Getting started with your HydroBlast.
The five things most people ask in the first ten minutes after opening the box.
How do I charge the battery the first time?
Slide the 18 V battery out of the base of the unit and connect it to the included USB-C wall charger. A full charge from empty takes about 70 minutes. The charge indicator turns solid green when the battery is full. You can use the unit while the battery is charging in the base, though runtime will be limited to the charger output.
How do I attach the garden-hose adapter?
Screw the 3/4 in. GHT quick-connect adapter onto the threaded inlet on the side of the unit, then click your garden hose onto the adapter. Turn the hose on at the spigot before pulling the trigger so the pump primes from a pressurized source.
How do I attach the bucket intake hose?
Remove the garden-hose adapter. Push the 20 ft. self-priming intake hose onto the inlet barb until it clicks. Drop the weighted, filtered end into your bucket, rain barrel, or other open freshwater source, then squeeze the trigger. The pump primes itself within 5–10 seconds.
How do I install the foam-soap reservoir?
Pull off whichever nozzle is currently on the wand. Fill the foam reservoir with a 4:1 water-to-detergent mix using a mild car-wash or all-purpose detergent — no bleach, solvents, or industrial cleaners. Twist the reservoir onto the wand and select Standard mode for the best foam pattern.
The unit isn't drawing water — what should I check?
First, confirm the water source is connected and turned on. If you're using the intake hose, make sure the filter is fully submerged and the hose has no kinks. Hold the trigger for 10 seconds to let the pump self-prime. If it still won't draw, detach the inlet and check for debris in the filter, then reattach and try again.
Nozzles, storage, and day-to-day use.
Practical guidance for getting more out of the unit and keeping it in good shape.
Which nozzle should I use for which surface?
Fan-spray is the everyday choice for siding, decks, vehicles, and outdoor furniture. Pinpoint-jet concentrates pressure for grout lines, wheel wells, and stuck-on grime — keep it at least 12 inches from painted surfaces. The rotary brush is best for cars, bikes, and any surface where you want gentle agitation. The foam-soap nozzle is for pre-soak with detergent.
How do I clean the rotary brush head?
Pull the brush head off the wand, rinse the bristles under running water, and let it air-dry before storing. If detergent has dried in the bristles, soak the head in warm water for a few minutes first. Do not put the brush head in a dishwasher.
Can I leave the battery in the unit between uses?
Yes, if you store the unit indoors at room temperature. For storage longer than a few weeks, charge the battery to about 50% and remove it from the unit. Avoid leaving the battery installed in a hot vehicle or unheated shed.
What's the best way to store HydroBlast?
Drain residual water from the pump by running the unit for 5–10 seconds with no water source connected, then release the trigger. Wipe the housing dry, coil the intake hose loosely, and store the unit indoors. The included box works well for long-term storage.
Can I use it in winter or outside the operating-temperature range?
The operating range is 34 °F – 104 °F (1 °C – 40 °C). Below freezing, residual water in the pump can expand and damage internal seals — drain the unit fully before any cold-weather storage. In hot conditions above 104 °F, motor performance drops and runtime is shorter.
