If, you are going to use it on a regular basis, don't rent. Instead, purchase one. Wait until they are on sale. Also check out Harbor Freight
it depends on what you want to use it on. light dirt, an electric is fine. heavy stains or a large are like a driveway, you'll want a more powerful one.
Anywhere from 30 to 70 dollars for 4 hours depending on electric or gas and the psi they offer different rates for longer periods of time check out homedepot.com and type power washer rental even tell if your local store has them to rent
I found it is cheaper to buy a ryobi electric than to rent i bought 1 and have had it 2 years no problem and it was less than $100 and did a great job
