Rated 5 out of 5 by from A Great vacuum cleanerI have had this vacuum cleaner for over two years now and I have not had any problems with it, it has phenomenal suction power even when it is full of dust and fluff it's also very quiet even on the highest power setting. I would recommend it to anyone looking for a quality vacuum cleaner.

Rated 3 out of 5 by from Not happyI bought this vaccum because of the silent noise but the sucking power is poor after a few time use.

Rated 4 out of 5 by from Cable jammed!Only had this hoover a few weeks and I am really impressed with it until today - the retractable cable has jammed and I cannot pull it out much more than a few feet! Although it has not stopped me using the hoover I am unable to vacuum the stairs and after having checked I cannot see how I can access the cable to fix the problem.

Rated 4 out of 5 by from Great Hoover Pooley Made AttachmentsI Have had this Vacuum cleaner for 2 years.After having our second child, me and my wife decided to INVEST in a high standard vacuum cleaner. After doing some research we decided to go for the Bosch silence 2 because of the power and the energy consumption and the quietness of the hoover. The vacuum its self is great as long as you empty it regular and clean the filters often, but the attachments are really cheaply made and fall apart quickly. The main attachment I have replaced twice and now the metal tubing itself is broken. I have repaired it with black nasty and cable ties, but this means no other attachments are able to be used without me cutting black nasty off and cable ties off. This is a massive let down considering the cost of the product! I would assume the parts would last the life of the hoover!!

Rated 2 out of 5 by from PainI bought this last year as I needed a vacuum cleaner that was easier to use now I am ill. How wrong I was. The hose keeps falling out and is now taped up and the light goes off all the time. I've checked and cleaned all the filters. It only has light use yet the metal pipe has gone through the very cheap plastic utensils and I'm now worried it will scratch new flooring. Sounds great when you read it all on paper but the amount of people having the same issues sounds ominous. I get the feeling I've wasted money I simply can't afford.

Rated 1 out of 5 by from worstWe bought this vac a couple of years ago on the strength of the Bosch name. However it has turned out to be the worst vac we have ever had. it is cumbersome, unwieldly, it does not move around objects very well, the bottom length of the hose comes loose, meaning it loses suction and you can get a nip from the joint, the red light comes on and it stops working for no reason, finally it is a nightmare to empty and clean the filters, I won't mention trying to do stairs with it!!

Rated 5 out of 5 by from Much Better Should be called a VacuumI bought this in June and it wasn't very good, so once I had posted my original review, customer service commented and said there were things I could try but failed to mention what they were!! So after contacting customer service they sent an engineer out on the Thursday who took the machine away and on the Tuesday I received a replacement, we hadn't been informed this was happening and a week later I got a phone call to say they were replacing the vacuum!! This one is far better it vacuums things up even on the low setting, on the high setting it sucks up the carpet. Does what it says on the tin.
