Few things are more satisfying than a pressure washer turning a grimy, green patio back to its original colour. It’s the outdoor equivalent of watching someone pop a blackhead on YouTube — deeply, irrationally satisfying.
I’ve owned a Bosch Aquatak and currently have a Kärcher K2. I’ve cut corners, made mistakes, and learned what actually matters when you’re buying a pressure washer for home use. This guide gives you the honest version.
💬 Estelle’s note: My Bosch Aquatak gave up after a couple of years — and I’ll be honest, I probably didn’t treat it gently. I now have a small Kärcher K2, which does the job perfectly for my needs. My garden isn’t massive and the patio is manageable, so the K2 is plenty. That said, if you have a larger driveway or patio, or you want something that’ll last longer, I’d look at upgrading. I learned that the hard way.
What to Look For — The Specs That Actually Matter
The box of every pressure washer is covered in numbers. Here’s what they actually mean for cleaning your patio:
- This is the ‘punching power’ — how hard the water hits the surface. For patios and driveways, you want at least 120 bar. 130–150 bar is the sweet spot for most home jobs. — Bar pressure
- This is how fast the machine rinses away the dirt it’s dislodged. A higher flow rate means faster cleaning. Don’t just look at bar pressure — it’s the combination of both that determines real-world performance. — Flow rate (litres per hour/minute)
- Longer is better. Anything over 6 metres means you can clean a whole patio without dragging the machine around constantly. — Hose length
- Heavier machines are more stable but harder to move. Look for decent wheels if you’re buying a larger model. — Weight and wheels
- A patio cleaner attachment is worth its weight in gold for large areas — it cleans evenly and stops dirty water spraying on your walls. A vario lance (adjustable spray) is standard on most machines. — Included accessories
For most home use — patio, car, garden furniture — anything in the 120–140 bar range is ideal. More pressure than that risks damaging softer surfaces like wood or pointing.
Our Top Picks
🥇 Best Overall — Bosch Universal Aquatak 135
💰 Price: ~£150–£185 | Corded | 135 bar | 1,700W
The Bosch Universal Aquatak 135 consistently tops tested reviews from BBC Gardeners’ World and other independent testers — and it deserves the reputation. At 135 bar it has enough power to lift years of algae from textured paving, while being light enough to carry around the garden without a trolley.
It comes with a detergent bottle, two nozzles (turbo and vario), and the steel-reinforced hose holds up well in use. The Aquatak also has dedicated storage for all its accessories on the body of the machine, which sounds like a small thing but saves an enormous amount of time.
The operating pressure is smooth and controllable — ideal for switching between cleaning the patio aggressively and the car more gently without swapping nozzles constantly.
Best for: Most homeowners who want a reliable, versatile machine at a fair price.
- ✅ Excellent cleaning performance at 135 bar
- ✅ Lightweight and easy to carry
- ✅ Steel-reinforced hose
- ✅ Dedicated accessory storage on body
- ✅ Top-rated by BBC Gardeners’ World
- ❌ No wheels — harder to move around larger areas
- ❌ Nozzles can be stiff to fit/remove
🥈 Best Budget Pick — Kärcher K2 Power Control
💰 Price: ~£80–£110 | Corded | 110 bar | 1,400W
This is what I use — and for a small-to-medium patio and occasional car wash, it’s genuinely all you need. The K2 is compact, easy to store, and the Kärcher name means you’re getting a machine built by people who have been making pressure washers since 1950.
The Power Control version has a variable pressure dial on the gun — useful for switching between 20 bar (gentle car wash) and 110 bar (proper patio cleaning) without changing nozzles. It comes with a vario lance and a dirt blaster nozzle.
The hose is 4 metres, which is the one limitation — for a larger patio you’ll find yourself moving the machine more than you’d like. But for typical UK back gardens, it’s perfectly adequate.
💬 Estelle’s note: The K2 has been solid for me — no complaints. The one thing I’d say is that if your patio is large or you’re doing the driveway as well, the 110 bar is working hard and you’ll benefit from stepping up to a K3 or K4. For my garden it’s perfect.
Best for: Small gardens and occasional use. A reliable, no-fuss machine at a great price.
- ✅ Reliable Kärcher quality at entry-level price
- ✅ Variable pressure control on gun
- ✅ Compact and easy to store
- ✅ Comes with two nozzles
- ❌ 110 bar is on the lower end for stubborn patio grime
- ❌ 4m hose is short for larger areas
- ❌ Hose can kink in cold weather
🥉 Best Mid-Range — Nilfisk Core 140
💰 Price: ~£160–£190 | Corded | 140 bar | 1,800W
The Nilfisk Core 140 is the machine for people who want proper cleaning power without going to the very top of the market. At 140 bar with a strong flow rate, it handles even stubbornly algae-covered paving with ease — and the PowerControl dial on the lance makes it simple to adjust pressure for different surfaces.
The built-in hose reel is a standout feature — no tangles, no fighting with the hose as you move around. Combined with the 8-metre hose, you can cover a good-sized patio without moving the machine at all.
Best for: Homeowners with larger patios or driveways who want a powerful, well-built machine.
- ✅ 140 bar with strong flow rate
- ✅ Built-in hose reel — no tangles
- ✅ 8-metre hose for excellent reach
- ✅ PowerControl dial for easy pressure adjustment
- ❌ More expensive than Bosch or Kärcher
- ❌ Heavier than the Bosch Aquatak
⭐ Best Cordless — Stihl REA 60 Plus
💰 Price: ~£250–£320 | Cordless | Battery powered
Cordless pressure washers have improved dramatically in recent years, and the Stihl REA 60 Plus is the standout model. It delivers pressure levels comparable to corded machines, packs away neatly with an integrated hose reel, and gives you the freedom to use it anywhere — no extension lead required.
For anyone who wants to clean an outbuilding, a boat or areas far from sockets, this is genuinely game-changing. The power dial allows you to adjust jet strength, and the battery life is impressive for a cordless washer.
Best for: Anyone who needs maximum freedom of movement, or who wants to clean areas without access to a power socket.
- ✅ Cordless freedom — use anywhere
- ✅ Pressure rivals corded models
- ✅ Neat integrated storage
- ✅ Power dial for adjustable pressure
- ❌ Higher price point
- ❌ Battery runtime limits very large jobs
💡 Best for Cars — Kärcher K3 Power Control
💰 Price: ~£120–£150 | Corded | 120 bar | 1,600W
If you’re splitting use between the patio and the car, the K3 hits the sweet spot. The 120 bar pressure is more than enough for both tasks, and the 6-metre hose gives you room to move around the car comfortably. The K3 Home version comes with a patio cleaner attachment included — excellent value.
Best for: People who want one machine for both car washing and patio cleaning.
- ✅ 120 bar suitable for both patio and car
- ✅ 6-metre hose — good reach
- ✅ K3 Home version includes patio cleaner
- ✅ Well-priced
- ❌ Not the most powerful for heavily soiled patios

Safety Tips
- Always wear safety glasses and closed-toe shoes when pressure washing.
- Start with the widest, lowest-pressure setting and increase as needed. You can always clean more but you can’t undo damage to soft stone or wood.
- Keep the nozzle moving — don’t hold in one spot on delicate surfaces.
- Never point a pressure washer at people, animals or plants.
- Cover outdoor electrical sockets before you start.
- Don’t use the turbo/dirt blaster nozzle on car paintwork — it’s too aggressive.
Frequently Asked Questions
How often should I pressure wash my patio?
Once or twice a year is usually enough for most UK patios — typically in spring before the outdoor season and in autumn after the leaves have come down.
Can I use a pressure washer on block paving?
Yes, but be careful not to blast out the sand between blocks. Use a medium-pressure fan nozzle rather than the turbo/pencil jet. Re-sand the joints with kiln-dried sand afterwards if needed.
Can I use a pressure washer to clean my car?
Yes — but use the lowest pressure setting and the widest fan nozzle, not the turbo/dirt blaster. Keep the lance at least 30cm from the paintwork.
Is a more expensive pressure washer worth it?
For occasional use (a couple of times a year), a mid-range machine like the Bosch Aquatak 135 is all you need. If you’re cleaning a large driveway regularly or want something that will last 10+ years, spending more is worth it.
My pressure washer keeps cutting out — what’s wrong?
This is usually caused by a kinked or restricted hose, a blocked nozzle, or the thermal cutout activating (some machines cut out when overheated). Check the hose first, then clear the nozzle with the cleaning needle if provided.
Final Verdict
For most UK homeowners with a standard patio and garden, the Bosch Universal Aquatak 135 is the best all-round choice — reliable, well-made, and powerful enough for everything you’ll throw at it.
If you’re on a tighter budget and your patio isn’t huge, the Kärcher K2 does a solid job (it’s what I use). And if you want the freedom of cordless, the Stihl REA 60 Plus is genuinely impressive for a battery-powered machine.
