Not a warning but sensible advice to my neighbor using a puny electric 1000 PSI electric pressure cleaner to pressure clean his small driveway and sidewalk area.
We live in a gated community and the HOA requires the homeowner to clean the driveway and sidewalk around ones property. Here in Florida the humidity is terrible and pavers/sidewalks get filthy black from mildew requiring at least twice a year cleaning.
I had a similar machine and sold it and switched to a 3000 PSI gas powered unit and purchased a caster surface cleaner well worth the $67 cause in combination with the higher PSI washer the cleaning chores get cut down to a good 1/4 of the time using an electric cleaner and NO surface cleaner as my neighbor does.
I suggested last year to upgrade or to at least get a surface cleaner rated for his lower PSI unit that will cut down his work time by over half. Well, he’s been out there for the last 2 days pressure cleaning an area that with a higher PSI unit and surface cleaner would have taken him TOPS 4-5 hours.
