The Bosch Universal Aquatak 135 pressure washer claims to provide 'fast, flexible, and effortless cleaning' for a wide range of cleaning tasks. Whether you're looking to remove grime from patios, garden furniture, cars or gutters, it offers different settings to handle each task. It also comes with a high-pressure detergent nozzle to make cleaning jobs even easier. 

All of the above sounded like music to my ears as after a winter and spring of lots of rain and muddy weather my patio was in desperate need of a deep clean this year before summer finally arrived. Although I've used a pressure washer before, this is the first one I've used for any length of time and I was keen to see if attacking the dirt and grime with a pressure washer really would make a difference to my outdoor space.

First impressions of the Bosch Universal Aquatak 135 pressure washer

The pressure washer comes in a relatively compact box, which was light enough for me to carry through to the garden on my own. It was easy to lift it out of the box using the sturdy handle at the top of the pressure washer. The wheels were already attached so I could simply stand it on the floor, unpack the rest of the box and start reading the manual - always my least favourite part of using garden tools! 

The pressure washer feels quite sturdy and the big, chunky handle and large wheels certainly makes it easy to manoeuvre it to where you want it on your patio. 

Getting started

Much to my husband's annoyance, I tend to be a little gung-ho about reading instructions and prefer to just get on with the job as quickly as possible, which typically ends up with me getting stuck 10 minutes down the line and having to start all over again, usually with his help. 

On this occasion, however, I was pleasantly surprised to find that there was very little to assemble as the main body of the pressure washer is already complete.

The manual comes with simple instructions that are really easy to follow. A series of diagrams illustrates how to adjust the handle, attach the lance, high pressure hose, water supply hose and the detergent attachment if you are using it (more on that later).

Within a few minutes I'd gone through the instructions and fitted the attachments. I already had the garden hose ready and attached to the outside tap too, so it was simply a case of hooking it up to the fully assembled pressure washer, turning on the tap and I was ready for some cleaning action. 

It's worth noting that you can also use the Bosch Universal Aquatak 135 pressure washer with water fed from a water butt or tank, so you don't necessarily need to have an outside tap. 

What is the Bosch Universal Aquatak 135 pressure washer like to use?

Once you've assembled the Bosch Universal Aquatak 135 pressure washer, you need to make sure that it's on level ground to ensure that it works correctly. Placing it on a paved area such as your patio, rather than on the lawn at the edge of the patio is the best option. 

It's easy to move the pressure washer to where you need it by lifting it using the large handle on top of the machine. It has large wheels so you can also pull it along. The handle is extendable for complete ease of use, so even if you're tall like I am, it's easy to reach down for the handle and pull it along behind you. Don't try and pull it by the hose as you could risk damaging the attachment, plus it could topple over and damage the main body of the machine.

Cleaning the patio pavers and pathway  

I'll be upfront here and say that our patio has certainly seen better days! It's on the list to be replaced when we extend our house in the coming months, so the pavers are quite old and we haven't been the best at keeping on top of cleaning them. The paving is a chequerboard design of alternating red and yellow-toned slabs so having them covered with a slight layer of dirt actually helps to mask this awful colour combination! In the past we've used the good old-fashioned method of scrubbing the patio with a broom and water to give it a refresh after winter. 

That being said, this spring they were in a particularly bad state after a very wet and muddy winter where the garden and patio often resembled a paddling pool rather than a welcoming spot to sit outside. The weather had taken its toll on the paving slabs and the patio and garden path were in serious need of a good clean. 

If yours is in a similar state, our guide on how to clean a patio has lots of useful tips to help you get it looking great again. 

Thanks to the Bosch Universal Aquatak 135 pressure washer's 3-in-1 nozzle, you can take your pick from three different settings. Choose from the fan, rotary, and pencil jet settings, depending on the task in hand. The manual has illustrations to show you what setting you should use for different surfaces.

To get started on the patio, I used the rotary setting as advised in the manual as this is best for removing dirt on patios. I worked my way across the patio to do a general clean of the entire space before I tackled any problem areas.
