We recommend buying instead of renting. A pressure washer makes quick work of all your big and small cleaning projects around the home, farm, business or job site. They use less water than a garden hose for cleaning and because they use a nozzle with a tiny orifice it generates at least 1,500 PSI to blast away mildew, grime, dirt, grease and whatever else you point it at (it works great cleaning the underside of a lawn mower). You can rent them from Home Depot and Lowe’s and local tool shops (for around $80 a day or $300 a week). So if you are only planning to do a seasonal clean of the driveway and back patio then you should probably just rent one. However, after the rental day you will start finding other jobs and end up wishing you had just bought one. In terms of prices there are two classes of pressure washer:
Residential (less than 5 – 10 hours use per week): The small electrics are around $100 – $200 and the bigger gas powered are $300 – $500 Professional (daily use no problem): Electrics anywhere from $500 to $2,000 and gas from $700 – $5,000
