Best Pressure Washers Under $100 (2026)

Cleaning power comes from pressure and flow together, and the Greenworks lists both: 1700 PSI at 1.2 GPM. Multiplying them gives about 2,040 cleaning units, a useful way to compare machines that quote different PSI headlines. The listing positions it for light residential cleaning of cars, trucks, patio furniture and similar jobs, which is the honest scope of a washer in this class.

Compared with the Westinghouse ePX3100s, which advertises 2100 max PSI, the Greenworks is more modest, but its flow is stated plainly, while the Westinghouse figure of 1.76 GPM is a maximum reached at the lowest pressure setting. Electric washers quote a max PSI that is a peak rather than a sustained number, so a plain 1700 and 1.2 reads as the more believable pair.

Ownership is simple: no gas, no oil, no spark plugs, no air filter and no pull cord. Drain the pump and hose before freezing weather and avoid running it dry. It is the pick for a household that washes cars and furniture a few times a year. Always test a new spray pattern on a hidden spot first, and keep the tip at least a foot from painted surfaces. Wear closed shoes, because water at this pressure can still bruise a foot. Keep a small bucket of clean water nearby to prime the pump if the flow sputters at startup.

The ePX3100s advertises the largest max PSI in the group at 2100 and ships with a foam cannon and a turbo nozzle. A turbo nozzle spins a 0 degree jet in a cone, which cleans faster than a fixed fan tip but at the expense of reach and control. The foam cannon is the more useful accessory for car washing.

The flow figure of 1.76 GPM is a maximum reached at the lowest pressure setting, so pressure and flow do not peak at the same time. In other words, the machine does not deliver 2100 PSI at 1.76 GPM. Treat it as a light-duty tool with a bigger peak than the Greenworks, not as a step into driveway cleaning.

Store it drained and indoors during cold weather. It is the value pick for a buyer who wants accessories and a higher peak figure. A foam cannon needs a thin soap mix and a wide tip to produce thick foam, so follow the label on the bottle. Rinse from the top down and let the soap sit for a minute before rinsing.

Sun Joe is among the best-known consumer pressure washer brands, and the SPX100-GO is its compact, portable entry. It lists 1800 PSI max, an electric peak figure rather than a sustained rating, and positions itself for all-purpose light cleaning.

The listing gives fewer flow details than the Greenworks, so you cannot calculate cleaning units from it. That is a weakness for comparison, though the brand record on parts and manuals is reassuring.

Keep the inlet screen clean and store it drained. It suits a buyer who values a recognizable name. Because the listing gives little about the pump, expect a basic axial cam design, which is typical for electric consumer machines and not meant to be rebuilt. Use a clean water source and filter if needed.

The 1600 PSI model is the lower sibling of the 1700. It keeps the same 1.2 GPM, giving roughly 1,920 cleaning units against about 2,040, a difference you would struggle to notice on a car.

It shares the no-gas, no-oil design of the Greenworks range. If the price is lower than the 1700 on the day, the saving is worth taking.

Drain it before storage. Compared with the 1700 model, the money you save is small, so choose by what the day's listing price allows. Keep the nozzle in a place you will remember, because loose tips go missing.

The KEEPEAK is a handheld that draws water from a bucket or hose and runs on two 4.0Ah batteries. It is not a pressure washer in the sense of a corded unit with a mains-fed pump, because a battery pump cannot sustain the flow of a plug-in machine.

Its 1450 PSI is a peak claim from the pump, and its flow is low, so cleaning units are far lower than a corded Greenworks. Where it wins is portability: you can wash a boat, a bike or a patio chair far from an outlet.

Keep the batteries indoors and rinse the nozzle. Battery washers are limited by the pump, which cannot sustain the flow of a corded machine. Treat the run time as best-case and carry the second battery on longer jobs.

The OUYESU offers 30 adjustable pressure levels and a brushless motor, and claims 60 to 90 minutes of run time. Fine control is useful when cleaning delicate surfaces.

The 1200 PSI is the lowest peak in the group, and the run time claim depends on level.

Store it indoors. Fine control is an advantage on thin paint and plastic trim, but remember that low pressure also means slow rinsing. Start at a low level and step up only if needed. Treat the claimed minutes as a best case, and keep the second battery on the charger.
