There are two ways to clean indoor car parks. The first method is pressure washing, the second involves the use of special car park sweepers. Which service should you choose?
Cleaning a car park with pressure washers requires several – sometimes even up to four – times as much time compared to car park sweepers. And of course, manpower costs more!
Another important factor to consider is that with pressure washing, the dirty water is channeled into the sewerage system. However, before the wastewater reaches the urban sewerage system, it has to pass through the general utility line, that may contain oil and sand separators and pumps. Higher than normal amounts of mud can result in blockages, the removal of which can prove to be quite laborious.
The most practical way to clean car parks is by using a specific sweeper designed for that purpose. These machines effectively wash the floors and at the same time also collect all the dirt and wastewater in a recovery tank. Even if pressure washers are used for part of the job, the wastewater will be collected in a recovery tank. Thanks to this, you do not have to worry about blockages.
Car park sweepers get the job done relatively quickly. For example, the machine can clean a car park as large as 10,000 m² in just six to eight hours. This means that parking is disrupted for a shorter amount of time, which is good for everyone involved.
