The Lippert Flow Max 40V Portable Power Washer puts serious cleaning power in a 3-pound package. Two 40V lithium-ion batteries deliver up to 28 minutes of run time, the self-priming intake pulls directly from any open water source, and a 20-foot hose gives you real reach -- whether you're scrubbing your RV slideout at a campsite or rinsing down ATVs in the driveway.
Most pressure washers chain you to a garden hose and a 120V outlet. The Flow Max cuts both of those requirements. Drop the included pickup hose into a bucket, a stream, or your RV's fresh water tank, and the self-priming pump does the rest. Two included 40V lithium-ion batteries swap in seconds so you can keep working while one charges.
On the high setting you get 520 PSI and 0.67 GPM -- enough to blast road grime off a tow vehicle, clean a concrete patio, or rinse mud off bikes and camping gear. Dial it down to ECO/low mode for 320 PSI and 0.53 GPM when you're rinsing a car finish, washing windows, or watering plants without stripping them.
High mode: 520 PSI / 0.67 GPM for stubborn grime. Low (ECO) mode: 320 PSI / 0.53 GPM for delicate surfaces and extended run time.
Submersible pickup hose draws from any water source -- bucket, tank, creek -- so you can clean off-grid with no hookups at all.
Two rechargeable 40V lithium-ion batteries provide up to 28 minutes total run time. Charger and accessories bag are included in the kit.
Spray gun, 25 oz refillable soap bottle, 20 ft intake hose, accessories bag, battery charger, and 3 interchangeable nozzles -- everything ships in the box.
The kit includes three interchangeable nozzles and a 6-position spray attachment with a long, rotatable nozzle so you can match the spray pattern to the job. Positions typically cover 0-degree (concentrated jet), 20-degree, 40-degree, shower, foam (with soap bottle attached), and rinse patterns. When washing vehicles, Lippert recommends ECO mode with the 20 or 40-degree tip for rinsing, and the foam/shower setting with soap for the wash cycle.
At just 3 lbs the Flow Max tucks under an RV seat, in a basement bay, or on a garage shelf without taking up meaningful space. The included accessories bag keeps nozzles and the soap bottle together so nothing goes missing between trips.
