The Bosch to buy for a UK home in 2026 is the UniversalAquatak 135. It is a tap-fed mains washer in the same useful 130 bar class as a Kärcher K4, lighter, and usually cheaper on the high street. This page is the brand hub: which Bosch to buy, then where to read the deep review.
It is not a lab test. Specs come from Bosch DIY. Street prices come from Wickes and Bosch DIY in August 2026.

Start with the job. Cars, furniture and a normal patio, and you will carry the machine up steps, is the UniversalAquatak 135. A long drive where you want to park the trolley once is usually a Kärcher, not a bigger Bosch. No outdoor tap is the Fontus, a cordless trolley with a tank, not a second mains washer.
Paint-safe settings sit on the cars page. The brand-agnostic mains shortlist is the electric pressure washer guide. The yellow range in full is the Kärcher hub. First-use setup and frost drain-down are on how to use a pressure washer.

Bosch UniversalAquatak 135
The best Bosch pressure washer for most UK homes
- Buy: Wickes £128 · Bosch DIY lists £184 · Tooled-Up has been around £164
- Part number: 06008A7C70
- Pressure: 135 bar max
- Flow: 7.5 L/min max (Bosch). Wickes quotes 410 L/h
- Hose: 7 m PVC
- Motor: 1.9 kW
- Weight: 7.9 kg without accessories
- In the box: gun, lance, 3-in-1 nozzle (fan, rotary, pencil), 450 ml high-pressure detergent bottle, water filter
- Who it is for: flats with a parking bay, smaller cars, and anyone who will carry the washer up steps rather than wheel a heavier trolley
This is the Bosch to buy if you have a garden tap and a 13A socket. 135 bar sits in the same useful home class as a K4. You get a metal three-cylinder pump and a machine you can actually lift. You give up the 8 m Flex hose and the gun that shows the pressure step.
Bosch puts the detergent in a 450 ml bottle on the lance, which is the honest way to soap a car if you do not want a separate foam cannon. Fan jet for paint. Rotary for stone. Pencil for the bits of the drive that are not a car. That trio is clearer than a dirt blaster that people leave clicked on by mistake.
The hose is a metre shorter than a K4 Flex and it is ordinary PVC. You will move the trolley more often around a large estate car. Push-fit connections and a quieter pump are the comfort extras. The pump spec is better than the Wickes ticket suggests.
Amazon has not always had a featured offer on this SKU. Wickes is the live UK price to start with. Bosch’s own £184 is what the official page asks, not what you should pay. Car-wash order sits on the cars page. How this machine sits against a K4 and a Nilfisk is on the electric guide.
Skip it if you want an 8 to 10 m hose and a gun that shows the pressure step. That is a K4 or K5 on the Kärcher hub. Skip it if you already own Kärcher lances and bottles and want to stay in that system. Skip it if the patio is the main job and you wanted a T 5 in the box. Bosch heads are a different clip. Skip it if there is no outdoor tap. That is the Fontus, below.
Sub-£150 mains boxes sit on the budget pressure washer page.
Bosch Fontus Gen II
The Bosch to buy only if there is no outdoor tap
- Buy: Amazon.co.uk (£179 bare, £198 kit with battery)
- Part numbers: kit 06008B6171, bare 06008B6102
- Pressure: 20 bar, low / medium / turbo
- Flow: about 1.5 to 3.1 L/min (90 to 186 L/h)
- Battery: 18V Power For All. Most street kits include a 2.5Ah pack and charger
- Water: 15 L built-in tank, or a garden tap. 4 m PVC hose
- Weight: 6.4 kg without battery on the Bosch DIY sheet. Wickes prints 9.43 kg for the unit they sell. Add 15 kg when the tank is full
- Who it is for: a house with no outdoor tap, a caravan, an allotment, or anyone who wants to fill once at the kitchen sink and roll the machine to the car
Do not buy this instead of the UniversalAquatak if you already have a tap and a socket. Twenty bar is a rinse, not a 135 bar wash. The Fontus exists because water is the missing thing, not as a substitute for the mains machine.
Fifteen litres is enough for bikes, furniture, boots and a careful rinse of a small car. It is not enough for a dirty family hatchback on one fill. Plan on a refill, or clip the inlet to a tap if one is there. A full tank is roughly 22 to 25 kg on the wheels. Drain it before the boot.
If you already own Power For All packs, buy the bare tool at £179. If you do not, the kit at around £198 is the complete buy. Bosch claims up to 60 minutes on the 2.5Ah pack. That is battery time, not tank time. At the higher flow the water is gone in well under ten minutes of trigger time.
The deep tank comparison, including the Kärcher OC 6-18 and the Makita case, sits on the cordless pressure washer with tank page. Read that before you spend Fontus money.
Skip it if you always have a tap and you want more punch. Buy the UniversalAquatak 135. Skip it if 6 litres for a bike is all you need. That is the smaller Fontus 18V-6, under what we left out.
Who it is for
A Bosch mains washer is for a UK house with a garden tap and an outdoor 13A socket, or a socket you can reach with a proper outdoor-rated lead. That pair still beats battery for a weekly family wash.
- Steps, a small bay, lowest named 135 bar class. UniversalAquatak 135.
- Cars, furniture and a normal patio, and you want the longer Flex hose. K4 Power Control Flex. See the Kärcher hub.
- No outdoor tap. Fontus Gen II. The tank page is the buy guide.
- No outdoor socket, but you do have a tap or a bucket. A handheld from the cordless set, not a Fontus and not a bigger Aquatak.
How to choose
Bosch or Kärcher
For a careful car wash and light stone, the UniversalAquatak 135 is in the same useful class as a K4. 135 bar and about 410 L/h will rinse foam. You give up the 8 m Flex hose, the pressure-step gun and the T 5 ecosystem. You gain about 4 kg less weight and a street price under £130 at Wickes.
Buy the Bosch if that trade is the point: you will carry it, the bay is small, and you do not already own yellow bottles. Buy the K4 if you want one machine for the house and you will walk around a family car without moving the trolley. Buy the K5 if the drive is long and green. Cars do not need 145 bar. They need hose and flow. That argument in full is on the electric page.
Mains or Fontus
Mains is the default. The UniversalAquatak needs a garden hose and a 13A socket. That pair is still the best Bosch set-up for a weekly wash. The Fontus is the workaround when the tap is missing, not a quieter Aquatak.
Twenty bar will rinse a car if you foam first. It will not strip a mossy patio the way a tap-fed 135 bar machine does. If the missing thing is a socket, not a tap, a siphon handheld is usually lighter and stronger than a 15 litre trolley. The tank page is honest about that.
Hose, nozzles and paint
Seven metres of PVC walks a small car if you park at a corner. It will not let you stand still on a long van. Move the trolley. Do not stretch the hose around a hot exhaust.
Use the fan jet on paint, at a distance. Leave the rotary and the pencil off lacquer, glass, sensors and tyres. The 450 ml bottle on the lance is enough shampoo for a hatchback if you foam first and rinse with purpose. First-use setup, nozzles and frost drain-down are on the how to use a pressure washer page.
What we left out
AdvancedAquatak as a pick. Bosch DIY UK lists a heavier AdvancedAquatak mains machine. Until there is a clear street price next to the UniversalAquatak 135, it is not a pick here.
Fontus 18V-6 Bike Cleaner. Official UK page, 6 litre tank, 20 bar, 4.4 kg. Bosch DIY lists the solo tool at £161.05. Street bare tools have sat around £130 to £143. It is a genuine tank, and it is the right size for a muddy bike. Six litres will not wash a car. It is not a household trolley.
FAQ
What is the best Bosch pressure washer in the UK right now?
The UniversalAquatak 135, if you have a tap and a socket. 135 bar, about 410 L/h, 7 m hose, 7.9 kg, and £128 at Wickes against a £184 list. Buy the Fontus Gen II only if the outdoor tap is missing. That is a 20 bar tank trolley, not a second mains washer.
Is a Bosch as good as a Kärcher?
For a careful car wash and light stone, yes. You give up the 8 m Flex hose, the pressure-step gun and the T 5 ecosystem. You gain weight and price. Buy the Bosch if that trade is the point. Buy the K4 if you want one machine for the house. The shortlist that puts both next to a Nilfisk is the electric guide.
Can I wash a car with a Bosch pressure washer?
Yes, on the fan jet, at a distance. Do not use the rotary or pencil tip on paint. The 450 ml bottle on the lance is the soap, not a reason to skip a mitt. Full order sits on the cars guide.
Should I buy the Fontus instead?
Only if there is no outdoor tap. The Fontus will not match the UniversalAquatak on a mossy patio or a weekly family wash. If that is your constraint, use the tank page. Do not stretch a 20 bar trolley into a driveway tool.
Will a Kärcher patio head fit a Bosch?
No. A T 5 or T 7 Plus clips onto a Kärcher Home & Garden gun. It will not clip onto a Bosch. If the patio head is the reason you were looking at yellow, stay on the Kärcher hub.
What if I have no outdoor socket?
A mains Aquatak will not invent one. If the missing thing is a tap, the Fontus is the Bosch answer. If the missing thing is a socket and you can still reach a tap or a bucket, a handheld is usually the better buy. Do not park a UniversalAquatak in the kitchen and run a lead through the hall.
