Heavy - yes! But there is a tank for 5 liters of water, and with it I have my 2-room apartment with a balcony on the 1st tank. I also changed the rubber bands on the joints after 4 years (began to leak), I didn’t find my relatives, I picked up similar ones on the market for a penny. After 5 years, the engine smoked and sparkled, but I suppose that it was my fault that I removed construction dust (I bought a donor with a broken tank and a full set of nozzles and pipes for 3on ebay and now I have a vacuum cleaner with 2 sets of consumables From time to time I sometimes lubricate the pipe connections with oil, and everything is easily inserted. Of the minuses - every time after cleaning I spend 20-25 minutes washing the pipes, nozzles and tanks after use. You can not do this, but then everything will dry . The choice is yours))
