How I Cleaned My Entire Patio in 40 Minutes (Instead of Half a Day)

By Rob Calder — DIY enthusiast, weekend gardener, and someone who spent three years cleaning his patio the hard way before discovering there was a better one.

The Annual Patio Problem

Every spring, the same job. The patio behind my house is about 30 square metres of sandstone flags that spend the winter accumulating moss, algae, general grime, and the particular grey film that British weather deposits on everything left outside. By March it looks like it belongs to a different, grimier house than the one I think I live in.

I have a pressure washer — a decent Nilfisk machine that I've had for four years. For the first three of those years I cleaned the patio with the standard lance and a fan nozzle. It worked, eventually, but it was slow, physically tiring, and left streaky lines where the spray overlapped unevenly. A full patio clean took the better part of a Saturday afternoon — four to five hours of bent-over, arm-aching work that left me too tired to enjoy the clean patio I'd just created.

A neighbour mentioned he'd bought a patio cleaner attachment for his pressure washer and it had changed the job completely. I looked up the Nilfisk Power Patio Cleaner, saw it was compatible with my machine, and ordered it the same day.

Why the Nilfisk Patio Cleaner

The specification was exactly what I needed. The Nilfisk Power Patio Cleaner has a 28cm spray arm that rotates inside an enclosed housing, cleaning 6 times faster than a conventional nozzle. The enclosed housing is the key detail — it contains the spray, which means no streaking, no overspray soaking your legs, and a consistent, even clean across the entire surface. It includes both an easy-fit dirt blaster nozzle for heavy grime and a standard nozzle for more delicate surfaces like wooden decking.

Nilfisk compatibility was confirmed for my machine. The easy-fit connection meant no adapters, no fiddling, just attach and go.

The First Use

I attached it to the pressure washer in about thirty seconds. The connection is exactly as described — easy-fit, secure, no tools required. I started on the most heavily mossy section of the patio, the corner that gets the least sun and accumulates the worst growth.

The difference was immediate and dramatic. The rotating spray arm covered the surface evenly and completely, lifting moss and grime in a single pass in a way the lance had never managed. The enclosed housing meant the spray went down onto the surface rather than out to the sides — I stayed dry, the surrounding area stayed dry, and the clean line was sharp and consistent.

I cleaned the entire 30 square metres of patio in 40 minutes. Forty minutes. The same job had taken me four to five hours with the lance. I stood at the end of it, slightly stunned, looking at a patio that was cleaner than it had been in years, having barely broken a sweat.

A Year of Using It

The time saving is transformative. I've used it three times since the first clean — a mid-summer refresh, an autumn clean before the leaves came down, and the spring clean this year. Each time, 30-40 minutes for the full patio. The job that used to consume a Saturday afternoon is now a quick morning task that leaves the rest of the day free.

The finish is better than the lance. No streaking, no uneven patches, no lines where the spray overlapped. The rotating arm covers the surface completely and evenly, and the result looks professionally cleaned rather than DIY-washed. My sandstone flags look better than they ever did with the lance.

The dirt blaster nozzle handles heavy grime. The corner that accumulates the worst moss gets the dirt blaster nozzle treatment first, then the standard nozzle for the finish. Having both options in the box means I can match the nozzle to the surface and the level of grime without additional purchases.

It works on multiple surfaces. I've used it on the patio flags, the concrete path down the side of the house, and the wooden decking at the back. The standard nozzle is gentle enough for the decking without damaging the wood. One attachment, three surfaces, all cleaned properly.

The Difference It Made

Outdoor maintenance is no longer something I dread. The patio clean used to be the job I put off for as long as possible because of how long and tiring it was. Now it's a quick task I do regularly because it's easy and the result is immediately satisfying. The garden looks better because I maintain it more often. That's the downstream effect of making a job genuinely manageable.

I've recommended it to three people with pressure washers. All three have bought it. All three have reported the same reaction: why didn't I do this sooner?

Would I Recommend It?

To anyone with a compatible pressure washer who has been cleaning large outdoor surfaces with a lance: yes, without hesitation. The time saving alone justifies the purchase many times over. The better finish is a bonus. Buy it before the next clean. You'll wonder what took you so long.
