My bosch aquatak 100 went completely dead last week. It had hardly had an hour of use cumulatively in almost an year since I bought it. Checked the warranty and found it was just for 6 months. After a few choicest words for Robert Bosch and his grand father, I decided to open it.

There is a pressure switch which was the first suspect.

Sure enough it was stuck open. There is a small brass pin which actuates the switch. Pushed it down and put a tiny drop of oil to lubricate it. The picture was taken after pushing it down.

It works fine now. For now I did not open any plumbing fearing leaks. But if it happens again, I'll open it and spray silicon on the O-rings.

Thank you. Yesterday I could not see your pics, but today they are showing up. This is useful information to remember for the future.

My Aquatak failure is the spray trigger. It is mostly stuck open. I just live with it, as I'm not enthusiastic about taking it apart --- but probably some lubrication is all that is needed.

Thinking of buying a pressure washer myself. After going to countless threads, looks like Karcher is the most preferred brand. However this brand does not have any support centre in Goa (where i live), hence had to look for other options.
A shop in Panaji is quoting a price of @Rs.8.2k for Black and Decker entry level washer (not aware of the model). While going through some online shopping sites came across this, B&D PW1570TD for Rs. 8.5k.

Should i go for it?????

Default Re: Buying & Using a Pressure Washer

I live on the 14th floor of an apartment complex which does not have any convenient points where I can wash my bike. The 390 is notoriously easy to get filthy and I'm at my wit's end to find a solution to easily wash the bike apart from using multiple buckets of water which are inconvenient and don't provide satisfactory results since there is no pressure.

A couple of days ago, some chaps had come to my house to spray the liquid that kills bees on to a hive which had formed near my bedroom balcony. I noticed that the guy was using a non-electric, hand operated pump. He filled up water and then pumped the device a few times and got a decent spray to a distance of about 8 ft.

My questions are:

1. Can this device be used to wash a bike? Will it generate enough pressure to clean the hard to reach places?

2. If yes, where can I purchase it from?

MODS: My question is about an "analog" pressure washer but please move if this is the wrong thread.

I doubt that generates enough pressure to blow mud away. There are some petrol/diesel operated pressure washers that you can consider. There was a discussion many pages back...

Since you live in a 14 storeyed building you'll have very good pressure at the parking space. You can simply add pressure nozzles like this to a PVC pipe and that will be sufficient to generate ample pressure to wash your car/bike.

You can also buy this type pressure nozzle from aliexpress.com (better quality at lesser price). Try to find a all brass one.

The advantage with Karcher is that (it says on the pack), it saves 80% of water by releasing high pressure water droplets. I find it very effective on wheel wells.

Rest of the car is (Could be) taken care of by the watchman.

When you use such a device, the energy that is generated by the manual pumping mechanism is minuscule. At best, it can help generate maybe 3 Bars of pressure, and flowrate is not affected at all.
For cleaning vehicles effectively, you require atleast 80 to 90 Bars of pressure, and a flowrate over 5 Litres per minute is helpful too.
I've said this earlier as well, water pressure will define the effectiveness with which the spray will attack the mud/other items stuck to the surface, while flowrate will determine the SPEED with which the areas are cleaned. You need a combination of both. And that's possible on an optimum power consumption:effectiveness ratio by High Pressure Washers.

Again, the output pressure is generally 2 Bars, if its really good, and that will increase to about 4 Bars by these nozzles, while flowrate of 20 LPM, will reduce to about 15 LPM.
This will not make them as effective as you'd want, while still you will end up using more water everytime you wash the vehicle.

This fact is true, and applies to almost all high pressure washers. You can read my inputs on this here (Buying & Using a Pressure Washer).

The spray is sufficient to dislodge grit and grime say under the hood/bonnet. it can be used to spray soap but not powerful enough to "wash" the bike.

if money is not a constraint, but Karcher K3.550 which has bucket suction. it retails for around 17,000/-

WHen there is no way to use a pressure washer this type of nozzles are the best thing. Specially in a 14 stoereyed building which will have already sufficient water pressure at the basement. Use one and see. This may not not helpful in dislodging caked out mud but those can be taken care of by spraying some diluted shampoo and soaking a few minutes and then attacking with water spray.

The water nozzles are far better than the manual pressure pumps which the OP suggested.

BTW I do have a pressure washer - these are a nifty tool but where there is no power these are useless.

I agree with the fact that these can be used to spray the liquid soap solution. That will then need to be followed by manually scrubbing the surface with a microfiber sponge / cloth for effective cleaning of bird droppings/sticky things.
And then ofcourse the surface will have to be washed with plain water, to remove the dirt plus soap, and then dried.

I have not done this, but I remember this hint...

Carry some small bottles of carbonated (fizzy) water in the car. In case of bird droppings, open bottle, place thumb over opening and shake hard. Then squirt the bird dropping. (and the bird if it looks like it is going to do it again ).

I vaguely remember something about the fizzy water being alkaline, and therefore good to neutralise acids. Could this be true? Are bird droppings acidic? The certainly seem to be able to eat into surfaces.

Fizzy water or carbonated water is composed of water and carbon dioxide and is actually carbonic acid. So it won't help neutralise the uric acid in bird droppings. What would help is baking soda which is a base and mildly alkaline. Mix a small amount with water to form a watery paste and apply on the bird dropping. Wipe away after the dropping has softened.

I keep some QD solution in a Mr Muscle spray bottle. It has got a strong stream, sufficient enough to peel off the bird poo without having to scrape it off. I make it a point to take off the poo as soon as possible; every hour counts.
