Decent unit if you have an electric power washer and want to clean up a patio or driveway. If doing a huge space I would opt for something larger that can handle more psi on a gas unit, otherwise this is worthy especially at this price. I just snagged the 1800 PSI Greenworks from Lowes for $59.99 I am going to pair with this.

Well, if it's underpowered it only means the power washer is but not the caster. I don't believe that has anything to do with it... Seems like it just spins. If your washer has sufficient power it should spin faster.

What was your reason and what washer did you pair it with? The electric powered heads don't come with casters usually.

It's very underpowered, I'm returning mine as well.

I bought the same Greenwworks deal and was wondering if these work well at that lower PSI and water volume. I have a more powerful gas pressure washer with surface cleaner that works well, but am unsure this will be useful. Maybe if I had a deck, but I have just concrete surfaces to use this.

I use this with my SunJoe pressure washer and for this price it's worth it. Things to note: It will make the surface look uniform and makes the job so much easier, but you have to go slow, overlap your passes. It will not get those tough stains, you will have to go back with the wand to get those.

Bonus: I used it on large windows, cats and kids loved it. Don't remember if it got the window clean, it was more fun watching their reactions.

EDIT: while cleaning windows, cats and kids on the other side watching.

Works great. Needed something to pressure wash my garage floor and basement without spraying water everywhere. It's $20... People are complaining about it not being similar to ones am that are $80+ need to rethink what they're expecting.

Yeah, I could see being disappointed if you had a big pressure washer and were expecting a wide, deep clean. However, I just want to clean the winter crap off my tiny ipe deck in the spring. Beats using the green tip and going back and forth, back and forth. My FIL has a big washer and a wide one of these (I wanna say 20") that I can use for a deep clean of my driveway every few years, but frankly it's too much for my regular needs.

FYI, Best Buy has it for $22ish. Hopefully they'll price match since I have some rewards to use. https://www.bestbuy.com/site/gree...Id=6514915

I have a Ryobi 1900psi pressure washer and am thinking of getting a scrubber to clean up large pieces of moss on patio. Will this one be powerful enough? I used the Ryobi (strongest setting tip) to wash the moss before but it left quite a bit intact. Getting rid of moss in between pave stones work great though.
Wonder if this unit will help scrub away all the remaining moss on the patio slab.

Anyone know if it'll work with a Karcher K4? I don't have a stick like that I can attach it to??
