The WD 3500 P came as a replacement device into the house after the old A was torched in 2504 because of a mishap from me. I use the vacuum cleaner in my amateur carpenter's workshop and am using the device completely zufrieden.Im compared to the old device of WD3500 P is much quieter, has with good 4 meters is twice as long suction hose and has an additional Gerätetsteckdose (beslastbar to 2200 Watt ), which thus enabled automatic switch can be started as soon as the connected equipment (drill, sander, jig saw, circular saw, router bits, electric planer etc) is turned on the vacuum cleaner. After switching off the vacuum runs on for about 3 seconds to empty the tube completely. I have the sucker now in the process sucked more than 2 months in operation, have a relatively large amount of wood dust and sawdust. The filter bag has still space for another month and the filter cartridge indicates the slats even no lining. That was when the devices from the "A" class was very different.
I mention möcte nor the additional blowing function of the vacuum cleaner via an additional Schlauchanschluss.Die combination of 6 m electric cable and 4 meter hose allows speedy work (I have thus freed about 250 m² paved area within 30 minutes from the leaves. This work is much more pleasant than with a classic leaf blower.
For yourselfers, I recommend buying the "Absaugsets for electrical appliances", also from Kärcher. Because of the extreme flexibility of the hose interfere with the use of electrical appliances in any way.
