Ryobi’s system is unique in that it is designed so that two painters can work off it at the same time. It even comes with two rollers to work with. The unit constantly recalculates the paint and stirs it. This allows full thickness paints to be used with it, without any problem with clogging. There are two separate paint flow controls, allowing each user to individually set the ideal paint flow for their work. A reversible pump empties the hose and tool of excess paint when the work is done, making cleanup easier. The kit comes with everything you need, including two rollers a corner pad and a cut-in pad.
Wagner invented the power paint roller, so you'd expect them to rank high in anyone's list. They've come a long way since their first units, which I can clearly remember seeing (and being skeptical about) in the store, back when I was a professional painter.
This unit comes with a variable speed pump, allowing the user to set the paint flow to match their painting speed. It also has an 18-inch extension handle, which is real nice to have. I really like using an extension handle with rollers, because it gives better control, better reach, and lowers operator fatigue. Since this is an internal feed unit, the cores of the roller covers are perforated. The kit comes complete with both 3/8-inch and 3/4-inch nap rollers.
Wagner has developed a reversible feature on the pump, along with a quick clean connector for faster cleanups. Since cleaning one of these units is the worst part of using them, that's a nice option to have.
HomeRight has produced a really nice unit, with some great features. The best things about this unit are the “RapidClean™” paint saver feature, which pumps unused paint back into the can, and a Roller Keeper which stores a wet roller overnight for continued use the following day (although I wouldn’t try leaving it there for two days). The pump is supposed to work with all sizes of paint cans, up to 5 gallon buckets (although they won’t fit on the base). The complete kit comes with a 3/8-inch nap roller cover, painting pad for corners and edges, and a 16-inch extension handle.
The Black & Decker power paint roller is much like the HomeRight one. In fact, they look enough alike to make one wonder if they came out of the same factory. It has a 16-inch extension handle and comes with a 3/8-inch nap roller. The base is fitted to a one gallon paint can, and can be used with either round or square ones. A 20-foot paint hose allows painting a 40 foot work area, without having to move the pump.
Graco EvenFlow In-Line Valve Roller Assembly 245397
What we have here is a power roller assembly that is made to attach to an airless paint sprayer. As such, it will really outperform any of the units I’ve listed, and really should be the number one pick. However, I didn't pick it as number one, because of the several hundred dollar price tag of the airless paint sprayer. This is what a professional painter would use, instead of an all-in-one power paint roller. Even so, I really don’t recommend this type of unit for a homeowner, as you’ll have a little bit of trouble recouping your investment. However, should you decide that you want the best, this is it. Graco makes some of the finest professional paint equipment available. I have owned their equipment and should the need arise, would never hesitate to buy it again. One of the really great things about these, besides the quality construction, is that they come with a much longer extension handle. I find that working with a 3-foot long handle makes rolling faster and less tiring. While you have the extra weight of the handle, you have much less reaching to do.
