As of August 2015, Northern Tool sells nine brands of pressure washers including models from NorthStar, Powerhorse and General Pump. Models range in price from under $400 to over $3,500. The largest number of models they offer is from the NorthStar brand.
In addition to hot water or cold water pressure washers that operate with electric or gas, Northern Tool sells a variety of pressure washer accessories including nozzles, hoses and pumps. To help consumers determine which pressure washer is best for them, the site publishes an online buyer's guide that educates consumers on how differences in horsepower, pounds per square inch and gallons per minute affect cleaning performance.
