SEBO auto x vacuum - hard to push?
We have been delighted with our vacuum cleaner over a number of years, but recently it has become heavy to push and can't seem to sense whether it is on carpet of hard floor, suggesting that the Active Height Adjustment System is not functioning correctly.
We have changed the filters, bag and sensor strip but this hasn't made a difference - please can you advise whether there is anything else we can do?
