Who is it Suitable For?

This pressure washer is great for anybody who needs a long-lasting, consistent way to clean outdoor surfaces and furniture without having to rely on manual cleaning methods or gimmicky, easily-broken equipment. The wheels make it easier to move around, so you’ll be able to take it around the entire outside of your house without needing to tire yourself out carrying it around, which makes it a useful tool for larger homes with a lot of outdoor space.

The durable frame also means that it’s more suited to outdoor use than many other models and designs, making it much more useful in poor weather or climates that aren’t kind to most pieces of outdoor electric technology.

Since it’s powered entirely through electricity, you don’t need to constantly fill it up with more fuel – you can plug it into an outdoor power line or power source and run it straight from there. his also gives a similar amount of mobility so you won’t be limited in your movements thanks to the cable.

Why we like it

The Karcher K5 is a simple concept, essentially being a compact electrical pressure washer that’s been given a much more durable and versatile body, but it’s much more versatile than it might initially seem. The strong motor and high PSI make it incredibly powerful when used in the right way, and it can easily catch up to similar Karcher gas-based pressure washers without any of the downsides or side effects that they bring with them.

It’s also much quieter thanks to the engine itself, meaning that you won’t have to deal with any obnoxious noises if you’ve got a big cleaning session ahead of you. Of course, Best of Machinery can’t tell you what to think – take some time to think about whether or not it’s right for you.

No product is perfect for everybody, but the Karcher K5 definitely seems to stand out above its peers, especially when it comes to the variety of different situations it can be useful in. If you’re looking for a powerful, durable and reliable electric pressure washer, though, this might be just the product for you!
