Powershell delete all users in OU - powershell

Question

I am trying to delete all users within an OU using powershell, I have the below which gets stuck when it comes to the SAMAccount name, I want it to delete all the found users.
What am I doing wrong here please?
$search="OU=Staff,OU=Users,DC=Testing, DC=Local"
$deletes= Get-ADUser -SearchBase $search -filter * -properties SamAccountName | Select-Object SamAccountName
$numusers=($deletes.count)
echo "$numusers Users Found"
foreach ($delete in $deletes)
{
echo "Deleting user account $delete . . . "
remove-aduser -identity $delete -confirm:$false
}
This is the output. Seemingly going wrong here -- Cannot convert the "#{SamAccountName=bbonhomme}"
7 Users Found
Deleting user account #{SamAccountName=bbonhomme} . . .
Remove-ADUser : Cannot bind parameter 'Identity'. Cannot convert value "#{SamAccountName=bbonhomme}" to type
"Microsoft.ActiveDirectory.Management.ADUser". Error: "Cannot convert the "#{SamAccountName=bbonhomme}" value of type
"Selected.Microsoft.ActiveDirectory.Management.ADUser" to type "Microsoft.ActiveDirectory.Management.ADUser"."

Replace the
$deletes= Get-ADUser -SearchBase $search -filter * -properties SamAccountName | Select-Object SamAccountName
by
$deletes= Get-ADUser -SearchBase $search -filter * -properties SamAccountName
Adding Select-Object implies converting ADUser "object" to "Psobject". By consequence subsequent command remove-ADuser does not recognize this type of object.
Replace also :
remove-aduser -identity $deletes -confirm:$false
By
remove-aduser -identity $delete.SamAccountName -confirm:$false
changed $deletes by $delete (you cannot specify a collection in -Identity parameter)
