Bosch UniversalAquatak 36V-90
Best OverallPros
- Highest PSI in Bosch cordless range
- Dual battery system for extended runtime
- Includes foam nozzle and brush
Cons
- Requires two batteries (higher cost)
- Heavier than single-battery models
The Bosch UniversalAquatak 36V-90 is the most powerful cordless pressure washer Bosch offers, delivering 1305 PSI that rivals some entry-level corded units. It uses two 18V batteries in series to achieve this pressure, making it suitable for cleaning patios, driveways, and stubborn garden dirt. Owner reviews consistently praise its cleaning ability and the convenience of not needing a power outlet.
Aggregated feedback from UK retailers shows high satisfaction with the build quality and the included accessories like the adjustable lance and soft brush. The main drawback is the need for two batteries, which increases the upfront cost if you don't already own Bosch 18V tools. However, for users invested in the Bosch Power for All system, this is the clear top choice for heavy-duty cordless cleaning.
Bosch EasyAquatak 120
Best Value / Light CleaningPros
- Lightweight and easy to carry
- Uses single 18V battery
- Great for car and bike cleaning
Cons
- Not powerful enough for heavy patio grime
- Shorter runtime on one battery
The Bosch EasyAquatak 120 is the most popular cordless model from Bosch, thanks to its balance of portability and adequate cleaning power. With 870 PSI, it handles light patio cleaning, garden furniture, and car washing with ease. Owner reviews highlight its quiet operation compared to petrol washers and the convenience of grabbing it from the shed without dragging a hose.
It uses a single 18V battery from the Bosch Power for All system, making it a cost-effective choice for those already in the ecosystem. The included adjustable nozzle and dirt blaster add versatility. Some users note that for very dirty patios, you may need a second battery or a more powerful model, but for most domestic tasks, this is a solid performer.
Bosch AdvancedAquatak 18V-100
Best Mid-Range PowerPros
- Good balance of power and portability
- Includes high-pressure and low-pressure modes
- Compatible with Bosch 18V system
Cons
- Not as powerful as dual-battery models
- Some users report battery drain on max setting
The Bosch AdvancedAquatak 18V-100 sits between the entry-level EasyAquatak and the flagship 36V model, offering 1015 PSI from a single 18V battery. This makes it a strong contender for users who want more cleaning power than the 120 but without the complexity of dual batteries. It is effective on patios, driveways, and garden paths.
Owner reviews note that the adjustable pressure settings are useful for delicate tasks like cleaning windows or cars. The build quality is typical Bosch, with a sturdy plastic housing and comfortable handle. The main limitation is battery life; on the highest setting, a 4.0 Ah battery lasts around 15-20 minutes, so having a spare is recommended for larger jobs.
Bosch EasyAquatak 110
Best Budget / CompactPros
- Very lightweight and compact
- Lowest price in Bosch cordless range
- Easy to store in small spaces
Cons
- Limited cleaning power for tough grime
- Basic accessories included
The Bosch EasyAquatak 110 is the most affordable entry point into Bosch's cordless pressure washer lineup. With 798 PSI, it is best suited for light tasks like cleaning bikes, garden tools, and delicate patio furniture. Its compact size makes it easy to store in a shed or car boot.
Owner reviews appreciate its simplicity and low weight, making it accessible for users who may struggle with heavier machines. However, it is not designed for heavy-duty patio cleaning or removing ingrained dirt. For users on a tight budget or with very light cleaning needs, this is a practical choice that still benefits from Bosch's build quality.
Bosch UniversalAquatak 18V-100
Best VersatilityPros
- Versatile with multiple spray patterns
- Good power for single battery
- Includes detergent tank
Cons
- Similar specs to AdvancedAquatak
- Less common in UK stores
The Bosch UniversalAquatak 18V-100 offers similar performance to the AdvancedAquatak but with a focus on versatility through its adjustable lance and included accessories. It delivers 1015 PSI and features a built-in detergent tank for applying cleaning solutions. This makes it a good all-rounder for users who want to switch between pressure washing and chemical cleaning.
Owner reviews note that it handles a variety of tasks well, from car cleaning to patio maintenance. The main downside is that it overlaps significantly with the AdvancedAquatak, and availability can be patchy in some regions. For users who find it in stock, it is a capable and flexible cordless pressure washer.
What to check before buying a Bosch cordless pressure washer
Battery compatibility is the first consideration. All Bosch cordless pressure washers use the 18V Power for All battery system, shared with many Bosch home and garden tools. If you already own Bosch 18V tools, you can save money by buying a body-only model. Check the battery capacity you have; larger 4.0 Ah or 5.0 Ah batteries provide longer runtime than the standard 2.5 Ah packs.
Water supply is also important. While cordless pressure washers free you from mains power, they still need a water source. Most models can draw from a bucket or connect to a garden hose. For bucket use, ensure the model includes a suction hose and filter. The flow rate (L/min) determines how fast you can clean; higher flow rates are better for rinsing large areas.
Pressure output (PSI or bar) dictates cleaning power. For light tasks like car washing, 800-900 PSI is sufficient. For patios and driveways, aim for 1000 PSI or more. The dual-battery 36V-90 model offers the highest pressure, while single-battery models are more portable but less powerful.
Mistakes to avoid when choosing a Bosch cordless pressure washer
One common mistake is underestimating battery consumption. Pressure washers drain batteries quickly, especially on high-pressure settings. Always check the runtime estimates and consider buying an extra battery if you have large areas to clean. Another mistake is ignoring water quality; using dirty or sandy water can clog the nozzle and damage the pump.
Some buyers also overlook the importance of accessories. Models with adjustable lances, foam nozzles, and brushes offer more versatility. Avoid the cheapest model if you need to clean patios; the EasyAquatak 110 may struggle with stubborn dirt. Finally, check the warranty period. Bosch typically offers a 2-year warranty, but some retailers extend this. Register your product after purchase for full coverage.
