PowerBoss Gas Pressure Washer 3100 PSI Review

Pressure washers are extremely handy tools. Having one makes quick and easy work of vehicle washing and outdoor cleaning, making your neighbors stare at your squeaky-clean car and driveway in awe. Once you use a pressure washer, you’ll wonder how you ever survived living like a caveman by carrying/dragging around a long garden hose that provides hardly any power to clean the inside of your car’s wheel flaps.

PowerBoss Gas Pressure Washer 3100 PSI Review

PowerBoss is one of the world’s leading brands in manufacturing and distributing industrial cleaning machines. They have a diverse line of pressure washers which cater to all sorts of users, ranging from home users who just need to clean their cars and patios to industry users who need to keep their factory floors free of contaminants.

One of their best-selling pressure washers, the PowerBoss 3100 PSI Gas-Powered Pressure Washer, is an excellent choice for medium-duty purposes at home. Let’s see what exactly makes this PWMA-certified (Pressure Washer Manufacturers’ Association) PowerBoss pressure washer such a high-selling unit.

PowerBoss Gas Pressure Washer 3100 PSI

Honda GC190 Engine

This PowerBoss pressure washer utilizes a durable Honda engine which creates the pressure to clean stubborn stains off of your patio and driveway. The engine provides shooting-power which uses up to 2.7 GPM (gallons-per-minute) delivering a force of 3,100 PSI (pounds-per-square-inch).

If you’re familiar with the industry standards, you’ll realize that although this power washer doesn’t support the most powerful of engines out there, it offers enough power for home use and even medium-duty power washing for commercial use.

Like with any engine, this machine needs regular oil changes in order to keep the machine running at an optimal level. One common complaint among users is the engine’s inability to retain oil, frequently finding oil in the air filter and on their garage floors.

In some cases, the oil leaks were trivial and required a quick wipe-down, but several other customers found that even the gasoline tank would leak fuel after minimal usage. Honda is notorious for making great-performing engines, but leakage is common among their engine models, unfortunately, including the GC190.

4 Quick-Connect Nozzles

This PowerBoss gas-powered pressure washer features a system of four quick-connect nozzles (0°, 15°, 40°, and soap nozzles) which offer different spray power and range. The operator simply needs to connect the steel spray wand (included) to the quick-connect nozzles to get to work.

The red 0° cutting nozzle shoots a concentrated stream of water at stubborn stains. The yellow 15° chiseling nozzle is powerful enough to strip paint and lift grime and grease from hard surfaces. The white 40° nozzle blasts water in a wide area which makes quick work when washing large spaces. The soap nozzle, of course, takes soap from the built-in 1-gallon detergent tank to provide much-needed suds when washing your car.

In terms of performance, there’s nothing to complain about; all four quick-connect nozzles work excellently and no strength is sacrificed no matter how wide the spray area. The soap nozzle might hiccup every now and then, but it’s not a deal breaker for almost all users and first-time buyers.

PowerBoss Gas Pressure Washer: Bottom Line

Apparently, the PowerBoss Gas Pressure Washer is only somewhat “OK” compared to other gasoline-powered pressure washers on the market.

Sure, the engine provides 3,100 PSI and up to 2.7 GPM of water blasting power, and the four quick-nozzles indeed provide strong, accurate cleaning ability, but that’s basically all it has going for it.

Although this machine is certified by PWMA, that only means that it can provide the strength that PowerBoss advertises, and it has nothing to do with engine build and other factors that customers consider important. If you can handle a little of oil leaking, this might be the pressure washer for you. Otherwise, keep shopping around.
