Product Details
Most sprayer problems don't show up until you're already mid-job. You run out of hose halfway down the fence line. The plastic wand starts weeping where it meets the handle. You need a free hand and you don't have one. The Pro Kit is the HD4000 with those three problems already solved. The 20-foot braided hose lets you set the pack down and work a full circle around it. The stainless steel wand handles bleach, solvents and anything else that chews through plastic. The HD spray pistol takes over for close-up and one-handed work. Underneath, it's the same sprayer: 6-8 hours of runtime, 200+ gallons per charge, a digital battery meter, a translucent tank with gallon markings, and a wide-mouth lid for clean refills. Same one-year warranty, same US-based support
Product Care
Fully empty and clean the tank before storing, then keep the sprayer in a cool dry place away from direct sunlight and freezing temperatures. For extended storage, remove the battery to preserve its lifespan and prevent gradual drainage. Run clean water through the 20-foot hose until it comes out clear, then hang it in loose coils instead of folding it so the braid doesn't kink. Rinse the stainless steel wand and spray pistol inside and out after any chemical use and let both dry fully before storing. Wash the PVC gloves with soap and water and store them flat.

LESS STOPPING. MORE SPRAYING.
8 INTERCHANGEABLE NOZZLES FOR EVERY APPLICATION
Stop buying a separate sprayer for every task. The HD4000 Pro Kit includes eight professional-grade nozzles that cover every spraying situation:
Shower head: Gentle, rain-like coverage for delicate plants
Adjustable: Twist from fine mist to concentrated stream instantly
Double-mist: Ultra-fine droplets for even coverage
Single-mist: Precise spot treatments and targeted applications
Fan flat: Wide, uniform spray pattern for large areas
Brass: Heavy-duty durability season after season
Swapping takes seconds and needs no tools. One sprayer handles weeds, feed, pest control and spot work, so nothing sits unused in the garage.
Traditional sprayers leave you with aching shoulders and a sore back inside an hour. The Pro Kit gives you two ways out of that:
Double-padded shoulder straps distribute the full 4-gallon load evenly
Cushioned back pad with airflow design reduces sweaty discomfort
Locking trigger keeps your hands relaxed during extended use
20-foot hose lets you set the pack down and spray without carrying it
On long jobs you can work off your back entirely. Drop the tank in the middle of the area and cover everything within a 20-foot radius. Most people notice it around hour three, when other sprayers have them looking for somewhere to sit.
REACH HIGHER. SPRAY FARTHER.
Stop climbing ladders or leaving tall areas untreated. The Pro Kit is built for reach in every direction:
34.5-inch extendable stainless steel wand reaches tall shrubs and fruit trees from
ground level
20-foot braided hose covers a full circle around the tank without moving it
Adjustable 40-90 PSI boosts spray distance to hit far targets
HD spray pistol takes over for low beds and close-in work
The 20-foot hose is five times the standard length, so the tank stays parked while you work fence lines, beds and eaves. Maximum extension holds an accurate spray pattern, so you get precision at every height.
NO DRIPS. NO LEAKS. JUST A CLEAN SPRAY EVERY TIME.
This build is made to stay sealed and dependable through repeated use. Metal fittings and a steel wand remove the failure points that make cheap sprayers weep:
Stainless steel wand resists the cracking that splits plastic wands at the handle
Metal hose fittings stay tighter and hold up longer
Braided hose construction resists kinking, splitting and pressure loss
Quick-connect pistol seals clean, with no drip between swaps
Less product on your boots and more on the target. Nothing here needs constant tightening or adjusting between jobs.

How long does the battery last on one charge, and about how many gallons can I spray per charge?
On a full charge, you can expect about 6-8 hours of runtime. In real-world use, that translates to 200+ gallons per charge, depending on your nozzle choice and pressure setting.
Yes, it includes the battery and the charger. A full recharge is typically around 8 hours, so just plug it in overnight, and it’s ready the next day.
Most weak flow issues are simple fixes. First, rinse the nozzle tip, then check the filter screen (it’s designed to catch debris before it reaches the nozzle). After that, make sure the hose connection is snug and the tank is clean.
PetraFlow Nozzle choice absolutely affects spray distance and pattern, and using the recommended nozzles is the easiest way to keep performance consistent over time.
You control output in two ways: (1) adjust the pressure (40-90 PSI) and (2) swap nozzles for different patterns. The nozzle can be twisted from fine mist to a more concentrated stream, so you can fine-tune quickly while you work.
It’s built for common lawn and garden applications like fertilizers, weed killers, herbicides, pesticides, and foliar feeds, and it’s described as chemical-resistant for that type of use. If you’re spraying a stronger/caustic solution, using the recommended nozzle for that purpose helps keep things running smoothly.
A quick rinse routine keeps it performing like new: empty the tank, then run warm soapy water through the system (tank → hose → wand → nozzle). Finish with a clean-water flush, and let components air-dry before storage. This prevents residue buildup and future clogs.
Is it comfortable for longer jobs (weight, padded straps/harness), and is it designed to reduce fatigue?
Yes, it’s made for longer sessions with double-padded shoulder straps and a cushioned back pad. It also includes a locking trigger, which gives your hand a break during extended spraying.
