The high pressure washer is a good product for light cleaning of your vehicle, paths and other items around the home. It will not clean off heavy dirt so if you go four wheel driving on the weekend and have caked on mud on your car do not expect this cleaner to take the dirt off easily. It does make up for the lack of pressure by being light and convenient with the ability to be run from a garden hose, bucket or even a plastic bottle with supplied fittings. It comes with the washer gun and barrel extension a point nozzle, spray nozzle, hose and several connections as shown in the photos. The batteries supplied are ok however they do not supply much current and get bogged down after around 5-10 minutes of operation. Checking the battery voltage with a meter shows that they are still over 18v but they are down on current and so the washer does not operate fully. So with two batteries I expect around 20 minutes of 50% duty cycle operation. I purchased the unit with two batteries as I have other Makita tools and the batteries are supposed to be compatible. I can confirm that the batteries can power Makita tools but not the sort that draw much current. For instance they power my Makita torch, portable soldering iron etc but not drills, saws etc. as they require more current than the batteries can supply. On the other hand the pressure washer will accept Makita 18v batteries and if you have 5 or 6Ah ones then they will power the washer for a longer time than those supplied with the unit. The batteries supplied with the unit cannot be charged via standard Makita charger (they have their own wall charger) as they lack balance checking inputs and will not fit in the Makita charger.
This is the 2nd one I bought. The battery lasts 10 minutes. Pressure about 20-25bar , marginal for cleaning very dirty. I saw the roto accessory, and an extension 30cm for the nozzle. I noticed a difference with the first in that in the new the screw connection points of the hose and the nozzle adapter are now plastic and not metal (see first pict) , I do not know anymore it is more durable. I reserve the right to add after a few uses.
