Question 1

can i add casters to the body and what is the cost?

Accepted Answer

For home use you may not need casters but for professional surface cleaners that you will use every day you will run into many situations where casters will come in handy when cleaning things like uneven surfaces such as driveways and sidewalks that have cracked, become uneven, partially tipped, or sunk, or when cleaning pavers that are spaced a bit wide between each other. Wide cracks can cause the surface cleaner to lose it's ability to float  which causes it to drag on the surface rather than hover. The other problem that you will encounter is the brush around the base of many surface cleaners will eventually wear uneven over time as it makes contact with pavement, and when it becomes uneven from wear the surface cleaner will not hover properly. Wheel kits are a great idea in a professional environment. I build my own wooden platform out of 2"x2"s, threaded stock, and 3 good quality swivel wheels. The wooden frame sits above the surface cleaner. One wheel sits out in front of the surface cleaner and the other two sit on each side at the back.  The threaded stock is attached through the wooden frame and through the top of the surface cleaner and is then used to raise/lift it up slightly above the ground surface just enough to keep the brush from dragging on the pavement. Wheels work great for uneven surface cleaning and should be considered if you use it commercially .  After 12 years in business I consider wheels on a surface cleaner a necessity. IMO

Question 2

Is this machine works on roof?

Accepted Answer

If you can get a pressure washer machine, hoses, water, etc. up on the roof, (I assume you are talking a metal roof that is smooth and flat), I see no reason why it would not operate as intended.

Question 3

Is this machine works with waterflow 2.4 gpm???

Accepted Answer

Use the formula 4” of surface cleaner to 1gpm flow. So of you have a 2.5gpm washer your surface cleaner to work properly should be about 10”, or half the size of this one and the nozzles would have to match (flowing 1.75gpm each).
