What customers say

My backyard looks like new today; We are doing barbecue much more often now.

Mark, Sunnyvale

They came out within 24 hrs (in the pouring rain) to give a quote. They showed up on time, worked promptly, and the results speak for themselves. It was everything you expect but seldom get in service.

Todd Wilms, Menlo Park

Amazing! Very conscientious, punctual and left everything sparkling!

Lisa, Episcopal Church of the Epiphany

Ivan and his crew at Slon are tremendous. We are now using their services at all of our businesses. A+++!

Kevin Goswamy, Applewood Investments

The best part, there are no chemicals used and no wastewater going into your neighborhood creek.

George, Cupertino

Questions and answers

How is this different from just washing it myself?
We don't just spray all the dirt off into the corners, we take it all with us. Our tech is much more effective than any ordinary pressure washing.
How does it work?
We're using hot water (230°F) under high pressure (3500 PSI) with a vacuum reclaim system. Using this, our crew achieves amazing results along with complying to local environmental standards.
How long does the process take?
We'll clean within two hours as long as there is nothing limiting us on-site.
How should I prepare before the cleaning?
There shouldn’t be any cars on the driveway or anything that would interfere with our cleaning.
Do I have to be there?
It’s up to you - but we definitely encourage you to come enjoy the cool tech and cleaning process.
What if it rains?
Is there a hurricane warning in the news? If not, we're in business.
Do I need to provide a source of water?
We bring our own clean water and collect all wastewater, but it would be great if we could also fill up on clean water at your location.
Am I allowed to take photos/videos?
Absolutely! We encourage it.
