Cleaning up building sites and industrial workplaces is going to be made easier by a light but powerful vacuum cleaner which runs off an ordinary 230-V single-phase socket. The PVL 2800 from Pullman Scandinavian AB weighs only 40 kg, but still packs 2.8 kW suction power.  It’s also quiet, with a noise level of only 69 dB(A), which means it can be used without ear-defenders.
