It includes two spray lances, a high-pressure gun, Vario Power spray lance, and a dirt blaster. Quick Connect connections simplify swapping nozzles, making it a practical choice for decking maintenance where precise cleaning is needed without over-spraying surrounding areas.

Buying Guide
- Decking material and condition: Timber decking benefits from adjustable pressure, gentle spray options for fragile boards, and detergents that help remove moss without causing surface damage. Look for models with multiple nozzles or adjustable pressure settings.
- Mobility and storage: If you have a small garden, a unit with a built-in trolley or compact design helps you reach all areas without fatigue. Consider hose length and overall weight when moving around a deck.
- Detergent compatibility: For decks, a detergent-compatible model that can mix and suction cleaning agents can improve mould and moss removal, while safeguarding timber sealants when used as directed.
- Ease of use and durability: Quick-connect nozzles, ergonomic handles, and sturdy build quality reduce effort during cleaning sessions and extend device life, especially with outdoor exposure.
- Smart features and support: Apps offering usage guidance, maintenance tips, and service portals can help beginners achieve better results and keep equipment in good condition.
- Noise and water efficiency: Deck cleaning sessions are more pleasant when the unit operates with reasonable noise and water efficiency, particularly in shared spaces or near neighbours.
How To Choose For Your Deck
For decks, aim for a model that balances power with control. A pressure range corresponding to residential use (roughly 100–120 bar) is typically sufficient for removing moss and built-up grime from timber without causing surface damage. Look for adaptable spray patterns and detergent options to manage different degrees of soiling. A compact design or trolley helps you cover larger decking areas with less effort, while durable hoses and fittings reduce the risk of leaks during cleaning.
