Honestly, buying one of these is my excuse to avoid actual elbow grease. ????
Tried the little cordless thing this weekend. It’s glorified water therapy.
Pros:
– No cords, no fuss
– Easy to stash in the trunk
Cons:
– Refill, refill, refill
– Makes me lazy about actual scrubbing
Anyone else get strangely proud of just blasting leaves off the porch and calling it clean?
Same here. Also, don’t forget protective gear — even light washers can fling debris. Learned that the hard way once ????
Totally. I tell myself it’s ‘maintenance cleaning’ and avoid real chores.
Haha—you’re not alone. These tools make light work feel satisfying. Just remember for stubborn stains, a bit of scrub + detergent still goes a long way.
Makita is the ‘best overall’ for a reason — very solid build and features. I do wish it was lighter though. If you’re a homeowner doing occasional jobs, it might be overkill, but for pros it’s worth the weight and cost.
Weight is the trade-off for durability and battery capacity. If you need lighter, check the Ryobi or the handheld Makita-compatible unit.
That’s a fair assessment. The Makita is targeted at pros and frequent users. Homeowners might prefer the Greenworks or Westinghouse depending on needs.
Quick question about the RYOBI RY120350: I need something to clean wood fencing and occasional patio tiles. Will 320 PSI/0.8 GPM be enough if I use the right nozzle and cleaner? I’m not expecting contractor-level blasts, but I don’t want to waste time.
Also is the siphon hose reliable when using a water tank on the back of a truck?
Make sure the siphon hose is tightened well. I lost suction one time because the strainer wasn’t seated properly — easy fix but frustrating mid-job.
Also watch battery level: pressure/spray consistency can drop as the battery discharges.
I’ve used the Ryobi with a 50L tank and it was okay for fence posts and light mildew. For deep stains you might want something with more PSI.
The Ryobi is aimed at light-to-medium jobs. For lightly soiled wood or regular maintenance it’s fine—use a wider spray and a cleaning solution to avoid gouging. The siphon hose works for tanks but performance drops compared to a pressurized feed; keep the tank close and elevated if possible.
Anyone tried the foam cannon compatibility between the Westinghouse and the Makita cordless options? I want a decent suds layer for cars but I’m worried about mismatch in fittings and pressure requirements.
I used a smaller foam bottle on my cordless and it made light suds — not the thick snow-foam you get from the big foam cannons, but enough for a quick car wash.
If thick foam is your priority, pair a proper foam cannon with a higher-flow machine like the Westinghouse or Makita (with adequate battery output).
Foam cannons often rely on a minimum flow/pressure to work well. The Westinghouse’s higher PSI/GPM is better suited for traditional foam cannons. Cordless handhelds can work with smaller foam dispensers but expect thinner suds. Check adapter fittings (M22 vs others) and consider universal adapters.
I'm considering the Makita DHW080ZK for my business, but I'm a bit worried about the extra cost for batteries and charger. Does anyone know if it's better to buy those separately or as a bundle?
I bought the Makita a few months back. I got the batteries separately since I already owned some compatible ones. It works out fine, especially if you can catch sales on batteries.
Buying batteries separately can be beneficial if you already have some, but bundles usually offer a discount. Consider your usage needs first.
I would recommend getting the battery and charger in a bundle if you plan on using it frequently. It saves you a bit in the long run.
I actually picked up that 700 PSI cordless Makita-compatible handheld (the budget one on the list) for quick car washes and it’s hilariously convenient.
It’s small, light and perfect for a quick rinse after a muddy hike. Downsides:
– Tank is tiny, refill often
– Not meant for heavy grime
– Hose length is annoying sometimes
Still, for the price you can’t beat the portability. ????
Would love to hear if anyone has modded one (longer hose or bigger tank?)
And remember safety — handheld units can still kick back; use two hands and protective eyewear if you’re experimenting with mods.
I used a small 5L jerry can with a gravity feed setup and it helped a lot. Still not professional, but saved me repeated fills.
Glad it works for quick jobs — some users have fitted larger inline tanks or used a drill-powered transfer pump to fill it faster between runs. Extending the hose is doable but be mindful of drop in pressure with longer hose runs.
I 3D-printed a larger cap adapter to fit a mason jar as an extra temporary reservoir. Totally ghetto but it worked for a weekend car show. ????
If you mod the hose, secure all fittings. I had a leak that sprayed me in the face once — learned my lesson ????
I’ve been eyeing the Makita DHW080ZK for a few weeks — the review makes it sound perfect for my weekend jobs. Two questions:
1) How long do the batteries usually last under load?
2) Any recommendations for which Makita batteries give the best runtime (capacity vs weight)?
Also, is the stepless pressure control easy to dial in when you’re switching between delicate surfaces and concrete?
I use 5.0Ah LXT cells with mine — about 45–60 min of pretty heavy work. If you’re doing continuous heavy blasting, definitely have a spare battery on the truck.
Good questions — the runtime depends a lot on battery capacity and the work intensity. Users report anywhere from 30–90 minutes on 5.0Ah packs for mixed work. If you need longer runtime, go for the higher Ah (e.g., 5.0–6.0Ah) even though they’re heavier. The stepless control is praised for fine adjustments, which helps when moving between surfaces.
Tip: balance weight vs runtime. I carry a charger in my van and swap batteries every 40 minutes on big jobs. Makes the Makita feel like it never stops.
Westinghouse ePX3100v seems like a great middle-ground for home users. The 2100 PSI is tempting for patio/driveway grime.
Has anyone bought this from an overseas seller and had plug or warranty issues? Also: do the 4-nozzle set and foam cannon actually come as decent quality accessories or are they cheap add-ons?
I bought mine from a local retailer and the accessories were fine for home use. Foam cannon worked well for car washes, but the wand felt a bit light for constant use.
Some buyers have reported receiving European plugs when ordering from international sellers—check the seller’s listing details and ask before purchase. As for accessories, they tend to be serviceable but not pro-grade; many users upgrade the wand/foam cannon if they need heavy-duty use.
Curious about using these with a water tank. From what I gather:
– Cordless units with a siphon hose (Ryobi/Makita cordless compatible ones) work ok off tanks
– Corded electrics like the Westinghouse need a power source but can you realistically run them off a generator on-site?
Anyone tried that combo? I’m planning a remote deck cleaning job and don’t want to lug a long hose.
I used a small inverter generator with a corded pressure washer once — worked fine, but the generator had to be beefy enough. Also, keep the generator away from dust and water splashes.
Good point about petrol models — not on the roundup list, but worth considering if you need continuous high-power cleaning off-grid.
If you’re doing lots of remote jobs, a petrol pressure washer is sometimes simpler — no batteries or generators. But heavier and more maintenance.
Yes, running a corded electric from a generator is common — just make sure the generator provides stable power and matches the washer’s plug/voltage. Cordless siphon-capable units are convenient but slower. Consider a petrol or inverter generator rated above the washer’s start/load wattage.
Greenworks 1700 PSI got the ‘budget-friendly’ badge and I can vouch: cheap, light and quiet. Did my bikes, patio furniture and a small driveway.
Constructive note: it choked on the really stubborn moss between paving slabs; had to go over a few times. Don’t expect miracles on thick grime.
Exactly — it’s ideal for maintenance cleaning. For heavy buildup, a higher PSI or chemical pretreatment helps. Also, a rotating turbo nozzle (if compatible) can make a big difference.
Agreed. For my house I use Greenworks most weeks and switch to a more powerful machine once a season for deep cleaning.
