a few times a season, a motor is an investment that goes unused. On a wide, daily-used, wind-exposed awning, the motor and sensor pay for themselves by preserving the fabric's life.
It is also worth assessing this alongside the cassette model. In a cassette awning the fabric is protected when closed; combined with a motor and sensor, the system both retracts itself and protects the fabric inside the cassette. A manual cassette combination is possible but cannot benefit from the sensor advantage. We covered the difference between the two systems in detail in our cassette awning comparison.
In summary: a manual folding-arm awning is plain, economical and more than sufficient for low use, narrow sizes and sheltered positions. The motorised model is necessary at large sizes, in daily use, on wind-exposed façades and wherever a sensor will be used. The deciding question is this: will you protect the awning, or does the system need to protect itself? You can review our awning systems and we can determine the right model together.

Frequently Asked Questions
No. A motor is needed for the system to respond automatically to the condition the sensor detects. On a manual awning only you can intervene; if you are not at home, you cannot.
There is no single figure; the limit depends on fabric weight and arm spring pressure. As width grows, turning the crank becomes physical work; we state the limit during the survey based on your dimensions.
Most quality tube motors have a manual override with a crank handle. We suggest confirming this mechanism is present when buying.
