Kärcher’s BR 30/4 C scrubber dryer eliminates the hassle and safety risks associated with floor mopping in public areas. As easy to use as an upright vacuum cleaner, the 30/4 thoroughly cleans and dries floors in a single pass, and can also be used for deep cleaning. Using a BR 30/4 C is faster, easier, more hygienic and safer for operators and public than mopping, leaving floors instantly clean, safe and usable. The BR 30/4 C is designed to be safe and hygienic for operators. Its four litre clean and dirty water tanks are fully removable and easy to clean and refill, while the roller brush and squeegees can be removed and replaced without tools.

BR 30/4 C is rated 3.3 out of 5 by 4.
Rated 2 out of 5 by from Doesn't perform as advertised 12 months usage including heavy winter dirt suggest this machine is fine over perfectly flat surfaces without joints. Despite using deeper rollers for tiling it will not clean the grouted joints properly, which remain dirty and hence insanitary. These joints are only 1mm deep at the most. Also it is essential to vacuum the floor thoroughly first because it will NOT pick up bits, fluff,or animal hairs, nor will it get into corners or up to skirting boards where germs and grime collect, so you need a hand scrubbing brush for a thorough deep clean. Karcher cannot supply the answer and basically remain uninterested. In purchasing Iwas swayed by the claims for this product, and it has been an expensive mistake. It is not fit for the purposes held out. A pity.

Rated 5 out of 5 by from Love it I've been using these for two years now. Wouldn't be without one! In fact I have three of them now that I leave at different contracts. If the machine is looked after and cleaned properly between use you should get good results. I recommend replacing the blue blades that come with it to the grey oil resistant ones as they are more hard wearing and last longer. Also, I tend to find the white roller brush better than the red one that comes with it for certain floor surfaces. I very rarely use manual mops unless I really have to as the results from this are far superior and the floor is left almost dry so is safer for slip hazards.

Rated 5 out of 5 by from Perfect - easy to use, gets in to small gaps! We have this and a BR40/10c. This is ideal for going underneath divides/panels where the other machine can't get. Simple to use. Lightweight. Don't understand the other review, can't have been using it correct. Keep the squeegee bars clean of hair/fluff. It's much better than using a mop.

Rated 1 out of 5 by from not very good I've had it for a year or so and it's never worked well. It leaves water behind and is slow to clean effectively. The heavy soil clean idea without the suction generates masses of water on the surface and when the vacuum is then used it pulls a grimy trail with it. Karcher advised an improved roller would improve function. It added cost but did not. Terrible value for money.
