Car pressure washer with rechargeable batteries

Key Features

• Power source: Rechargeable lithium-ion batteries (common voltages: 18V, 20V, 21V, 40V, or dual-battery setups)
• Pressure: Typically 150–800 PSI (most real-world car-safe models fall in the 300–600 PSI range). Higher advertised numbers on cheap units are often exaggerated.
• Flow rate: Usually 0.5–1.5 GPM (or 100–220 L/h)
• Water source: Self-priming — can draw water from a bucket, tank, lake, or hose
• Runtime: 15–45+ minutes of continuous use per charge (depends on battery size, pressure setting, and model). Many come with 1–2 batteries.
• Nozzles: Multi-pattern (0°, 15°, 25°, 40°, fan, or 5/6-in-1 adjustable) + often a foam cannon/soap bottle
• Hose: Typically 5–7 metres (16–23 ft)
• Weight: Lightweight (often under 3–5 kg without batteries) for easy one-handed use
• Extras: Filters to protect the pump, carrying case, multiple spray tips
