Carpet Cleaning Truck

Carpet Cleaning Truck
do i need electricity on in my house to get carpets cleaned?

We rented a house, and are all moved out, and we are just cleaning it out now ..we have until April 1st to have it cleaned…we already turned the water and electricity off…
we need to get the carpet cleaned and i didnt know if the professional carpet cleaners need our electricity or if they have their own pumps and generators in their trucks?
i would hate to have to turn on the electricity again for only one day…
what to do?

the pros have their own stuff going on. they keep the van, truck running cause its the generator. its all self contained, it also provides thehot water.
