Our Verdict on Sun Joe SPX3500

Sun Joe SPX3500 offers an efficient way to clean the exterior of your home. Sun Joe SPX3500 is light and has a long power cord, making it perfect for everyone from homeowners to apartment dwellers. In addition, sun Joe SPX350 provides plenty of pressure even in cold weather – great for winter!

What to Expect from Sun Joe SPX3500

– Power and performance for tough jobs.

– Pressure washer is easy to maneuver and transport with an integrated carry handle.

– Trigger gun provides user-friendly front-facing controls. That makes switching between various settings easier or turning off quickly when needed.

– Detergent tank holds up to 1.2 liters of detergent.

– Lock-On / Lock-Off trigger prevents accidental activation. It prolongs the pump’s life and reduces fatigue during extended use; the Total Stop System automatically shuts off water flow when the trigger is not engaged in the ON position.

– Adjustable spray nozzle provides for prospective cleaning.

– Flexible hose with an integrated cord makes it easier to reach all around your home or workspace without unplugging or moving the pressure washer itself. An extended power cable covers a greater surface area, making Sun Joe SPX3500 perfect for indoor and outdoor use.

Portability of Sun Joe SPX3500

– Integrated, foldable carry handle makes it easy to transport.

– Large wheels make moving Sun Joe SPX3500 even more accessible; for indoor use only – do not roll over the hose with this unit!

Ease of Use

Although we dock some points for a few tiny details, the SPX3500 was awarded a solid score for this metric. First of all, the hook on the back of the machine is pretty shallow, so you need to have some good cord-wrapping skills to keep it all bundled up.

 There’s also nothing that secures either the cord or the hose. So they tend to flop around during transport. Some models have a velcro strap or a bungee to deal with this issue. The high-pressure hose on the SunJoe SPX3500 is only 20 feet — it’s one of the shortest we’ve seen. However, the 35-foot power cord helps.

The noise of Sun Joe SPX3500

– The induction motor operates at a slower speed than traditional motors, producing less noise and vibration.

– The noise levels dropped to 65.20 dB when Sun Joe SPX3500 was placed at a distance of 25 feet compared to the SPL meter showing 70 decibels just next to it.

– Our judges did not find any annoying sounds emitted by this model, and we love that it only makes noise when the trigger is depressed.

– This model is ideal for use in bathrooms or other areas where quiet operation is necessary.

Maintenance of Sun Joe SPX3500 

– No tools required: attach your garden hose, and you’re ready to go.

– Keep the nozzles clean and free from debris for optimal performance.

– Ensure the detergent tank is emptied after each use and there’s enough water in your unit when operating Sun Joe SPX3500.

– Use only the manufacturer’s recommended detergents or soaps with this product: never mix different chemicals, as this may affect the performance of your unit.

– Store indoors when not in use during cold weather periods or clean before storage to protect the pump from damage due to sediment buildup.

What can we clean with Sun Joe SPX3500?

– Sun Joe SPX3500 is ideal for cleaning vinyl, tile, and grout.

– The variety of nozzles allows you to choose the perfect amount of pressure depending on your project at hand. For example, a low 0° nozzle produces a gentle mist. At the same time, higher psi settings can strip paint from metal surfaces or remove tough stains from concrete driveways and sidewalks.

– Sun Joe SPX3500 is versatile enough to clean various surfaces, including cars, boats, RVs, or motorcycles!
