Best Wall Mounted Pressure Washer UK 2026: G20, Essential and Plus Compared

Finding the best wall mounted pressure washer UK homeowners can choose depends on three main factors: the size of the cleaning area, the hose length required and the surfaces you clean most often.

Unlike a traditional portable jet wash, a wall mounted pressure washer stays installed in one place. Its high-pressure hose is stored on an integrated retractable reel, helping reduce floor clutter and removing the need to coil the hose manually after every use.

This makes the format particularly practical for UK garages, compact driveways, patios and private outdoor areas where storage space is limited.

In this guide, we compare the four Grandfalls configurations currently available:

• Grandfalls G20 with Ordinary Hose
• Grandfalls G20 with Ultra-Soft Hose
• Grandfalls Essential
• Grandfalls Plus

We look at pressure, flow rate, hose length, hose type, intended cleaning tasks and price to help you find the most suitable model for your home.

Quick answer: which Grandfalls model should you choose?

Best overall: Grandfalls Plus

Choose the Plus if you want a 30m retractable hose, 165 bar maximum pressure and a more flexible Ultra-Soft hose for mixed outdoor cleaning and regular car washing.

Best value: Grandfalls Essential

Choose the Essential if you want the same maximum pressure and 30m reach as the Plus at a lower price, and are comfortable using an Ordinary high-pressure hose.

Best compact option for car washing: G20 Ultra-Soft Hose

Choose this model if a 20m hose is enough for your property and you want a softer, more flexible hose that is easier to manoeuvre around a vehicle.

Best budget option: G20 Ordinary Hose

Choose the standard G20 if you mainly clean a car, small patio or compact driveway and want the lowest-priced option in the Grandfalls range.

Why wall mounted pressure washers suit UK homes

They save valuable floor space

Many terraced homes, semi-detached properties and single-car garages have limited storage space.

A portable pressure washer needs somewhere to sit, along with its hose, power cable and accessories. Even when the machine itself is relatively compact, the equipment can quickly occupy a garage corner or create clutter around a utility area.

A wall mounted system keeps the main unit off the floor and stores the high-pressure hose on an integrated reel. This creates a cleaner setup and leaves more space available for vehicles, tools and other outdoor equipment.

They reduce cleaning setup time

Traditional pressure washers usually need to be taken out of storage, moved into position and packed away after use.

With a wall mounted system, the main unit stays in place. You pull out the required length of hose, complete the cleaning task and allow the hose to retract when finished.

That makes it easier to handle routine jobs such as:

• Washing a car
• Cleaning patio slabs
• Rinsing garden furniture
• Removing dirt from block paving
• Cleaning paths and walkways
• Maintaining smaller driveways
• Washing exterior surfaces carefully

They make regular cleaning more convenient

The UK’s damp conditions can encourage moss, algae and green surface build-up on patios, paths, decking and shaded outdoor areas.

A permanently installed pressure washer reduces the effort required to begin cleaning. Instead of waiting for dirt to build up into a larger job, homeowners can deal with smaller areas more regularly.

Wall mounted vs portable pressure washers

Wall mounted and portable pressure washers solve different problems.

Choose a wall mounted pressure washer when:

• You regularly clean the same property
• You want to reduce garage floor clutter
• You prefer automatic hose storage
• You need a longer hose
• You do not want to move the machine during cleaning
• You have a suitable permanent installation location

Choose a portable pressure washer when:

• You need to move the machine between properties
• You cannot drill into the wall
• You rent your home and do not have installation permission
• You need to store the machine indoors after every use
• Portability is more important than automatic storage
• You need to use the machine in several locations

Portable pressure washers often have a lower initial price and do not require permanent installation. However, they usually need more floor storage and require the user to move both the unit and hose during cleaning.

A wall mounted pressure washer normally requires more planning at the installation stage, but it can provide a more organised and convenient setup for repeated cleaning at one property.

How to choose the best wall mounted pressure washer

1. Measure the required hose length

Hose length is one of the most important specifications.

A 20m hose may be enough for:

• A compact driveway
• A small patio
• A dedicated car-washing area
• A private outdoor space close to the installation point

A 30m hose may be more appropriate when:

• The driveway is longer
• Several outdoor areas need to be reached
• The machine is installed inside a garage
• The hose needs to travel around vehicles or corners
• The installation point is far from the cleaning area

Measure from the proposed mounting location to the furthest surface you plan to clean. Add extra length for moving around vehicles, furniture and obstacles.

2. Compare pressure and flow rate

Pressure and flow rate affect different parts of cleaning performance.

• Bar measures how forcefully the water reaches the surface.
• Litres per minute measure how much water the machine delivers.

Higher pressure can help loosen stubborn dirt. A stronger flow rate helps rinse loosened dirt away.

More pressure is not always better. Cars, timber, painted surfaces and softer stone require suitable nozzles, greater distance and careful technique.

3. Decide which hose type suits your routine

The main difference between several Grandfalls models is the hose.

An Ultra-Soft hose may be preferable when:

• You regularly wash cars
• You frequently move around obstacles
• You want easier hose handling
• The cleaning area requires repeated changes of direction

An Ordinary hose may be sufficient when:

• You mainly clean patios and paths
• The cleaning route is relatively direct
• Price is a higher priority
• You use the machine less frequently

4. Check the installation requirements

Before purchasing, confirm that the intended location has:

• A suitable solid wall
• Access to a cold-water supply
• An appropriate electrical connection
• Enough clearance around the unit
• Suitable drainage
• Enough space for the hose to pull out freely

Renters, leaseholders and residents of managed properties should obtain permission before drilling or installing permanent equipment.

Always follow the product installation instructions.

5. Consider winter conditions

A wall mounted pressure washer should not automatically be treated as suitable for unrestricted outdoor exposure throughout the year.

Protect the unit according to the product instructions and avoid allowing water to freeze inside the pump, hose or connectors.

Before freezing temperatures:

• Disconnect the water supply where required
• Drain remaining water from the system
• Follow the manufacturer’s winterisation guidance
• Use a suitable protective cover where recommended
• Store removable components appropriately

6. Take operating noise into account

The listed operating noise is:

• 95 dB for both G20 versions
• 90–93 dB for the Essential and Plus

These machines should not be described as silent.

When using a pressure washer near terraced or closely spaced homes, avoid cleaning early in the morning or late in the evening. Hearing protection may also be appropriate during longer sessions.

7. Check local water restrictions

Temporary Use Bans may restrict mains-fed pressure washer use for activities such as cleaning cars, paths and patios.

Rules can vary between water companies and regions. Check the restrictions that apply to your postcode before using the machine during dry periods.
