After six months of regular followup, finally I got a new model of vacuum cleaner, it is called Euroclean IQ .
It is much better compared to the previous one as it suits my needs.
It does not make noise, so no headache for me or neighbors.
It automatically senses the surface and adjusts power consumption accordingly that is - more power consumed for dirty surfaces and very little for clean ones.
Very to the point accessories and extremely easy to use.
4.Its filters are so good that I can actually feel the air quality of my room purified comparatively.
Body is lightweight so I just hold the hosepipe and it follows me around the house, running and hurrying on its wheels.
Attachments are lightweight and sturdy, that I am not exhausted after whole house cleaning and using it everyday.( actually when I cleaned my walls with its brush attachment for the first time, a guest thought we have had white wash done recently, because the whole house was glowing suddenly)
Its use has stopped my exposure to dust, dust mites and allergens so my allergic skin problem and breathing problem are finally getting cured. I am 70% healed now.
It has retractable wiring so after cleaning I just push the button and complete wire(about 12 meters long) comes back running and jumping and happily gets stored inside the unit.
It has thick dust bag which stores a lot of dust so don’t need to empty it regularly nor need to touch the dust and toxins by myself.and when needed I just give it to garbage collectors to empty it. And also there are extra dust bags given with this unit.
Final verdict:- problem solved and very happy with the new product though Eureka Forbes has to return Rs7000/- to me as euroclean IQ costs Rs 18000/- only but they have promised to send the remaining money and bills soon.
