Commercial grade pressure washers are going to be your best option to tackle the toughest cleaning jobs in the shortest amount of time, and are well-suited to stand up to daily use on the job site, whether you’re a contractor or starting a pressure washing business. These dependable pressure washers are going to keep you focused on the job and not finding replacement pressure washer pumps, hoses, etc.

1. Simpson Cleaning 4200 PSI Power Washer

If you’re on the fence of what size pressure washer to buy, just know that you’re getting more than just higher PSI and flow rate (GPM) with these commercial power washers. The Simpson not only has a dependable Honda GX390 engine, but also uses a professional-grade three piston crankshaft pump (aka triplex pump). These are superior to your home-grade washers, and are designed for frequent commercial use with greater efficiency, making it great for a contract or professional cleaning business.

All of the models on this list are fairly similar in reliability, it simply depends on your needs. If you’re looking for the best commercial pressure washer, this Simpson 4200 has a slightly higher pressure and flow rate than the two below, but heads up – it’s also the heaviest!

2. Pressure Pro Heavy Duty Pressure Washer

Pressure Pro is a close second, as it offers almost all of the same key features as the Simpson power washer above, like the Honda engine, but with some important added details. The triplex pump is manufactured by CAT, an extremely reliable brand, and will keep your machine running cooler (and longer) than it’s counterparts. And should it ever begin to heat up, the built-in thermo sensor offers peace of mind.

This model has a considerably higher price tag, but is about 40% lighter than the Simpson, and is the most suited for use and abuse on the job site out of the three on the list. If pressure washing is your business, it’s worth the extra investment for a long-lasting commercial pressure washer.

3. Briggs & Stratton 4000 PSI Pressure Washer

This heavy-duty Briggs Stratton power washer is the cheapest commercial pressure washer on the board, while still maintaining a 4000 PSI and 4 gallons per minute flow. The 420cc engine is larger than the Honda GX390, but that doesn’t mean it’s as reliable.

It’s noticeably more compact than the larger Simpson model (although just as heavy), and offers a detergent injection system for easy cleaning solution integrate (note: read the user’s manual to be sure the detergent you have is suitable for this system). If you’re looking for the best commercial pressure washer for under $1000, look no further.

4. Karcher 4000 PSI Gas Pressure Washer

The Karcher pressure washer promise is “Cleaner. Quicker.” which is what you’ll get with this professional grade power washer. What we like about the Karcher is the combination of a decent price, compact footprint for easier storage, and the Remote Pressure Control – allowing you to change the flow rate on the wand, on demand. Combined with the ergonomic handle, this is a really handy, time-saving feature.

Fair warning, there are a few quality concerns about the shipping and handling of this one, but it looks like they may have addressed their customer service issues within the last couple years.
