A pressure-washer is my #1 gadget for giving your deck and garden a summer makeover — and right now Amazon has huge discounts on top models from Kärcher

Warmer days are here, and it's time to get your garden looking its best for the summer. If you have any kind of decking or paving, I can't overstate the difference a pressure washer can make.

I recently pressure-washed (and re-varnished) our deck at home, and it looks — genuinely — brand-new. It's a ritual I repeat at the start of every summer, and blasting all the winter dirt off is incredibly satisfying. Our sparking clean deck has drawn admiring comments from the neighbours, and the pressure washer is now making its way down our street as everyone gets in on the action.

Our pressure washer is a Kärcher model, and right now a whole load of Kärcher washers are seeing major discounts in the Home & Garden Week sale happening at Amazon UK(ends May 12). I've rounded up all the best offers below, including deals on compact, handheld washers that are perfect for smaller decks and homes that are lacking in storage space, as well as larger, more heavy-duty options if you have more square-footage to tackle.

It's worth paying attention to the attachments included with each pressure washer — look for an option with a larger, circular tool if you need to scrub wide areas.
