A surface cleaner is a round hood with spinning nozzles underneath — it turns your pressure washer from a paint-stripping pencil into a floor buffer for concrete. Even coverage, fixed safe height, double the speed. If you wash flatwork even once a year, it's the single best upgrade you can buy. Here's how to choose one that matches your machine.
Our picks at a glance
- Best for most homeowners: a 15" surface cleaner — the sweet spot of speed and maneuverability
- Best for big driveways & patios: a 20"+ model with wheels — covers serious square footage
- Best for electric washers: a compact 11-12" cleaner — sized for lower GPM machines
- The upgrade pros use: stainless housings — survive years of commercial abuse
The one spec that decides everything: match it to your machine
Surface cleaners are sized by your washer's output, not your ambitions. A big hood needs enough water and pressure to spin its bar and still clean: as a working rule, electric washers (1,500–2,000 PSI) run 11-12" hoods well; mid-size gas machines (2,500–3,200 PSI) drive a 15" beautifully; and 3,000+ PSI / 4 GPM machines earn the 20"+ decks. Oversize it and you get a slow, streaky spin that defeats the whole point. Check your washer's PSI and GPM sticker before buying — it's the whole decision.
Features worth paying for
- Wheels or casters: on 20"+ hoods they're the difference between gliding and dragging. On 15" models, nice but optional.
- Stainless or aluminum housing: plastic hoods work fine for a few seasons of home use; metal is what survives commercial life. Buy plastic for one house, metal if you're ambitious.
- Replaceable nozzles and swivel: the two parts that wear. Models with standard replaceable tips outlive sealed cheapies twice over.
- Edge visibility: some hoods have notched skirts so you can see your line against walls and borders — handy on patios.
Pro technique in one paragraph: pre-treat with concrete cleaner and let it dwell, run the surface cleaner in slow overlapping passes like mowing a lawn, then rinse down-slope with a wide fan tip and detail the edges with the wand. The chemical does the cleaning; the hood does the evenness; your patience does the rest. Full method in our driveway guide.
What a surface cleaner won't fix
Deep oil stains (those need a dedicated degreaser and dwell time), paint, and irrigation rust. And it's for flatwork only — decks and siding still get the wand at gentle settings. Everything mentioned here lives on our Cleaning & Exterior board.
