Are Battery Powered Pressure Washers Worth it?

Pressure washers are not only excellent cleaning machines, but they are also more economical with water than a regular garden hose. However, the more popular gas and corded pressure washers can be quite expensive to buy and maintain.

That’s why manufacturers such as Dewalt, and Bosch, among others, came up with the battery-powered pressure washers. Although these cordless pressure washers are relatively new in the market, they have a growing demand. Because of this, other consumers are always wondering if they are worth the fuss.

Like other pressure washer types, these cordless, battery-powered(Li-Ion) pressure washers have both benefits and drawbacks. Battery-powered pressure washers are quieter, have no emissions, lightweight and more portable but have less cleaning power.

This post will shine some light on the pros and cons of battery-powered pressure washers, and it’s up to you to decide if they are worth the expense.

What is a battery-powered pressure washer?

Also called a cordless pressure washer, electrical handheld pressure washers run on one or two rechargeable Lithium-ion batteries with light to medium spraying power. They are lightweight, compact, and do not require an electrical outlet or water source to work.

One 4.0Ah fully-charged battery lasts between 20-40 minutes, depending on the type of task and model. Some modern models can run for 60 minutes before a recharge, which is enough time to complete most light pressure washing tasks.

The spraying power of most models can range from 300 PSI to 1300 PSI. There are also battery-powered pressure washers with tanks, which are in-built water reservoirs. Other models use a bucket as a water source instead of connecting it to a hose, thus allowing you to use it away from your house.

How does a battery-powered pressure washer work?

Even with varying brands and models, battery-powered pressure washers work the same way. They use electric power from a battery to run the machine’s engine. First, the battery supplies power to a pump. This pump then draws in the water and sends it via two suction valves to one piston each. The pistons are on a movable plate(swash plate) moved back and forth by the water pressure. This motion sends the water at high speed through pressure valves to the nozzle, and the water jets out at high pressure. The motor speed will determine the pressure of the water jets.
