VEVOR Battery Powered Backpack Sprayer with Cart, 0-94 PSI Adjustable Pressure, 4 Gallon Tank on Wheels, I ordered this 4 gallon sprayer for lawn care. Overall I'm pleased with the sprayer. The following review is after I filled it with 4 gallons of water to test overall operation before filling with chemicals. I paid $110 for the sprayer and another $55 to make adaptations to make it user friendly. Likes: Lots of things to like including numerous spare parts including: O-rings, rubber seals %26 washers and numerous spray nozzles. Rechargeable Battery that is removable %26 replaceable. On wheels with an adjustable height pull handle Hose relatively easy to connect %26 disconnect 15' hose with numerous sprayer nozzles The trigger on the spray wand works great. I like the on/off switch location. There is a dial that allows you to adjust the pressure and volume of spray. Problems: - The 6" wheels means the bottom of the sprayer is only about 1" above ground. It rolls great on the driveway but hangs up on even low cut grass. I had trouble pulling it across the lawn and it even pulled out of my hand several times. I considered replacing the 6" wheels with 8" wheels but the wheels would then rub the hose. - The included 15 foot hose is too long for spraying while towing the sprayer (it gets in the way while towing) and way too short if you want to park the sprayer and walk around while spraying. ->> The hoses do not have swivel connections so while maneuvering to spray one or both ends of the hose unscrews from the sprayer and spray wand, leaking everywhere. The only way you know it's leaking is you hear the pump turn on and off as the pump is having difficulty holding pressure. Modifications: We need swivels on the hose so it doesn't unscrew and leak and since raising the ground clearance is a problem, we need a longer hose so we can park the tank and wander around with a hose. Total adaption cost: about $55 The sprayer outlet is metric (M14x1.5) as is the connection at the spray wand. Meaning the ends of the 13' hose are also M14x1.5). I created a this solution: - Replaced the 13' hose with a 50' hose - adapters on the tank outlet and at the wand end with 1/4" NPT or MIP threads. - Hose, I used 1/4" NPT hose, 50 feet, air hose from $29. - Quick couplers on the ends of the air hose for faster connect/disconnect ($16 total) The quick couplers provide swivels so the connections won't unscrew and leak. Adapter: $13 - 2Pcs 304 Stainless Steel Forged Pipe Fitting, M14x1.5 Female to 1/4" NPT Male Thread Adapter Hex Pipe Fitting Adapter Overall I'm pleased with the sprayer. I have a backpack 4 gallon sprayer and it's a pain to put on and take off. It often leaks all down my back and it wears me out carrying it around. I have to fill it three times to treat my 12,000 sq foot property so having a sprayer on WHEELS is great. The 50 foot hose will allow me to tow to the middle of the lawn and then walk around to spray.
