Rated 5 out of 5 by from Powerful and efficient! This is my first power-washer, but I have been incredibly impressed with all the things I can do with it. From cleaning off the deck, and getting all the crud out from between the boards, to getting rid of built of dirt, cleaning my car, and blasting raccoons off my recycling bin. The possibilities are endless! I was worried that it might really kill my water bill, but at only 1.5 gallons per minute, its like flushing a toilet once a minute....and believe me...I've done that a few times in my life.

Rated 4 out of 5 by from Great product, cleans really well! The K4 is an awesome product. Disclaimer: I have never owned a power washer so this is my first! I had some vines growing on the side of my garage that stained the walls after I trimmed them. I dreaded the thought of cleaning it all with a sponge...until I put the K4 to the test. It cleaned out the dead plant debris and left the wall in great condition. The only small complaint is that the instruction manual is a little difficult to follow and I had attached the handle the wrong way for a few minutes until I rectified it. Otherwise it's a really good addition to my lawn, gardening, and cleaning tools.

Rated 5 out of 5 by from Easy to put together and easy to use! I have used but never put together a power washer out of the box before, so this was all new to me. However, the instructions were easy to follow and it was very easy to put together! We have used this pressure washer on our stone walkway, our concrete sidewalk, the brick on our house and we love it! It's easy to use and easy to manage - the cord doesn't get tangled or in the way and it's easy to maneuver around. We love this trusty pressure washer!

Rated 4 out of 5 by from Easy to use I've almost taken off a toe pressure washing before because the machine was so complicated to use and hard to maneuver but my K4 has been such a great purchase. I'm a mom on disability but my sidewalks and brick still need a good wash from time to time and this baby was out of the box fantastic. Very little kickback and easy to set up and stores beautifully.

Rated 5 out of 5 by from Household Necessity The K4 power washer arrived and within minutes my husband was able to add/assemble the few attachments. The washer has good pressure for everyday houshold use (ie washing windows, car, driveway and patio).

Rated 5 out of 5 by from Perfect powerfulness This pressure washer is awesome. Although not as powerful as a professional commercial one, this one is more that adequate for projects around the house. It's the perfect size and does an amazing job. I would definitely recommend this product.

Rated 5 out of 5 by from Therapeutic! So those videos on Facebook of people pressure washing stuff? They're so satisfying to watch - and it's even more satisfying when you're the one doing it! I was a bit intimidated to open the box and see all the bits and pieces, but it only took me 25 minutes from the time I opened the box until I was actually using it. It does an excellent job on everything I've tried so far (the deck, the outdoor furniture, the brick patio). The bricks were the most fun, they were covered in black/green mildewy goo and it came right off. It comes with two different wand attachments, one for lighter work like washing vehicles, and another for heavy duty pressure washing. The machine has a spot for keeping the tools onboard in between uses which is very handy. I do wish there was a way to keep the trigger pulled back, it did get tiring having to squeeze it but most people probably won't go crazy and do everything at once like I did. It was just so hard to stop once I got started...ha!
