Fanttik Pressure Washer Manual: NB8 Ultra, Fold, Nano, Flip & NB10

This is the manual hub for the Fanttik NB cordless pressure washer line — the NB8 Ultra, NB8 Fold, NB8 Nano, NB8 Flip, and the NB10 Fold. Below you'll find where to download each user manual, the confirmed specs for the NB8 Ultra, how to set up and prime the washer, the nozzle and mode guide, and charging and storage rules. These cordless washers draw from any open water source (a bucket, barrel, lake, or tap) rather than a pressurized hose connection, so first-time setup differs from a wall-powered washer.

Where to Find the Manual (PDF Downloads)

Fanttik publishes the NB8-series manuals as downloadable PDFs — no registration required. Download the one that matches your model:

• NB8 Ultra: Fanttik NB8 Ultra User Manual (PDF)
• NB8 Fold: Fanttik NB8 Fold User Manual (PDF)
• NB8 Nano: Fanttik NB8 Nano User Manual (PDF)
• NB8 Flip: Fanttik NB8 Flip User Manual (PDF)
• NB10 Fold: A standalone PDF is not yet published. Refer to the NB10 Fold product page for current specifications, and contact Fanttik Support for the latest documentation.

A printed quick-start card also ships in the box. The full PDF covers certification details, maintenance, and the complete accessory list that the printed card omits.

These figures are confirmed from the NB8 Ultra product page. Other models in the line share the same cordless, water-source-fed design but differ in tank size and form factor — check each model's manual for its exact numbers.

First-Time Setup & Priming

A cordless pressure washer must pull water from an open source before it can build pressure. Skipping the priming step is the most common reason a new unit seems to "run dry."

1. Charge fully before first use. Connect the supplied cable to the charging port and a wall adapter. The LED indicator shows charge progress. A low battery limits the pressure the pump can reach.
2. Drop the inlet filter into your water source. Submerge the weighted filter end fully in a bucket, barrel, or other open water. If it floats above the surface, the pump draws air instead of water.
3. Connect the hose and spray gun. Attach the high-pressure hose to the outlet and the spray gun to the other end. Push connectors until they click or seat fully.
4. Fit a nozzle. Select the spray angle for your task (see the nozzle guide below) and lock it onto the gun.
5. Prime the pump. Power on and squeeze the trigger. It takes a few seconds for water to travel up the inlet line and purge trapped air — the spray will sputter, then stabilize into a steady stream.
6. Start on the lowest mode. Confirm a clean stream before stepping up to higher pressure.

Nozzle & Mode Guide

The NB8 Ultra ships with a 5-in-1 nozzle. Match the angle to the surface — wider angles are gentler, narrower angles concentrate force:

• 0° (spot): Maximum concentration for stubborn, caked-on grime. Keep it moving and well back from soft surfaces.
• 15° (small area): Tight, focused cleaning on small patches.
• 25° (medium area): General-purpose angle for cars, bikes, and equipment.
• 40° (garden): Wide, soft spray for rinsing, watering, and delicate surfaces.
• 65° (foam): Applies detergent or foam for pre-soaking before the rinse pass.

On the NB8 Ultra you can also switch electronically between Low (300 PSI), Middle (500 PSI), and High (725 PSI) on the LED screen. Use Low for cars and painted surfaces, High for concrete and heavy grime. The NB10 Fold and other models use the same 5-in-1 nozzle concept; confirm your model's available pressure modes on its LED display.

Charging, Storage & Winterizing

All NB-series washers use a built-in rechargeable battery; the NB10 Fold charges over Type-C.

• Charge before storing. Don't leave the unit empty for long periods on a depleted battery.
• Drain after every use. Run the pump a few seconds with the inlet out of the water to clear the lines, then empty the hose and gun. Standing water breeds residue and, in cold climates, can freeze and crack components.
• Rinse the inlet filter. Grit on the filter screen reduces flow and can starve the pump. Rinse it clean and let it dry.
• Store indoors, out of frost and direct sun. Fold the foldable models flat to save space.

FAQ

Q: Where do I download the Fanttik pressure washer manual?
A: Use the model-matched PDF links in the section above. The NB8 Ultra, NB8 Fold, NB8 Nano, and NB8 Flip each have a hosted PDF. The NB10 Fold has no PDF yet — see its product page or contact support.

Q: What is the max pressure of the NB8 Ultra?
A: Up to 725 PSI, with three selectable modes: Low 300 PSI, Middle 500 PSI, and High 725 PSI.

Q: How long does the NB8 Ultra run on a charge?
A: Up to 58 minutes, powered by a 4000 mAh battery. Higher pressure modes draw more power and shorten runtime.

Q: Do I need a tap connection?
A: No. These are self-priming cordless washers that draw from any open water source — a bucket, barrel, lake, or tank. Submerge the inlet filter fully before triggering.

Q: The spray sputters and won't build pressure — is it broken?
A: Usually not. It means air is in the line. Keep the inlet filter fully submerged and hold the trigger a few seconds to prime. If it still won't build pressure, see Fanttik pressure washer not turning on.

Q: Can I use it while charging?
A: Charge fully, then unplug and operate. Don't run the unit with the charger connected.
