The short answer
A 15-inch surface cleaner is the right size for most residential pressure washers. Match the cleaner's GPM rating to your machine: electric washers need a 1.5–2.0 GPM-rated cleaner, gas washers need 2.0–2.5 GPM or higher. Karcher, Simpson and Greenworks make reliable homeowner models.
Karcher 15" Surface Cleaner
The standard 15-inch cleaner for electric and small gas washers — sealed, glides well and connects via 1/4-inch quick-connect.
If you have ever pressure-washed a driveway with a wand, you know the pattern: clean stripes separated by slightly less clean stripes, plus the occasional gouge where you paused for a second. A surface cleaner fixes all of that by holding two nozzles at a fixed height and spinning them in a wide path.
How Surface Cleaners Work
A surface cleaner is a round hood with a spinning bar underneath. Two nozzles point down and rotate, spraying a consistent width as you walk. The hood keeps overspray down and the fixed height prevents the pressure from concentrating in one spot.
| Pressure washer | GPM | Cleaner size | Cleaner GPM rating |
|---|---|---|---|
| Light electric | 1.2 – 1.5 | 12 – 14 in | 1.5 – 2.0 |
| Mid electric / small gas | 1.6 – 2.0 | 14 – 15 in | 2.0 – 2.5 |
| Homeowner gas | 2.3 – 2.5 | 15 – 18 in | 2.5 – 3.0 |
| Pro gas | 3.0+ | 20 – 24 in | 3.0+ |
The Picks
Karcher 15" Surface Cleaner
The standard recommendation for electric and small gas washers. It is well-sealed, the bristles glide over uneven concrete and it connects via a standard 1/4-inch quick-connect. Match it to washers up to 2.5 GPM.
Simpson 15" Surface Cleaner
Built for gas washers with higher flow. The steel construction is heavier than the Karcher but holds up to weekly use. A good pairing for 2.5+ GPM machines.
Greenworks Surface Cleaner
A budget-friendly 11-inch option sized for electric washers. It cleans smaller patios and walkways well, though it bogs if you push it faster than the washer can supply water.
Frequently Asked Questions
- Can I use a surface cleaner on pavers?
- Yes, but keep the pressure moderate and move steadily. The fixed nozzles are gentler than a wand, but a high-GPM gas washer can still wash out sand joints.
- Do surface cleaners work on wood decks?
- No. The spinning bar is too aggressive for wood grain and will leave swirl marks. Use a wand with a 25° or 40° nozzle on decks.
- Why is my surface cleaner leaving streaks?
- Usually the bar is spinning too slowly because the GPM is too low, or you are walking too fast. Slow down and check the GPM match.
