Do we need a water tap An external water tap is always the best source for obtaining water to run our patio cleaning machinery. If an external water tap is not available, then all of our customised vans are also fitted with 400-litre tanks which enables us to provide 60 minutes of professional patio steam cleaning as well as 20 minutes of high-pressure patio jet washing. We also have a large selection of special adapters to fit most internal water taps. If you think you might have a problem with water the best thing to do is contact our team directly and let us know your circumstances. I'm sure we will be able to work out a way to get your patio clean.
