🎯 Best for
Where the Karcher HD 5/11 earns its keep.
Patios & paving — dirt, algae and moss removal across stone, concrete and slab.
Driveways & paths — routine cleaning and pre-sale presentation work.
Property maintenance — between tenancies, before viewings, end-of-season tidy-ups.
Trade / refurb exteriors — shopfronts, forecourts, entrance areas where mains power is available.
Vehicle & equipment washdown — fleet vans, plant and tools (use wider spray patterns).
Pre-sale / end-of-tenancy — exterior tidy-up that lifts kerb appeal quickly.
⚠️ Not ideal for
Be honest about where pressure washing is the wrong tool — these jobs need a different approach.
- Delicate painted surfaces — high pressure can lift paint.
- Crumbling mortar or loose pointing — water and pressure can wash material out of the joint.
- Damaged render — risk of further chipping and water ingress.
- Heritage masonry — speak to a specialist before pressure washing.
- Indoor cleaning — pressure washers are for outdoor hard surfaces only.
- Sites without a 13A mains socket — choose the petrol pressure washer instead.
- Heavy oil and grease — cold water has limits and may not fully remove staining.
- Surfaces where pressure washing isn’t advised by the manufacturer or a surveyor.

| Surface | Suitability | Notes |

| Block paving | Generally suitable | Wider spray angle; re-sand joints after cleaning. |
| Tarmac | Use with care | Older or worn tarmac can shed material under pressure. |

🔌 Before you book — power & water checklist
Power
- Standard UK 230V / 13A mains socket within reach.
- 5 m mains cable on the machine — plan extension routing safely.
- Use an RCD rated for outdoor use.
Water
- An accessible cold-water tap or feed (max feed temperature 60°C).
- A garden / supply hose long enough to reach the unit.
- Drainage planning so run-off doesn’t pool or cross neighbouring property.
Confirm any required accessories before hire.
🛡️ Safety checklist
Quick safety reminders before you start.
- 1Test on a small area before working over the full surface.
- 2Keep the lance moving — never dwell in one spot.
- 3Avoid spraying directly at electrics, light fittings or sockets.
- 4Manage run-off so water and debris don’t flow into drains, neighbours or open ground.
- 5Avoid loose mortar, soft pointing and fragile render.
- 6Keep people, pets and bystanders well clear of the spray zone.
🚫 Common mistakes to avoid
-
Starting too close to the surface.
Begin with a wider spray pattern and a sensible distance — close in only if you need more concentrated power. -
Dwelling in one spot.
Holding the lance still creates streaks and can damage the surface — keep the spray moving. -
Using on delicate surfaces without testing.
Old pointing, soft stone and painted surfaces all need a test patch first. -
No drainage plan.
Without thinking about where the run-off goes, you can flood drains, neighbours or sensitive areas. -
Choosing a mains-powered unit when there’s no power.
If your site has no 13A socket, a petrol pressure washer is the right call.

❓ Frequently asked questions
Is the Karcher HD 5/11 good for patios?
Yes. With 110 bar working pressure and a 490 l/h flow rate, it’s a strong fit for most patio surfaces. Use a wider spray angle on softer or older stone, and always test a small area before working over the full patio.
Is it suitable for driveways?
Yes for routine driveway cleaning — block paving, slabbed driveways, concrete and paths all sit comfortably in its range. For very heavy, ingrained grime on commercial-grade driveways, the Heavy Duty 240V is the better step up.
Is it better than a domestic electric pressure washer?
For trade and serious property maintenance, yes. The Karcher HD 5/11 is a professional unit with a more capable pump and faster flow rate than typical DIY washers, so it gets exterior cleaning done quicker and copes better with regular use.
Do I need mains power?
Yes. The HD 5/11 is a 230V machine that plugs into a standard UK 13A socket. If you have no mains supply on site, choose the petrol pressure washer instead.
Do I need a water supply?
Yes — a standard cold-water tap or feed and a hose to connect it to the unit. The HD 5/11 accepts a feed temperature up to 60°C (do not exceed). Confirm any required accessories before hire.
Is it cold water or hot water?
Cold water. The HD 5/11 does not heat water itself. Cold-water pressure washing is ideal for general exterior cleaning but isn’t a replacement for hot-water units when you need to lift heavy oil, grease or industrial residue.
Can I use it for trade work?
Yes — that’s its sweet spot. The HD 5/11 is a Karcher professional unit built for regular trade use without stepping up to a heavy-duty industrial machine. Property maintenance, lettings turnaround, shopfront cleaning and trade exterior work are all comfortable jobs for it.
Can I use it on brickwork?
Use with care. Brickwork can usually be cleaned with the HD 5/11, but check pointing and mortar condition first — if anything is loose, soft or crumbling, pressure washing can wash material out of the joints. Use a wider spray angle and greater distance, and call us if in doubt.
Can I use it on render?
Call first. Render condition varies enormously. Modern, sound render in good condition can sometimes be cleaned at low pressure — but older, damaged or already-cracked render should be assessed by a specialist before using a pressure washer on it.
Can I use it on decking?
Use with care. Timber decking can be pressure washed, but use a wider spray pattern at a sensible distance and clean along the grain rather than across it. Test on an inconspicuous board first to check the wood’s reaction.
What if there is no mains power on site?
Choose the petrol pressure washer instead. The HD 5/11 needs a 230V / 13A mains supply — without it, a petrol unit is the right answer.
Can I collect from Greenford?
Yes. Hireload’s depot is in Greenford UB6 (West London) — collection is available during opening hours at booking. Bring your booking reference and ID.
Do you deliver in London?
Yes — London delivery is available by booking, with scheduled delivery and collection slots. Standard delivery is kerbside (the nearest safe vehicle drop-off point). Let us know at booking if you need help moving the unit inside or upstairs.
How do I choose between Electric, Karcher HD 5/11, Heavy Duty and Petrol?
Pick by job: Electric 240V for light domestic patio work, Karcher HD 5/11 for regular professional patio / driveway / brickwork cleaning, Heavy Duty 240V for tougher driveways and refurb work, and Petrol 2450 PSI when there’s no mains power. The comparison tables above lay it out side-by-side.
