Surface Cleaners for Sale in Milwaukee, WI

Who has time to scrub filthy floors with a brush? Save time and your back by using a flat surface cleaner pressure washer from Power Wash Store Milwaukee. We have a great selection of flat surface cleaners that will get the job done better and faster than scrubbing or using a regular power washer with a hand-held wand.

If you have heavily soiled cement, a flat surface pressure washer is the only way to go. With a regular power washer setup—hose, gun, wand, nozzle—you have to make sure you maintain the same distance from the nozzle to what you’re spraying for the entire length of the surface. If you’ve ever tried doing this on a big job, you know how darn near impossible this is. A flat surface cleaner maintains a consistent width and virtually eliminates the back pain you get from trying to hold the wand just so for extended periods of time. Heavily stained concrete comes out looking bright and clean.

What is a Flat Surface Cleaner?

A flat surface cleaner is a pressure-washing attachment that spins two or three tips around a spindle close to the ground. Surface cleaners enable faster, better, and less back-breaking cleaning of flat surfaces, such as concrete. Surface cleaners also have a skirt to prevent overspray to keep you relatively dry, especially compared to using a hand wand.

Flat Surface Cleaners vs Standard Wand

Flat surface cleaners are much faster than standard wand pressure washing. Many factors affect exactly how much faster it is. Generally, flat surface cleaners take only about ¼ of the time a standard wand takes. Imagine getting a job done in 30 mins that could take 2 hours with a wand.

Standard wand pressure washers often leave stripes, which look unprofessional and unappealing. Surface cleaners don’t leave stripes when used properly and clean very uniformly.

What Surface Cleaner and Tips Do I Need?

Flat surface cleaners come in a number of different sizes, measured in width and number of tips. We carry 19” all the way up to 48”.

How to measure what cleaner you need. A general rule to get the size surface cleaner you need is to take the GPM of your pressure washer and multiply that by 4 to get the maximum width. For example, 6 GPM x 4 = 24” maximum width surface cleaner.

What nozzle tips you should use? Some surface cleaners have two nozzles, some have up to 4 nozzles. Nozzle sizes are measured in two main ways, fan pattern and GPM flow. For example, a 25035 means a 25-degree fan pattern and 3.5 GPM flow. To figure out your nozzle size, take the GPM of your pressure washer and divide it by the number of nozzles. If your machine is hovering up off the surface, test out larger tips, one half-step at a time. For example, a 6 GPM pressure washer attached to a 2 nozzle machine should use 2503 tips, and if it is floating, try a 25035 tip, test, then 2504, test, etc until the cleaner moves easily and doesn't want to float up off the surface.
