i bought my 4th electric mower when i moved into my present house in 2016. it was cheap--works fine..but that damn cord really held things up.
this summer i bought a swift 40 volt cordless--and can mow my lawn in 20 mins...which is just about how long the charge lasts.
the mower seems very well made and tough. i paid £85 ( UK pounds ) for it--so i got quite a bargain...the battery alone costs that much ! it takes about 4 hours to charge. I almost like mowing the lawn now. i definitely recommend it.
i then bought a cheap Beldray stick vacuum cleaner--cordless. about £60 in tesco's. does the whole house on one charge..but i tend to use it instead of a dust pan and brush
