Who It's For
This portable cleaner is ideal for apartment dwellers and renters who lack access to outdoor taps and power sockets. It's a must-have for car enthusiasts, mountain bikers, and campers who need to rinse off mud before heading home. It also suits home gardeners who want a lightweight, quick-grab tool for washing down patio furniture, muddy boots, and garden tools β without unwinding a massive hose reel. Dog owners, boat enthusiasts, and off-road riders will find it equally indispensable.
Usage Tips
- Keep the filter fully submerged in your water bucket to ensure a steady, uninterrupted water flow.
- Snap on the foam pot attachment first to soak your vehicle in soap β let it dwell for 2β3 minutes to break down dirt before rinsing.
- Use the 40-degree wide-angle nozzle for delicate surfaces like car paint and outdoor furniture.
- Switch to the 0-degree direct-line nozzle to blast packed mud from tyres, stone pathways, or bike frames.
- Hold the trigger for about 10 seconds on first use to prime the pump and allow water to travel up the 5-metre hose.
Frequently Asked Questions
Can I draw water directly from a lake or stream without damaging the pump?
Yes. The kit includes a specialised filter attachment that fits onto the end of the hose. Always ensure this filter is attached and fully submerged to prevent grit, sand, or algae from entering and damaging the internal motor.
How long does a single battery last during continuous spraying?
Each 1500mAh battery provides approximately 20β30 minutes of continuous spraying time, depending on the nozzle setting used. With two batteries included, you get up to an hour of total runtime β enough for washing an SUV or a large patio area.
Can I use hot water in my bucket to help remove winter road salt and grease?
We recommend cold or lukewarm water (up to 40Β°C / 104Β°F). Using boiling or very hot water can warp internal plastic components and damage the high-performance water pump.
Is the water pressure safe to use on bicycles and motorcycles?
Absolutely. While powerful enough to blast away mud, the pressure is lower than a heavy-duty mains-connected washer. Using the 40-degree wide-angle nozzle, you can safely clean your bike without forcing water into sensitive wheel bearings or suspension seals.
Does the foam pot work with standard car shampoo, or do I need special snow foam?
The foam pot works with any standard liquid car shampoo. For the thickest, most clinging suds, use a dedicated snow foam liquid mixed with a little warm water in the pot.
What's in the box?
The kit includes: 1x pressure washer unit, 1x 5m water hose, 2x 21V 1500mAh batteries, 1x battery charger, 1x extension rod, 1x 0Β° nozzle, 1x 40Β° nozzle, 1x foam pot, 1x water pipe connector, and 1x filter.
Can I use this to rinse my dog after muddy walks?
Yes β fill a bucket with lukewarm water, attach the gentle 40-degree wide-angle nozzle, and it works brilliantly as a portable pet shower. Much less stressful for dogs than a full bath, and far easier than wrestling with a garden hose.
Is it suitable for cleaning garden tools and patio furniture?
Absolutely. It's ideal for blasting soil off spades, forks, and trowels, and for rinsing down plastic or metal patio furniture at the start and end of the season. The wide-angle nozzle is recommended for furniture to avoid marking surfaces.
How do I charge the batteries?
The included charger accepts AC 110β240V at 50/60Hz, making it compatible with standard household sockets worldwide. Simply remove the battery from the unit and plug it into the charger. A full charge typically takes 60β90 minutes.
Can I use this on a boat to rinse off saltwater?
Yes β it's excellent for boat owners. Fill a bucket with fresh water and use it to rinse saltwater from decks, outboard motors, and fishing equipment after a day on the water. The compact size makes it easy to store on board.
π‘ Did You Know?
A traditional garden hose running at full flow uses approximately 10β15 litres of water per minute. This cordless pressure washer draws water on demand only while the trigger is held, making it significantly more water-efficient β a smart choice for areas with hosepipe restrictions or water conservation goals.
