Run a hand down the siding under my covered front porch and it comes back gray. It isn't algae or mildew, just dust and dirt blown off an open property and packed onto the two spots rain never reaches, the covered front porch and back patio. It got worse fast this year, after a 30-home development went up a quarter mile away and started excavating and clearing trees. I used to call a service for this. This spring I bought a Ryobi 2,100 PSI corded electric pressure washer for $199 instead, spent an afternoon on it, and haven't called since. It joined the Ryobi tools I consider worth every dollar. What surprised me had nothing to do with performance: the box is missing the one piece you need before you point it at your house.
One quote cost more than the whole machine
A visit averages $311, and mine would need more than one
Angi's 2026 figures put the average house wash at $311, with most homeowners paying between $100 and $711. On an open property, dust never really stops settling, and a covered porch or patio keeps it because the rain that cleans the rest of the house never lands there. A development that won't wrap up this season means one cleanup was never going to cover it. So the real comparison isn't $199 against $311. It's $199 once against $311 a visit, several visits deep.
That arithmetic is unusual for me, because most of my Ryobi purchases start with a battery calculation instead of a tool price. Buy the bare tool, add a pack, add a charger, and the shelf tag turns out to be the smallest number in the transaction. This machine has a cord. The $199 is the entire cost, and the only thing I've added since is detergent. Ryobi backs it with a three-year warranty, and Home Depot takes returns for 90 days.
The cord is what makes a whole house possible
Siding is a marathon job, and marathons drain packs
Every green tool I own gets sorted by whether its motor works in bursts or never gets a break, and a house wash is the second kind. Professionals budget over two hours for siding, none of it stop-and-start. That's the duty cycle that flattens batteries and leaves you waiting on a charger. The cord makes the question disappear. Runtime stops being something you ration.
Assembly ran about 10 minutes, most of it spent reading a manual I didn't need. The handle telescopes, the wheels do the rest, and everything stows on the machine. A clip up top keeps the trigger handle and wand attached, a pocket in back takes the 25-foot hose and the power cord, and a door in front holds the foamer. That matters more than it sounds. My gas equipment sheds accessories onto a shelf between jobs, and I lose 20 minutes hunting them down before each one. This one shows up at the wall complete.
Both nozzles in the box are wrong for siding
You want 25 or 40 degrees, and neither one is included
Home Depot lists siding right in the bullet points. The machine ships with two quick-connect tips, a 15-degree and a turbo, and neither belongs anywhere near vinyl.
A 15-degree tip concentrates the stream tight enough to gouge a panel or work it loose at the seams. The turbo is a 0-degree jet spinning in a circle, which is worse. Vinyl wants a 25-degree or 40-degree fan, which spreads the water wider and drops the force on any one spot to something the panel can absorb. Published guidance puts the working range for vinyl around 1,300–1,600 PSI, with a ceiling under 2,000. Some siding manufacturers restrict pressure washing in their care instructions. I just played it carefully and stood further back.
Mine puts out 2,100 PSI with no pressure dial, so tip choice and distance are my only throttle. Ryobi's own 7-piece quick-connect kit runs $39.97 and includes the 25- and 40-degree tips; the 5-in-1 nozzle covers the same patterns for $29.97. Buy one before the first wash, hold the wand 12–18 inches off the wall, and the number on the label never reaches the siding.
Angle the spray down and stay off the ladder
How water gets behind the panels
Vinyl is a stack of overlapping laps built to shed water running downward. Spray upward and you're driving water the one direction the system was never built to handle. It slips behind the panel, soaks the sheathing and any insulation back there, and you never see it happen. In Indiana, that water then gets a winter of freeze-thaw to work with, which is how a cosmetic job becomes a wall problem.
So the wand stays angled down, roughly 45 degrees, following the lap. Never up under the laps or into the trim. Clear the porch furniture and cover the outdoor outlets first. Work three or four feet at a time, foam from the bottom up so the detergent doesn't streak, then rinse from the top down and don't let anything dry on the wall.
Skip the ladder. A pressure washer kicks back when you pull the trigger, and a ladder is a bad place to take that. My ranch is single-story, so an extension wand reaches the peak from the ground.
The siding is a Saturday now, not an invoice
The machine cost me $199, plus a nozzle Ryobi should have put in the box, plus an afternoon. Against that: a service averaging $311 a visit, and a development down the road that guarantees I'd be booking more than one. I won't pretend a corded electric is right for every house. Two stories or badly oxidized siding put you in different territory, and there's no shame in paying someone else to climb the ladder. But for a single-story ranch with vinyl and covered areas that collect everything the wind carries, the job comes down to the right tip and a wand that points down.
