I bought the first one in about 1995 and it worked fine for years until one I got home and the motor had popped out the locking clamp, rotated and fallen on the carpet where it must have just buzzed away for an unknown length of time.
By then Swish had sold the brand to Silent Gliss and it has been obsolete for many years, motors are no longer available. Luckily B&Q sold off their unsold stock for peanuts so I got another control unit and motor and silly money. The gearbox in that motor has now failed. The gear teeth are black plastic molded onto brass centres and one has simply fallen off in two semi circles.
The motor is marked "ITT automotive 24V 404.095 31/95" and I have found a site in Switzerland that has 16 new ones for sale that look almost identical.
Trouble is this site has many scam warnings and you have to create an account.
Has anyone bought anything online from Switzerland (or is the seller in Italy) since Brexit ?.
