Rated 1 out of 5 by from Not Happy I purchased this power washer to replace my older Karcher. I like the size and the mobility of the product. However none of my attachments fit this machine. I have an extension wand which doesn’t fit this washer! And yet it says it has universal fittings. Very disappointing! I will be returning this machine! Buyer beware!

Rated 4 out of 5 by from Great for smaller household jobs We've used this on our driveway, patio, brick around the house...it does a great job of removing stains/dirt/algae and making everything look fresh and clean. I've been pleasantly surprised by the performance. It's not heavy, so it's easy to move around without a huge hassle.

Rated 5 out of 5 by from Great Pressure Washer I love all of the things on the outside of my house that I've cleaned with this item. I can not only clean my siding, deck, and steps, but I've also used this to wash my vehicle. I would definitely recommend this item.

Rated 5 out of 5 by from Wow wow wow I am completely amazed by this pressure washer. It is the second I've owned and wow! This one us so very efficient and powerful. My last one took forever to complete a simple job. This one is much faster and does the job much much better.

Rated 4 out of 5 by from Easy to use, lightweight, very effective Washer was easy to assemble and use. Lightweight design is easy to move around and different nozzle tips make different tasks easy. Great overall, could use a larger soap reservoir to avoid frequent refills.

Rated 5 out of 5 by from So easy to use! This is the first pressure washer I’ve ever owned and was thrilled to try it out. First of all, it’s very lightweight and easy to use. Assembly was a breeze and I really liked how it’s compact and doesn’t take up a lot of storage space. We used it on the car because of all the snow we get, it took off all the salt and the car looks new again! I really like the soap option. I really enjoyed using this and am looking forward to trying it out on other things once the weather breaks. Definitely recommend to family and friends!
