I didnt realise this was so common. Wish I had before we purchased a Bosch.
We weren't happy with the level of suction at first but thought that we had spent the money and if we looked after it it'll last us forever.
Within weeks of passing warranty we started seeing the red light.
Wasn't much better than a broom to start, now it's more of a scraper.
If this is so common surely there's a common solution, or should I be looking for a new vacuum?

This is the most expensive and the worst performing vacuum cleaner I have ever purchased. I paid over $700 for it and now avoid using it until my floors are really bad because it is so frustrating and difficult to use. The main issue I have is the sensor self cleaning light constantly comes on while the vacum is in use which means it constantly turns on and off. I have tried washing the filters but this doesn’t help & they are awkward to wash as repellent to water.

Was a great vacuum, until, like many others, I cant vacuum more than 3 meters without it overheating and going into self clean. Meticulously cleaned the vacuum since new. Obviously a design fault and Bosch don't want to know about a $850 vacuum that isn't even a year out of its miserly 2 year warranty.

I've just contacted Bosch regarding my machine and then read all the reviews here.
It seems the self-cleaning mode is the problem.
It cannot cope with a well kept house, 2 adults and a small dog.
Vacuum has become a time consuming and very stressful chore, as the machine stops every meter to clean itself and then stops all together.
It's been scrupulously maintained (cleaning, washing and drying filter), changed the HEPA filter and nothing seems to work.
I've come to the conclusion that this has been a big miss by Bosch, a lemon!

I had the problem with the self cleaning function from the day I purchased it. But when I complained at Harvey Norman they told me I have to clean the filter better. So I spent a long time cleaning it but it didn't help. Finally they accepted the failure and sent it away for repair as it was within the warranty. After I got it back it was working perfectly for maybe 2 months and then the same problem started again and it is even worse than before. The self cleaning goes off every 10-15 seconds. It is just terrible, I have 260 m2 to clean. I hate this vacuum cleaner. The warranty expired so I will probably throw it away soon. I would really expect much more from a Bosch product for $799.

Used it in a 3/1 house twice since buying it a couple of weeks ago. Now doesn't even do half of one room with out the sensor control flashing on 2 twice and then stays on red and powers down. Have cleaned the bag less container on each occasion and the filters are perfectly clean - only been used twice. Poor design/manufacture.

Very unhappy after purchasing this fairly expensive cleaner. It is easy to manouver, and has fantastic suction, however it works for about 45 second and then turns off for about 60 seconds, apparently to self clean, making it very frustrating to clean Even the smallest room. Had i realised this was going to be the case, i would not have purchased it

It constantly stops and has a filter error even though it's clean. I've had it for a year and can't wait to throw it out. It's bulky, heavy and the cleaning heads are crap - hair gets caught in the head and its so big it can't go under any furniture. I had a Dyson before and it was far superior. For the price I paid I expect a lot more.

Rubbish stay away sensor comes on every thirty seconds. I have washed the filters endlessly with the same issue. I'm sure Bosch are aware of this issue as you can see on this site by other customers. Bosch I will never buy one of your appliances again or recommend it to anyone.

Worst vacuum I have even turned on, I purposely purchased it because it had the wider hose, I spend more time Jamming something up the end of it to unblock it than I do vacuuming the floor. I have wanted to throw it in the fire many times. I know that if I return it to Harvey Norman that they will tell me that the filters are dirty or some other crap excuse instead of simply, we sold you a piece of crap.

Very disappointed in this unit, paid $800. Researched for a good vacuum that would vacuum pet hair off carpet. This unit said perfect for pet owners yeah right. IT IS HOPELESS i have to keep going over and over and does NOT remove the hair or anything. After i brush with my foot and heaps more hair comes out. Yes i have cleaned the head the suction is strong but doesnt vacuum. VERY NOISY not like its advertised very quiet. Only good for my tiled areas but like i said very noisy. About to throw in the bin only had for a year and im over it. Had a bosch before and didnt last long that was $450 i should of NEVER gone with this brand again. IF YOU HAVE A PET DONT DONT DONT get this unit

Went shopping pretty certain I would come home with a Dyson but after testing several brands in the store the Bosch was a clear winner. Big winner was the noise level, just so much quieter than the rest, and now having used it for 2 weeks I am more than happy with the results. The filtration is excellent and cleaning is a simple task. Well done Bosch.

This overall this is the best vacuum I have used extremely quite and powerful much better cleaning power then mybold Dyson the only downfall is the filter in the bin catches more dust then the bin itself and requires cleaning after each use old dyson didn't so close to a perfect vacuum I would of given 5 stars if filter setup was better.

I have used Dysons and whilst they are impressive nothing beats German engineering. This thing will lift the carpet off the floor and picked up a huge amount of dust from carpets vacuumed only a day prior. Easy to empty and very well thought out with a range of attachments provided best machine I have ever owned!
