How much time will it takes to assemble the product?
Mounting the brushes on the robot can take approx. 10 seconds. The rest of the robot is assembled.

Is crane compulsory for positioning the robot on the PV moldule installation? 
The pvClean does not need any crane. It’s placed manually on the panel.

What is the impact of the robot if used on the partially cracked PV module (surface)?
The robot weighs 30 kg, less than a worker. The cleaning company has to know in advance if the installation is damaged and judge for themselves if they want to clean the installation. For this purpose we recommend the customer to take out an insurance to cover damages during cleaning. We assume no liability whatsoever.

What is the guarantee for this product?
Our robots have 12 months guarantee. We offer the possibility to extend the guarantee against payment. Damages caused by incorrect use or incorrect handling of the robot are not covered by the guarantee.

What is the failure rate, what is the meantime before failure?

Which is the expected lifetime of the robot?
10 years

How far can go the robot from the electrical and water supply ?
The supply hose has a length of 50 m. You can extend another 50 m by buying an additional extension hose.

Which are the robot dimensions?
Under “Specifications” on the website, you find the detailed technical information of the robot.

Which is the maximal allowed inclination for the application of pvClean robot?

The pvCleanrobot moves forwards on the pv-installation (panels) with a maximal inclination of 15°. The application of the robot on installations with higher inclination will cause the fall of the robot.

Is there a product with less weight than the pvClean?
Yes, the pvEco robot.

How far can go the robot from the electrical and water supply?
The supply hose has a length of 50 m. You can extend another 50 m by buying an additional extension hose.

Which are the robot dimensions?
Under “Specifications” on the website, you find the detailed technical information of the robot.

Is the robot safe from falls?
The robot has 24 vacuum-suction cups which allows it to be permanent sucked on the surface during the operation. An additional safety mechanism turns off the equipment immediately in case of an error leaving it stuck to the surface.

Which is the maximal inclination allowed for the application of GS robot ?
The GS robot moves forwards on the pv-installation (panels) with a maximal inclination of 45°, using its vacuum-suction cups.

Which is the price of the GEKKO FACADE robot?
The GEKKO FACADE is a project tailored cleaning solution for one building application. It's not a „plug and play“ cleaning machine, which can be used in different buildings.

There isn’t a general standard price for this solution. The robot is a part of the whole cleaning project solution. Approx. EUR 160'000.- + Project Costs

How many floors high can be cleaned with the GEKKO Facade robot?
Up to approx. 20 floors high building could be cleaned when the facade suites the requirements from the robot and the wind conditions allow the work with this equipment. Max high approx. 20-50 mts and no obstacles higher than 30mm.
For higher buildings, we suggest our GEKKO Gondola or our GEKKO Gondola RETROFIT.

Do you have a portable facade robot to clean more than one building facade?
We’re developing the new GEKKO FACADE MOBILE, which will be able to be used for more than one building. Therefore its application depends very strongly of the building architecture facade. The GEKKO FACADE MOBILE will be able to be applied to simple facades. Building design needs to be analyzed.

Which is the price of the GEKKO FACADE MOBILE?
The GEKKO FACADE MOBILE robot will be launched approx. in September 2021. The approx. price will be around 180‘000 EUR + Project Costs

Which is the maximal inclination allowed for the application of GF and GFM robot?
The GF and GFM robots work vertically on the facade, moving forwards with the vacuum-suction cups. Overhanging is not possible.
