Karcher Patio Cleaner T 5
Best OverallPros
- Gentle bristles safe for wood and rattan
- No splashback design
- Easy to attach to Karcher pressure washers
Cons
- Only compatible with Karcher machines
- Not suitable for large patio slabs
The Karcher Patio Cleaner T 5 is a dedicated rotary brush attachment designed to clean garden furniture without the aggressive spray of a standard pressure washer nozzle. Owner reviews consistently highlight how it lifts dirt from woven rattan and wooden slats without splintering or damaging the surface. The 9.8-inch cleaning width covers table tops and chair seats efficiently.
It connects to any Karcher K2 to K7 pressure washer via the quick-connect system. The brush rotates using the water jet, so there is no motor or battery required. Many users report that it reduces cleaning time by half compared to scrubbing by hand, and the low-pressure action means you can safely clean painted or varnished furniture.
Wet & Forget Moss Mould Algae & Dirt Remover
Best Budget LiquidPros
- No scrubbing or pressure washer needed
- Biodegradable formula
- Works on moss and algae
Cons
- Takes days to show results
- Not effective on heavy grease
Wet & Forget is a no-scrub outdoor cleaner that you apply with a garden hose sprayer. It uses a bleach-free active ingredient that kills moss, mould, and algae at the root. Owner reviews on Amazon note that it works best on plastic and metal furniture, and it is safe for nearby plants once dry.
The main trade-off is speed. It can take 5 to 7 days for the dirt to fully wash away with rain or a hose. For light soiling on a full garden set, this is the most convenient option. It is also one of the cheapest ways to clean multiple chairs and tables without buying a pressure washer attachment.
Nilfisk Patio Cleaner
Best Pressure Washer AttachmentPros
- Large cleaning path for tables
- Anti-splash guard
- Durable plastic housing
Cons
- Heavier than Karcher T 5
- Only fits Nilfisk pressure washers
The Nilfisk Patio Cleaner is a flat surface cleaner that works on horizontal furniture surfaces like table tops and bench seats. It uses two rotating high-pressure jets inside a shroud to blast dirt away without splashing. Owner reviews praise its build quality and the 12-inch cleaning width, which covers a standard table top in fewer passes than smaller attachments.
It connects to Nilfisk C and E series pressure washers. The unit has wheels that allow smooth gliding over flat surfaces. Some users note that it is less effective on curved or woven rattan furniture, but for solid wood and plastic tables, it delivers a deep clean quickly.
Bosch EasyAquatak Patio Cleaner Attachment
Best Light DutyPros
- Very lightweight
- Integrated soap dispenser
- Good for small furniture
Cons
- Only for Bosch EasyAquatak
- Small cleaning width
The Bosch EasyAquatak Patio Cleaner Attachment is a lightweight brush designed for the Bosch EasyAquatak range of low-pressure cleaners. It features an integrated soap reservoir that lets you apply cleaning solution directly onto the furniture. Owner reviews appreciate how easy it is to handle for chairs and small tables.
The 8-inch brush head is smaller than dedicated patio cleaners, so it takes longer for large surfaces. However, the gentle bristles are safe for painted and varnished wood. This attachment is best for occasional cleaning of a single garden set rather than heavy-duty use.
Stihl RE 80 Pressure Washer with Integrated Brush
Best Compact PowerPros
- Integrated brush for gentle cleaning
- Compact and portable
- Stihl brand reliability
Cons
- Expensive for occasional use
- Brush is small for large tables
The Stihl RE 80 is a compact electric pressure washer that comes with a dedicated furniture brush. It delivers 110 bar of pressure, which is enough to remove stubborn dirt, but the brush attachment keeps the force gentle on wood and plastic. Owner reviews highlight the build quality and the easy storage design.
The brush attachment is integrated into the unit, so there is no separate purchase needed. It is ideal for those who want a complete cleaning solution in one box. The main downside is the price, which is higher than buying a separate attachment for an existing pressure washer.
What to Check Before Buying a Patio Cleaner for Garden Furniture
Material Safety. Wood, rattan, and plastic require different cleaning methods. High-pressure jets can splinter wood or crack plastic. Look for rotary brush attachments or low-PSI liquid cleaners that are labelled safe for your furniture material.
Compatibility. Many patio cleaners are designed to work with specific pressure washer brands. Karcher attachments only fit Karcher machines, Nilfisk only fits Nilfisk. Check the connection type before buying. Liquid cleaners like Wet & Forget work with any garden hose.
Cleaning Width. A wider brush head cleans faster. For large tables, a 10-inch or 12-inch head is efficient. For chairs with intricate webbing, a smaller brush gives better control.
Chemical vs Mechanical. Mechanical cleaners (brushes, rotary heads) use water pressure to scrub. Chemical cleaners use active ingredients to break down dirt. Mechanical is faster for heavy grime; chemical is safer for delicate surfaces and requires less effort.
Mistakes to Avoid
Using a standard pressure washer nozzle on furniture. The concentrated jet can strip paint, gouge wood, and crack plastic. Always use a dedicated brush or a low-pressure setting.
Applying bleach-based cleaners. Bleach can discolour wood and damage the finish on rattan. Use oxygen-based or biodegradable cleaners that are safe for outdoor furniture.
Forgetting to test on a small area. Before cleaning the entire set, test the cleaner on an inconspicuous spot to check for colour fading or surface damage.
FAQs

Yes, but only with a low-pressure brush attachment like the Karcher T 5. A direct jet can splinter the wood.

Do patio cleaners work on plastic furniture?
Yes, rotary brushes and liquid cleaners are safe for plastic. Avoid abrasive pads that can scratch the surface.
How often should I clean garden furniture?
Once at the start of the season and once before storage is enough. Heavy soiling may require a mid-season clean.
