- 5 quick-connect spray tips including a wide 40-degree fan
- Dual detergent tanks for deck cleaner and rinse-aid
- TSS auto shutoff
- 20-foot hose, 35-foot power cord
Strengths
- Included 40-degree wide fan tip is the gentlest option in the box, well suited to softwood decking
- Dual detergent tanks make it easy to run a dedicated deck cleaner without swapping containers
- Widely reviewed and easy to find replacement nozzles and parts if one wears out
Limitations
- No dedicated low-pressure deck mode, output control depends entirely on nozzle choice and distance
- 2030 PSI still requires discipline on aging or already-weathered boards
- Plastic housing feels less durable than the Karcher K5's build over years of seasonal use
Key specs: 1500 max PSI, 1.2 GPM, Upright hand-carry design, Turbo nozzle included.
Key Specifications & Features:
- 1500 max PSI, 1.2 GPM

- 35-foot power cord
- 13-Amp motor
Strengths
- 1500 PSI ceiling is the closest of any model here to the generally recommended safe range for softwood
- Lightweight, hand-carry design is easy to move around a deck without dragging a cart
- Compact enough to store in a closet between seasonal uses
Limitations
- 1.2 GPM flow means slower rinsing on a large deck versus higher-GPM units
- No included wide fan-tip specifically marketed for wood, relies on the turbo nozzle used carefully at distance

Key Specifications & Features:
- 2000 PSI, 1.4 GPM

Limitations
- Costs meaningfully more than the Sun Joe or Greenworks options
- 1.4 GPM flow is lower than the Sun Joe SPX3000's 1.76 GPM, so rinsing large decks takes a bit longer
- Bulkier housing than the compact Greenworks GPW1501
RYOBI
