To dive right in, the first thing you might notice about a brush is the material used for the bristles. In most cases, the choice is between two materials, nylon and boar’s hair. Nylon is a synthetic material and is very common, and, therefore, has many options to choose from in regards to size, trim, and jets, but we’ll get there. Boar’s hair, on the other hand, is literally the hair from a boar. I’m sure you didn’t see that coming, huh? The great thing about a boars hair brush is the bristles themselves. Unlike nylon, a man made material, the hair of a boar has multiple tiny bristles on each bristle. This, in turn, is equivalent to a ton of scrubbing surfaces, meaning the brush itself has serious scrubbing power, both on the bottom of the brush, as well as the sides of the brush. Nylon is smooth on the sides and does not offer that extra scrubbing surface but will last significantly longer than a boars hair brush because boars hair is biodegradable. And, it’s still a great scrubbing brush, to be fair.
There are two different size brushes that we sell, the 12-inch and the 16-inch, the 16-inch brush only being an option for nylon brushes. There are other options out there on the market but the principle remains the same for all of them, regardless of specific size. The larger brush, in our case the 16-inch brush, is great for cleaning a larger surface area because, as I’m sure you could guess, the brush has a bigger surface area. The tradeoff for a larger brush is that whatever kind of pressure you’re applying to the brush has to spread over that same large surface area. The water from the jets has a large surface area to spread out over also. The smaller brushes, in our case the 12-inch brush, concentrate that pressure and water into a smaller surface area. So, the smaller the brush, the better the scrubbing power. The larger the brush, the faster you can clean.
The shape of a WaterFed® brush can vary also. The most common brush shape is a rectangle. This shape is less expensive and has more options for jet styles and trim. A radial brush is somewhat of a specialty brush. The radial shaped brushes are a great way to scrub up and under the eves and even the bottom of the window sills. It is not necessary for every job, but can be a helpful resource to have on hand when your windows (and the surrounding area) call for it.
There are two different types of jets, pencil and fan. The pencil jet is a straight stream onto the windows and is most helpful in scrubbing situations. This kind of jet consolidates the water stream into a straight shot onto the window and therefore the window actually gets more wet because of the pencil jet. This is why scrubbing is great with a pencil brush, because all that pure water goes directly onto the window and helps absorb the dirt and grime. The fan brush itself has a wider arch spray, which can give you a quicker rinse. The spray that is created by the fan brush reaches a larger surface area, making this jet a great resource for a quicker clean, and optimal for widows that don’t need to much cleaning help. So long as the window doesn’t require dons of cleaning, fan jets are preferable because of how much quicker they allow you to complete your rinse.
Another brush characteristic to consider when choosing your perfect WaterFed® brush is the style of trim you’d like. Most boar’s hair brushes and some nylon brushes are single trim. This just means the bottom of the brush is a straight shot, a bowl-cut haircut if you will. Boar’s hair brushes work great with this style of trim because when pressure is applied to the brush, all the bristles move together. Because of the multi-surface scrubbing area a boar’s hair brush offers, the bristles are actually working together to scrub anywhere a bristle touches the window surface. The other trim option is to get a brush that has double trim. This option is only offered in nylon material brushes, but could be said to “make up” for the brushes lack of multi-scrubbing surfaces. Double trim just means the brush materials are in two layers. The outer edges are longer than the middle. When pressure is applied to the brush, these outer bristles spread out and help keep the brush from sliding all around and giving you more control (even if your forty feet down below). The inner bristles are the scrubbers.
The last thing to consider when you are ready to purchase a WaterFed® brush is the style of threading you want or need. There are two types of threading, acme and euro. Acme is the threading usually used for inside window cleaning. Euro threading is the most common style of threading for WaterFed® brushes and poles. Each pole has a specific type of threading that is important to match up with your brush. Adaptors are available if your pole is one threading and your brush is another, so don’t panic. The other thing to consider is that some companies make poles and brushes with proprietary threading, meaning the threading will have a special little characteristic that won’t allow it to fit with acme or euro. This can be tricky and limit your brush choices to only those same-branded brushes. Threading is a very commonly overlooked characteristic, but can mean the difference between having many brush options and not.
