Where can I buy a small vacuum at a decent price in Lausanne?

In a shop.

I know I can get them in the shops. I wanted to know which shop has them at the best price.

How small is small .... small in size, or small in power?

Floor running or hand held?

Mains powered or rechargeable batteries?

Bag or bagless?

How much floor space needs to be cleaned .... tiles, wood or carpet?

What's a decent price, or best price .... good value for money, or cheap as in little money? One with few or many attachments.

Do you need a good guarantee and after sales service?

And ..... have you actually looked in any shops yourself??

I know we sometimes sound unhelpful on here, but a vacuum cleaner is not the sort of thing I buy every day and once I have one, I really don't check the prices until time comes round for a new one again - and I certainly don't check the price of one model against another in various shops.

The previous poster has also added the questions necessary to give you a answer which is anything but vague.
