High efficiency, trolley mounted wet & dry vacuum unit, equipped with an integrated discharging pump for continuous suction/dumping. Model equipped with the Ultra FilteRing System (UFS) that, thanks to its special polypropylene spacer polring, allows to keep the cartridge filter (M filtration class) always installed guaranteeing best suction performances and maximum motor protection (even in case of incorrect use by the operator). UFS is also a practical solution: the floating system is independent from the motor head, making cleaning and maintenance quick, simple and intuitive. This unique machine’s performances are very suitable for civil/emergency service, contract cleaners and fire brigades. It can be used also as a normal dry or wet & dry vacuum cleaner.
