An excellent choice if you want a thorough clean patio. Go for the power - it's well worth spending the extra. Multiply the flow rate (litres per hour) by the pressure (bar) - the higher the number, the better the clean. The T300 saves a lot of dirt blast, however for best results use the blaster. 2 detergent bottles mean you don't have to refil so much. My concrete drive never looked so white; I now have bright paving slabs on my patio where before I had a dull brown grime; my Mum's conservatory is spotless, the K7.91MDB making light work of the algae on the roof in no time. Slight draw back is there is no where to store the hose nor power cord when not in use, however you soon get used to winding it around the washer afterwards. I'd recommend the K7.91MDB because its a powerful, reliable and reputable brand that really does clean.

I bought this model having been impressed by the recent favourable Amazon reviews of this particular model, as opposed to the model I orginally had in mind which was not well reviewed. It is very powerful and has been excellent in cleaning patios, stonework etc. The T300 accessory which comes with it is useful to prevent a lot of the "blowback" when cleaning a patio but does not quite get the results that the spray lance does. I would certainly recommend this model.

Does exactly what it says on the box. A powerful pressure hose ideal for home use where you need the extra power of the big motor. The extra tools provided are all useful and do a competent job within their specialised uses. At this price it is good value for a good product

Wow what a product! We were a little nervous spending so much money as we had hired pressure washers in the past which were no better than turning on a tap! Read more

Well worth the extra money
Prior to this I had a cheap pressure washer from a large DIY chain. It was ok, but nothing wonderful.
